A = $ 17,000 e^0.03(4)

What is A to the nearest cent?

A = $19.167.45

Step-by-step explanation:

The continuous compound  interest formula,  is used when interest is compounded continuously; that is, when the number of compounding periods per year increases without bound.  

Using the continuous compound interest formula,   where:

A = amount in the end of t period

P = principal = $17,000

r = interest rate = 0.03 or 3%

t = time = 4

Substitute these values into the formula:

A = $19.167.45

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
