Which of the following equations matches the function shown above?

Answer:

g(x) = x^2 - 11x + 26

Step-by-step explanation:

In translation of functions, adding a constant to the domain values (x) of a function will move the graph to the left, while subtracting from the input of the function will move the graph to the right.

Given the function;

f(x) = x2 - 3x - 2

a shift 4 units to the right implies that we shall be subtracting the constant 4 from the x values of the function;

g(x) = f(x-4)

g(x) = (x - 4)^2 - 3(x - 4) -2

g(x) = x^2 - 8x + 16 - 3x + 12 - 2

g(x) = x^2 - 11x + 26

Answer:

g(x) = (x+4)^2 - 3x - 2

Step-by-step explanation:

In this question , apply Pythagorean relationship

Lets assume ;the climbing, sliding and walking back to the base forms a right-angle triangle

The tower height = the height of the triangle, h=60f

The sliding lane= the hypotenuse of the triangle=?

\

The distance covered to the base= base of the triangle=80f

Applying the relation ;

a²+b²=c²

80²+60²=c²

6400+3600=c²

10000=c²

√10000=c

100=c

Distance traveled in all=100+60+80=240 feet

Zachary traveled a total of 140 feet including climbing the tower and walking back from the splash pool to the tower.

The question is asking how far Zachary has traveled in total. He first climbs a 60-foot tower and then he lands in the splash pool. After that, he walks 80 feet back to the base of the tower.

To find the total distance he traveled, we need to add the distance he climbed up the tower to the distance he walked back to the tower. This can be done using simple addition.

Therefore, the total distance= distance climbed + distance walked = 60 feet + 80 feet = 140 feet.

So, Zachary traveled a total of 140 feet in all.

Answer:

x= 1.8

Step-by-step explanation:

We have been given the equation;

-(6)^(x-1)+5=(2/3)^(2-x)

We are required to determine the value of via graphing. To do this we can split up the right and the left hand sides of the equation to form the following two separate equations;

y = -(6)^(x-1)+5

y = (2/3)^(2-x)

We then proceed to graph the two equations on the same graph. The solution will be the point where the equations will intersect. Find the attachment below for the graph;

The value of x is 1.785. To the nearest tenth we have x = 1.8

Question 1:

For this case we have that by definition, the GCF of two numbers is the largest number that is a factor of both numbers. For example, the number 10 is the biggest factor that 50 and 30 have in common.

We must find the GCF of the following expression:

[tex]30t ^ 2u + 12tu ^ 2 + 24tu[/tex]

We look for the prime factorization of each number:

[tex]30: 2 * 3 * 5\\12: 2 * 2 * 3\\24: 2 * 2 * 2 * 3[/tex]

The GCF of the three numbers is [tex]2 * 3 = 6[/tex]

So:

Answer:

Option C

Question 2:

For this case we have that by definition of power properties of the same base, that:

[tex]a ^ n * a ^ m = a ^ {n + m}[/tex]

That is, for multiplication of powers of the same base, the same base is placed and the exponents are added.

So:

[tex]b ^ n * b ^ m = b ^ {n + m}[/tex]

ANswer:

[tex]b ^ {n + m}[/tex]

Option A

The greatest common factor of the expression is 6tu, and the factored form is 6tu(5t + 2u + 4), . For the property of exponents, the rule is that when multiplying powers with the same base, you add the exponents, yielding an answer of  b^n+m.

15.The correct option is (C) and 16.The correct option is (A).

To solve the problem factor out the greatest common factor from the expression 30t2u + 12tu2 + 24tu, we have to look for the highest power of each variable and the largest number that can divide each term. The greatest common factor for this expression is 6tu.

Factoring out 6tu gives us:

The correct answer is C. 6tu(5t + 2u + 4).

For the property of exponents problem, when multiplying powers with the same base, you add the exponents. So, bn · bm = bn+m.

The correct answer is A. bn+m.

Step-by-step explanation:  Given that for a school fundraiser, Jeff sold large boxes of candy for three dollars each and small boxes of candy for two dollars each.

Also, Jeff sold 37 boxes in all for total of $96.

We are to find the number of large boxes more than that of small boxes.

Let x and y represents the number of large boxes and small boxes respectively.

Then, according to the given information, we have

[tex]x+y=37~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\3x+2y=96~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]

Multiplying equation (i) by 2 and subtracting from equation (ii), we get

[tex](3x+2y)-(2x+2y)=96-37\times2\\\\\Rightarrow x=96-74\\\\\Rightarrow x=22.[/tex]

From equation (i), we get

[tex]22+y=37\\\\\Rightarrow y=37-22\\\\\Rightarrow y=15.[/tex]

We have,

[tex]x-y=22-15=7.[/tex]

Thus, there are 7 more large boxes than small boxes.

Option (A) is CORRECT.

Answer:

π/49·(44 -π)

Step-by-step explanation:

Using the "shell" method, a differential of volume is the product of the area of a cylindrical shell and its circumference around the axis of rotation. Here, that area is ...

dA = y·dx = cos(7x)dx

The radius will be the difference between x and the axis of rotation, x=3, so is ...

r = 3 -x

Then the differential of volume is ...

dV = 2πr·dA = 2π(3-x)cos(7x)dx

The volume will be the integral of this over the limits x ∈ [0, π/14].

∫dV = 6π·∫cos(7x)dx -2π·∫x·cos(7x)dx . . . from 0 to π/14

= (6/7)π·sin(7x) -(2/49)π·(cos(7x) +7x·sin(7x)) . . . from 0 to π/14

= (6/7)π(1 -0) -(2/49)π((0 -1) +(π/2-0))

= π(42/49 +2/49 -π/49)

= (π/49)(44 -π) . . . . cubic units . . . . . approx 2.61960 cubic units

Final answer:

The volume of the solid created by rotating the bounded region about the axis x=3 is found using cylindrical shells and evaluating the integral from x=0 to x=π/14 of the expression 2π(3-x)cos(7x)dx.

Explanation:

To find the volume of the solid obtained by rotating the region bounded by the curves y=0, y=cos(7x), x=π/14, and x=0 about the axis x=3, we need to use the method of cylindrical shells.

For a small strip at position x with height y and thickness dx, rotating around x=3 creates a cylindrical shell with circumference 2π(3-x), height cos(7x), and thickness dx.

The volume of each shell is V = 2π(3-x)cos(7x)dx, and summing these from x=0 to x=π/14 gives us the total volume.

So, the volume V is the integral:

∫0π/14 2π(3-x)cos(7x)dx.

This volume is found by evaluating the definite integral.

Answer:

Number of adult tickets = 3 tickets

Number of children tickets = 5 tickets

Step-by-step explanation:

A- The system of equations:

Assume that the number of adult tickets is x and that the number of children tickets is y

We are given that:

i. The total number of people in the group is 8, which means that the total number of tickets bought is 8. This means that:

x + y = 8 ..................> equation I

ii. The price of an adult ticket is $12 and that of a child ticket is $10. We know that the group spent a total of $86. This means that:

12x + 10y = 86 ...............> equation II

From the above, the systems of equation is:

x + y = 8

12x + 10y = 86

B- Solving the system using elimination method:

Start by multiplying equation I by -10

This gives us:

-10x - 10y = -80 .................> equation III

Now, taking a look at equations II and III, we can note that coefficients of the y have equal values and different signs.

Therefore, we will add equations II and III to eliminate the y

    12x + 10y = 86

+( -10x - 10y = -80)

Adding the two equations, we get:

2x = 6

x = 3

Finally, substitute with x in equation I to get the value of y:

x + y = 8

3 + y = 8

y = 8 - 3 = 5

Based on the above:

Number of adult tickets = x = 3 tickets

Number of children tickets = y = 5 tickets

C- Explanation of the meaning of the solution:

The above solution means that for a group of 8 people to be able to spend $86 in a theater having the price of $12 for an adult ticket and $10 for a child' one, this group must be composed of 3 adults and 5 children

Answer:

24cm and 225cm

Step-by-step explanation:

Answer:

1) [tex]24cm^2[/tex]

2) [tex]30cm[/tex]

Step-by-step explanation:

1) Remember that: The area of a quadrilateral circumscribed about a circle equals  semi-perimeter (half the product of the perimeter of the quadrilateral) and the radius of the circle.  

By the other hand in a quadrilateral circumscribed the sum of the measures of any pair of two opposite sides is equal to the sum of the measures of the other pair of the opposite sides.

Then you know that the sum of all sides should be 12cm+12cm=24cm

Area= Semi-perimeter*r

where

Semi-perimeter= perimeter/2= sum of all sides/2

r= radius of the circle

Then:

[tex]Area=(24cm/2)*(2cm)= 24cm^2[/tex]

2) Perimeter= sum of all sides

And as the sum of the measures of any pair of two opposite sides is equal to the sum of the measures of the other pair of the opposite sides.

Perimeter=15cm+15cm=30cm

Step-by-step explanation:

First we need to find which function is the outside radius and which is the inside radius (by which I mean which is farther and which is closer to the axis of rotation).  We can do this by graphing, but we can also do this by evaluating each function at the end limits.

At x = 0:

y = 5 sin 0 = 0

y = 5 cos 0 = 5

At x = π/4:

y = 5 sin π/4 = 5√2 / 2

y = 5 cos π/4 = 5√2 / 2

So y = 5 cos x is the outside radius because it is farther away from y = -1, and y = 5 sin x is the inside radius because it is closer to y = -1.

Here's a graph:

desmos.com/calculator/5oaiobcpww

The volume of the rotation is:

V = π ∫ₐᵇ [(R−y)² − (r−y)²] dx

where a is the lower limit, b is the upper limit, R is the outside radius, r is the inside radius, and y is the axis of rotation.

Plugging in:

V = π ∫₀ᵖ [(5 cos x − -1)² − (5 sin x − -1)²] dx

V = π ∫₀ᵖ [(5 cos x + 1)² − (5 sin x + 1)²] dx

V = π ∫₀ᵖ [(25 cos² x + 10 cos x + 1) − (25 sin² x + 10 sin x + 1)] dx

V = π ∫₀ᵖ [25 cos² x + 10 cos x + 1 − 25 sin² x − 10 sin x − 1] dx

V = π ∫₀ᵖ [25 (cos² x − sin² x) + 10 cos x − 10 sin x] dx

V = π ∫₀ᵖ [25 cos (2x) + 10 cos x − 10 sin x] dx

V = π [25/2 sin (2x) + 10 sin x + 10 cos x] from 0 to π/4

V = π [25/2 sin (π/2) + 10 sin (π/4) + 10 cos (π/4)] − π [25/2 sin 0 + 10 sin 0 + 10 cos 0]

V = π [25/2 + 5√2 + 5√2] − 10π

V = π (5/2 + 10√2)

V ≈ 52.283

In this exercise it is necessary to calculate the volume of the rotating solid, in this way we have:

[tex]V= 52.3[/tex]

First we need to find which function is the outside radius and which is the inside radius (by which I mean which is farther and which is closer to the axis of rotation).  We can do this by graphing, but we can also do this by evaluating each function at the end limits.

[tex]x=0\\y=5sin(x)\\y=5sin(0)=0\\y=5cos(0)= 5\\\\x=\pi/4\\y=5sin(\pi/4)= 5(\sqrt{2/2})\\y=5cos( \pi/4)= 5/\sqrt{2}[/tex]

So [tex]y = 5 cos x[/tex] is the outside radius because it is farther away from y = -1, and [tex]y = 5 sin x[/tex] is the inside radius because it is closer to y = -1. Here's a graph (first image). The volume of the rotation is:

[tex]V=\pi\int\limits^a_b {[(R-y)^2-(r-y)^2]} \, dx[/tex]

Where a is the lower limit, b is the upper limit, R is the outside radius, r is the inside radius, and y is the axis of rotation. Plugging in:

[tex]V=\pi\int\limits^a_b {[(R-y)^2-(r-y)^2]} \, dx\\= \pi\int\limits^p_0 {[(5 cos(x) + 1)^2-(5 sin(x) + 1)^2]} \, dx\\=\pi\int\limits^p_0 {[(25 cos^2 (x) + 10 cos (x) + 1)-(25 sin^2 (x) + 10 sin (x) + 1)]} \, dx\\=\pi\int\limits^p_0 {[(5 cos^2 (x) + 10 cos (x) + 1 -25 sin^2 (x)- 10 sin (x)- 1]} \, dx\\=\pi\int\limits^p_0 {[(25 (cos^2( x)- sin^2( x)) + 10 cos( x)- 10 sin( x)]} \, dx\\=\pi\int\limits^p_0 {[(25 cos (2x) + 10 cos (x)- 10 sin (x)]} \, dx\\[/tex]

Answer:

[tex]127,000\ members[/tex]

Step-by-step explanation:

In this problem we have an exponential function of the form

[tex]f(x)=a(b)^{x}[/tex]

where

a is the initial value

b is the base

The base is equal to

b=1+r

r is the average rate

In this problem we have

a=23,000 members

r=5%=5/100=0.05

b=1+0.05=1.05

substitute

[tex]f(x)=23,000(1.05)^{x}[/tex]

x ----> is the number of years since 1985

How many members will there be in 2020?

x=2020-1985=35 years

substitute in the function

[tex]f(x)=23,000(1.05)^{35}=126,868\ members[/tex]

Round to the nearest thousand

[tex]126,868=127,000\ members[/tex]

The club is expected to have about 126868 members in 2020.

[tex]\[N(t) = N_0 \times (1 + r)^t\][/tex]

In this problem:

[tex]- \( N_0 = 23,000 \)- \( r = 0.05 \) (5% growth rate)- \( t = 2020 - 1985 = 35 \)[/tex]

Substituting these values into the formula, we get:

[tex]\[N(35) = 23,000 \times (1 + 0.05)^{35}\][/tex]

[tex]\[N(35) = 23,000 \times (1.05)^{35}\][/tex]

[tex]\[(1.05)^{35} \approx 5.516\][/tex]

Now, multiply by the initial number of members:

[tex]\[N(35) = 23,000 \times 5.516 \approx 126,868\][/tex]

Answer:

14 years old

Explanation:

Use this system of equations if G=George and J=Jeannie:

G-12=J

50=(G+5)+(J+5)

So, change second equation becomes

40-G=J

Then use substitution:

G-12=40-G

2G=52

G=26

Then, to find Jeannie’s age, go back to one of the equations and substitute G.

26-12=J

So, J=14

Jeannie is currently 14 years old.

To solve any questions relating to ages, I find it easier to make a table, like in the picture below.

See picture for answer and clear diagram.

-----------------------------------------------------------------

Notes/Explanations + answer in written form

Jennies age now = x

So Georges age now would be: x + 12   (since he is 12 years older)

Jennies age in 5 years would be: x + 5   (since it is 5 years later)

Georges age in 5 years would be: x + 12 + 5 = x + 17

We are told that their ages in 5 years would add up to 50. So we can write an equation like so:

x + 17   +   x + 5 = 50                 (All you have to do now is solve it)

2x + 22 = 50                             (combine like terms)

2x = 28                                      (subtract 22 from both sides)

x = 14                                         (divide both sides by two)

That means that Jennies age is 14 years

Answer:

Step-by-step explanation:

The ratio of interest rates is 8% : 4% = 2 : 1. Since the amount of interest earned in each account is the same, the ratio of amounts invested will be the inverse of that, 1/2 : 1/1 = 1 : 2.

Then 1/(1+2) = 1/3 of the money is invested in the 8% account. That amount is ...

  $9102/3 = $3034 . . . . invested at 8%

The remaining amount is invested at 4%:

  $9102 - 3034 = $6068 . . . . invested at 4%

_____

The interest earned in 1 year in each account is

  0.08·$3034 = 0.04·$6068 = $242.72

_____

If you really need an equation, you can let x represent the amount invested at the higher rate. (Using this variable assignment avoids negative numbers later.) Then 9102-x is the amount invested at the lower rate.

  0.08x = 0.04(9102-x)

  0.12x = 0.04·9102 . . . . . eliminate parentheses, add 0.04x

  x = (0.04/0.12)·9102 = 9102/3 . . . . . divide by the coefficient of x. Same answer as above.

The correct statement is: Angle G is congruent to angle P.

Congruency in geometry refers to the similarity between two shapes or figures. When two shapes are congruent, their corresponding angles and sides are equal in measure, preserving the same shape and size but allowing for possible reflection or rotation.

The correct statement that compares the angles is: Angle G is congruent to angle P. Congruent angles are angles that have the same measure. So, if angle G is congruent to angle P, it means that they have the same measure. For example, if angle G measures 30 degrees, then angle P would also measure 30 degrees.

In mathematics, the sine function is a trigonometric function that relates the angles of a right triangle to the ratios of the side lengths. The value of sin(K) depends on the value of angle K, which is measured in radians.

For example, if K = π/2, then sin(K) = 1. If K = 0, then sin(K) = 0.

To find the value of sin(K), you can use a calculator or reference table that provides the values of sine for different angles.

1. a. 25(1) + 10(2) + 3(3) + 10(4) = 94/140 = .671

2. b. Mark’s average < Jay’s average

Step-by-step explanation:

1. What is Mark’s slugging average?

The slugging average gives more weight to the multi-base hits (compared to single-base hits) in opposition with the batting average.

So, a single hit is worth 1 point, a double is worth 2 points, a triple 3 points and a homerun is worth 4 points.  It's a weighted average calculation.

Mark had 25 singles, 10 doubles, 3 triples and 10 homeruns during 140 presences 140 at bat.

25(1) + 10(2) + 3(3) + 10(4) = 94/140 = .671

2. How does Mark's average compares to Jay's?

Let's first calculate Jay's slugging average then we'll be able to decide.

Jay had 10 singles, 6 doubles, 5 triples and 14 homeruns in 90 presences.

10 (1) + 6 (2) + 5 (3) + 14 (4) = 10+12+15+56 = 93 / 90 = 1.033

We can definitely say that Mark's slugging average (0.671) calculated above is lower than Jay's average (1.033).  So,

b. Mark’s average < Jay’s average

ANSWER

[tex]{x}^{3} - {y}^{3} = (x - y)[ {x}^{2} + xy + {y}^{2}][/tex]

EXPLANATION

We want to factor:

[tex] {x}^{3} - {y}^{3} [/tex]

completely.

Recall from binomial theorem that:

[tex]( {x - y)}^{3} = {x}^{3} - 3 {x}^{2} y + 3x {y}^{2} - {y}^{3} [/tex]

We make x³-y³ the subject to get:

[tex] {x}^{3} - {y}^{3} = ( {x - y)}^{3} + 3 {x}^{2} y - \:3x {y}^{2}[/tex]

We now factor the right hand side to get;

[tex]{x}^{3} - {y}^{3} = ( {x - y)}^{3} + 3 {x} y(x - y)[/tex]

We factor further to get,

[tex]{x}^{3} - {y}^{3} = (x - y)[( {x - y)}^{2} + 3 {x} y][/tex]

[tex]{x}^{3} - {y}^{3} = (x - y)[ {x}^{2} - 2xy + {y}^{2} + 3 {x} y][/tex]

This finally simplifies to:

[tex]{x}^{3} - {y}^{3} = (x - y)[ {x}^{2} + xy + {y}^{2}][/tex]

To factor the expression x³ - y³ completely, use the formula for factoring a difference of cubes: a³ - b³ = (a - b)(a² + ab + b²). Plug in x for a and y for b to get (x - y)(x² + xy + y²).

To factor the expression x³ - y³ completely, we can use the formula for factoring a difference of cubes. The formula is:

a³ - b³ = (a - b)(a² + ab + b²)

Using this formula, we can plug in x for a and y for b.

x³ - y³ = (x - y)(x² + xy + y²)

Therefore, the expression x³ - y³ can be factored completely as (x - y)(x² + xy + y²).

Answer:

5

Step-by-step explanation:

We can use the distance formula with 3 different vertices to figure out the shortest of the three sides.

The distance formula is [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Where (x_1,y_1) is the first points and (x_2,y_2) is the second set of points, respectively.

Now let's figure out the length of 3 sides.

1. The length between (-6,-5) & (-5,6):

[tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\=\sqrt{(6--5)^2+(-5--6)^2}\\ =\sqrt{(6+5)^2+(-5+6)^2} \\=\sqrt{11^2+1^2} \\=\sqrt{122}[/tex]

2. The length between (-6,-5) & (-2,2):

[tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\=\sqrt{(2--5)^2+(-2--6)^2} \\=\sqrt{(2+5)^2+(-2+6)^2}\\ =\sqrt{7^2+4^2}\\ =\sqrt{65}[/tex]

3. The length between (-5,6) & (-2,2):

[tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\=\sqrt{(2-6)^2+(-2--5})^2}\\ =\sqrt{(-4)^2+(3)^2} \\=\sqrt{25} \\=5[/tex]

Thus, length of the shortest side is 5.

Answer:

5 units

Step-by-step explanation:

Draw the triangle with the vertices given. Identify the smallest side and draw in a right triangle using the smallest side of the original triangle as the hypotenuse of the right triangle, as shown on the grids below.

The horizontal side of the small right triangle measures 3 units and the vertical side of the small right triangle measures 4 units.

Use the Pythagorean theorem to find the length of the hypotenuse.

Therefore, the length of the shortest side of the triangle measures 5 units.

3^2 + 4^2  =  c^2

9 + 16  =  c^2

25  =  c^2

5  =  c

Answer: False

Step-by-step explanation:

The measure of the created angle is equal to the difference of the measure of the arcs.

The angle formed by the intersection of a secant and a tangent is equal to half the measure of the intercepted arc, not the sum of the measures of the intercepted arcs.

The statement is False. The angle formed by the intersection of a secant and a tangent is half the measure of the intercepted arc, not equal to the sum of the measures of the intercepted arcs.

For example, let's consider a circle with a secant and a tangent line intersecting at a point. The intercepted arc is represented by the section of the circumference between the two points of intersection. The angle formed by the intersection of the secant and the tangent is equal to half the measure of this intercepted arc.

So, in conclusion, the angle formed by the intersection of a secant and a tangent is equal to half the measure of the intercepted arc.
