Final Review Quiz 2
Answer the following questions on looseleaf. Show all work. Each question will be worth 2
points. Questions with no work will receive no credit, “did in calculator” is not sufficient work.
Late papers will not be accepted. Remember if you use more than one piece of paper they must
be stapled together.
1. Find the value of x, to the nearest ten minutes, given cos x  0.4872 .
2. If x  log 3 62 , find the value of x to the nearest hundredth.
3. In which quadrant does the sum of 2  3i , and ,1  5i lie?
4. Reduce the algebraic fraction to lowest terms:
x 2  12 x  36
.
x2  7x  6
5. Find the solution set for the inequality x 2  4 x  32  0 . Remember to graph your answer
on a number line as well as give the algebraic solution.
