Also explain step by step how to solve these problems please

Answers

Answer 1
28g^5h^2 and 12g^6h^5

first, we find the GCF of the coefficients 28 and 12. What is the highest number that will go into both 28 and 12 evenly ? That number is going to be 4.

now, we look at our variables....to find the GCF of the variables, pick the lowest exponent.
another words, the lowest exponent of ur variable h is h^2...and the lowest exponent of ur variable g is g^5

therefore, the GCF of these monomials is : 4h^2g^5

Joe the trainer has two solo workout plans that he offers his clients: Plan A and Plan
b. Each client does either one or the other (not both). On Monday there were 2 clients who did Plan A and 3 who did Plan
b. On Tuesday there were 4 clients who did Plan A and 8 who did Plan
b. Joe trained his Monday clients for a total of 7 hours and his Tuesday clients for a total of 17 hours. How long does each of the workout plans last?

Answers

Let workout Plan A last a hours, and Plan B last b hours.

we are assuming personal training for each client.

i)
"On Monday there were 2 clients who did Plan A and 3 who did Plan"

the total time spent is : 2*a + 3*b =2a+3b

ii)
"On Tuesday there were 4 clients who did Plan A and 8 who did Plan B"

the total time spent was 4*a+8*b=4a+8b

iii) "Joe trained his Monday clients for a total of 7 hours"

so 2a+3b = 7

iv)

"Joe trained his Tuesday clients for a total of 17 hours"

so 4a+8b=17

v) thus we have the following system of equations:

2a+3b = 7
4a+8b=17

multiply the first equation by -2, and then add both equations, to eliminate a:

-4a-6b=-14
4a+8b=17
-------------------
2b=3, so b=3/2

2a+3b = 7
2a+3(3/2)=7
2a+9/2=7
multiply by 2:
4a+9=14
4a=5
a=5/4

Answer :

Plan A lasts 5/4=1.25 h
Plan B lasts 3/2=1.5 h


Use the pythagorean theorem to find the distance between x(7,11) and y(-1,5)..

Answers

so, if the legs are a and b and the hypothuse is c then
a²+b²=c²

the distance bewteen the points is the hyptohuse

the legs are the distances between th x and y values

so
(7,11) and (-1,5)
distances between the x values are 1 leg
that is from 7 and -1, a distance of 8 units

distances betweeen the y values are the other leg
that is from 11 to 5
that is 6 units

a²+b²=c²
8²+6²=c²
64+36=c²
100=c²
sqrt both sides
10=c
the distance between them is 10 units

average rate of change is just the slope betwen the points
that is just the slope between (-3,-3) and (-4,-1)

slpe between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)

so slope between (-3,-3) and (-4,-1) is (-1-(-3))/(-4-(-3))=(-1+3)/(-4+3)=2/-1=-2

the average rate of change is -2

How to factor out the greatest common factor in a polynomial?

Answers

Hello,

To find something COMMON, we must at least have 2 things!

So , we can find the greatest common factor of 2 polynomials!

Final answer:

To factor out the GCF in a polynomial, identify the highest common factor, write it outside the parentheses, divide each term by the GCF, and write the quotients inside the parentheses.

Explanation:

To factor out the greatest common factor (GCF) in a polynomial, follow these steps:

First, identify the highest common factor that is present in each term of the polynomial.Write down this factor outside of a set of parentheses.Divide each term of the polynomial by the GCF, and place the resulting quotient inside the parentheses. This step can be seen as dividing both sides by the same factor to turn polynomial terms into integers, if that is easier to understand.Check your answer to see if it simplifies further and whether it is reasonable.

For example, for the polynomial 6x³ + 9x², the GCF is 3x2. Factoring out the GCF gives us:

3x²(2x + 3)

The products inside the parentheses are the result of dividing the original terms by the GCF. Remember, by finding the GCF, we simplify the algebra and may check the work by expanding the factored form back out to verify it equals the original polynomial.

Kite DCFE is inscribed in circle A shown below:



If the measure of arc DEF is 266°, what is the measure of ∠DEF?
Numerical Answers Expected!

Answers

check the pictures below.

the arcDEF is the intercepted arc.

Answer:

133  degrees

Step-by-step explanation:

Given is a picture of a kite DCFE inscribed in circle A

The vertices of the kite D, C, E and F lie on the circle.

A is the centre.

Arc DEF = 266 degrees

This means the subtended angle of arc DEF at the centre = Angle DAF = 266

By theorem on circles, we have central angle of any arc is twice the angle subtended by the arc on the remaining part of the circumference

Hence

Angle DEF = 1/2 angle DAF

i.e. DEF =[tex]\frac{266}{2} =133[/tex]

133 degrees

d=common differnce, or how much each term increases by
n=which term



example

1,3,5, etc
first term is 1
common difference is 2 because it increases by 2 each time
so the formula would be

1. A ladybug lands on the end of a pinwheel that is spinning at a steady speed. The equation y = –7 sin (0.4πx) + 11 gives the height of the ladybug y, in centimeters, above the ground x seconds after landing. What is the diameter of the pinwheel

Answers

That question isn't nearly as hard as they want it to be.  The "a" in the sin function is the altitude of the function...how high it goes up and how low it goes down.  The negative in front of the 7 just means that it starts going down before it goes up (a classic sine wave goes up and then down; the negative just reverses that).  From the wave's midpoint on the y axis, which is 11 (hence, the +11 in the equation), the wave goes up 7 (to a y value of 18) and then goes down 7 (to a y value of 4).  Because it goes up 7 and then down 7, the diameter of the pinwheel is 14. The sin wave mimics the round and round motion of the pinwheel.  You could have been able to tell that it was 14 just by looking at what the altitude was.  The altitude is always the number the wave goes up and down from its midpoint. 7 up and 7 down makes 14 altogether.

Solve the system by the elimination method.
x + y - 6 = 0
x - y - 8 = 0
When you eliminate y , what is the resulting equation?

Answers

Since we have a positive y in one equation and a negative y in the other, we can simple add the two together to eliminate y...

2x-14=0

2x=14

x=7, which makes x+y=6 become:

7+y=6

y=-1, so the solution to the system of equations is the point:

(7, -1)

Answer: 2x = 14

Step-by-step explanation:

Solving the equation us in elimination method,

x + y - 6 = 0...1

x - y - 8 = 0...2

From 1,

x+y = 6...3

x-y = 8...4

To eliminate y, we will add equation 3 and 4 since both the signs attached to y are different.

2x=6+8

2x = 14 (This will be the resulting equation)

To get the variables x, we will divide both sides of the resulting equation by 2

x = 14/2

x = 7

Substituting x = 7 into eqn 3

7 + y = 6

y = -1

How do you solve equations for indicated variables?

ax+r=7
Solving for x?

Answers

You would subtract R from both sides so it would look like

ax=-r+7
then you would divide both sides by A
so then X = A/(-r+7)
and now you can plug in for A and R to solve

The solution is x = (7 - r) / a.

To solve the equation ax + r = 7 for x, follow these steps:

Subtract r from both sides of the equation:

ax + r - r = 7 - r

This simplifies to:

ax = 7 - r

Divide both sides by a:

x = (7 - r) / a

Substitute the value of x back into the original equation to ensure it is correct.

A system of linear equations includes the line that is created by the equation y=0.5x-1 and the line through the points (3, 1) and (–5, –7), shown below.

What is the solution to the system of equations?

a. (–6, –4)
b. (0, –1)
c. (0, –2)
d. (2, 0)

Answers

The answer is (2,0). If you graph the lines, it shows that the intersection occurs right there.

Answer: Solution is,

d. (2, 0)

Step-by-step explanation:

Since, the equation of line that passes through points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

[tex](y-y_1)=\frac{x_2-x_1}{y_2-y_1}(y-y_1)[/tex]

Thus, the equation of line through the points (3, 1) and (–5, –7) is,

[tex](y-1)=\frac{-7-1}{-5-3}(x-3)[/tex]

[tex](y-1)=\frac{-8}{-8}(x-3)[/tex]

[tex]y - 1 = x - 3[/tex]

[tex]\implies y = x - 2------(1)[/tex],

Equation of second line is,

[tex]y = 0.5x - 1 -----(2)[/tex],

By equation (1) and (2),

x - 2 = 0.5x - 1 ⇒ 0.5x = 1 ⇒ x = 2,

From equation (1),

We get, y = 0,

Hence, the solution of line (1) and (2) is (2,0).

Suppose the vertex of a parabola is in the first quadrant and the parabola opens upwards. What can be determined about the value of a and the discriminant?

Answers

A parabola is the graph of a quadratic function, 

that is the graph of [tex]f(x)=a x^{2} +bx+c[/tex], where a is not 0.

from a, b and c we can derive the following informations about the shape of a parabola:

if a>0, the parabola opens upwards.
if a<0, the parabola opens downwards.

Consider the discriminant [tex]D= b^{2} -4ac[/tex]

If D>0, the parabola intersects the x-axis at 2 points.
If D=0, the parabola intersects the x-axis at 1 point.
If D<0, the parabola does not intersect the x axis.

"the vertex of a parabola is in the first quadrant and the parabola opens upwards."

the vertex is in the first quadrant means that the vertex is above the x-axis, and it opens upwards, so the parabola does not intersect the x-axis.

This means that:

Answer: a>0, the discriminant D<0

Final answer:

A parabola in the first quadrant opening upwards implies a positive 'a' value and a discriminant that, if not negative, yields real roots with positive values.

Explanation:

When a parabola has its vertex in the first quadrant and it opens upwards, we can determine specific values for a and the discriminant. The coefficient 'a' in the quadratic equation ax²+bx+c = 0 must be positive for the parabola to open upwards. Concerning the discriminant (calculated as b²-4ac), if the vertex is in the first quadrant, the parabola either does not intersect the x-axis at all (discriminant < 0), or it intersects the x-axis at one point (discriminant = 0) or two points (discriminant > 0) that both have positive x values.

The discriminant plays a key role in determining the nature of the roots of the quadratic equation. For quadratic equations constructed on physical data, they usually have real roots. Practical applications often deem the positive roots significant.

Answers

You complete the square. There is actually a trick to it. If everything is on the same side, you make x^2-10x into (x-5)^2. You divide b/2 and insert that into the perfect square. You then subtract 25 because FOIL tells you that you need to add 25 when in fact you subtract 25 because you are on the same side. 

In final terms, it becomes (x-5)^2+16-25=(x-5)^2-9.

The volume of the empty cone is
V₁ = (1/3) π r²h

The volume of the sphere is
V₂ = (4/3) π r³

Because the melted ice cream completely fills the cone, therefore
V₁ = V₂

A carnival game allows a group of players to each draw and keep a marble from a bag. The bag contains 5 gold marbles, 25 silver marbles, and 70 red marbles.

A player wins a large prize for drawing a gold marble and a small prize for drawing a silver marble. There is no prize for drawing a red marble.

At the start of the game, the probability of winning a large prize is 0.05 and the probability of winning a small prize is 0.25.

1. Suppose that the first player draws a silver marble and wins a small prize. What is the probability that the second player will also win a small prize?

2. If a group of four plays the game one at a time and everyone wins a small prize, which player had the greatest probability of winning a large prize?

3. How could the game be made fair for each player? That is, how could you change the game so that each player has an equal chance of winning a prize?

Answers

5 gold marbles,
25 silver marbles, and
70 red marbles.
------------------------------

100 total marbles

large prize: drawing a gold marble
small prize: drawing a silver marble.

At the start of the game,

probability of winning a large prize = positive outcoumes / total possible outcomes = 5 gold marbles / 100 total marbles =  0.05

probability of winning a small prize = positive outcomes / total possible outcomes = 25 silver marbles / 100 total marbles = 0.25.

1. Suppose that the first player draws a silver marble and wins a small prize. What is the probability that the second player will also win a small prize?

Answer:

numer of silver marbles / number of total marbles = (25 -1 ) / (100 - 1) = 24 / 99 ≈ 0.24

2. If a group of four plays the game one at a time and everyone wins a small prize, which player had the greatest probability of winning a large prize?

Answer:

First player: 0.25

Second player: 5 gold marbles / ( 100 - 1) total marbles = 5 /99 ≈ 0.0505

Third player: 5 gold marbles / (99 - 1) total marbles = 5 / 98 ≈ 0.051

Fourth player: 5 gold marbles / ( 98 - 1) total marbles = 5 / 97 ≈ 0.0515

So, the probability of winning a big prize increases as more balls different of gold marbles are extracted from the bag, and so, in this case, the fourth player has a greater chance to win a large prize.

3. How could the game be made fair for each player? That is, how could you change the game so that each player has an equal chance of winning a prize?

Answer: All the players would have equal chance of winning a prize if the balls were replaced in the bag after each play.
