Answer 2

The value of the limit is 4.5 .

What is limit?

An output value that a function approaches for the specified input values is referred to as a limit.

Calculus and mathematical analysis depend on limits, which are also used to determine integrals, derivatives, and continuity.

The given limit is,

F(x) = [tex]lim_{x- > 0} (e^{3x}-3x-1)/x^2[/tex]

Differentiate with respect to x,

F'(x) = [tex]lim_{x- > 0} d/{dx}(e^{3x}-3x-1)/x^2[/tex]

= [tex]lim_{x- > 0} d/{dx}(e^{3x}-3x-1)/d/dx(x^2)[/tex]

= [tex]lim_{x- > 0}\ 3e^{3x}-3/2x[/tex]

Differentiate again with respect to x,

F''(x) = [tex]lim_{x- > 0}\ d/dx(3e^{3x}-3/2x)[/tex]

= [tex]lim_{x- > 0} (9e^{3x)}/2}[/tex]

= [tex]9 .e^0/2[/tex]

= [tex]9/2[/tex]

= [tex]4.5[/tex]

The limit of the function is 4.5 .

B is between a and c ac=15.8 and ab=9.9. find bc

Answers

Answer:

The value of bc is 5.9 units.

Step-by-step explanation:

Given information: b is between a and c, ac=15.8 and ab=9.9.

We need to find the measure of bc.

Since b is between a and c, therefore the segment ac is the sum of two segments ab and bc.

[tex]ac=ab+bc[/tex]

Substitute ac=15.8 and ab=9.9 in the above equation.

[tex]15.8=9.9+bc[/tex]

Subtract 9.9 from both sides.

[tex]15.8-9.9=9.9+bc-9.9[/tex]

[tex]5.9=bc[/tex]

Therefore the value of bc is 5.9 units.

If assumption of Collinearity is not for granted, then the length of Segment BC is defined by [tex]BC = \sqrt{347.65 -312.84\cdot \cos \beta}[/tex], for [tex]\beta \in [0^{\circ}, 180^{\circ}][/tex].

Reminder - Given that statement seems to be incomplete, we assume that we are talking about Line Segments and that Segments AC and BC may be Collinear.

By Geometry and, being more specific, by definition of Triangles, if we assume that all segment are not necessarily Collinear, then a Triangle may exist and can be modelled by the Law of Cosine:

[tex]BC = \sqrt{AC^{2}+AB^{2}-2\cdot AC\cdot AB\cdot \cos \beta}[/tex] (2)

Where [tex]\beta[/tex] is the angle at point B, in sexagesimal degrees and is between 0° and 180°.

If we know that [tex]AC = 15.8[/tex] and [tex]AB = 9.9[/tex], then the expression for the length of BC is:

[tex]BC = \sqrt{347.65 -312.84\cdot \cos \beta}[/tex]

Given the arithmetic sequence an = −1 + 7(n − 1), what is the domain for n?

All integers
All integers where n ≥ 0
All integers where n ≥ 1
All integers where n > 1

Answers

Final answer:

The domain for n in the arithmetic sequence is all integers where n ≥ 1.

Explanation:

The domain for n in the arithmetic sequence is all integers where n ≥ 1. In this sequence, the value of n represents the position of the term in the sequence. Since the first term of the sequence is represented by n=1, n can't be less than 1 because there is no zeroth term in the sequence. Therefore, the domain for n is all integers where n ≥ 1.

Describe how to determine if two polygons have the same size and shape.

Answers

You can identify similar polygon by comparing their corresponding angles and sides. ( if they are the same the ratio of the lengths is the scale factor. Also check if their sides are proportional.)

Answer:

Prove that their corresponsing sides are all congruents

Step-by-step explanation:

Remember that if two figures have corresponding angles congruent, but proportional sides, then those figures are similar.

However, if those figures have corresponding angles and sides congruent, then they are congruent.

Therefore, to determine if two polygons are congruent, that is, in size and shape, we need to prove that their corresponsing sides are all congruents, that way, we'll be able to demonstrate their absolute congruence.

Interpret the average rate of change of –14/3 that you found previously. What does this mean in terms of the waterslide, from x = 0 to x = 15?

Answers

Solution: The average rate of change of [tex]\frac{-14}{3}[/tex] represents that the second variable is decrease by 14 if the first variable increase by 3. In terms of water slide the vertical height of slide is decreased at the rate of 4.66 per unit. The vertical height of the slide decrease 70 units from x = 0 to x = 15.

Explanation:

The rate of change shows the change in first variable with respect to change in second variable.

If the rate of chang is given by [tex]\frac{-14}{3}[/tex] it means second variable is decrease by 14 if the first variable increase by 3.

In the context of water slide it shows that the vertical height of slide is decreased by 14 units as we cover the distance of 3 units.

If we cover the distance from x = 0 to x = 15, it means we cover the distance of 15 units.

Let the vertical height of the slide covered from x = 0 to x =15 be y.

It means when distance increased by 15 units the height of slide decreased by y units.

So rate of change = [tex]\frac{-y}{15}[/tex].

It is given that the rate of change is [tex]\frac{-14}{3}[/tex].

Equate both equations.

[tex]\frac{-y}{15}=\frac{-14}{3}[/tex]

[tex]y=15(\frac{14}{3} )[/tex]

[tex]y=5(14)[/tex]

[tex]y=70[/tex]

Therefore, the average rate of change of [tex]\frac{-14}{3}[/tex] represents that the second variable is decrease by 14 if the first variable increase by 3. In terms of water slide the vertical height of slide is decreased at the rate of 4.66 per unit. The vertical height of the slide decrease 70 units from x = 0 to x = 15.

What this mean in terms of the waterslide, from x = 0 to x = 15 is:

The vertical height of slide is decreased at the rate of 4.66 per unit.The vertical height of the slide decreased by 70 units from x= 0 to x=15

What is Rate of Change?

This refers to how fast or slow a thing is required before it changes form from one form to another.

With this in mind, we can see that with the water slide, there exists the decrease of the vertical height by 14 units over a distance of 3 units.

Therefore, the rate of change is -y/15

In addition to the trigonometric ratios, what other methods can be used to solve a right triangle? Give situations for when you might want to use them

Answers

Consider the right triangle shown below.
We shall discuss two methods for solving the right triangle.

Method 1. Use of trigonometric ratios
To use trigonometric ratios requires that either m∠A or m∠B is known and that one of the sides a, b, or c is known.
Example:
Assume that m∠A is known, then m∠B = 90° - m∠A.
Also, assume that b is known.
By definition,
tan A = a/b => a = b*tan A
cos A = b/c => c = b/cos A, or
sin A = a/c => c = a/sin A

Method 2. Algebraic method
When neither m∠A nor m∠B is known, then it is necessary to know the values of two sides: (a and b), (a and c), or (b and c).
The Pythagorean theorem states that
a² + b² = c²
(a) If a and b are known, then
c = √(a² + b²)
(b) If a and c are known, then
b = √(c² - a² )
(c) If b and c are known, then
a = √(c² - b²)

Once all sides are known, trigonometric ratios can be used t determine m∠A and m∠B.
Example:
Because a and c are known,
sin A = a/c
A = sin⁻¹ (a/c), which can be determined from the calculator.

Marion is observing the velocity of a cyclist at different times. After two hours, the velocity of the cyclist is 18 km/h. After four hours, the velocity of the cyclist is 4 km/h. Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist at different times. Show your work and define the variables used. (5 points) Part B: How can you graph the equations obtained in Part A for the first 8 hours? (5 points)

Answers

Assume that the velocity is a linear function of time, so that
v(t) = a + bt
where
v = velocity (km/h) at time t (hours),
a and b are constants.

When t = 2 hours, v = 18 km/h, therefore
a + 2b = 18 (1)

When t = 4 hours, v = 4 km/h, therefore
a + 4b = 4 (2)

Subtract (1) from (2) to obtain
a + 4b - (a + 2b) = 4 - 18
2b = -14
b = -7
From (1), obtain
a = 18 - 2b = 18 - 2*(-7) = 32

Part A.
The equation is
v = 32 - 7t

Part B
To graph the equation for the first 8 hours, create a table as shown below.
t, hours: 0 1 2 3 4 5 6 7 8
v, km/h: 32 25 18 11 4 -3 -10 -17 -24

We can see from the table that the velocity becomes negative between t=4 and t=5. Therefore, we shall change all negative velocities to zero, and assume that the cyclist comes to rest.
TNote that when the velocity is zero,
32 - 7t = 0
7t = 32
t = 4.57

The new table becomes
t: 0 1 2 3 4 4.57 5 6 7 8
v: 32 25 18 11 4 0 0 0 0 0

Step-by-step explanation:

Givens:

[tex]f(x)=830(0.8)^{x}[/tex]; where [tex]x[/tex] refers to years after the study began, about bear population.Table given is for cougar population.

So, the problem is asking how many more bears than cougars were in the given region. From the table, we know that there where 790 cougar when the study started.

Now, we have to calculate the initial condition of the function, because it's modelling bear population. Initial condition means when the study started, which is when [tex]x=0[/tex].

So, we have:

[tex]f(0)=830(0.8)^{0}=830(1)=830[/tex]

So, there were 830 bears when the study started.

If we compare, we find that there were 40 more bears than cougars when the study started, because 830-790 = 40.

Which best explains if quadrilateral WXYZ can be a parallelogram?

WXYZ can be a parallelogram with one pair of sides measuring 15 mm and the other pair measuring 9 mm.
WXYZ can be a parallelogram with one pair of sides measuring 15 mm and the other pair measuring 7 mm.
WXYZ cannot be a parallelogram because there are three different values for x when each expression is set equal to 15.
WXYZ cannot be a parallelogram because the value of x that makes one pair of sides congruent does not make the other pair of sides congruent.

Answers

Your answer is
"WXYZ can be a parallelogram with one pair of sides measuring 15mm and the other pair measuring 9mm"

To find this, you first have to solve for x. Assuming WXYZ is a parallelogram, then the side (x + 8) must equal 15, which means we can subtract 8 and get x as 7.

Now we substitute 7 into the other side's, (7 + 2) = 9mm, and (7 × 2) - 5 = 14 - 5 = 9mm.

I hope this helps!

If quadrilateral WXYZ is a parallelogram, the opposite sides will be equal, in length from which the value of x will satisfy the two equations.

Response:

WXYZ can be a parallelogram with one pair of sides measuring 15 mm and the other pair measuring 9 mm.

How can the option that best indicates if WXYZ can be a parallelogram be obtained?

Properties of a parallelogram

The length of the opposite sides of a parallelogram are equal, which gives;

2·x - 5 = x + 2

2·x - x = 2 + 5

x = 7

Similarly, we have;

x + 8 = 15

x = 15 - 8 = 7

The lengths of the opposite sides are therefore;

2·x - 5 = 2 × 7 - 5 = 9 and x + 8 = 15

The option that indicates if WXYZ is a parallelogram is therefore;

WXYZ can be a parallelogram with one pair of sides measuring 15 mm and the other pair measuring 9 mm.

A.) 12 inches

B.) 15 inches

C.) 30 inches

D.) 36 inches

Answers

A = 1/2 * b * h
A = 180
b = z
h = 2z + 6

180 = 1/2 * z * 2z + 6
180 = (2z^2 + 6z)/ 2
180 = z^2 + 3z)
z^2 + 3z - 180 = 0
(z - 12)(z + 15) = 0

z - 12 = 0
z = 12

z + 15 = 0
z = -15....not this one because it is negative

h = 2z + 6
h = 2(12) + 6
h = 24 + 6
h = 30 inches <====

The formula for area of a triangle = BH / 2
In which the area = 180 square inches.

You can therefore make this formula:

180 = [2(2z+6)+6](2z+6) / 2

Now solve for z.

360 = [2(2z+6)+6](2z+6)
360 = (4z+12+6)(2z+6)
360 = (4z+18)(2z+6)
360 = 8z^2 + 24z + 36z + 108
360 = 8z^2 + 60z + 108
0 = 8z^2 + 60z - 252

Now we will use quadratic formula to get z = 3, -21/2

Substitute in now

2(2z+6) + 6
2(2(3)+6) + 6
2(6+6) + 6
2(12) + 6

2.

the sum of the interior angles of a heptagon is (7-2)180°=5*180°=900°

let the measures of the interior angles be a,b,c,d,e,f and g.

so a+b+c+d+e+f+g=900°

the exterior angle measures are 180-a, 180-b, 180-c, 180-d, 180-e, 180-f, 180-g,

so the sum of the measure angles of the exterior angles is

(180°-a)+(180°-b) +(180°-c)+(180°-d)+(180°-e)+(180°-f)+(180°-g)
= 180°*7-(a+b+c+d+e+f+g)=1260°-900°=360°.

In fact, the sum of the measures of the exterior angles of any polygon is 360°.

1. Let the length of the second base be x

then

x+24=38
x=38-24=14 units

Given the following geometric sequence, find the common ratio. {0.1,-0.9,8.1,...}

Answers

The common ratio is the constant found when you divide any term in a geometric sequence by the term preceding it.

-0.9/0.1=8.1/-0.9=-9

The common ration is negative 9.

Answer:

Common ratio, r = -9

Step-by-step explanation:

If we have geometric progression, the common ratio is the ratio of (n+1)th term and nth term.

Here geometric progression is

0.1,-0.9,8.1,.................

Common ratio

[tex]r=\frac{-0.9}{0.1}=-9\\\\r=\frac{8.1}{-0.9}=-9[/tex]

Common ratio, r = -9

If 9a+5b+5c=9 what is -10c-18a-10b?

Hence, the answer is -18.

On her first stroke, Maria hit a golf ball 140 yards, 2 feet, 9 inch. On her second she hit it 170 yards, 1 foot, 6 inches. How far did the ball go all together

Answers

2 feet 9 inches + 1 foot 6 inches = 3 feet 15 inches

15 inches = 1 foot 3 inches

3 feet + 1 foot = 4 feet

2 ft 9 inches + 1 ft 6 inches = 4 ft 3 inches

1 yard = 3 feet

4feet 3 inches = 1 yard, 1 foot 3 inches

140+170 = 310 yards

310 + 1 = 311

so it traveled 311 yards 1 foot and 3 inches

Answer:

311 yards and 1 feet and 3 inches
