At a sand and gravel plant, sand is falling off a conveyor and onto a conical pile at a rate of 16 cubic feet per minute. The di

kogti [31]

The rate at which the height of the pile is changing when the height is 2 ft. is 0.5659 ft./min. Computed using differentiation.

The sand is falling onto a conical pile, thus we get the pile in the shape of a cone, whose volume is given as:

V = (1/3)πr²h,

where V represents the volume of the cone, r represents its radius, and h represents its height.

In the question, we are given that the rate of piling is 16 ft.³/min, which implies that:

dV/dt = 16 ... (i)

We are also given that the diameter is three times the altitude (height), which can be shown as:

2r = 3h,

or, r = (3/2)h.

Thus, the volume can now be shown as:

V = (1/3)π{(3/2)h}²h,

or, V = (3πh³)/4.

Differentiating this with respect to time, we get:

dV/dt = (3π/4)(3h²)dh/dt.

Now, we need to calculate the rate of change of height, when the height is 2 feet, thus we take h = 2

Using dV/dt = 16 from (i), we can write:

16 = (3π/4)(3(2)²)dh/dt.,

or, 16 = 9π(dh/dt),

or, dh/dt = 16/9π = 0.5659 ft./min.

Thus, the rate at which the height of the pile is changing when the height is 2 ft. is 0.5659 ft./min.

Please really need anyone’s help on this thank you

When something says 'solve for the system of equations' they are looking for a point where the graph of the two functions intersects. Since they give you the graph, the two functions approximately intersect somewhere between the x-value of -6 and -7 (i.e. -6.5) and somewhere between the y-value of -3 and -4 (i.e. -3.5). So, the closest estimate is (-6.5, -3.5) or A.

Samantha threw an apple out of a window from the tenth floor of her apartment building.The equation y=-16t^2+120 can be used to

Savatey [412]

If the apple is on the ground, then the height y is 0. To find t, just plug in 0 for y:
$0=-16t^{2}+120$
$-120=-16t^{2}$
$t^{2} =7.5$
$t=2.74$

So the answer is 2.74 seconds.

Note that taking the square root of 7.5, mathematically, gives you both 2.74 and -2.74. But because we know that time did not go backwards, only the positive value for t was considered.
