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

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

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

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

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

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

F(x)=x^2+3x-5. find and simplify f(x+h)-f(x)

jarptica [38.1K]

Answer:

$f(x + h) - f(x) = h^2 + 3h - 5$

Step-by-step explanation:

Given

$f(x) = x^2 + 3x - 5$

Required

Find f(x + h) - f(x)

In functions:

$f(x + h) = f(x) + f(h)$

So:

$f(x + h) - f(x) = f(x) + f(h) - f(x)$

Collect Like Terms

$f(x + h) - f(x) = f(x) - f(x)+ f(h)$

$f(x + h) - f(x) = f(h)$

Solving for f(h)

$f(h) = h^2 + 3h - 5$

So:

$f(x + h) - f(x) = h^2 + 3h - 5$
