First and last terms of the given equation are perfect squares. They can be written as

(4p^2)^2+ 2.(4p^2).5+(5)^2
It's like identity 1: (a+b)^2=a^2+2ab+b^2
So a=4p^2 and b=5
Therefore it is equal to (4p^2+5)^2

Amy makes an initial investment of $5000. The investment loses 13.5% each year. Find the amount Amy has at the end of 8 years.

Pani-rosa [81]

Answer:

$\$1,567.11$

Step-by-step explanation:

we know that

The equation of a exponential decay function is given by

$y=a(1-r)^x$

where

y is the value of the investment

x is the number of years

a is the initial value

r is the rate of change

we have

$a=\$5,000\\r=13.5\%=13.5/100=0.135$

substitute

$y=5,000(1-0.135)^x$

$y=5,000(0.865)^x$

Find the amount Amy has at the end of 8 years

For x=8 years

substitute the value of x

$y=5,000(0.865)^8=\$1,567.11$

Im not sure if you need the work, but the answer is 3.8 hours. you make them into fractions, like in one hour ann could build 1/5 of the model car and sam 1/15 of the car. you use that to then find 1/x (how much they could build together) and multiply by the lcd. Its complicated sorry i cant explain well lol
