The area of a circle varies directly with the square of the radius. Since A = πr2, the constant of variation is π. Which of the following examples illustrates direct variation. Identify the constant of variation. A. The circumference of a circle varies directly with the radius. The constant of variation is 2π.
B. The average of 2 numbers varies directly with either number. The constant of variation is the other number.
C. The slope of a line varies directly with the y-intercept. The constant of variation is the slope.
D. The distance between a number and 0 varies directly with the number. The constant of variation is the number.

answer: plz give a pic and answer choices so i can answer!

step-by-step explanation:

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.

step-by-step explanation:

because it just is
