Suppose Amanda wants to have $800,000 in her IRA at the end of 30 years. She chooses to invest in an annuity that pays

VARVARA [1.3K]

Her IRA interest at the end of 30 years is mathematically given as

Interest= 438,765.56

<h3> IRA interest </h3>

Question Parameters:

N = 30
PV = 0
rate = 5%
FV = 800,000

Generally the equation for the payment function on excel is mathematically given as

A=PMT(rate, nper, pv, [fv], [type])

Therefore, inputting our functions

A=PMT(rate, nper, pv, [fv], [type])

where

A=PMT(5%, 30, 0, [800000], [])

A = 12,041.1481

Hence

interest = 800,000 - 30*12,041.1481

Interest= 438,765.56

What is the slope of the line that goes through -3,7 & -17,3

Natalka [10]

Point 1: (-3, 7)

Point 2: (-17, 3)

To find the slope, we need to use the slope formula which is as follows: m = (y2 - y1) / (x2 - x1). We will plug in each x and y coordinate from our points above, respectively.

m = (3 - 7) / (-17 - - 3)

m = (-4) / (-14)

m = 2/7

The slope of the line that goes through (-3, 7) and (-17, 3) is 2/7.

Hope this helps!! :)
