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

Step-by-step explanation:
happy to help
6-2+4-8
= 4+4-8
= 8-8
= 0
Remember that multiplying is how many times you add a number to itself. If you multiply by 3, you add the first number to itself 3 times.
When you multiply a given number by 1, you get the first number (it doesn't change).
When you multiply by a number less than one, say, one half, you'll end up with half of the original number --> a smaller number.
When you multiply a number by more than one, you will get a number bigger than the original because you are adding it to itself more than once. Even if it is a fraction or decimal, if it is greater than 1, then the new product will be larger than the original number.
Hope this helps! :)
By a 6th grader-----------------------------------------------------------------------------------------------find # that is a common multiple of 2 and 7 - the denominators ( 14 )
then do:
denominator stays same - if improper fraction change to mixed #
1 times 7 = 7 + 3 times 2 = 6
2 times 7 = 14 7 times 2 = 14
6 + 7 over 14 is 13 over
14
if possible and needed - change to simplest form
