Answer:

16%

Step-by-step explanation:

Great answer! When you divide the interest by the product of the principal and time, you get 0.16, which when converted to a percent is 16%.

The money you borrow = 25 dollars.
HE charged you 2% interest for 6 months
=> in 12 months = 2% interest
25 dollars * .02 = 0.5 dollars for 6 months.
=> 25 + 0.5 = 25.50 dollars
for 1 year
=> 25 * 0.04 =1 dollar
=> 26 dollars in a year

Answer:

0.25     Converges

Step-by-step explanation:

First, we need to expand our series so that we get the following:

\sum _{n=1}^{\infty \:}\frac{n}{4^n}+\frac{1}{4^{n+1}}

We can then use the series ratio test on each term. (L < 1 = absolutely convergent)

\sum _{n=1}^{\infty \:}\frac{n}{4^n}

\lim_{n \to \infty} \frac{n}{4^{n}\\} =

⇒  converges

\sum _{n=1}^{\infty \:}\frac{1}{4^n^+1}

\lim_{n \to \infty} \frac{n}{4^{n}^+1\\}

⇒  converges

converges + converges

= converges

~Hope this helps! Once again, sorry if my explanation is a bit confusing~

Trapezoid= (base 1+base2)×height÷2
square, rectangle, rhombus, parrellogram, etc= base × height
triangles=base ×height÷2
hope this is what you were looking for if it's not in feet already you need the convert it
