For this case we have that Jim's age is given by variable M.

Let the variable "x" be the age of Jim's daughter. If she is 21 years younger than him, then the value of "x" is given by:

x = M-21

So, Jim's daughter is M-21 years old.

Answer:

Jim's daughter is M-21 years old.

H=3.4s- start with the problem
20=3.4s- substitute the known number(s)
20/3.4=3.4/3.4 s- divide both sides by 3.4
The answer is about 5.88, your answer should be between 5 and 6

Dmitrij [34]

Answer:

V=9\pi\sqrt{3}

Step-by-step explanation:

In order to solve this problem we must start by graphing the given function and finding the differential area we will use to set our integral up. (See attached picture).

The formula we will use for this problem is the following:

V=\int\limits^b_a {\pi r^{2}} \, dy

where:

r=6-(6-3 sec(y))

r=3 sec(y)

a=0

b=\frac{\pi}{3}

so the volume becomes:

V=\int\limits^\frac{\pi}{3}_0 {\pi (3 sec(y))^{2}} \, dy

This can be simplified to:

V=\int\limits^\frac{\pi}{3}_0 {9\pi sec^{2}(y)} \, dy

and the integral can be rewritten like this:

V=9\pi\int\limits^\frac{\pi}{3}_0 {sec^{2}(y)} \, dy

which is a standard integral so we solve it to:

V=9\pi[tan y]\limits^\frac{\pi}{3}_0

so we get:

V=9\pi[tan \frac{\pi}{3} - tan 0]

which yields:

V=9\pi\sqrt{3}]
