Answer:

the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.

Step-by-step explanation:

Let's denote the angles of the triangle as 3x, 4x, and 5x, where x is a constant.

Since the sum of the angles of a triangle is 180 degrees, we can write the following equation:

3x + 4x + 5x = 180

Simplifying this equation, we get:

12x = 180

Dividing both sides by 12, we get:

x = 15

Therefore, the angles of the triangle are:

3x = 3(15) = 45 degrees

4x = 4(15) = 60 degrees

5x = 5(15) = 75 degrees

So the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.

Marcus is 30 years younger than his mother. Marcus' mother's current age is 35 years old.

To find Marcus' mother's current age, we need to use a system of equations.

Let:

x = Marcus' current age

y = his mother's current age.

We can write two equations based on the information given:

x = y - 30 (Marcus is 30 years younger than his mother)
x + 5 = 1/4(y + 5) (In 5 years, Marcus' age will be 1/4 of his mother's age)

Now we can substitute the first equation into the second equation and solve for y:

y - 30 + 5 = 1/4(y + 5)
y - 25 = 1/4y + 5/4
(3/4) y = 105/4
y = 105/3 = 35

So Marcus' mother's current age is 35 years old.

This equation reflects the passenger's height above the ground after t minutes: H = 14 + 3 + (10)sin(2πt/11) + (3)sin(2πt/6).

An equation in mathematics is a statement that two mathematical expressions are equal. Equations are used to represent mathematical relationships and to describe the behavior of systems or processes. An equation typically consists of two sides, separated by an equal sign (=). On one side of the equal sign is the expression representing what is known or given, and on the other side is the expression representing what is being found or sought. Equations can be used to model real-world situations, to describe the behavior of mathematical functions, to solve problems, and to make predictions. They are an important tool in many areas of mathematics and science, including algebra, calculus, physics, and engineering.

Here,

The height of a passenger on a double Ferris wheel can be calculated by considering the combined effect of two rotations: the rotation of the large arm and the rotation of the smaller wheel.

Let's call the length of the small arm as x, which is equal to half of the diameter of the small wheel, i.e. x = 3.

At time t = 0, the passenger is at point P, which is x meters above the ground. As the large arm rotates, the height of the passenger will change according to the formula:

H = 14 + x + (20/2)sin(2πt/11)

Where H is the height above the ground after t minutes, and (20/2) is half of the diameter of the large arm.

Additionally, as the small wheel rotates, the height of the passenger will change according to the formula:

H = H + (3)sin(2πt/6)

So, combining both the effects, the height of the passenger on the Ferris wheel can be expressed as:

H = 14 + 3 + (10)sin(2πt/11) + (3)sin(2πt/6)

This equation represents the height of the passenger above the ground after t minutes: H = 14 + 3 + (10)sin(2πt/11) + (3)sin(2πt/6).

Step-by-step explanation:

You want to know the work done to empty a half-full spherical tank of radius 3 m containing liquid of density 900 kg/m³ through a 2 m spout at the top of the tank.

The mass of the liquid is the product of its volume and its density. The volume of the hemisphere is ...

  V = 2/3πr³ = 2/3π(3³) = 18π . . . . . . cubic meters

Then the mass of the liquid is ...

  m = ρV = (900 kg/m³)(18π m³) = 16200π kg

The centroid of the liquid is 3/8r below the center of the tank. The mass of liquid must be moved from that location to a point 2 m above the top of the tank. The total height the liquid must be moved is ...

  3/8(3 m) + 3m + 2m = 6.125 m

The work done to lift the liquid is ...

  W = Fd = (m·g)d = (16200π kg)(9.8 m/s²)(6.125 m) = 972405π J

  W ≈ 3,054,900.4 J ≈ 3.0549 MJ

The work required is about 3.0549 megajoules.

__

Additional comment

We could find the incremental work to move a layer of liquid dy thick to the necessary height, then integrate over the depth of liquid. It is much easier to look up the centroid location for a hemisphere, and use that in the calculation.

We have used "m" to represent both mass and meters. We trust you can determine which is which from the context.

If a residual is negative, then that data point lies below the regression line. In a regression analysis, the goal is to find the line that best describes the relationship between two variables.

The line is determined by finding the values of the slope and intercept that minimize the sum of the squared errors between the observed data points and the predicted values on the line.

The difference between the actual value of the dependent variable and the predicted value on the line is known as the residual. A residual represents the vertical distance between the observed data point and the regression line.

If the residual is positive, it means that the observed value is above the regression line, and if the residual is negative, it means that the observed value is below the regression line.

When a residual is negative, it means that the predicted value on the regression line is higher than the actual value of the dependent variable for that particular data point. In other words, the observed data point is lower than what we would expect based on the relationship described by the regression line.

This situation indicates that the regression line may not fit the data very well at that point, and it may be worth investigating further to see if there are other factors that may be affecting the relationship between the two variables.

In summary, a negative residual means that the observed data point lies below the regression line, and it indicates that the regression line may not be the best fit for that particular data point.

To find the units for the rate of change (rise over run), we need to determine the change in y (rise) divided by the change in x (run) for any two points in the table.

Let's choose the first and last points in the table, (5, $35) and (10, $70), respectively. The change in y is $70 - $35 = $35, and the change in x is 10 - 5 = 5. So the rate of change (rise over run) is:

rise/run = $35/5 = $7

Therefore, the best representation for the units of the rate of change is dollars per pound, as the rate of change indicates how much the price changes for every pound of coffee ordered. So the answer is (b) dollars per pound.

Answer:

that these angles are inclusive of 0° and 360° because the question states that 0° ≤ Θ ≤ 360°.

Step-by-step explanation:

If csc Θ is undefined, that means that the sine of the angle is zero, because csc Θ is the reciprocal of the sine function, and division by zero is undefined.

So we need to find all the angles where sin Θ = 0.

The sine function is equal to zero at multiples of 180 degrees, so the solutions to sin Θ = 0 are:

Θ = 0°, 180°, 360°

Note that these angles are inclusive of 0° and 360° because the question states that 0° ≤ Θ ≤ 360°.

What is meant by slope-intercept form of the line equation?

The slope (m) and the y-intercept (b) of a line are highlighted in the slope-intercept form of linear equations (y=mx+b). One of the most popular ways to represent a line's equation is in the slope-intercept form of a straight line. When the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis) are known, the slope-intercept formula can be used to determine the equation of a line. The equation of a line is the equation that each point on the line fulfils.

Given the line passes through the points  (– 8,9) and ( – 2, – 9).

When only two points on the line are given,  the equation of the line is:

y - y₁ = m ( x - x₁)

m = slope = [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex] = (-9 - 9)/ ( -2 -(-8)) = -18/ 6 = -3

For the given data, the best measure of variability is the interquartile range (IQR) and its value is 18.5.

What is variability?

The extent to which data points in a statistical distribution or data collection diverge or vary from the average value, as well as the extent to which these data points differ from one another, is practically by definition the concept of variability.

The given stem and leaf plot is:

stem          leaf

0                 5

2                  4,6,8

3                   2

5                    8

The value in the stem is the ten's place and the value in the leaf is the one's place.

So the scores are 05, 10, 13, 17, 24, 26, 28, 32 and 58.

Because extreme values and outliers have a smaller impact on the interquartile range than the complete data range, statisticians prefer using them to measure variability. To understand the centre and spread of your data, utilise the IQR along with a measure of central tendency, like the median.

Range for this data = 58 - 5 = 53.

To find the Inter Quartile Range (IQR), we first find the median.

Median = 24

So Q1 is the first quartile.

This is the median of the first half of the scores(5,10,13,17).

Q1 = 10+13 / 2 = 11.5

Q3 is the third quartile.

This is the median of the second half of the scores (26, 28, 32 58).

Q3 = 28+32 / 2 = 30

Now,

IQR = Q3 - Q1 = 30 - 11.5 = 18.5

Therefore for the given data, the best measure of variability is the interquartile range (IQR) and its value is 18.5.
