The interest rate r required to increase investment p to amount a in t years is found using the formula r=(a/p)^1-t - 1. Find th
valkas [14]
The interest rate would be 20%.

The formula is derived from the compound interest formula

A=p(1+r)^t.

We want to isolate r in this equation to rewrite the formula.  The first thing we would cancel, outside parentheses, would be p; divide both sides by p and we have

\frac{A}{p}=(1+r)^t

We want to cancel the exponent, t, next.  We can raise a power to its reciprocal to undo it; for example, raising a squared amount to the 1/2 power will undo the exponent.  We will raise both sides of this to the 1/t power:

(\frac{A}{p})^{\frac{1}{t}}=1+r

Now we cancel the 1 by subtracting, giving us

(\frac{A}{p})^{\frac{1}{t}}-1=r

Using this formula, we plug in 3600 for A, 2500 for p and 2 for t:

10.It is 21,000 kilometers around the earth and the earth rotates in 24 hrs. How fast is it  rotating
Drupady [299]
Speed is measured in miles per hour (mph). 

<span>The formula Distance equals rate times time (d=rt) can be rearranged and the rate can be solved, </span>

<span>d = r*t => r = d / t . d = 100 miles, time = 6 hours, Rate = 16.66 mph (16 and two thirds). </span>

<span>The same formula can be used for the second part, </span>

<span>21000 / 24 = rate, Rate = 875 kilometers per hour</span>
