The Formula for the compound interest is:

A = Amount Accumulated = $5000
P = Principal Amount = $1250
n = compound period in a year = 4
r = Interest Rate
t = Time in years = 12
Using the values in the formula, we get:

Thus, in order to achieve the given conditions, 11.72% interest rate is required.
<em>A</em><em>nswer</em> : 6 keychains
Step-by-step explanation:
there are 12 inches in 1 feet
so,there 36 inches of string
Mia needs 6 inches for each keychain.
36/6 is 6.
so in total there's 6 keychains being made
Answer:
f(x)=4x^2 and g(x)=-8x^2 + 4x - 4
(f+g)(x) = -8x^2 + 4x - 4 + 4x^2 = -4x^2 + 4x - 4 = -4(x^2 -x + 1)
(f+g)(-3) = -4( -3^2 -(-3) + 1) = -4 x 13 = -52
Hope this helps!

Answer:

Step-by-step explanation:
Let's consider the following expression.

We will use the Product of Powers Property. This property states that to multiply powers having the same base, we have to add the exponents.

The simplified expression is
