Answer:
Step-by-step explanation:
For this case we are interested on the region shaded on the figure attached.
And we can find the volume with the method of rings.
The area on this case is given by:
![A(x) = \pi [f(x)]^2 = \pi r^2 = \pi [3x]^2 = 9\pi x^2](https://tex.z-dn.net/?f=%20A%28x%29%20%3D%20%5Cpi%20%5Bf%28x%29%5D%5E2%20%3D%20%5Cpi%20r%5E2%20%3D%20%5Cpi%20%5B3x%5D%5E2%20%3D%209%5Cpi%20x%5E2)
And the volume is given by the following formula:

For our case our limits are x=0 and x=2 so we have this:

And if we solve the integral we got this:
![V= \pi [\frac{x^3}{3}]\Big|_0^{2}](https://tex.z-dn.net/?f=%20V%3D%20%5Cpi%20%5B%5Cfrac%7Bx%5E3%7D%7B3%7D%5D%5CBig%7C_0%5E%7B2%7D)
And after evaluate we got this:
![V=\pi [(\frac{8}{3} )-(\frac{0}{3} )]](https://tex.z-dn.net/?f=%20V%3D%5Cpi%20%5B%28%5Cfrac%7B8%7D%7B3%7D%20%29-%28%5Cfrac%7B0%7D%7B3%7D%20%29%5D)
The required equation is
w - 2400 = (3000 - 2400)/(29 - 35) (g - 35)
w - 2400 = -100(g - 35)
w - 2400 = -100g + 3500
w + 100g = 3500 + 2400 = 5900
w + 100g = 5900
Answer:
$37
Step-by-step explanation:
Travis has $8 left in his pocket. Do the opposite of what he did. If he "spent money", add it to the amount he has left. If he "found" money, then subtract.
First, he spent $26 on groceries for dinner. Add 26 with 8:
8 + 26 = 34
He found $1 on the ground. Subtract 1:
34 - 1 = 33
He spent $4 on lunch. Add 4:
33 + 4 = 37
Travis had $37 at the beginning of the day.
