When the ball reaches the ground, its height is 0.
We set the height function equal to zero and solve for t, the time.
h = -16t^2 + 250
-16t^2 + 250 = 0
16t^2 - 250 = 0
or
or
or
We discard the negative solution since time must be positive.
The positive solution is
Answer: 4.0 seconds
Answer:

I’m pretty sure it’s seats. If it isn’t that then it’s prolly seat width. Sorry if it’s wring I’m doing the quiz too
Answer:
Step-by-step explanation:
This is a difference of squares polynomial of the form . Since and are both perfect squares then take the square root of each so a= and b=.
We have another difference of squares and repeat the process.
Notice that a sum of squares is not factorable.
Of course for a rectangle A = L × W and we need to be careful about the units.
Here that's
18900 sq cm = L × 180 cm
where the area's in sq cm so we converted the width. We get
L = 18900 / 180 = 105 cm
We're asked for the result in meters, so that's
Answer: 1.05 m
The perimeter of the outer rectangle is
18.4 m + 32.5 m + 18.4 m + 32.5 m = 101.8 m
Answer: 101.8 m
The area of the seating space is the big rectangle minus the small rectangle,
A = 18.4(32.5) - 15(28) = 178 sq m
Answer: 178 sq m
