Easiest way to get the surface area of the lateral square pyramid is by using the formula:

$A_{L} = a \sqrt{ a^{2}+4 h^{2} }$
a = Base edge = 646 ft
h = Height = 350 ft

Using the formula:
$A_{L} = 646 \sqrt{ 646^{2}+4 350^{2} }$
[tex]A_{L} = 6.15335×10^{5} square feet
[tex]A_{L} = 615335<span> square feet</span>

Isabella borrowed $8000 at a rate of 14%, compounded quarterly. Assuming that she makes no payments, how much will she oh after

Cloud [144]

Answer:

$12,088.55

Step-by-step explanation:

The formula for compounded interest is A = P(1+r/n)^n(t)

A= final amount

P = initial amount

r = rate of interest

n = amount of times it is compounded

t = time or amount of years

In this case n=4 because you are compounding quarterly which is 4 times a year and t will be 3 because you are looking for the amount after 3 years. r is .14 because 14% is .14 in decimal form.
