How do you do these types of questions?

V = 11π/30, 'Sketch the region' = Second Attachment, 'Sketch the solid, and a typical dish or washer' = First Attachment

Step-by-step explanation:

Let's start by determining the intersection points of y = x² and x = y². The procedure would be as follows:

x = y²,

x = (x²)² = x⁴,

0 = x⁴ - x,

0 = x(x³ - 1),

x = 0, and x³ - 1 = 0

Solution(s): x = 0, and x = 1

If we want to create a 'three dimensional graph' then we would have to graph the functions y = x² and x = y² between their intersection points at x = 0, and x = 1. Then rotate the region about the line 'y = 1.' Our graph will be as demonstrated in the first attachment.

This cross section is a washer, as it is present with a hole. The top bound of the region is x = y², or y = √x. The bottom bound of the region is y = x². The large radius would be R = 1 - x², and the small radius would be r = 1 - x^1/2. The volume would then be:

As you can see your volume = 11π/30. Your 'two dimensional' graph would just be a sketch of the given function's parabola(s). Take a look at the second attachment for your two dimensional graph.

step-by-step explanation:

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70

.25
