What is the total amount for an investment of $1600 invested at 4.25% for 20 years and compounded continuously?
galina1969 [7]

Answer:

  $3743.43

Step-by-step explanation:

The amount is given by the formula ...

  A = Pe^(rt)

where P is the principal, r is the annual rate compounded continuously, and t is the number of years. Filling in the values, we get ...

  A = $1600·e^(0.0425·20) = $1600·e^0.85

  ≈ $1600·2.33964685 ≈ $3743.43

The amount in the account will be $3743.43.

Suppose that x and y vary inversely. write a function that models each inverse variation.
Maurinko [17]

Answer:

y = - \frac{24}{x}

Step-by-step explanation:

Given that the quantities vary inversely then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition x = 4 when y = - 6

k = yx = - 6 × 4 = - 24

y = - \frac{24}{x} ← equation of variation
