A potter forms a piece of clay into a cylinder. As he rolls it, the length, L, of the cylinder increases and the radius, r, decr

Elena L [17]

Answer:

$0.0727 cm\: per\: second$

Step-by-step explanation:

The Volume of the cylinder is constant

Volume of a cylinder, $V=\pi r^2h$

Given:

$\frac{dh}{dt}=0.8 cm/sec\\ r=2cm\\h=11cm\\\frac{dr}{dt}=?$

$\frac{dV}{dt}=\pi r^2 \frac{dh}{dt} + 2\pi r h\frac{dr}{dt}$

$0=\pi* 2^2*0.8 + 2\pi*2*11\frac{dr}{dt}\\0=3.2\pi+44\pi\frac{dr}{dt}\\44\pi\frac{dr}{dt}=-3.2\pi\\\frac{dr}{dt}=\frac{-3.2\pi}{44\pi} \\\frac{dr}{dt}=-0.0727 cm\: per\: second$

The radius is decreasing at a rate of $0.0727 cm\: per\: second$

4x - 3y =24 <br>Find the x and y intercept then use them to graph the line

coldgirl [10]

Answer:

y=21-7x

-7 is your slope

21 is your y-intercept

Step-by-step explanation:

you send the 4x the other side and you send the other side opposite so it going to be -4x

-3y= 24-4x

than you divide -3 on 24 and -4x
