PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! SUPER IMPORTANT QUESTION!!!

Answer:

Distance between two cities is 193.94 miles.

Step-by-step explanation:

We have,

Madison and Wisconsin have latitudes 43.0731°N and 45.9172°N respectively.

Thus, their difference is 45.9172°N - 43.0731°N = 2.8441°

We assumed, the diameter of earth is 7917.5 miles.

So, the radius = $\frac{7917.5}{2}$ = 3958.75 miles

So, using the cosine formula, we have,

$a^{2}=b^{2}+c^{2}-2bc\cos A$

i.e. $a^{2}=3958.75^{2}+3958.75^{2}-2\times 3958.75\times \cos 2.8441$

i.e. $a^{2}=31343403.13\times 0.0012$

i.e. $a^{2}=37612.08$

i.e. a= 193.94 miles.

Hence, the distance between two cities is 193.94 miles.

3. What amount of money is necessary to be invested at 5% simple interest to yield $320 in interest after 4 years?

Simora [160]

Answer:

$Amount = \$1920$

Step-by-step explanation:

Given

$Interest =\$320$

$Rate = 5\%$

$Years = 4$

Required

Determine the invested amount

First, we need to determine the Principal

This is calculated as:

$Interest = Principal * Rate * Time$

Solve for Principal

$Principal = \frac{Interest}{Rate * Time}$

$Principal = \frac{\$320}{0.05 * 4}$

$Principal = \frac{\$320}{0.2}$

$Principal = \$1600$

Add the principal to the interest

$Amount = Principal + Interest$

$Amount = \$1600 + \$320$

$Amount = \$1920$
