Which variable is most important to the following problem?
Dorothy played the first 17 minutes of the hockey game. Evelyn then re
her for the rest of the hall. Evelyn started the second half and was rep
by Dorothy with 21 minutes left in the game. If each half is 45 minutes
how long did Evelyn play during the second half?
O A. the number of minutes Evelyn played in the second half
O B. the length of a half
O C. the number of minutes Dorothy played in the second half

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

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.
