A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t)=72t-16t^2. What is the

irakobra [83]

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

$at ^ 2 + bt + c$

the t coordinate of the vertice is:

$t =-\frac{b}{2a}$

In this case the equation is:

$h(t)=72t-16t^2$

$a=-16\\b=72\\c=0$

Therefore

$t =-\frac{72}{2(-16)}$

$t=2.25\ s$

Finally the maximum height that the ball will reach is

$h(2.25)=72(2.25)-16(2.25)^2$

$h=81\ ft$

If K is the midpoint of JL, JK=9x-1 and KL=2x+27, find JL.

ratelena [41]

Answer:

The answer is B. 70

Step-by-step explanation:

First, since K is the midpoint of line segment JL, JK must equal KL.

So, set 9x-1 = 2x+27 and solve.

7x=28 so x=4

Then, since they are asking for JL, using x=4, add together JK and KL.

So, 9x-1+2x+27 = 11x+26 = 11(4) + 26 = 44+26 = 70

Solve the equation for k in terms of h.<br> (h-3k)/2k=-3/4

tatuchka [14]

(h-3k)/2k=-3/4

h-3k=-6k/4

4h-12k=-6k

-12k=-6k-4h

-6k=-4h

Solution: k=2/3h
