Answer:

n=-296

Steps to Equation:

the perpendicular slope to -15 is 1/15
plug what you have into y2-y1/x2-x1
8 – -12/4-n
simplify so 20/4-n
then 20/4-n = 1/15
multiple 1 by 4-n and 15 by 20
4-n=300
subtract 4 by both sides
-n=296
divide by negative 1 on both sides
n= -296

What fomula can be used to describe the sequence? -2/3,-4,-24,-144

Lunna [17]

This is a geometric sequence with n th term formula

$a_{n}$ = $a_{1}$ $(r)^{n-1}$

where r is the common ratio and $a_{1}$ the first term

here $a_{1}$ = - $\frac{2}{3}$ and

r = $\frac{-144}{-24}$ = $\frac{-24}{-4}$ = 6

$a_{n}$ = - $\frac{2}{3}$ $(6)^{n-1}$

or in terms of x

f(x) = - $\frac{2}{3}$ $(6)^{x-1}$

A 9 cm tall cone shaped paper cup can hold up to 58.9 cm cubed of water. What is the minimum amount of paper needed to make the

babymother [125]

Volume of a cone, V = πr^2h/3

r = Sqrt 3V/πh = Sqrt [(58.9*3)/(3.14*9)] = 2.5 cm, minimum

Surface area, A = πr [r+ Sqrt (h^2+r^2)] = 3.14*2.5*[2.5+ Sqrt (9^2+2.5^2)] = 92.95 cm^2

Therefore, minimum amount of paper required is 92.95 cm^2
