A short stop makes an error by dropping the ball. As the ball drops, its height (h) in feet, as a function of time (t) is modeled by h(t) = -16t2 + 3. A slow motion replay of the error shows the play at half speed. What function describes the height of the ball in the replay? (Hint: The function squares the time, so half the time is also squared in the new function.)A)h(t) = -16(0.5t)2 + 1.5B)h(t) = (-16t2 + 3)/2C)h(t) = -16(t/2)2 + 3D)h(t) = -8(t)2 + 3

Answer:
The simplified expression is 9x - 5y.
To simplify the expression we can distribute the negative sign to the parenthesis. We can also get rid of the parenthesis of both terms once we have distributed.
We can now combine like terms:
So, our simplified expression is 9x - 5y.
output 10 13 16 19

Answer:
y = 3n + 7
Step-by-step explanation:
We can calculate a slope for the line defined by these points. (We are told it is linear, so we can use y = mx + b format, where m is the slope and b the y-intercept.)
Slope: I'll pick points (1,10) and (4,19) for calculating the slope:
Rise = (19-10) = 9
Run = (4-1) = 3
Rise/Run, or slope, m = (9/3, or 3
The equation becomes y = 3x + b
We can calculate b by using one of the given points. I'll pick (1,10):
y = 3x + b
10 = 3*(1) + b
b = 7
The equation is y = 3x + 7 It works for the other points (try it).
We can use n for x:
y = 3n + 7
Pick any n, and you'll have the correct outcome.
Answer:
y = 3n + 7
Step-by-step explanation
n | y
---------
1 | 10
2 | 13
3 | 16
4 | 19
slope - (1, 10) ; (2, 13)
m = y1 - y2
-------------
n1 - n2
m = 10 - 13
-----------
1 - 2
m = 3
Slope Intercept Form Equation -
y - y1 = m(n - x1)
y - 10 = 3(n - 1)
y - 10 = 3n - 3
y = 3n - 7

The best estimate for the amount of time elapsed when the object is 120 meters off the ground is 5 seconds
Functions and values
Given the function that represents the approximate height of the object off the ground after x seconds expressed as:
f(x) = -5x^2 + 250
In order to calculate the best estimate for the amount of time elapsed when the object is 120 meters off the ground, you will substitute f(x) = 120 and calculate 'x"
120 = -5x^2 + 250
-130 = -5x^2
x^2 =130/5
x^2 = 26
x = 5 seconds
Hence the best estimate for the amount of time elapsed when the object is 120 meters off the ground is 5 seconds
