If a superball is bounced from a height of 20 feet, the function
f(x)  20 (0.9)x gives the height of the ball in feet of each bounce,
where x is the bounce number. What will be the height of the
6th bounce? Round your answer to the nearest tenth of a foot.

step-by-step explanation:

from my conclusion c

the first one, all those points on the line just make a strait line.

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.
