an auto dealer has 5 different cars and 6 different trucks. how many ways are there to select two vehicles?

Answers

Answer 1

The number of possible ways to select two vehicles = 55

Let m represents the number of cars and n represents the number of trucks.

An auto dealer has 5 different cars and 6 different trucks.

This means that m = 5 and n = 6

so, the total number of vehicles (t) would be,

t = m + n

t = 5 + 6

t = 11

Let us assume that p represents the number of possible ways to select two vehicles.

We use the combination formula.

[tex]^{n}C_r=\frac{n!}{r!(n-r)!}[/tex]

here, n = 11 and r = 2

Using combination formula,

p = [tex]^{11}C_2[/tex]

p = [tex]\frac{11!}{2!\times (11-2)!}[/tex]

p = 55

Therefore, the number of possible ways = 55

A shipping company makes cube-shaped boxes. Their basic box measures 1 foot per side. They want to know how to scale the basic box to build new boxes of various volumes.

1. If the company wants a box with a volume of 8 cubic feet, by what scale factor do they need to dilate the box?

2. If they want a box with a volume of 10 cubic feet, approximately what scale factor do they need?

3. The company decides to create a graph to help analyze the
relationship between volume (x) and scale factor (y). Complete
the table, rounding values to the nearest hundredth if needed.

Then, on graph paper, plot the points and connect them with a smooth curve.

Answers

the points do not fall on a straight line, but rather curve upward as volume increases. This reflects the fact that the scale factor needed to dilate the basic box increases as the volume of the new box increases.

What is volume?

Volume is a physical quantity that measures the amount of space occupied by an object, substance, or material. It is usually measured in cubic units such as cubic meters (m³), cubic centimeters (cm³), cubic feet (ft³), or liters (L).

The volume of an object is determined by its three-dimensional dimensions, namely length, width, and height. For example, the volume of a cube is calculated by multiplying its length, width, and height measurements together.

by the question.

To find the scale factor needed to dilate the basic box to a box with a volume of 8 cubic feet, we can use the formula for the volume of a cube: [tex]V=s^{2}[/tex], where V is the volume and s is the length of one side of the cube.

Thus, we can solve for the new length of one side of the cube, which we'll call x:

[tex]8 = x^{3}[/tex]

Taking the cube root of both sides gives:

x = 2

So, the company would need to dilate the basic box by a scale factor of

2 to create a box with a volume of 8 cubic feet.

To find the approximate scale factor needed to dilate the basic box to a box with a volume of 10 cubic feet, we can use the same formula:

[tex]10 = x^{3}[/tex]

Taking the cube root of both sides gives:

x ≈ 2.154

So, the company would need to dilate the basic box by a scale factor of approximately 2.154 to create a box with a volume of 10 cubic feet.

Using the formula. [tex]V=s^{2}[/tex], we can fill in the table as follows:

Volume (cubic feet) Scale Factor

0                                        0

1                                         1

5                                        1.71

8                                        2

10                                     2.15

15                                        2.47

20                                     2.71

We can then plot these points on a graph with volume on the x-axis and scale factor on the y-axis and connect them with a smooth curve to show the relationship between the two variables.

[tex]10 = x^{3}[/tex]

Taking the cube root of both sides gives:

Solve the system of equations 5x+2y=24
2X+5y=24

Answers

To solve the system of equations:

5x + 2y = 24

2x + 5y = 24

We can use either elimination or substitution method.

Using elimination method:

Multiplying the first equation by 5 and the second equation by -2, we get:

25x + 10y = 120

-4x - 10y = -48

Adding the two equations together eliminates y:

21x = 72

Solving for x:

x = 72/21 = 8/3

Substituting x back into one of the original equations and solving for y:

5(8/3) + 2y = 24

2y = 24 - 40/3

2y = 12/3

y = 6/2 = 3

Therefore, the solution to the system of equations is:

What are quadrilateral graph ?

A quadrilateral graph is a graphical representation of a quadrilateral, which is a four-sided polygon. It is a coordinate system that uses a Cartesian plane, where the x and y axes are used to plot the four vertices of the quadrilateral. The four vertices of the quadrilateral are represented by four points on the graph, and the sides of the quadrilateral are represented by the line segments connecting the points. By examining the coordinates of the vertices and the lengths of the sides, we can determine the properties of the quadrilateral, such as whether it is a parallelogram, a rectangle, a square, a trapezoid, or a kite. Quadrilateral graphs are useful tools for visualizing and analyzing quadrilaterals in geometry.

To find the area of a rectangle, we need to know the length of two adjacent sides. Let's use the points Q and R to determine the length of the rectangle.

Length of QR = √((x₂- x₁)² + (y₂ - y₁)²)

= √((-4 - 6)²+ (-3 - 3)²)

= √((-10)²+ (-6)²)

= √(100 + 36)

= √(136)

Similarly, we can find the length of ST:

Length of ST = √((x₂ - x₁)²+ (y₂ - y₁)²)

= √((9 - (-1))² + (-2 - (-8))²)

= √((10)² + (6)²)

= √(100 + 36)

= √(136)

Since QR and ST are opposite sides of the rectangle and have equal length, we know that the rectangle is indeed a rectangle. Therefore, the area of the rectangle is simply the product of the length and width:

Area of rectangle = length * width

= √(136) * √(136)

= 136 square units

Hence, the area of the rectangle is 136 square units.

air is pumped into a spherical balloon, so the balloon expands. the volume of a sphere of radius r is . if the radius of the sphere after seconds is centimeters, at what rate is air being pumped in when ?

Answers

The rate at which air is being pumped in when the radius of the sphere is 10 cm and increasing at a rate of 2 cm/s is 400π/3 cm³/s.

The volume V of a sphere with radius r is given by V = (4/3)πr³. Taking the derivative of this expression with respect to time t, we get dV/dt = 4πr²(dr/dt). This equation relates the rate of change of volume to the rate of change of the radius. We are given that the radius is increasing at a rate of 2 cm/s, so dr/dt = 2 cm/s.

At the instant when the radius is 10 cm, we can find the rate at which air is being pumped in by substituting r = 10 cm and dr/dt = 2 cm/s into the equation for dV/dt. Thus, we have dV/dt = 4π(10)²(2) = 800π cm³/s.

Therefore, when the radius of the spherical balloon is 10 cm and is increasing at a rate of 2 cm/s, the rate at which air is being pumped in is 400π/3 cubic centimeters per second.

Technology required. A regular hexagon is inscribed in a circle of radius 1 inch. What is the area of the shaded region? (Lesson 4-10)

Answers

The area of the shaded region in the given shapes is determined as 0.544 in².

What is the area of the shaded region?

The area of the shaded region is calculated by subtracting the area of the inscribed hexagon from the area of the circle.

Let's start by finding the side length of the regular hexagon inscribed in the circle.

The distance from the center of the circle to any vertex of the hexagon is equal to the radius of the circle, which is 1 inch.

In a regular hexagon, all sides are equal in length, so each side of the hexagon is also equal to 1 inch.

The area of the regular hexagon can be found using the formula:

Area of a regular hexagon = (3√3/2) x (side length)²

Substituting the side length of 1 inch, we get:

Area of regular hexagon = (3√3/2) x (1 inch)^2

= (3√3/2) square inches

= 2.598 in²

Now, to find the area of the circle, we can use the formula:

Area of a circle = π x (radius)²

Substituting the radius of 1 inch, we get:

Area of circle = π x (1 inch)²

= π square inches

= 3.142 in²

Area of the shaded region = area of circle - area of hexagon

= 3.142 in² - 2.598 in²

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using

Answers

Answer:

  PEMDAS or BIDMAS

Step-by-step explanation:

You want to know how to remember the order of operations.

Acronyms

Commonly used acronyms for the Order of Operations are ...

  PEMDAS

  BIDMAS

The letters of these stand for ...

  P, B — parentheses or brackets

  E, I — exponents or indices

  M, D — multiplication and division

  A, S — addition and subtraction

Precedence

Expressions enclosed in grouping symbols (parentheses or brackets) have the highest precedence. They are evaluated first, according to the order of operations.

Exponents (indices) are evaluated next. A sequence of exponent operations, such as a^b^c is evaluated right to left, as a^(b^c), unless parentheses modify the order.

Because exponents and indices have a higher precedence than other arithmetic operations, something like 2^3x is evaluated as (2^3)x, not 2^(3x), and √2p is (√2)p, not √(2p). It is fairly common to see a square root erroneously written as 3^1/2 = (3^1)/2 = 3/2 when 3^(1/2) = √3 is intended.

Multiplication and division have the same precedence. Even though M precedes D (or D precedes M, depending on which acronym you use), they are evaluated in order of appearance left to right. As with exponents, a common error is forgetting to put parentheses around numerators and denominators. For example, 3/2π is different from 3/(2π).

Similarly, addition and subtraction have the same precedence and are evaluated in order of appearance, left to right.

Composition

The composition (ring) operator (∘) is used to signify a sequence of functional or transformation operations. For example (f∘g)(x) is the composition of functions f and g. The functions or transformations in a composition are evaluated right to left:

  (f∘g)(x) = f(g(x))

Special notations

Operations performed on functions can be written in confusing ways. For example, ...

  [tex]y = f^{-1}(x)\qquad\text{means }x=f(y),\text{ not }y=\dfrac{1}{f(x)}[/tex]

The notation using a positive exponent stands in contrast:

  [tex]\sin^4(x)\qquad\text{usually means }(\sin(x))^4,\text{ not }\sin(\sin(\sin(\sin(x))))[/tex]

On the other hand, an exponent applied to a function name can mean recursive application of the function, as in sin²( ) = sin(sin(...)). It can also mean an n-th derivative. Context is important in such situations.

The volume of a 3-D figure with the dimensions of 3 2/3, 1 2/3, and 2 1/3

Answers

The volume of the 3-D figure is 385/81 cubic units or approximately 4.753 cubic units (rounded to three decimal places).

To find the volume of the 3-D figure, we need to multiply its three dimensions:

Volume = (3 2/3) x (1 2/3) x (2 1/3)

First, we need to convert the mixed numbers to improper fractions:

3 2/3 = 11/3, 1 2/3 = 5/3, and 2 1/3 = 7/3.

Now, we can multiply:

Volume = (11/3) x (5/3) x (7/3)

Volume = 385/81 cubic units, which is the exact answer.

If we want to approximate the answer, we can use a calculator to get:

From the information provided the measure of the angles are given as,

m ∠EFH = 71; and m ∠EFG = 142°.

Angles are measured in degrees, which is why they are called "degrees". A complete circle equals 360 degrees, so it is divided into 360 parts. Each part of the revolution is a degree. Any angle, whether acute, obtuse, reflected or right, can be measured with a protractor. Although based on right angles, we are able to distinguish acute, obtuse or reflex angles. But if we have two acute angles to measure, we cannot determine the greater angle between the two. Therefore, we need to use a protractor to measure angles accurately.

According to the Question:

It is to be noted that

m ∠GFH = m ∠EFH

⇒ m ∠EFH = 71°

1. Calcula el área total del terreno rectangular:
Área = largo x ancho
Área = 32 m x 28 m
Área = 896 m²
2. Divide el área total entre el espacio requerido por cada árbol:
Número de árboles = Área total / Espacio por árbol
Número de árboles = 896 m² / 4 m²
Número de árboles = 224

Answers

The dummy variable is used to capture the effect of the categorical variable and it has no effect on the quadratic or cubic relationship between the independent and dependent variable.

When x is a dummy variable, there will be no difference in OLS estimators between quadratic and cubic regression models. This statement is true.OLS stands for Ordinary Least Squares regression. It is a statistical method used to determine the relationship between one or more independent variables (predictors) and a dependent variable. The OLS regression method minimizes the sum of squared residuals (differences between actual and predicted values).Dummy variables are used in regression analysis to represent categorical variables.

These are represented by a variable with a binary value of 1 or 0, depending on whether the observation falls in that category or not. This variable is used to represent a categorical variable in regression analysis so that the model can capture the effect of that variable in the analysis.In regression analysis, the regression model is a function of the independent variable, also called the predictor variable, and the dependent variable. A quadratic regression model is a polynomial regression model of degree 2. It means that the relationship between the dependent and independent variable is a quadratic function.

A cubic regression model is a polynomial regression model of degree 3. It means that the relationship between the dependent and independent variable is a cubic function. When x is a dummy variable, there will be no difference in OLS estimators between quadratic and cubic regression models. The OLS estimators will be the same because the dummy variable will have no effect on the fit of the model. Hence, this statement is true.

Which vector spaces have exactly one basis?

Answers

The vector space that has exactly one basis is the trivial vector space, which is the vector space containing only the zero vector.

A basis for a vector space is a set of linearly independent vectors that span the entire space. In a non-trivial vector space (a space that contains more than just the zero vector), there are infinitely many possible bases. This is because any set of linearly independent vectors that span the space can be used as a basis.

However, in the trivial vector space, there is only one vector (the zero vector), and it is linearly independent of itself. Therefore, the trivial vector space has exactly one basis, which is the set containing only the zero vector. Any other set of vectors in the trivial vector space is linearly dependent, and therefore cannot be used as a basis.

Multiply 4 times (x + 2).

Answers

Answer:

4x + 8

Step-by-step explanation:

You multiple 4 by x, and then 4 by 2, and add them together

Step 1 write 4(x+2)
Step 2 multiply x by 4 and 2 by 4 =4x+8
Write therefore 4 times (x + 2 ) is 4x +8

A concrete pillar has the shape of a cylinder. It has a diameter of 6 meters and a height of 7 meters. If concrete costs $116 per cubic meter, how much did the concrete cost for the pillar? For your calculations, do not round any intermediate steps, and use the button on a calculator. Round your answer to the nearest cent.​

Answers

The volume of the cylinder-shaped pillar is given by the formula:

V = πr²h

where r is the radius of the base (which is half the diameter), and h is the height. So, for this pillar:

r = 6 meters / 2 = 3 meters
h = 7 meters

Substituting these values, we get:

V = π(3 meters)²(7 meters)
V = π(9 meters²)(7 meters)
V = π(81 meters³)

Using the value of π = 3.14159265359 (rounded to 11 decimal places), we can calculate the volume:

V ≈ 2,251.94671058 cubic meters

Multiplying the volume by the cost per cubic meter, we get the total cost of the concrete:

Total Cost = V × Cost per cubic meter
Total Cost = 2,251.94671058 cubic meters × $116/cubic meter
Total Cost ≈ $261,372.98

Rounding this to the nearest cent, we get the final answer:

The concrete cost for the pillar is approximately $261,372.98

If the gymnasium is 30 meters long and 16 meters wide what will the distance be between opposite corners

Answers

To find the distance between opposite corners of a rectangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs (the two shorter sides) is equal to the square of the length of the hypotenuse (the longest side).

In this case, the gymnasium is a rectangle, so we can use the Pythagorean theorem to find the distance between opposite corners:

a = 30 meters (length of the rectangle)
b = 16 meters (width of the rectangle)
c = ? (distance between opposite corners)

c² = a² + b²
c² = (30 meters)² + (16 meters)²
c² = 900 + 256
c² = 1156

Taking the square root of both sides to solve for c:
c = √1156
c = 34

Therefore, the distance between opposite corners of the gymnasium is approximately 34 meters.
