B) y=2(x+7)

C) y=2^x +7

D) y= (x+7)^ 2

We will use definition of logarithm.

We know that means .

C)

Step-by-step explanation:

Let be , whose equivalence is determined by algebraic means:

1) Given.

2) Definition of logarithm

3) Definition of logarithm/Result

Hence, the correct answer is C.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
