7,300 deposit earning 3.3% compounded monthly after 1 year. What will the balance after 1 year will be?

$7,544.58

Step-by-step explanation:

We will use the compound interest formula provided to solve this:

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 3.3% into its decimal form:

3.3% -> -> 0.033

Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:

The balance after 1 year will be $7,544.58

answer: a

step-by-step explanation:

10.2 units

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
