The equation for compound interest is:

Where r is the interest rate and n is the number of times per year it's applied.
Annually n = 1 and 7% interest r = 0.07
The quarterly rate 2% is already quartered 0.02 = r/n .

You can see that Alexander is incorrect. A quarterly compound interest rate of 2% will accrue more interest than a 7% compound annual interest rate.
![ (1+0.07) = (1+ r) ^{4} \\ \\ 1.07 = (1+r) ^{4} \\ \\ \sqrt[4]{1.07} = r \\ \\ \sqrt[4]{1.07} - 1 = r \\ \\ r = 0.017](https://tex.z-dn.net/?f=%0A%281%2B0.07%29%20%3D%20%281%2B%20r%29%20%5E%7B4%7D%20%5C%5C%20%5C%5C%201.07%20%3D%20%281%2Br%29%20%5E%7B4%7D%20%5C%5C%20%5C%5C%20%5Csqrt%5B4%5D%7B1.07%7D%20%3D%20r%20%5C%5C%20%5C%5C%20%5Csqrt%5B4%5D%7B1.07%7D%20-%201%20%3D%20r%20%5C%5C%20%5C%5C%20r%20%3D%200.017%20)
1.7% compound quarterly
3 + 1= 4, 4 X 4= 16, so its 4 for the number
Answer: 5 faces,8 edges,5 vertices
Step-by-step explanation:5 faces - of which 1 is a square face at the base and 4 isosceles triangle, above.
5 vertices - of which 4 are at the base where 3 edges meet and one above where 4 edges meet.
8 edges - of which 4 are equal in length and at the base and the other 4 are equal in length and above.

Answer:
When diving in the ocean, you must consider how much pressure you will experience from diving a certain depth.
From the atmosphere, we experience about 14.7 pounds per square inch (psi) and for every foot we dive down into the ocean, we experience another 0.44 psi in pressure.
How far (in feet) can you dive without experiencing more than 58.7 psi of pressure on your body?
:
let d = the depth which gives 58.7 psi
.44d + 14.7 = 58.7
.44d = 58.7 - 14.7
.44d = 44
d = 44/.44
d = 100 ft
