I believe they are all equivalent

Ex.). If angles A, B, and C are all complementary to an angle that is 30 degrees, then all three would be 60 degrees (60+30=90)

Veseljchak [2.6K]

Answer:

3694.5 yd^3

Step-by-step explanation:

cone volume equation:

π x $r^{2}$ x $\frac{h}{3}$

π (28 yd/2)^2 x (18/3)

π x 196 x 6

3694.5 yd^3

Tom throws a ball into the air. The ball travels on a parabolic path represented by the equation , where represents the height o

tigry1 [53]

Answer:

2.5 second

Step-by-step explanation:

The equation is missing in the question.

The equation is, $h=-8t^2+40t$ , where 'h' is the height and 't' is time measured in second.

Now we know to reach its maximum height, h in t seconds, the derivative of h with respect to time t is given by :

$\frac{dh}{dt} =0$

Now the differentiating the equation with respect to time t, we get

$\frac{dh}{dt}=\frac{d}{dt}(-8t^2+40t)$

$\frac{dh}{dt}=-16t+40$

For maximum height, $\frac{dh}{dt} =0$

So, $-16t+40=0$

$\Rightarrow 16t=40$

$\Rightarrow t=\frac{40}{16}$

$\Rightarrrow t = 2.5$

Therefore, the ball takes 2.5 seconds time to reach the maximum height.
