The function f(t)= 15,000(0.86)' models the value , in dollars, of a used car t years after it is purchased. What is the value of r for the exponential function

Step-by-step explanation:

The value of r is .86.  That means that each year the car is depreciating 14% from its original price of 15,000

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
