Answer:
16.6%
Step-by-step explanation:
The GCF for 84 and 90 is 6.
The factors of 84 are: 1, 2, 3, 4, <u>6</u>, 7, 12, 14, 21, 28, 42, 84
The factors of 90 are: 1, 2, 3, 5, <u>6</u>, 9, 10, 15, 18, 30, 45, 90
Then the greatest common factor is 6.
What are the statements?
52
Given the the equation h(t) =- where t is the time in second
So to find the ball's maximum height we can apply the vertex formula:
t=
to find the "x" value of the vertex, then plug that value into the original equation as a substitute for "x".
Standard quadratic form is:
=> a=15, b=30 in our given equation
<=> t =
When t =-1 we have h(t) = = 52
So the ball's maximum height is: 52
Hope it will find you well.
