111. Dani has $1,000 in an investment account that earns 3% per year, compounded monthly.

tangare [24]

Answer:

$A(t) = 1000(1.0025)^{12t}$

Step-by-step explanation:

The compound interest formula is given by:

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

Where A(t) is the amount of money in the account after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the number of years the money is invested or borrowed for.

For this problem, we have that:

$P = 1000$

The investment is compounded monthly. There are 12 months in a year. So $n = 12$

The interest rate is 3%. So $r = 0.03$ .

So

The amount of money in her account after t years is:

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

$A(t) = 1000(1 + \frac{0.03}{12})^{12t}$

$A(t) = 1000(1.0025)^{12t}$

Find the vertex of the parabola.

7nadin3 [17]

Answer:

C: (3,1)

Step-by-step explanation:

y = -4x² + 24x - 35

y = -4(x² - 6x) - 35

y = -4[x² - 2(x)(3) + 3² - 3²] - 35

y = -4(x - 3)² -4(-9) - 35

y = -4(x - 3)² + 36 - 35

y = -4(x - 3)² + 1

Vertex (3,1)
