hello I really need help with this quiz. With work shown when indicated. Please se attached
MATH 107 Quiz 1 Name Click here to enter text.
Each question is worth 5 points. Questions 1 – 5 are multiple choice; you do not need to show your work.
Short answers for Questions 6 – 10; show your work to earn full credit – highlight answers in yellow or
draw a box around the answer. You can insert additional lines if needed.
Leave answers in exact form unless otherwise directed to approximate the results. Write all fractions in
lowest form and round decimals to hundredths. Write answers using positive exponents except when using
scientific notation. Simplify all radicals and rationalize the denominators. Write complex numbers in the
form a + bi. Applied problems must have the variables identified and an equation for full credit.
MULTIPLE CHOICE
