Answer:0.0770

Step-by-step explanation:

0.076952 the five makes 9 round up.

Since you can't have ten the six increases by 1 so it is

0.077

Then you could add a zero on the end to 0.0770 so it is to 3 sig fig

Answer:

0.0770.

Step-by-step explanation:

That would be rounded to the next 3 digits after the second 0.

So it is 0.0770.

(The 7695 is rounded to 770 because the digit after the 9 is 5, so the 69 is rounded up to 70).

Step-by-step explanation:

The volume of the conical pile is given by

$V = \dfrac{\pi}{3}r^2h$

Taking the derivative of V with respect to time, we get

$\dfrac{dV}{dt} = \dfrac{\pi}{3}\dfrac{d}{dt}(r^2h)$

$\:\:\:\:\:\:\:= \dfrac{\pi}{3}\left(2rh\dfrac{dr}{dt} + r^2\dfrac{dh}{dt}\right)$

Since r is always equal to h, we can set

$\dfrac{dr}{dt} = \dfrac{dh}{dt}$

so that our expression for dV/dt becomes

$\dfrac{dV}{dt} = \dfrac{\pi}{3}\left(3r^2\dfrac{dh}{dt}\right)$

$\:\:\:\:\:\:\:= \pi r^2\dfrac{dh}{dt}$

Solving for dh/dt, we get

$\dfrac{dh}{dt} = \dfrac{1}{\pi r^2}\dfrac{dV}{dt}$

$\:\:\:\:\:\:\:= \dfrac{1}{9\pi\:\text{m}^2}(36\:\text{m}^3\text{/s})$

$\:\:\:\:\:\:\:= \dfrac{4}{\pi}\:\text{m/s}$

Draw a line segment and copy it to the right of the original segment and explain your steps and justify each step used.

ozzi

I think this is how you do it: A line of segment is a line with a circular round ball at each end of the line. The line can be straight or diagnal. You draw that, and then draw a line like that right next to the line that you just drew. Then you explain how you did that/ your steps.
