Answer:
Step-by-step explanation:
10- -2 which gives you 12 cause the negatives make a positive.
-9 -0= -9
12 over -9 which simplifies to 4 over -3
Answer:
The shop can cut the cost of production per sandwich to $3.75. The revenue function would then be defined as R(x)=9x.
Step-by-step explanation:
We want to make as big profit as possible by making as little sandwiches as possible. This means that we want the profit, which is 
to be as big as possible.
For the first choice the profit per sandwich is 
dollars.
For the second choice the profit per sandwich is 
dollars.
For the third choice the profit per sandwich is 
dollars.
We see here that for the second choice the profit is greatest, therefore this choice is most suitably correct.
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.
