The function f(t) = 15,000(0.86)t 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?

grab rope, tie a loop-de-loop, put it around ur neck, now jump while its tied to a high place. now your shoes are cool.

step-by-step explanation:

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
