Find the limits of integration for calculating the volume of the solid, Q, enclosed by the graphs of y = x2 , z = 0, and y + z = 2.

I'm not confident in my results could someone show me how this is done?

An acid solution is 0.110 M in HCl and 0.210 M in H2SO4.

Can you show me how to work the problem? Thank you!

When you dilute a solution, the number of moles of solute doesn't change since you're only adding water . Since n = MV, you can use M1V1 = M2V2 to find V1

(18.0 M)(V1) = (0.195 M)(2 L)

V1 = 0.02167 L or 21.67 mL

Curve y = x² and line y = 4 intersect at (-2, 4) and (2, 4)
So we integrate from x = -2 to x = 2

On this interval, line is above the curve

Each cross section perpendicular to x-axis is shaped like a washer, with
outer radius: R = 4
inner radius: r = x²

We user washer method:

V = p ??2² (R² - r²) dx
V = p ??2² (16 - x4) dx
V = p (16x - x5/5) |?2²
V = p ((32 - 32/5) - (-32 + 32/5))
V = p (64 - 64/5)
V = 256p/5

v = 1/3(15)(8)
= 1/3(120)
= 39.999996
= 40

* pay attention to the order of operations.
