<span>Formula: H(t) = 56t – 16t^2
</span>
H(t) = - 16t^2 + 56t
<span><span>A.
</span>What is the height of the ball after 1 second? H
(1) = 56(1) – 16(1) ^2 = 40 pt.</span>
<span><span>B.
</span>What is the maximum height? X = - (56)/2(- 16) =
1.75 sec h (1.75) = 56(1.75) – 16(1.75) ^2 h (1.75) = 49ft.</span>

Step-by-step explanation:
Divide 1,176 by 12. Do this using a calculator or long division.
Triangle X: 4/5=0.8
Triangle Y: 6/7.5=0.8
(Select the triangles with legs at a ratio of 0.8)
A: 8/10=0.8
B: 3/3.75=0.8
C: 10/12=0.8333333333
D: 12/15=0.8
A, B, and D
I must add though, the wording of this question is very bad.

Answer:
Step-by-step explanation:
Given
From Figure
Sides of Triangle
Now, using concept
Perimeter of triangle = Sum of the sides of triangle
So,
Perimeter of triangle =
Adding and , so,
Perimeter of triangle =
This can be written as
Perimeter of triangle =
Adding 15 and 10,
Perimeter of triangle =
So, the correct choice is =
Hope this helps.
