We set up an equation: ?/43 -87= -75
⇒ ?/43= -75+ 87
⇒ ?/43= 12
⇒ ?= 12*43
⇒ ?= 516
The unknown number is 516~
Answer:
Last one
t = 1.5; it takes 1.5 seconds to reach the maximum height of 36 meters.
Step-by-step explanation:
h(t) = −16t² + 48t
h(t) = -16(t² - 3t)
h(t) = -16(t² - 2(t)(1.5) + 1.5² - 1.5²)
h(t) = -16(t - 1.5)² + 36
Axis of symmetry:
t = 1.5
Max height = 36
