Answer: 51.4275 or 51.428571 (repeating decimals) feet
Step-by-step explanation:
P = perimeter
L = length
W = width
Represent W as
Find L
P = 2L + 2W
240 = 2L + 2()
240 = 2L + or you can write 3/2 as 1.5
240 = 2L + 1.5L
240 = 3.5L
L = ≈ 68.57 or 68.571428 (but this is <em>repeating decimals</em> so I rounded it)
Find W
= 51.4275
Or if you want unrounded version 51.428571 (repeating decimals)
Answer:
4 seconds.
Step-by-step explanation:
The given equation is
where, h is height in feet of a golf ball above the ground after being hit into the air and t is the number of seconds elapsed since the ball was hit.
We need to find the time for the ball to hit the ground.
At ground level the height of ball is 0, i.e., h=0.
Using zero product property, we get
Therefore, it will take 4 seconds for the ball to hit the ground.
