A projectile is shot into the air. The altitude of the projectile after seconds is modeled by the function graphed. Time is measured in seconds and altitude ℎ() is measured in feet. Which of these statements is true?
A.
The projectile reaches a maximum altitude of 12 feet.
B.
The projectile reaches its maximum altitude after 12 seconds of flight.
C.
The projectile is launched from the ground.
D.
The altitude of the projectile is increasing on the interval 5 < < 20.

B. The projectile reaches its maximum altitude after 12 seconds of flight.

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.

answer: '

the distance between points l and m
