Foil the binomials

First: n*n=n^2
Outer: n*-5=-5n
Inner: -3*n=-3n
Last: -3*-5=15

Put it together and simplify
n^2-5n-3n+15
n^2-8n+15

Final answer: A

An oblique cylinder has a radius of 8 inches and a volume of 1,024 cubic inches. Use Cavalieri’s Principle to calculate the heig
enot [183]
Remark
All Cavaliere's principle says is that a slanted cylinder (for example) has the same volume as a cylinder with perpendicular parallel lines that the cylinder is sitting on.

I little known or maybe not a well emphasized fact is that the base is the same all the way up the cylinder. The coin picture below shows that. The basic formula for a Cavaliere cylinder is the same as for an ordinary cylinder.

See picture below

Formula
V = B * H 

Sub and Solve
V = 1024
r = 8
p=3.14

V = pi*r^2 * h
1024 = 3.14*8^2 * h    combine the right side.
1024 = 3.14*64 *h       
1024 = 200.96 * h       divide by 200.96
1024/200.96 = h
You are only getting 5 inches.

None of your answers work.The conversion to meters is going to give you an even smaller number. If you add a comment, I'll come back and edit this question.

Answer:

y = 3x - 8

Step-by-step explanation:

Line is passing through the points (2, - 2) & (0, - 8)

Slope of line

\: m =  \frac{ - 8 - ( - 2)}{0 - 2}   \\  \\ =  \frac{ - 8 + 2}{ - 2}   \\  \\ =  \frac{ - 6}{ - 2}   \\  \\ = 3 \\ \\y-intercept = b = - 8\\ \\equation \: of \: line \: in  \:slope \:\\ intrecept \:  form \: is \: given \: as \\ \\  y = mx + b \\  \\ y = 3x + ( - 8) \\  \\  \huge \red {y = 3x - 8}
