7. Suppose you earn $15 for each car you wash. Which function describes the relationship
Arturiano [62]

Answer:

E(c) = 15c

Step-by-step explanation:

If I earn $15 for each car i wash and my total earnings are E then we have to form a function which describes this relationship.

My earning for one car wash = $15

Similarly my earnings for c car washes = $15×c

This total earning is equal to E so function representing the equation will be E(c) = 15c

Answer is E(c) = 15c which describes the relashionship of my earnings to the number of cars i wash.

dsp73

Answer:

The units of measurement for the composite function c(w(h)) is canvases over weeks.

Step-by-step explanation:

Given :

The function c(t) approximates how many canvases she paints per hour.

The function w(h) represents how many hours per week Christina spends painting the canvases.

To Find: What are the units of measurement for the composite function c(w(h))?

Solution:

C(t)= canvases paints per hour

W(h)=hours per week

C(w(h)) =canvases paints per hour * hours per week

C(w(h)) =canvases per week

So, Option 3 is true

Hence , the units of measurement for the composite function c(w(h)) is canvases over weeks.
