Water flows into a right cylindrical shaped swimming pool with a circular base at a rate of 4 m33/min. The radius of the base is
Sloan [31]

Answer:

The water level is rising at a rate of approximately 0.1415 meters per minute.

Step-by-step explanation:

Water is flowing into a right cylindrical-shaped swimming pool at a rate of 4 cubic meters per minute. The radius of the base is 3 meters.

And we want to determine the rate at which the water level of the pool is rising.

Recall that the volume of a cylinder is given by:

\displaystyle V = \pi r^ 2h

Since the radius is a constant 3 meters:

\displaystyle V = 9\pi h

Water is flowing at a rate of 4 cubic meters per minute. In other words, dV/dt = 4 m³ / min.

Take the derivative of both sides with respect to <em>t: </em>

<em />\displaystyle \frac{d}{dt}\left[ V\right] = \frac{d}{dt}\left[ 9\pi h\right]<em />

Implicitly differentiate:

\displaystyle \frac{dV}{dt} = 9\pi \frac{dh}{dt}

The rate at which the water level is rising is represented by dh/dt. Substitute and solve:

\displaystyle \left(4 \right) = 9\pi \frac{dh}{dt}

Therefore:

\displaystyle \frac{dh}{dt} = \frac{4}{9\pi} \approx 0.1415\text{ m/min}

In conclusion, the water level is rising at a rate of approximately 0.1415 meters per minute.

In a 30-60-90 triangle, the length of the long leg is 8. Find the length of the hypotenuse.
fiasKO [112]

Answer:

Step-by-step explanation:

In a 30-60-90 triangle, the ratio of the lengths of the angles' opposite sides are <em>1-√3-2</em>.

If the long leg is 8, then the short one is 8/√3, or <em>8√3/3</em>.

Therefore, the hypotenuse, which is <em>double the short leg</em>, is 16√3/3.

What is x when 5(2x+1)=10x
Gnoma [55]

Step-by-step explanation:

1.before starting first collect the like terms.

5(2x+1)=10x

the like terms are 10x and 2x

2. 5+1=10x-2x because the 2x us crosing the equality sign

that is
