Given two points, (x1, y1) and (x2, y2), the slope can be found by ...

... slope = (change in y)/(change in x) = (y2-y1)/(x2-x1)

For your given points, the slope is

... slope = (79 -(-20))/(9 -(-2)) = 99/11 = 9

The point-slope equation for a line with slope m through point (h, k) is

... y -k = m(x -h)

You have m=9, h=-2, k=-20, so the equation is

... y +2 = 9(x +20)

A painter needs to paint the bottom of a circular pool. The pool has a radius of 30 feet. A store sells 5-gallon cans of paint.

DIA [1.3K]

Answer:

Step-by-step explanation:

the area of the radius 30 is 2827 and since 1 bucket can cover 1800 we will only need 2 buckets because we need a total of 2827 and 1 bucket covers 1800 so 2 buckets will cover 3600.

Find the future value of an annuity due of $400 each quarter for 4 1 2 years at 13%, compounded quarterly. (Round your answer to

Flura [38]

Answer:

$9891.23

Step-by-step explanation:

The formula for future value of annuity due is:

$FV=P[\frac{(1+r)^{n}-1}{r}]*(1+r)$

Where,

FV is the future value of the annuity (what we need to find)
P is the periodic payment (here it is $400)
r is the interest rate per period (here 13% yearly interest is actually $\frac{13}{4}=3.25$ percent per period(quarter))
n is the number of periods (here the annuity is for $4\frac{1}{2}$ years, which is $4\frac{1}{2}*4=18$ periods, since quarterly and there are 4 quarters in 1 year)
