The function H(t) = −16t2 + 60t + 95 shows the height H(t), in feet, of a projectile after t seconds. A second object moves in the air along a path represented by g(t) = 20 + 38.7t, where g(t) is the height, in feet, of the object from the ground at time t seconds. Part A: Create a table using integers 1 through 4 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? (6 points) Part B: Explain what the solution from Part A means in the context of the problem. (4 points)

i don't think I'm doing it right, can you do the last two on your own while I do them? We check on each others.

well... try to do the table see what you get... and post it, if you need to, just take a screenshot of it or paste here

Not sure what I did wrong. I plugged in all the numbers and solved. @jim_thompson5910

Hmmm... What should I do?

if t = 1, then h(t) = -16t^2 + 60t + 95 h(1) = -16(1)^2 + 60(1) + 95 h(1) = -16(1) + 60(1) + 95 h(1) = -16 + 60 + 95 h(1) = 139

do the same for t = 2 through t = 4

Let's do the second part "Part B: Explain what the solution from Part A means in the context of the problem. (4 points)"

Part B: The solution for Part A has meaning in the context of the problem by showing how many seconds it would take for both objects to be at the same height.

Is that correct?
jdoe0001
  • jdoe0001
yes, I'd say so
jim_thompson5910
  • jim_thompson5910
yeah the point of intersection represents when h(t) = g(t) at the same time value t

  • jdoe0001
your table for part A is off though

look back at how I computed h(1)
