Corey is trying to calculate the price of his groceries in his head. He has 4 apples for 35 cents each, 5 potatoes for 15 cents each, and 3 cake mixes for $2.25 each. He begins by thinking to himself: "let’s see, 4 times 34 cents is what

The correct answer is $8.90.

Step-by-step explanation:

Corey has bought some groceries.

Amount Corey spent on 4 apples costing 35 cents each is 35 × 4 = 140 cents = $1.4

Amount Corey spent on 5 potatoes costing 15 cents each is 15 × 5 = 75 cents = $0.75

Amount Corey spent on 3 cake mixes costing $2.25 each is 2.25 × 3 = $6.75.

Total amount spent by Corey to buy groceries is $ (6.75 + 0.75 + 1.4) = $ 8.90.

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.
