Eli and Karl each throw a basketball straight up in the air at the same time. Eli is standing on a deck and the height of his ba

tino4ka555 [31]

We are to find the time at which the height of basketball thrown by Eli and Karl is equal. We have the functions which model the heights of both basketballs. So by equating the functions representing the height of both basketballs we can find the value of x from that equation at which the height is same for both basketballs.

$-4.9 x^{2} +12x+2.5=-4.9 x^{2} +14x \\ \\ 
12x+2.5=14x \\ \\ 
2.5=2x \\ \\ 
x=1.25$

Thus after 1.25 seconds the height of basketballs thrown by Eli and Karl will be at the same height. This can be verified by finding the heights of both at x=1.25

For Eli:
$Height=f(1.25)=-4.9 (1.25)^{2}+12(1.25)+2.5=9.84375$

For Karl:
$Height=f(1.25)=-4.9 (1.25)^{2}+14(1.25)=9.84375$

Thus height of both basketball is equal after 1.25 seconds

Find the midpoint of the line segment with end coordinates of:

Arisa [49]

Answer:

The midpoint of this line segment is (-1.5, -4.5).

Step-by-step explanation:

In finding the midpoint of a line segment we are actually averaging the x- and y-coordinates of the endpoints:

-2 -1

x-coordinate of midpoint = --------- = -3/2 = -1.5

2

-4 -5

y-coordinate of midpoint = ---------- = -4.5

2

The midpoint of this line segment is (-1.5, -4.5).

9514 1404 393

Answer:

D. 7

Step-by-step explanation:

The equation is ...

x = a(y +1)² -3

For the point (x, y) = (4, 0), we have ...

4 = a(0 -1)² -3

7 = a . . . . . . . . . . . . add 3, simplify

The leading coefficient is 7.
