The height, h, in feet of a ball above the ground is given by h = −16t2 + 64t + 80, where t is the time in seconds. How long doe

Gwar [14]

Answer:

t = 5 seconds

Step-by-step explanation:

It is given that, the height h, in feet of a ball above the ground is given by :

$h=-16t^2+64t+80$

Where t is in seconds

We need to find how long does it take the ball to hit the ground? When it hits the ground, its height will be equal to 0. So,

$-16t^2+64t+80=0\\\\t=\dfrac{-64\pm \sqrt{(64)^2-4\times (-16)(80)} }{2\times -16}\\\\t=\dfrac{-64+ \sqrt{(64)^2-4\times (-16)(80)} }{2\times -16},\dfrac{-64-\sqrt{(64)^2-4\times (-16)(80)} }{2\times -16}\\\\t=-1\ s\ \text{and}\ t=5\ s$

Neglecting negative time.

It means ball will take 5 seconds to hit the ground.

Find the distance x rounded to<br> the nearest tenth.

anyanavicka [17]

Answer:

$x=0.1 ~ft$

Step-by-step explanation:

$cot30=\frac{B}{H} =\frac{B}{H}$

$\frac{\sqrt{3} }{2} =\frac{B}{H}=H=\frac{16}{\sqrt{3} }$

$sin70=\frac{X}{H} =\frac{P}{H}$

$sin70=\frac{x}{\frac{16}{\sqrt{3} } }$

$x=\frac{\sqrt{3} }{16 ~sin70}$

$=0.1152$

$x=0.1$

hope it helps

have a great day!!
