Calculate the shaded area

640

(I hope that I am right)

Step-by-step explanation:

Area of a triange :

30 x 48 = 1440

1440 ÷ 2 = 720

20 x 16 = 320

320 ÷ 2 = 160

Area of a rectangle = Base x Height

20 x 16 = 320

20 - 30 = 10

10 x 16 = 160

160 ÷ 2 = 80

the answer is 8/21

hope this

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.
