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:

Since the radius is a constant 3 meters:

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 />
<em />
Implicitly differentiate:

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

Therefore:

In conclusion, the water level is rising at a rate of approximately 0.1415 meters per minute.
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.
Y-2=6x+12
add the 2 on both sides
y=6x+14
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
6=8
