Answer:
7.5 hours (7 hours and 30 minutes)
Step-by-step explanation:
ok Let's start with 64km/h.
1.6 km=1 mile,
64÷1.6=40miles
so 64km/h changes into 40miles/hour.
Zebras's round trip =300miles,
300/40=7.5
so answer is 7.5 hours.
Answer: f(3)
Step-by-step explanation:
First find the formula for the rate of change by taking the derivative of 2^x. Let f(x) equal some hypothetical y-value, then take the natural log of both sides.

Implicitly differentiate the left side and take the derivative of the right side

Multiply both sides by 'y' which was defined as 2^x

Plug in x = 2 and x = 3 to see which slope is larger
