Answer:
A
Step-by-step explanation:
The projectile motion of Jenny's dive can be represented by 
where a is acceleration, v_0 is velocity, t is time, and h_0 is initial height.
Jenny's vertical height above the water is represented by 
. 10 is h_0 and is Jenny's initial height.

Answer:
- 4
- -2
- 4
- 2
- -2±√2
Step-by-step explanation:
In order to fill the first blank, we need to look at the second line to see what the coefficient of x is.
1. x² +<u> </u><u>4 </u>x +2 = 0
The constant is subtracted from both sides to get the second line.
2. x² +4x = <u> -2 </u>
The value that is added on the third line is the square of half the x-coefficient: (4/2)² = 4
3. x² +4x +<u> 4 </u> = -2 +4
On the fourth line, the left side is written as a square, and the right side is simplified. The square root is taken of both sides.
4. √(x +2)² = ±√<u> 2 </u>
Finally, 2 is subtracted from both sides to find the values of x.
5. x = <u> -2 ±√2 </u>
Answer: n=4
Step-by-step explanation:
add 9 to both sides
divide both sides by -9
