Mathematical models are helpful. Advantages include helping you see the data clearer and helping you visualize. Disadvantages are: time consuming, and if you make a mistake on the graph, its going to hit the entre thing.
Answer:
Points of intersection: (1.225,-1.58) and (1.225,1.58)
Step-by-step explanation:
Given
Required
The region area
Plot the graphs of and
Make y the subject in both equations
Square both sides
Rewrite
Take square roots
So, we have:
Take square roots
So, we have:
The point of intersection is:
Square both sides
Collect like terms
Divide by 2
Take square roots
So, the point of intersection is at: (1.225,-1.58) and (1.225,1.58)

From the attached image, we can see that the curves do not enclose
Hence:
7 percent of 118.26 is 8.28 so then you add that to the total of 118.26 which means the final cost would be $126.54
1. 5, 19, 24, 46, 77, then 98
2. -62, -47, -11, 38, then 56
