Aball is thrown in the air from a ledge. its height in feet is represented by  f(x) = –16(x^2 – 5x – 6), where x is the number of seconds since the ball has been thrown. the height of the ball is 0 feet when it hits the ground. how many seconds does it take the ball to reach the ground? as

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

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.
