A cone has a radius of 5 ft and a height of 15 ft. It is empty and is being filled with water at a constant rate of 15 15 ft 3 f

kvasek [131]

Answer:

$\frac{dr}{dt}=0.11062ft/sec$

Step-by-step explanation:

From the question we are told that:

Radius $r=5ft$

Height $H=15ft$

Rate $R=15ft/3sec =5ft/s$

Surface Radius $R_{surf}=2.2ft$

Generally the equation for Volume is mathematically given by

$V=\frac{1}{3}\pi*r^2h$

Since radius to height ratio gives

$\frac{r}{h}=\frac{5}{15}$

$\frac{r}{h}=\frac{1}{3}$

$h=3r$

Therefore

$V=\frac{1}{3}\pi*r^2(3r)$

$V=\pi r^3$

Generally the equation for Change of Volume is mathematically given by

$\frac{dv}{dt}=\pi \frac{d}{dt}(r^3)$

$\frac{dv}{dt}=\pi 3*r^2 \frac{dr}{dt}$

$\frac{dv}{dt}=\pi 3*(2.2)^2 \frac{dr}{dt}$

$\frac{dr}{dt}=\frac{5}{45.62}$

$\frac{dr}{dt}=0.11062ft/sec$

The table represents a linear function.

melomori [17]

Answer:

Step-by-step explanation:

For it to be a linear function, then it obeys the general form of a liner equation which is y = mx + c

Where m represents the slope and c represents the y intercept

Now let’s take the last point on the table;

and substitute the values of x and y;

we have;

10 = 2m + c. ••••••••(i)

let’s take the second to the last;

7 = m + c ••••••••••(ii)

So let’s solve both equations simultaneously

Just subtract second from first directly

This gives m = 3

1. What are the zeros of the function?

Juliette [100K]

C.

You can factor that equation to the following:

x(x - 3)(x + 2)

Then set each part equal to zero and solve individually.
