(d) A student plans to drive from state A to state B. The speed limit is 65 mph in state A and 60 mph in state B. The trip involves 229.4 miles of travel in state A followed by 219.5 miles in state B. If the student drives at the posted speed limits, estimate the driving time.
If the student drives at the posted speed limits, the driving time from state A to state Bis
(Do not round until the final answer. Then round to two decimal places as needed.)
hours.

i think the answer is b)

step-by-step explanation:

answer: i guess 5 units?

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.

the answer is d

hope this
