Which system models the height of the tennis ball and the height of the dog's mouth over time? h = 4. 5t 18 and h = -16t2 1. 5t 21 h = 18t 4. 5 and h =-16t2 21t 1. 5 h = -16t2 4. 5t 18 and h = -16t2 1. 5t 14 h = -16t2 18t 4. 5 and h = -16t2 21t 1. 5.

Respuesta :

Answer:

your answer to this question is D

h = -16t^2 + 18t + 4.5 and h = -16t^2 + 21t + 1.5

and the next question:

What does the t-coordinate of the solution to this system represent?

  1. the time at which the ball and the dog hit the ground
  2. the time at which the ball and the dog begin moving
  3. the time at which the ball and the dog's mouth are at the same height

the answer is C!

Hope this helps! can I get brainliest if I deserve it? Thanks! Have a good day! :)
