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.

Say F (distance) = xt + yThis implies that for every value of the distance, you substitute the value given for time. Generate a simultaneous equation with two unknowns by getting the constants (x and y)Then go back and plug it in the original equation and start the substitution.Similarly for Cost C as a function of the number of apples bought, the same approach will be used to generate the general equation linking the two terms together.

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

I’m having a hard time understanding your question

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
