A rocket was launched into the air from a podium 6 feet off the ground. The rocket path is represented by the equation h(t)= 16t^2+ 120t +6 , where h(t) represents the height, in feet,
and t is the time, in seconds. Find the average rate of change from the initial launch to the
maximum height.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

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.

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
