Answer: Surface area is 169π
Step-by-step explanation:




C.
6 is a constant, so we know that y is greater than or equal to 6.
x is just a variable, but it has to be positive, so it could be anything greater than or equal to 0.
Total flour = white flour + wheat flour, therefore y = x + 6.
Answer:
Slope
Step-by-step explanation:
slope is the ratio of the vertical and horizontal changes between two points on a surface or a line
Given:
The revenue function is

The cost function is

To find:
The profit function.
Solution:
We know that, the total profit P is defined as total revenue R minus total cost C.
So, the profit function is




Therefore, the profit function is
.
Domain is the x values you can use
range is the y values
a.
the domain
hmm, seems to be all real numbers except for at x=0, it gets really close tho
so D=(-∞,0)U(0,∞)
range is all real numbers except for y=0, it gets really close tho
R=(-∞,0)U(0,∞)
b.
domain
that empty circle means something like < or >
goes from 5 to 6, not including 5
so domain is D=(5,6]
range is from -4 to 2, not including -4
range is R=(-4,2]
