The formula for compound interest is:

I = P(1 +  \frac{r}{n} ) ^{nt}

Where P is the amount you start with, r is the rate, t is the time, and n is the number of times the interest is calculated per year. So for you, this would look like:

I = 20000(1 +  \frac{0.05}{1}) ^{1*7}

Hope it helps!

What’s the equation to convert 100 inches per minute to feet per hour
laiz [17]
Let's look at each part of the equation. We need to first convert the inches to feet then multiply it by 60 to get per hour.
To convert inches to feet, we need to divide by 12.
100÷12
8 1/3
We need to then multiply it by 60 to find per hour.
8 1/3×60= 500
Let's put the equation together, we'll need parenthesis.
( \frac{100}{12} )*60=500

Rewrite each equation in exponential form and evaluate.<br><br> Log5(625)^x=?
Savatey [412]
5^?=625^x, x=1/4

To rewrite in exponential form, the equation would be 5^?=625^x. From here, the bases need to be set equal. Since the fourth root of 625 is 5, the new equation becomes 625^1/4=625^x (625^1/4 is the same as the fourth root of 624). Now that the bases are the same, you can just solve for the variables, which become 1/4=x. Hope this helps :)
