suppose you deposit $1000 in a savings account that pays 4.8% interest compounded monthly. Write an exponential function to mode
zubka84 [21]

Answer:

The exponential function is A(t) = 1000(1.004)^{12t}.

You will have $1,100.55 in the account after 2 years.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

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

Where A(t) is the amount of money 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 year and t is the time in years for which the money is invested or borrowed.

Deposit $1000 in a savings account that pays 4.8% interest compounded monthly.

This means that P = 1000, r = 0.048, n = 12. So

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

A(t) = 1000(1 + \frac{0.048}{12})^{12t}

A(t) = 1000(1 + 0.004)^{12t}

A(t) = 1000(1.004)^{12t}

This is the exponential function

How much will you have in your account after 2 years?

This is A(2). So

A(2) = 1000(1.004)^{24} = 1100.55

You will have $1,100.55 in the account after 2 years.

Oil leaked from a tank at a rate of r(t) liters per hour. the rate decreased as time passed, and values of the rate at two hour
Galina-37 [17]
The given data is
t, h:            0     2     4     6     8   10
r(t), L/h:   8.6  7.9  6.8  6.4  5.7  5.3

The lower and upper estimates for the total amount that leaked may be computed as the Left and Right Riemann sums.

The shape of the graph of r versus will determine which of the two sums yields an upper or lower sum.
The plot of the graph is shown below.

The Left Riemann sum is
Sl = 2*(8.6+7.9+6.8+6.4+5.7) = 70.8 L

The Right Riemann sum is
Sr = 2*(7.9+6.8+6.4+5.7+5.3) = 64.2 L

Answer:
The lower estimate for oil leakage is 64.2 L
The upper estimate for oil leakage is 70.8 L
