A vertical cylinder is leaking water at a rate of 4m3/sec. If the cylinder has a height of 10m and a radius of 2m, at what rate

Lyrx [107]

Answer:

Therefore the rate change of height is $\frac{1}{\pi}$ m/s.

Step-by-step explanation:

Given that a vertical cylinder is leaking water at rate of 4 m³/s.

It means the rate change of volume is 4 m³/s.

$\frac{dV}{dt}=4 \ m^3/s$

The radius of the cylinder remains constant with respect to time, but the height of the water label changes with respect to time.

The height of the cylinder be h(say).

The volume of a cylinder is $V=\pi r^2 h$

$=( \pi \times 2^2\times h)\ m^3$

$\therefore V= 4\pi h$

Differentiating with respect to t.

$\frac{dV}{dt}=4\pi \frac{dh}{dt}$

Putting the value $\frac{dV}{dt}$

$\Rightarrow 4\pi \frac{dh}{dt}=4$

$\Rightarrow \frac{dh}{dt}=\frac{4}{4\pi}$

$\Rightarrow \frac{dh}{dt}=\frac{1}{\pi}$

The rate change of height does not depend on the height.

Therefore the rate change of height is $\frac{1}{\pi}$ m/s.

Find the magnitude of the vector (3, -6).Write your answer in simplified radical form.0/0 (0,0)X Х5?

bekas [8.4K]

$\begin{gathered} \vec{}v=\text{ (x,y)} \\ \lvert v\rvert=\sqrt[]{x^2+y^2\text{ }}\text{ this is the magnitud of a vector} \\ \text{the radical form is when you expess a number with his roots.} \\ \lvert v\rvert=\sqrt[]{3^2+(-6)^2} \\ \lvert v\rvert=\sqrt[]{9^{}+36} \\ \lvert v\rvert=\sqrt[]{45}\text{ but by law of the radicals can be simplified as follows } \\ \lvert v\rvert=\sqrt[]{5\cdot9}\text{ } \\ \lvert v\rvert=\sqrt[]{5^{}}\text{ }\sqrt[]{9}\text{ = 3 }\sqrt[]{5} \end{gathered}$

Weight Height

Nadya [2.5K]

Use the graphing calculator to plot the line y=ax+b for the given data. On the attached diagram you can see green points that are ordered pairs weight-height and black line is regression line.

As you can see a≈0.1 and b≈50.9.

The equation of regression line is y=0.1x+50.9.
