?Use the position equation s = -16t2 + v0t + s0 to write a function that represents the situation and give the average velocity of the object from time t1 to time t2.An object is thrown upward from a height of 38 feet at a velocity of 84 feet per second.
t1 = 1, t2 = 3
A. ?s= -16t2+ 38t + 84; avg. velocity = 79 ft/s
B. ?s = -16t2+ 84t + 38; avg. velocity = 125 ft/s
C. ?s = -16t2+ 38t + 84; avg. velocity = -26 ft/s
D. ?s= -16t2+ 84t + 38; avg. velocity = 20 ft/s
E. ?s= -16t2 + 84t + 38; avg. velocity = 40 ft/s

Find the first term, the common difference, and give a recursive formula for the arithmetic sequence.10th term is -11; 14th term is -51
A. a1 = 89, d = 10, an = an-1 + 10 B. a1 = 79, d = -10, an = an-1 - 10 C. a1 = 89, d = -10, an = an-1 - 10 D. a1 = 79, d = 10, an = an-1 + 10
