a sales team estimates that the number of a new phones they will sell is a function of the price that they set. they estimate that if they set the price at x dollars, they will sell f(x)=1720-5x phones. therefor the company’s revenue is x•(1720-5x). find the price x which will maximize the company’s revenue

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.
