How much would $100 invested at 8% intrest compounded annually be worth after 15 years? round your answer to the nearest cent. d
frosja888 [35]
Our P = 100, r = .08, n = 1 (annually means once a year), and t = 15.  Filling in accordingly, we have A(t)=100(1+ \frac{.08}{1})^{(1)(15)}.  Simplifying a bit gives us  A(t)=100(1+.08)^{15}  and  A(t)=100(1.08)^{15}.  Raising that number inside the parenthesis to the 15th power gives us  A(t)=100(3.172169114).  Multiplying to finish means that A(t) = $317.22

Which of the following points lie in the solution set to the following system of inequalities? y ≤ x − 5 y ≥ −x − 4
Strike441 [17]
Y ≤ x - 5
y ≥-x - 4

   x - 5 = -x - 4
+ x       + x
 2x - 5 = -4
     + 5  + 5
       2x = 1
        2     2
         x = ¹/₂
         y = x - 5
         y = ¹/₂ - 5
         y = -4¹/₂

The following points that lie in the solution set to the following system of inequalities is (¹/₂, -4¹/₂).
