Punction gives the distance of a dog
from a post, in feet, as a function of time,
in seconds, since its owner left.
find the value of $(20) and of f(140).
distance from post in feet
20
40
60
80
100 120 140
function c gives the cost, in dollars, of buying n apples. what does each expression
or equation represent in this situation?
a. 8) = 4.50
b. c(2)

The question is not detailed enough as the expression of the distance as a function of time is missing.

Step-by-step explanation:

But we can still assume an expression for the distance as a function of the time in seconds.

a) 8) = 4.50 implies the time in seconds as against the distance of the dog from the post.

b) C(2) - This expression represents the cost of two apples, ere the number of apples is known

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
