Answer:

$\pi$ or 3.1

Step-by-step explanation:

The total area of the circle is $3^2\pi$ . The central angle of the shaded region is 40 degrees so we have to multiply $3^2\pi$ by $\frac{40}{360}$ or $\frac{1}{9}$ . 3 squared is 9 so 9 $\pi$ times $\frac{1}{9}$ is just equal to $\pi$ . $\pi$ =3.14159265... rounded to the nearest tenth is 3.1

The height of a toy rocket that is shot in the air with an upward velocity of 48 feet per second can be modeled by the function

Irina18 [472]

Answer:

B) 36 ft

Step-by-step explanation:

Given:

The height as a function of time is given as:

$f(t)=-16t^2+48t$

At maximum height, the instantaneous velocity becomes 0. The instantaneous velocity is the first derivative of the height function.

So, the derivative of the the given function is 0 at the maximum height.

Differentiating the above function with time, we get

$f'(t)=\frac{d}{dt}(-16t^2)+\frac{d}{dt}(48t)\\f'(t)=-32t+48$

Now, equating the derivative to 0 and finding time.

$f'(t)=0\\-32t+48=0\\32t=48\\t=\frac{48}{32}=1.5\ s$

Therefore, time taken to reach maximum height is 1.5 s.

Now, maximum height is obtained by plugging in $t=1.5$ in the height equation.

Maximum height is given as:

$h_{max}=-16(1.5)^2+48(1.5)\\h_{max}=-16\times 2.25+72\\h_{max}=-36+72\\h_{max}=36\ ft$
