Answer:
1020?
Step-by-step explanation:
im not sure completely but the formula for volume is length x width x height
Is this suppose to be a question if so give me more information. But 9+9=18
Answer:
120 m
Step-by-step explanation:
To find the volume of the prism on the bottom, multiply length times height times width
3x3x12=108
next is the pyramid on top.
Formula is V=bh x 1/2
8, the height, times 3, the base, = 24
24x 1/2 or 24/2 = 12
108+12= 120
120 m
Answer:
![3 + \frac{1}{2\sqrt{3} } + \frac{1}{5\sqrt[5]{81} }](https://tex.z-dn.net/?f=3%20%2B%20%5Cfrac%7B1%7D%7B2%5Csqrt%7B3%7D%20%7D%20%2B%20%5Cfrac%7B1%7D%7B5%5Csqrt%5B5%5D%7B81%7D%20%7D)
Step-by-step explanation:
Just to make it easier to see, 
and ![\sqrt[5]{x} = x^{\frac{1}{5} }](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%7D%20%3D%20x%5E%7B%5Cfrac%7B1%7D%7B5%7D%20%7D)
This way we could more easily use the power rule of derivatives.
So if f(x) = 
then f'(x) will be as follows.
f'(x) = ![x^{1} +\frac{1}{2} x^{-\frac{1}{2} } +\frac{1}{5} x^{-\frac{4}{5} } = x +\frac{1}{2x^{\frac{1}{2} }} +\frac{1}{ 5x^{\frac{4}{5} }} = x +\frac{1}{2\sqrt{x}} +\frac{1}{ 5\sqrt[5]{x^4} }](https://tex.z-dn.net/?f=x%5E%7B1%7D%20%2B%5Cfrac%7B1%7D%7B2%7D%20x%5E%7B-%5Cfrac%7B1%7D%7B2%7D%20%7D%20%2B%5Cfrac%7B1%7D%7B5%7D%20x%5E%7B-%5Cfrac%7B4%7D%7B5%7D%20%7D%20%3D%20x%20%2B%5Cfrac%7B1%7D%7B2x%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%7D%20%2B%5Cfrac%7B1%7D%7B%205x%5E%7B%5Cfrac%7B4%7D%7B5%7D%20%7D%7D%20%3D%20x%20%2B%5Cfrac%7B1%7D%7B2%5Csqrt%7Bx%7D%7D%20%2B%5Cfrac%7B1%7D%7B%205%5Csqrt%5B5%5D%7Bx%5E4%7D%20%7D)
to find f'(3) just plug 3 into f'(x) so
