What is the dependent variable?

1 answer:

6 0

Dear Foxqueen, the dependent variable is D because the grades depend on the time spent playing video games. A is not logical because the video games owned might not be played, B is illogical because the points are the product of the video games, and C is not logical because that is actually the independent variable.

A principal of $3600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 6 years?

zaharov [31]

After 6 years the investment is $5555.88

Step-by-step explanation:

A principal of $3600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 6 years?

The formula used to find future value is:

$A(t)=P(1+\frac{r}{n})^{nt}$

where A(t) = Accumulated amount

P = Principal Amount

r = annual rate

t= time

n= compounding periods per year

We are given:

P = $3600

r = 7.5 %

t = 6

n = 1

Putting values in formula:

$A(t)=P(1+\frac{r}{n})^{nt}\\A(t)=3600(1+\frac{0.075}{1})^{6*1}\\A(t)=3600(\frac{1.075}{1})^6\\A(t)=3600(1.075)^6\\A(t)=3600(1.543)\\A(t)=5555.88$

So, After 6 years the investment is $5555.88

What is the slope of the line?

Vesnalui [34]

It's a flat horizontal line so the slope is 0

Slope = rise/run = 0/run = 0

The "run" can be any number you want as long as it's not 0.
