The range of y=-2.02+4+8 is 9.98 hope this helps:)!
Answer:
The cost function is
.
Step-by-step explanation:
It is given that the marginal cost of manufacturing an item when x thousand items are produced is

We need to find the cost function.
Multiply both sides by dx.

Integrate both sides to find the cost function.



where, C(x) is const function and C is a constant.

It is given that C(0)=550. Substitute x=0 in the above function.



Therefore, the cost function is
.
9- -3=12
2-2=0.
Slope is 12/0
Answer = 5 problems per minute
Because you do the number of problems divided by the minutes eg 35/7 = 5
Answer:
x=9
Step-by-step explanation:
The goal is to combine our knowledge of geometry area and algebra skills to solve this problems.
We know area of rectangle is

where l is the length and w is the width. We know that one side is 3 less than the other side. We can use L or W but let use L. Let x replace L
One side is x, while the other side is

Both multiply to 54.





or

Distance. is positive so x=9
