Answer:

64k^2 - 16k +1

Step-by-step explanation:

We can rewrite this as

(-8k+1) ^2

We know that (a+b)^2 = a^2 +2ab +b^2

Let a = -8k and b = 1

(-8k+1) = (-8k)^2 +2*(-8k)(1) + 1^2

=64k^2 - 16k +1

Is 6x 2/8 the same as 6 x 1/8?

Pachacha [2.7K]

No
6× $\frac{2}{8}$ = $\frac{3}{2}$ or 1.5
More: 6× $\frac{1}{4}$ =3× $\frac{1}{2}$ = $\frac{3}{2}$
6× $\frac{1}{8}$ = $\frac{x3}{4}$ or 0.75
More: 3× $\frac{1}{4}$ = $\frac{3}{4}$
Both are different.

find the compound interest earned. round to the nearest cent. $600 at 5% compounded quarterly for 1 1/2 years

stepladder [879]

Answer:

$46.43

Step-by-step explanation:

First, let's use the compound amount equation,

A = P(1+r/n)^(nt), where P is the principal, r is the annual interest rate as a decimal fraction, n is the # of compounding periods per year, and t is the number of years.

Here,

A = $600(1 + 0.05/4)^(4*[1 1/2]). Let's evaluate this:

A = $600*(1.0125)^6

= $646.43.

This is the amount due after 1.5 years if $600 were the original principal borrowed.

If you want ONLY the compound interest, subtract $600 from $646.43:

Compound interest was $46.43.
