Answer:

Yes

Step-by-step explanation:

Use the completing the square method:

16(x^2-x)+4

=16((x-1/2)^2 - 1/4)+4

=16((x-1/2)^2) - 16/4 + 4

=16(x-1/2)^2

=4^2(x-1/2)^2

You deposit $200 in an account earning 3% interest compounded

anastassius [24]

Answer:

$268.78

Step-by-step explanation:

We will use the compound interest formula to solve this:

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

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 3% into its decimal form:

3% -> $\frac{3}{100}$ -> 0.03

Now, plug in the values:

$A=200(1+\frac{0.03}{1})^{1(10)}$

$A=268.78$

After 10 years, you will have $268.78
