Answer:
$13,756.31
Step-by-step explanation:
The computation of the amount at the end of the five years is shown below:
Here we applied the FV formula
Given that
NPER = 5 × 52 = 260
RATE = 2.25% ÷ 52 = 0.043269%
PV = $0
PMT = $50
The formula is given below:
=-FV(RATE;NPER;PMT;PV;TYPE)
After applying the above formula, the future value is $13,756.31
9514 1404 393
Answer:
(b) -1
Step-by-step explanation:
The graph shows the difference between the two expressions is zero at x=-1.

<em>Additional comment</em>
For finding solutions to polynomial equations, I like to put them in the form f(x)=0. Most graphing calculators find zeros (x-intercepts) easily. Sometimes they don't do so well with points where curves intersect. Also, the function f(x) is easily iterated by most graphing calculators in those situations where the root is irrational or needs to be found to best possible accuracy.
