Answer:
Step-by-step explanation:
So what we should do is first expand. What I did was I did it one step at a time, starting with (2x+5)(2x+5). This gave me 
. I then continued to do this, until I got 
. Then you asked me what this would be subtracted from 1. So, what I did was set it so that it would follow this rule, making it
.
After this, I just simplified.
Answer:
100%
Step-by-step explanation:
It is confirmed to happen, or 
The half life of the value of the computer is = 2 years
The time it will take for the computer to be worth 10% of its purchase price= 3.5 years.
<h3>Calculation of the half-life of computer</h3>
V = value of computer= $2000
t = time after original purchase = 1 year
h = half-life of the value of the computer
The half-life value can be calculated using the given formula;
V(t) = 2000(1/2)^t/h
2000×1 = (2000×1/2)^1/h
2000= 1000^1/h
Make h the subject formula,
h= 2000/1000
h = 2 years
The time it will take for the computer to become 10% of its purchase price is,
10/100×2000
= 20000/100
=$200
If after 1 year the computer= $1516
This means that in a year the price of the computer reduces by approximately $500
Therefore it will take approximately 3.5 years to purchase the computer at 10% it's organic price.

Answer:
see below
Step-by-step explanation:
It would take 3 faucets 6/4 = 1.5 minutes to fill a 25-gallon tub since when the number of faucets stays the same, the volume of the tub and the time needed to fill the tub are directly proportional. However, when the volume of the tub stays the same, the number of faucets used and the time needed to fill the tub are <em>inversely</em><em> </em>proportional, therefore, if I double the number of faucets used, it will half the time needed, so the answer is 1.5 / 2 = 0.75 minutes or 45 seconds.
