(MGSE9-12.F. JF.6) The height of a ball kicked in the air is modeled by the equation h (t) = -2t2 +8t +24, where h is the height of the ball in feet and t is the time in seconds.
What is the average rate of change of the function over the interval t = 2 to t= 5?
A. -3, B.-6, C. 3, D. 6

answer is:

1.75 pounds

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

  the correct choice is marked
