An investment of \displaystyle PP dollars is compounded \displaystyle nn-times per year at a constant annual interest rate of \displaystyle r\%r%. The amount of money \displaystyle A(t)A(t) that you have after investing for \displaystyle tt years is given by the equation A(t) = P\left(1+\frac{r}{n}\right)^{nt}. A(t)=P(1+

How much money would you have after 18 years if you invested $15,000 at an annual interest rate of 4% where the interest is compounded monthly? Round to the nearest dollar.

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
