This is an exponential growth/decay problem...
F=Ir^t, F=final value, I=initial value, r=rate, t=time, in this case:
F=I(1.03)^t and they just want to know when F=2I so
2=1.03^t take natural log of both sides...
ln2=t*ln1.03
t=ln2/(ln1.03)
t≈23.45
So it will take approximately 23.45 years for the population to double..
1990+23.45=2013.45
So during the year of 2013 the population will have double from its 1990 level.

Here are some answers
<u>Remember if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)</u>
<u>if leg b is unknown, then. b = √(c² - a²)</u>
<u>for hypotenuse c missing, the formula is. c = √(a² + b²)</u>
Have a wonderful day!
Answer:
let x be the total money so,
3x+5x=32
x=32/8=4
so bridget got,
5×4=£ 20
hope it helps you
Step-by-step explanation:
The like terms are:
12x and 8x - they have the same variables
8, 55, 3, and 180 - they are all regular numbers (if you know what I mean)
