The initial velocity of the fish is the same as that of the pelican and it is -0.50 m/s. The distance traveled by the object is given by the equation,
d = (V1)t + 0.5at²
where t is equal to 2.50s and the acceleration due to gravity, a, is 9.80 m/s². Substituting,
d = (-0.50 m/s)(2.5 s) + 0.5(9.8 m/s²)(2.50 s)²
d = 30.625 m
Thus, the answer is letter C.

an inverted cone has a height of 11 inches and an initial radius of 18 inches. the volume of the inverted cone is decreasing at

joja [24]

Radius of cone is decreasing at the rate of $\frac{1623}{110\pi}$ inches

What is rate of change?

Suppose there is a function and there are two quantities. If one quantity of a function changes, the rate at which other quantity of the function changes is called rate of change of a function.

Here rate of change of radius of cone has been calculated

Radius of cone = 18 inches

Height of cone = 11 inches

Volume of cone (V) = $\frac{1}{3} \pi r^2h$

$\frac{dV}{dt} = \frac{1}{3} \pi h (2r\frac{dr}{dt})\\-541 = \frac{2}{3} \pi \times 11\times 5\times\frac{dr}{dt}\\\frac{dr}{dt} = -\frac{541 \times 3}{2 \times \pi \times 11 \times 5}\\\frac{dr}{dt} = -\frac{1623}{110 \pi}$
