a flywheel in the form of a uniformly thick disk of radius 1.58 m1.58 m has a mass of 91.6 kg91.6 kg and spins counterclockwise at 477 rpm477 rpm .
The rotational kinetic energy of the flywheel is 572,819 J.
The flywheel you described has a radius of 1.58 m and a mass of 91.6 kg. It is spinning counterclockwise at 477 rpm. This means it has a certain amount of rotational kinetic energy, which is proportional to both its mass and its speed of rotation. The formula for rotational kinetic energy is 1/2*I*w^2, where I is the moment of inertia (a measure of how spread out the mass is in the object) and w is the angular velocity (the speed of rotation in radians per second).
To find the moment of inertia of the disk, we can use the formula I = 1/2*m*r^2, where m is the mass and r is the radius. Plugging in the values given, we get I = 1/2*91.6 kg*(1.58 m)^2 = 228.6 kg*m^2.
To convert the rotational speed from rpm to radians per second, we need to multiply by 2*pi/60. So, w = 477 rpm * 2*pi/60 = 50.04 rad/s.
Using these values, we can calculate the rotational kinetic energy of the flywheel as 1/2*(228.6 kg*m^2)*(50.04 rad/s)^2 = 572,819 J.

alecla runs the air conditioner in her home when it is hot outside. she uses the equation c = 0.01m to determine the cost, c, in dollars, to run the
air conditioner for m minutes.
according to the equation, what is the cost per minute of running alecia's air conditioner?
The cost per minute of running Alecia's air conditioner is $0.01.
The equation c = 0.01m represents a linear relationship between the cost, c, and the number of minutes, m, that Alecia runs her air conditioner. In this equation, 0.01 is the coefficient of m, which indicates the cost per minute.
To understand the cost per minute, let's consider an example. Suppose Alecia runs her air conditioner for 10 minutes. We can substitute this value into the equation to find the corresponding cost:
c = 0.01m
c = 0.01 * 10
c = 0.10
From this calculation, we see that running the air conditioner for 10 minutes would cost $0.10.
By examining different values of m, we can observe that for each additional minute the air conditioner is run, the cost increases by $0.01. This means that the cost per minute of running the air conditioner remains constant at $0.01.
In summary, according to the equation c = 0.01m, the cost per minute of running Alecia's air conditioner is $0.01. Regardless of the specific number of minutes, each minute of operation incurs a cost of $0.01.

The answer is (d) Standard Error of the Estimate. This measures how far the observed values are from the predicted values in a regression model.
It provides an estimate of the variability around the regression line. The lower the standard error of the estimate, the better the regression equation fits the data.
The coefficient of determination (a) measures the proportion of the variance in the dependent variable that is explained by the independent variable(s) in the regression model. The correlation coefficient (c) measures the strength and direction of the linear relationship between two variables. The standard error of the slope (b) measures the precision of the estimated slope coefficient in a regression model.
In summary, the standard error of the estimate measures the variability around the regression line, and provides an estimate of how consistent the slope of the regression equation would be if multiple samples were selected from the population. It is an important measure of the goodness of fit of the regression model, and can be used to assess the accuracy and reliability of the predictions made by the model.

Write an equation for the line through the point (1,3) parallel to
the line y =
1/2x + 10.
Answer:
y=1/2x+5/2
Step-by-step explanation:
The slope will not change if the line is parallel.
So start with 1/2x and plug in 1.
You will get 1/2 and you need to get a total of 6/2 to get a y of 3.
since you already have 1/2 the remanding value needed is 5/2 and once you add the two you will get 6/2 which equals a y of 3.
y=-4x+6

A rectangular window is 36 in long and 24 in wide. Charmaine would like to buy a screen for the window. The cost of the screen is based on the number of square feet the screen is. Use the facts to find the area of the window in square feet.
As a result, the window has a 6 square feet square space.
What makes something rectangular?
It features four right angles and two sets of parallel sides. An equiangular quadrilateral is another name for a rectangle. The reason for this is that a rectangle is indeed a quadrilateral form (4-sided shape) with parallel sides that are equal to each other and four corners with 90-degree angles.
Since area is usually measured in square feet, we must convert the provided dimensions from inches to feet in order to determine the window's area in square feet. 12 centimeters make up one foot, so
Length in feet = 36 inches / 12 inches/foot = 3 feet
Width in feet = 24 inches / 12 inches/foot = 2 feet
The window's square-footage is as follows:
Area = Length x Width = 3 feet x 2 feet = 6 square feet
Therefore, the area of the window in square feet is 6 square feet.

Write the equation of the line parallel to 2x - 6y = 12 that passes through the point ( -1, 4).
Answer:
y = 1/3x + 4 1/3
Step-by-step explanation:
2x - 6y = 12
First find the slope
Solve for y
Subtract 2x
2x - 6y -2x= 12-2x
-6y = -2x+12
Divide by -6
-6y/-6 =-2x/-6 +12/-6
y = 1/3 x -2
The slope is 1/3
Parallel lines have the same slope
Using the slope intercept form y = mx+b where m is the slope and b is the y intercept
y = 1/3x +b
And substituting in the point
4 = 1/3 (-1) +b
4 = -1/3 +b
Add 1/3 to each side
4 + 1/3 = b
y = 1/3x + 4 1/3

for how many n ∈{1,2,... ,500}is n a multiple of one or more of 5, 6, or 7?
There are 160 numbers between 1 and 500 that are multiples of one or more of 5, 6, or 7.
How to find is n a multiple of one or more of 5, 6, or 7?To solve this problem, we need to use the inclusion-exclusion principle.
First, we find the number of multiples of 5 between 1 and 500:
⌊500/5⌋ = 100
Similarly, the number of multiples of 6 and 7 between 1 and 500 are:
⌊500/6⌋ = 83
⌊500/7⌋ = 71
Next, we find the number of multiples of both 5 and 6, both 5 and 7, and both 6 and 7 between 1 and 500:
Multiples of both 5 and 6: ⌊500/lcm(5,6)⌋ = 41
Multiples of both 5 and 7: ⌊500/lcm(5,7)⌋ = 35
Multiples of both 6 and 7: ⌊500/lcm(6,7)⌋ = 29
Finally, we find the number of multiples of all three 5, 6, and 7:
Multiples of 5, 6, and 7: ⌊500/lcm(5,6,7)⌋ = 11
By the inclusion-exclusion principle, the total number of numbers that are multiples of one or more of 5, 6, or 7 is:
n(5) + n(6) + n(7) - n(5,6) - n(5,7) - n(6,7) + n(5,6,7)
= 100 + 83 + 71 - 41 - 35 - 29 + 11
= 160
Therefore, there are 160 numbers between 1 and 500 that are multiples of one or more of 5, 6, or 7.
