The maximum power produced by a power plant with a water fall of 30 m and a flow rate of 10,000 kg/s is 29,430,000 W or 29.4 MW (megawatts).

Hydroelectric power plants use water as a source of energy to produce electricity. This energy is produced by the gravitational force of falling water. A water fall of 30m with a flow rate of 10,000 kg/s is a considerable force that can be harnessed to produce electricity. Here is how to calculate the maximum power produced by a power plant with these parameters:

To calculate the maximum power produced by a hydroelectric power plant, we use the formula:

P = x g x Q x H

Where:
P = Power
= Density of water
g = Acceleration due to gravity
Q = Flow rate
H = Head

Given that:
Head = 30m
Flow rate = 10,000 kg/s

The density of water is 1000 kg/m³, and the acceleration due to gravity is 9.81 m/s². We can substitute these values into the formula and calculate the power:

P = x g x Q x H
P = 1000 kg/m³ x 9.81 m/s² x 10,000 kg/s x 30 m
P = 29,430,000 W

The required length of the missing side is 9.28 units for the given triangle.

As shown triangle:

∠A = 104°

∠B = 47°

∠C = 29°

Side c = 7 units

Let's denote the length of the missing side as x.

Using the Law of Sines:

sin(A)/a = sin(B)/b = sin(C)/c

We know the values of angles A, B, and C, as well as the length of side c. Plugging in these values, we get:

sin(104°)/x = sin(47°)/7

To find x, we can rearrange the equation and solve for x:

x = (7 × sin(104°)) / sin(47°)

Using a calculator, to get the value of x:

x ≈ 9.28

Therefore, the length of side a (in front of angle A) is approximately 9.28 units.

Answer: y = 5x + 26

Step-by-step explanation:

To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Substituting the values, we get:

y - 1 = 5(x - (-5))

Simplifying further:

y - 1 = 5(x + 5)

Expanding the brackets:

y - 1 = 5x + 25

Rearranging the equation to the slope-intercept form (y = mx + b):

y = 5x + 26

Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.

Multicollinearity is indeed a problem in statistical analysis, regardless of whether you are aware of its existence or not. Multicollinearity refers to a high correlation between two or more predictor variables in a regression model.

It can cause issues such as unstable coefficient estimates, difficulty in interpreting the individual effects of predictors, and increased uncertainty in the model's predictions.Even if you are aware of multicollinearity, it doesn't eliminate the problem itself. While awareness can help you be cautious about the interpretation of the coefficients and take appropriate steps, such as examining variance inflation factors (VIF) or using regularization techniques, it does not eliminate the inherent issues caused by multicollinearity.

Therefore, it is important to address multicollinearity in your analysis through methods like removing redundant variables, transforming variables, or using dimensionality reduction techniques to mitigate its impact on the model's results and reliability.

The value of p from the given equation is 4.5.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign \(=\\\).

The given equation is \(0.5p-3.45=-1.2\)

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

The equation can be solved as follows

\(0.5p-3.45=-1.2\)

\(0.5p= -1.2+3.45\)

\(0.5p= 2.25\)

\(p= 2.25\div0.5\)

Based on the price to buy a baker's dozen, the money that the baker will save from buying a Baker's dozen instead of 13 individual rolls is $0.60.

The price per roll is:

= 3.60 / 6

= $0.60

The price of 13 individual rolls is:

= 0.60 x 13

= $7.80

The amount saved is:

= Price of 13 rolls - Price of baker's dozen

Answer: Just use MathPapa.

Step-by-step explanation:

Answer:

See below both methods.

Step-by-step explanation:

9x + 6y = 18

-6x - 6y = -24

Elimination:

9x + 6y = 18

-6x - 6y = -24

Since 6y and -6y add to zero, add the equations to eliminate y and solve for x.

      9x + 6y = 18

(+)   -6x - 6y = -24

-------------------------

       3x        = -6

x = -2

Now we need to eliminate y and solve for x. Divide both sides of the second equation by 6 and multiply both sides of the second equation by 9 to get this new equation.

-9x - 9y = -36

Add this new equation to the first original equation to eliminate x.

      9x + 6y = 18

(+)  -9x - 9y = -36

-------------------------

            -3y = -18

y = 6

Solution: x = -2; y = 6

Substitution:

9x + 6y = 18

-6x - 6y = -24

Divide both sides of the first equation by 3. Divide both sides of the second equation by -6.

3x + 2y = 6    (Equation 1)

x + y = 4     (Equation 2)

Solve the second equation for x.

x = 4 - y

Substitute 4 - y for x in Equation 1 and solve for y.

3(4 - y) + 2y = 6

12 - 3y + 2y = 6

-y + 12 = 6

-y = -6

y = 6

Now substitute 6 for y in equation 2 and solve for x.

x + 6 = 4

x = -2

Solution: x = -2, y = 6

Step-by-step explanation:

Container A is a cylinder so the equation is π(r^2)(h)

Container B is a right cone so that equation is 1/3π(r^2)(h)

You would plug in the numbers and then subtract A from B

The formula to find volume of cylinder of container A is πr²h - 1/3π²h.

Thus Option (c) is correct

The volume of cylinder is "the density of the cylinder which signifies the amount of material the cylinder can carry".

According to the question,

Container A is "cylinder with a cylinder of radius of 10 units and has height is 10 units. Container B is cylinder with a cylinder of radius of 10 units and has height is 10 units. A right cone has base and has a height 10 units.

In order to find volume of container A only if subtract volume of cone from volume of cylinder

Formula for volume of cylinder = πr²h

Formula for volume of cone = 1/3π²h

Formula for volume of container A = πr²h - 1/3π²h
