The ball is dropped from a building and the quadratic function which models the ball`s height is:
h ( t ) = - 16.1 t² + 150
We can find the initial height if we calculate h ( 0 ), or the height for : t = 0 sec.
h ( 0 ) = -16.1 · 0² + 150 = 0 + 150 = 150 ft
Answer:
The ball was dropped from 150 feet.
Y = 2.5x - 500
I simplified it a bit, you could write it as y = 5x - 2.5x - 500
Answer: the answ4r to this math problem is 46.5
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given: The attachment
Required: Determine the equation
We start by picking any two equivalent points on the table:


Next, we determine the slope, M:




The equation is then calculated as:

Where:


So, we have:

Open bracket

Collect like terms


Hence, the equation is: 
Answer:
If you are asking,
5x - 4x^2=0
x(5-4x)=0
Either,
x=0
or,
5-4x=0
x=5/4
If factor,
5x - 4x^2
x(5-4x)
If difference,
5x - 4x^2
The same as they are not like terms.
