A woodworker makes wooden checkerboards. Her profit is a function of the price she charges. This graph shows her total profits, y, based on the sales price, x, of
each checkerboard.
Identify any zeros of the function, and interpret what the zeros mean in terms of
the situation.
A. Zero: x = 42.5. This is the selling price that will give her the greatest
profit.
B. Zeros: x = 20 and x = 65. These are the prices at which she makes the
least and greatest amounts of profit.
C. Zeros: x = 20 and x = 65. These are the prices at which she neither
makes nor loses money.
D. Zero: y = 1012.5. This is the maximum amount of profit she can make.

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

correct answer is b. 27/8
