Answer:
The maximum height that the ball will reach is 81 ft
Step-by-step explanation:
Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.
For an equation of the form

So
the t coordinate of the vertice is:

In this case the equation is:

So

Therefore


Finally the maximum height that the ball will reach is


Slope = (-1 + 3)/(-4 + 3) = 2/-1 = -2
answer
slope of PQ = -2
Hi again............. I am glad to help you again.
6x + 35 + 9x = 15x(x+4) -25
6x + 35 + 9x = 15x² + 60x - 25
15x + 35 = 15x² + 60x - 25
Now, we gonna put all the common terms together
15x - 60x + 35 + 25 - 15x² =
-45x + 60 - 15x² = 0
Now, we need to factorize
-15(x-1)(x+4)=0
Set factors equal to 0
x -1 = 0 or x + 4 = 0
x = 1 or x = 4
I hope that's help !
We are taking one quarter of the 2/5 of the students who play sports.
one quarter of 2/5 is 2/20 or 1/10.
5 x 10^5 = 500,000
2 x 10^5 = 200,000
The scientific notation 5 x 10^5 is 2.5 times greater than the scientific notation of 2 x 10^5.
