Answer:

37.68 cubic units

Step-by-step explanation:

Volume of a cone = πr² [tex]\frac{h}{3}[/tex]

Volume = 3.14 * 3² * [tex]\frac{4}{3}[/tex]

Volume = 3.14 * 9 * [tex]\frac{4}{3}[/tex]

Volume = 3.14 * 3 * 4...(we can cancel out the 3 by dividing 9 by 3)

Volume = 3.14 * 12

The breakeven point is the point at which a company's revenue is equal to its costs. In this case, the combined fixed and variable expenses for the production and sale of 500,000 items are $10,000,000, so the breakeven point for this item would be $10,000,000 / 500,000 items = $100000000/500000=$20 per item.

To determine the price at the breakeven point, we need to know the total revenue that the company is aiming to achieve. If the company's goal is to sell the items at a price above the breakeven point in order to make a profit, then the price at the breakeven point would be $20 per item.

However, if the company is simply trying to recover its costs, then the price at the breakeven point would be the same as the breakeven point, or $20 per item.

The quadrilaterals with vertices (a, b) (-b, a) (-a, -b) (b, -a) is square.

A square is a quadrilateral with four equal sides and four equal angles that is a regular quadrilateral. The square's angles are at a straight angle or 90 degrees. The square's diagonals are also equal and split at a 90-degree angle.

A rectangle with two opposite sides that have the same length can also be referred to as a square.

Given the  quadrilaterals with vertices:

(a, b) (-b, a) (-a, -b) (b, -a),

Let A(a, b), B(-b, a),  C(-a, -b),  and D(b, -a) are the vertices,

let a = 1 and b = 2

coordinate is  A(1, 2), B(-2, 1),  C(-1, -2),  and D(2, -1)

distance between two coordinates is given by,

d = √((x₂ – x₁)² + (y₂ – y₁)²)

finding distance between AB, BC, CD, DA

Distance between AB = √((-b – a)² + (a – b)²)

Distance between AB = √((-2 -  1)² + (1 – 2)²)

Distance between AB = √10 units

Distance between BC = √((-1 + 2)² + (-2 + 1)²)

Distance between BC = √10 units

Distance between CD = √((2 + 1)² + (-1 + 2)²)

Distance between CD = √10 units

Distance between DA = √((2 - 1)² + (-1 - 2)²)

Distance between DA = √10 units

since distance between AB = BC = CD = DA

The mean of the given dataset is 42 and mode is 46. SO the option b is correct.

In the given question we have to find the mean and mode of the following data set.

The given data set is

59   16   57   46   58   21   36   41   23   64   20   66   40   51   28   46

We firstly find the mean.

As we know that the mean is the ratio of sum of all number and total number. So

Mean = Sum of All Numbers/Total Number

Sum of all Numbers = 59 + 16 + 57 + 46 + 58 + 21 + 36 + 41 + 23 + 64 + 20 + 66 + 40 + 51 + 28 + 46

Sum of all Numbers = 672

Total Number = 16

Mean = 672/16

Mean = 42

As we know that,

The value that happens most frequently is the mode. The only average that is capable of having zero, one, or multiple values is the mode. Ordering the numbers first aids in determining the mode.

A minimum of 6" - 300.14 of the free conductor must typically be left when wires are drawn to a junction box that measures 12" x 12" x 4" in order to make splices or attach devices like luminaires or other devices.

An electrical conductor is a substance or material that allows electricity to flow through it. When voltage is applied, electrical charge carriers, frequently electrons or ions, move readily from atom to atom in a conductor.

Conductivity, in general, is the property of a material to carry heat or electricity. Electricity can go through a conductor because there is little to no resistance while electrons are moving across it. Copper is among the majority of metals that are thought to be good conductors, whereas insulators and nonmetals are thought to be poor conductors.

Radius of circle is 3.95 meter

What is Radius?

The line segment formed when we connect a point on a circle's circumference to its precise center is referred to as the ring's radius. The radius of a circle is the distance between the center and any point on its circumference.  The diameter is twice the radius. Typically, the radius is denoted by r or R.

As we well aware, the formula for the circle's area is

Area=π[tex]r^{2}[/tex]

From the question, we know that area is 49 ㎡ substituting π=3.14 rearranging the above formula in terms of radius we get

[tex]r=\sqrt{\frac{Area}{3.14} } \\\\r=\sqrt{\frac{49}{3.14} } \\\\r=3.95 m[/tex]

The two variables in a scatter plot are called the x-variable or independent variable and the y-variable or also called dependent variable.

The x-variable is typically plotted along the horizontal axis, and the y-variable is typically plotted along the vertical axis. The x-variable is the variable that is being used to explain or predict changes in the y-variable. In other words, it is the variable that is being manipulated or changed to observe changes in the y-variable.

For example, if the x-variable is a person’s age and the y-variable is their income, then the x-variable is the variable that is being changed (age) to observe changes in the y-variable (income).

Step-by-step explanation:

Step 1: Subtract 3/5 from both sides.

2/5x + 3/5 − 3/5 = 3 - 3/5

The slope is −0.1. Starting at 3.9, the GPA will be decreased by 0.1 for every text sent in class. The answer is the first option.

The equation of a line has the following form:

y = mx+ b

Where m is the slope of the line and b is the intercept with the axis of y.

In this case, the equation is:

y = 3.9 − 0.1x

y = -0.1x + 3.9

Observe that

m = - 0.1

b = 3.9

So if x represents the number of texts sent during classes, this means that x ≥ 0.

When x increases by one unit then y decreases by -0.1. For example when x = 1 then y = 3.9 - 0.1 = 3.8

Then the greatest value it can take the GPA is 3.9. Therefore we can say that the function starts at y = 3.9.

The limit is 32. We can use Taylor series expansion to evaluate the limit.

The Taylor series expansion of sin(4x) around x=0 is 4x - (4x)^3/3! + (4x)^5/5! - ... .

So, sin(4x) = 4x - (4x)^3/3! + (4x)^5/5! - ...

then we can substitute this in the limit expression

As we can see, when x is approaching to 0, the expression in the numerator goes to 32, and the expression in the denominator goes to 0. Therefore the limit is 32.

In this case, we used Taylor series expansion to evaluate the limit, it's a useful tool when the function is not easy to work with or not in a known form. It's based on the idea that a function can be approximated by a polynomial when x is close to a point.

The height of Billy's drawing, obtained by using the scale factor of 0.5 inches is equivalent to 2 feet, and Billy's height of 5'6'' is 1.375 inches.

A scale factor is a number by which the dimensions of the sides (the side lengths) of an original figure is multiplied in other to obtain the dimensions (lengths of the sides) of the image.

The height of Billy's drawing can be obtained by multiplying Billy's height by the scale factor used for the drawing.

The scale of the drawing is 0.5 inches ≡ 2 feet

Billy's height = 5'6'' (5 feet 6 inches)

Dividing both sides of the scale factor by 2, we get;

0.5 inches ÷ 2 ≡ 2 feet ÷ 2

0.25 of an inch ≡ 1 ft

5'6'' (5 feet 6 inches) = 5 feet 6 inches = 5.5 feet

The scale factor equation is; 0.25 of an inch = 1 ft

Here,

Based on standard deviation, the distribution's spread (narrow or wide) is established.

The distribution has a broad spread if the standard deviation is high.

The distribution has a low spread if a standard deviation is minimal.

The standard deviation, often known as the standard error of mean, is uo for the t distribution.

A graph of the image of the triangle with vertices (3, 1), (3, 4), and (1, 4) when reflected across the y-axis is shown in the image attached below.

In Mathematics, a reflection can be defined as a type of transformation which moves every point of the geometric figure by producing a flipped, but mirror image of the geometric figure.

In Geometry, a reflection over the y-axis (y = x) is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, a reflection over the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.

By applying a reflection over the y-axis to the coordinates of this triangle the image coordinates include the following:

(x, y)                               →              (-x, y)

Coordinate A = (3, 1)   →  Coordinate A' = (-(3), 1) = (-3, 1).

Coordinate B = (3, 4)   →  Coordinate B' = (-(3), 4) = (-3, 4).
