H = 5 + ut - 16t^2
When the balls falls back to the ground, h = 0
0 = 5 + 3.2u - 16(3.2)^2
0 = 5 + 3.2u - 163.84
0 = 3.2u - 158.84
3.2u = 158.84
u = 158.84/3.2 = 49.6 ft/s
Required equation is
h = 5 + 49.6t - 16t^2
I think dialogue sorry if it is wrong
4π radians
<h3>Further explanation</h3>
We provide an angle of 720° that will be instantly converted to radians.
Recognize these:
From the conversion previous we can produce the formula as follows:
We can state the following:
- Degrees to radians, multiply by

- Radians to degrees, multiply by

Given α = 720°. Let us convert this degree to radians.

720° and 180° crossed out. They can be divided by 180°.

Hence, 
- - - - - - -
<u>Another example:</u>
Convert
to degrees.

180° and 3 crossed out. Likewise with π.
Thus,

Answer:
x = - 3 ± 
Step-by-step explanation:
Given
4x² + 24x = 4 ( divide through by 4 )
x² + 6x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 1 + 9
(x + 3)² = 10 ( take the square root of both sides )
x + 3 = ±
( subtract 3 from both sides )
x = - 3 ±
