Compound Interest Formula:
A = P(1 + r/n)^(nt)

A= Accumulated amount with interest P= principal= $1000
R= annual interest rate (decimal)= 0.05
N= # times compounded per year= 12
T= # of years= 10

A= 1000(1 + 0.05/12)^(12*10)
divide inside parentheses first

A= 1000(1 + 0.0041666667)^ (12*10)
add inside parentheses

A= 1000(1.0041666667)^ (12*10)
multiply exponents

A= 1000(1.0041666667)^120
multiply parentheses by exponents

A= 1000(1.6470095043)
multiply last two numbers

A= $1,647.01 amount after 10 years

ANSWER:
D) $1647.01 total after 10 years

Hope this helps! :)

What is the solution of x=2+ square root x-2?

alex41 [277]

So I'm going to assume that this question is asking for non extraneous solutions, or solutions that are found in the equation and are valid solutions when plugged back into the equation. So firstly, subtract 2 on both sides of the equation:

$x-2=\sqrt{x-2}$

Next, square both sides:

$(x-2)^2=x-2\\(x-2)(x-2)=x-2\\x^2-4x+4=x-2$

Next, subtract x and add 2 to both sides of the equation:

$x^2-5x+6=0$

Now we are going to be factoring by grouping to find the solution(s). Firstly, what two terms have a product of 6x^2 and a sum of -5x? That would be -3x and -2x. Replace -5x with -2x - 3x:

$x^2-2x-3x+6=0$
