What the best interpertation of the slope of the line

1 answer:

8 0

The slope of the line is the line of best fit, and it shows that even though all the points are different, they are all in the same area and they are increasing

Answer:

$\frac{dh}{dt}$ ≅ $0.286\frac{ft^{3} }{min}$

Step-by-step explanation:

$V=\frac{\pi }{3}r^{2}h$ ; rate of change $\frac{dV}{dt}=10\frac{ft^{3} }{min}$ , we must find the rate of change of the depth $\frac{dh}{dt} =?;h=8ft$

5h=12r; $V=\frac{\pi }{3}\({\((5h}/12} )} ^{2}h=\frac{\pi }{3}(\frac{25h^{2} }{144})h; V=\frac{25\pi h^{3}}{432}$ ; deriving $\frac{dV}{dt} = \frac{25\pi }{432}(3h^{2})\frac{dh}{dt}$ → $10=\frac{25\pi h^{2}}{144} \frac{dh}{dt}$ → h=8 then $\frac{dh}{dt}=\frac{1440}{25\pi 64}=\frac{9}{10\pi}$ ≅ 0.286 $\frac{ft^{3} }{min}$
