miss Akunina [59]

20100 = 16000 * (1.02)^ t

20100/16000 = 1.02^t

1.25625 = 1.02^t

log 1.25625 = t * log 1.02

t = log 1.25625 / log 1.02
= 11.5

Evaluate C= 2 A r, for r= 8.<br>C=10,<br>C = 16<br>C= 28.7<br>C= 16

USPshnik [31]

Answer: Second Option

$C = 16\pi$

Step-by-step explanation:

We are evaluating aarco lengths

The formula for the arc length is:

$C = 2\pi r$

We want to know what is the arc length for a radius of r = 8

Then we substitute r = 8 in the equation and solve

$C = 2 \pi * 8$

$C = 16\pi$

The correct answer is the second option

The fraction $\frac{3}{5}$ and $\frac{2}{3}$ are the greatest in each combination.

Explanation:

Comparing the fraction $\frac{1}{2}$ with $\frac{1}{3}$ and $\frac{3}{5}$ to find the greatest value.

The fraction $\frac{1}{2}>\frac{1}{3}$ and $\frac{1}{2}$

Thus, $\frac{1}{3}$

Hence, $\frac{3}{5}$ is the greatest value in this combination.

Also, Comparing the fraction $\frac{1}{2}$ with $\frac{3}{7}$ and $\frac{2}{3}$ to find the greatest value.

The fraction $\frac{1}{2}>\frac{3}{7}$ and $\frac{1}{2}$

Thus, $\frac{3}{7}$

Hence, $\frac{2}{3}$ is the greatest value in this combination.
