Explanation:

Expression: d = 16t² where d is distance. t is time.

1)

Here t = 2

d = 16(2)²

d = 64 feet

2)

h = 906-t²

h = 906 - 16(2)²

h = 842 feet

3)

expression of height: y = 906 - 16t²

Answer:

  1. 64
  2. 842
  3. y = 906 - 16t²

Step-by-step explanation:

Q1

  • Distance travelled in 2 second
  • 16(2)²
  • 64 feet

Q2

  • Height of object after 2 seconds
  • 906 - 64
  • 842 feet

Q3

  • height of object t seconds after it is dropped
  • y = 906 - 16t²
