To solve the problem shown in the figure attached, you must apply the proccedure shown below:

 1. You have that the equation for calculate the area of a circle is:

 A=πr²

 2. You have that the formula for calculate the diameter of a circle is:

 d=2r

 Therefore, the radius is r=d/2

 where r is the radius of the circle

 3. Keeping the information above on mind, you have the correct sequence of the equations by clearing the diameter d, is shown below:

 A=π(d/2)²
 A=πd²/4
 4A=πd²
 d²=4A/π
 d√(4A/π)

 Therefore, as you can see, the answer is:

 A=π(d/2)²
 A=πd²/4
 4A=πd²
 d²=4A/π
 d√(4A/π)

How do you do 720 divided by 10 with the exponet of 3
Allisa [31]
If you mean 720/10^3, you do 10*10*10. This equals 1000. Now, do 720/1000. This is 0.72, or 72/100, which is your answer.

How many dimensions does a line segment have​
Natalija [7]

Answer:

A line segment has one dimensions.

Step-by-step explanation:

A line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints.

Dimension is an aspect or feature of an object.

A line segment, let us say AB has two endpoints and has only one measurable feature that is its length which is actually the distance between the two end points A and B.

Hence, a line segment is one-dimensional.

Angie and Kenny play online video games. Angie buys 1 software package and 3 months of game play. Kenny buys 1 software package
andrey2020 [161]

Answer:The cost of one month of game-play =$20


Step-by-step explanation:

Let the cost of one month of gameplay be x

Then cost of game-play bought by Angie =3x.....(1)

and Then cost of game-play bought by Kenny=4x......(2)

Cost of each software package =$50......(3)

The the total cost =240= sum of costs of software bought by both of them and game-play)=50+50+3x+4x

⇒240=100+7x.......→(by adding like terms)

⇒140=7x⇒x=20.....→( dividing both sides by 7 )

∴the cost of one month of game-play =$20

PLZ HELP WILL MARK BRAINLIEST
Fantom [35]

Answer:

  g(x) = (1/6)(x +7)^2 -8

Step-by-step explanation:

The transformation ...

  g(x) = a·f(x -h) +k

represents vertical scaling by a factor of 'a', right shift by h units, and up shift by k units. You want the function g(x) for f(x) = x^2, a = 1/6, h = -7, and k = -8. Those transformations give you ...

  g(x) = (1/6)(x +7)^2 -8

Find the angles between -pi and pi that satisfy:<br><br> (−√3) sin(v)+cos(v)=√3
MAXImum [283]

Observe that

\sin\left(\dfrac\pi6-v\right)=\sin\dfrac\pi6\cos v-\cos\dfrac\pi6\sin v=\dfrac12\cos v-\dfrac{\sqrt3}2\sin v

In the original equation, divide both sides by \dfrac12:

-\sqrt3\sin v+\cos v=\sqrt3\implies\dfrac12\cos v-\dfrac{\sqrt3}2\sin v=\dfrac{\sqrt3}2

\implies\sin\left(\dfrac\pi6-v\right)=\dfrac{\sqrt3}2

Next,

\sin x=\dfrac{\sqrt3}2\implies x=\dfrac\pi3+2n\pi,x=\dfrac{2\pi}3+2n\pi

where n is any integer. Then

\sin\left(\dfrac\pi6-v\right)\implies v=-\dfrac\pi6-2n\pi,v=-\dfrac\pi2-2n\pi

Fix n=0 to ensure -\pi, so that

v=-\dfrac\pi6,v=-\dfrac\pi2
