Step-by-step explanation:
f(-1) =4.5
use this desmos, desmos is the best graphing calculator
Answer:
First, convert the ft to standard units of meters.
1 foot = 0.3048 meters
Therefore,
484 ft = 147.5232 meters
Then, we will use the laws of motion to calculate the time:
x = 0.5 at^2
where:
x is the displacement
a is the gravity (9.8 m/sec^2)
t is the time taken
Substitute in the equation with the givens to calculate the time as follows:
147.5232 = (0.5 x 9.8) t^2
t^2 = 147.5232 / (0.5 x 9.8)
t^2 = 30.11 seconds
t = 5.49
HOPE THIS HELPED!!!!!!!XDD
