Need help like right now.

Let's go:

Big triangle:

12 + 3x - 6 = 3x + 6

10 + 8 = 18

$\frac{10}{18} = \frac{3x - 6}{3x + 6} \\\\ 10.(3x + 6) = 18.(3x - 6) \\\ 30x + 60 = 54x - 108 \\\ 54x - 30x = 60 + 108 \\\ 24x = 168 \\\ x = 7$

I hope I helped you.

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

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

$h=81\ ft$
