Water is shot straight up out of a water soaker toy.
The quadratic function y = –16x2 + 32x models the
height in feet of a water droplet after x seconds. How
long is the water droplet in the air?
Help!
Answers
Answer:
The water droplet is in the air for two seconds.
Step-by-step explanation:
You can solve this by finding the times at which its height is zero. The lesser of the two values will be upon launch, and the greater upon landing:
y = -16x² + 32x
Let y = 0
-16x² + 32x = 0
factor -16 out:
x² - 2x = 0
complete the square:
x² - 2x + 1 = 1
and solve for x
(x - 1)² = 1
x - 1 = ±1
x = 1 ± 1
x = 0, 2
So the water is at a height of zero at zero seconds and two seconds. It's thus in the air for two seconds.

(y − h)2 + (x − k)2 = r2
(x − h)2 − (y − k)2 = r2
(y + h)2 − (x + k)2 = r2
(x − h)2 + (y − k)2 = r2
(x + h)2 − (y + k)2 = r2

y = 16.3
Step-by-step explanation:
Based on the altitude theorem of a right triangle, we have:
14 = √(12*y)
Square both sides
14² = 12*y
196 = 12y
Divide both sides by 12
196/12 = 12y/12
16.3 = y
y = 16.3 (nearest tenth)

1) Find the Mean of all the numbers.
3+4+5+7+10+12+15=56
56/7=8 mean is 8
Now We Calculate Standard Deviation:
S=[tex]\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}[/tex]
You take each number from the problem i.e 3,4,5...
and then you subtract the mean from it and then square it.
S=[tex]\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}[/tex]
S=[tex]\sqrt{25+16+9+1+4+16+49}[/tex]
S=[tex]\sqrt{120}[/tex]
S=[tex]\sqrt{120}/7[/tex]
7 is the amount of data units given in the problem.
120/7=17.1428571429
