I do not know if this will satisfy you but

\(e^{i\theta}\quad \text{can be written as }cos\theta+isin\theta\\ so\\ e^{\pi i}=cos\pi +isin\pi = -1+i*0 = -1\)

Find the volume of a grain silo with a half sphere on one end that has the diameter of 6ft and a cylinder height 35 ft.

The radius is a half or the diameter

You have half a sphere with diameter 6'

and you have a cylinder with diameter 6' and length 35'

Volume of sphere is  4/3pi r^3

Volume of cylinder is   pi*r^2*h

Work the 2 out and add them together :)

4 above 3 + 4 above 5

\(\frac{4}{3}+\frac{4}{5}\\ =\frac{4}{3}*\frac{5}{5}+\frac{4}{5}*\frac{3}{3}\\ =\frac{20}{15}+\frac{12}{15}\\ =\frac{32}{15}\\ =2\frac{2}{15}\)

what is an example of a quartic trinomial with a negative leading coefficient and an even constant?

quartic - I looked this up and the different definitions are confusing but most articals seem to imply that is it just a polynomial of degreee 4.    i.e. the highest power is 4.

Trinomial - 3 terms

negative leading coefficient 

even constant - the constant is the number that is not attached to a pronumeral

\(-x^4+5x+8\)

three terms therefore a trinomial

degree 4

8 is an even constant

-1 is a negative leading co-efficient    

inverse sine is the same as   'asin"

eg   asin(0.5) = 30     degrees

use   atan

Some sites say it is the median diabsolute deviation and others say it is the mean absolute deviation.

I would have gone for the mean myself!

This video explains how to find it.

The are on your keyboard above the comma and period.

If you are on a phone they would be in with symbols somewhere.

2+2*2^68-111 = 590295810358705651603

Yes of course!
