I think you’re subtracting 5. So now it’s f^-1(x)= 3x+5/2. Not too sure but hope this may help. So, C.

It's C because you change 2/5 into 4/10 then you add 4/10+4/10 which equals 8/10 and is 1 mph. So you add another 2/10 which is an half of a half which equals 1/4. So C

Use the recursive formula f(n) = 0.4 ⋅ f(n − 1) + 12 to determine the 2nd term if f(1) = 4.

Answer:

f(2) = 13.6

Step-by-step explanation:

Using the recursive formula and f(1) = 4 , then

f(2) = 0.4 f(1) + 12 = (0.4) × 4) + 12 = 1.6 + 12 = 13.6

Paul is driving his car. At the end of two hours he has driven 68 miles, then at the end of 4 hours he has driven 132 miles. Wha

This problem describes two points in a route of 4 hours. He went through 68 miles after the first two hours, and 132 miles after 4 hours of driving. We need to calculate the average rate of change.

The average rate of change is the division between the total distance and the time it took to travel that distance, so we have:

$r=\frac{132}{4}=33\text{ miles per hour}$

The average rate of change is equal to 33 miles per hour.
