• 0

• 1

• 2

• 3

Answer explanation

How many turning points can a cubic function have?

• 2

• 1

What is the measure of the minor arc formed by the hands of a clock at 3:00?

Which of the following equations describe a circle on the coordinate plane with a center at (-2, 5) and diameter of 6 units?

• 4mm

• 3mm

• 2mm

• 1mm

In ʘD, AR is a diameter and 𝑚∠𝐴RC = 40°, what is the measure of ∠CAR?

Answer explanation

The measure of an inscribed angle is equal to one-half the measure of its intercepted arc.
