x intercept is x = -12

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C. A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

x = 4y - 12

y = 0

What is union and intersection of sets?
The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets

The intersection of two sets is a new set that contains all of the elements that are in both sets

Given data ,

Let the equation be x

x = A ∩ ( B' ∪ C' )

Now , from Distributive law of set

A ∩ (B ∪ C) = (A ∩ B) ∪ (A ∩ C)

And , ( A ∩ B' ) = A - B

So , substituting the formulas in the equation , we get

x = A ∩ ( B' ∪ C' )

x = ( A ∩ B' ) ∪ ( A ∩ C' )

x = ( A - B ) ∪ ( A - C )

Hence , the solution is TRUE

Answer:

300

Step-by-step explanation:

Given:

100$ before passengers. 25 is the price per person. 225 for 5 people to fly.

One variable can be used to solve a linear equation by moving the variables to one side of the problem and the numerical component to the other. As an example, the equation x - 1 = 5 - 2x can be solved by moving the numerical components to the equation's right side while leaving the variables on the left. Consequently, we get x + 2x = 5 + 1. 3x = 6 as a result. Consequently, x = 2. A linear equation with two variables has the formula Ax + By + C = 0, where A and B are the coefficients, C is a constant term, and the two variables, x and y, each have a degree of one. 7x + 9y + 4 = 0, for instance, is a two-variable linear equation.

The dilation of the geometric figure with a scale factor of 1/4 about the origin is: J' (-0.5, -0.25), K' (-0.25, 1), L' (0.75, 0.25), M' (0.75, -0.75).

Dilation simply refers to a type of transformation which changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

Note: Each interval on this graph represents 1 unit.

For the given coordinates, the dilation with a scale factor of 1/4 about the origin or center of dilation (0, 0) should be calculated as follows:

Point J (-2, -1) → Point J' (-2 × 1/4, -1 × 1/4) = Point J' (-0.5, -0.25).

Point K (-1, 4) → Point K' (-1 × 1/4, 4 × 1/4) = Point K' (-0.25, 1).

Point L (3, 1) → Point L' (3 × 1/4, 1 × 1/4) = Point L' (0.75, 0.25).

Point M 3, -3) → Point M' (3 × 1/4, -3 × 1/4) = Point M' (0.75, -0.75).

The value for h(-1) is 4

The value for  h'(-1) is 1

Given the tangent line to the graph of y=h(x) at the point (-1,4) passes through (3,6), to get h(-1) and h'(-1), we should calculate the following:

Gradient of the tangent line:

Gradient=change in y axis/change in x axis=Δy/Δx

Using the x and y coordinates (-1,4) and (3,6)

Gradient=(6-4)/(3--1)

             =2/4

            =1/2

Gradient=1/2 or 0.5

Equation of the tangent line:

This should be in the form of y=mx+c, where m is the gradient of the line

We use the gradient and one of the x and y coordinates get the equation of the tangent line

Gradient=change in y axis/change in x axis=Δy/Δx, and gradient was found as 1/2

Δy/Δx=1/2

(y-4)/(x--1)=1/2

(y-4)/(x+1)=1/2

2y-8=x+1

y=(1/2)x+4.5

Equation of the tangent line is y=(1/2)x+4.5 or y=0.5x+4.5

And y=h(x)

So, h(x)=0.5x+4.5

Calculate h(-1), here x=-1:

h(x)=0.5x+4.5

h(-1)=(0.5*-1)+4.5

      =4

h(-1)=4

Calculate h'(-1), x=-1:

Here we get the derivative of the equation of the tangent line h(x)=0.5x+4.5,

h'(x)=0.5x^0+0

h'(-1)=1+0

h'(-1)=1

Answer:

(a) The profit function is P(x) = 89x - 90,000.

(b) The company's profit at x=23,000 is 1,957,000.

Step-by-step explanation:

Given,

The cost function of the company is C(x)=90,000 +42x and

The revenue function is R(x) = 47x

where x is the number of radios.

(a)

The company's profit function, P, is from producing and selling x radios is

The formula for profit:

Profit (P) = Revenue (R) - Cost (C)

P = R - C

P = 47x - 90,000 + 42x

P = (47x + 42x) - 90,000

P = 89x - 90,000

For (a), The company's profit function, P, from producing and selling x radios is P = 89x - 90,000

(b)

The radios produced and sold are 23,000

So, x = 23,000

putting x value in the profit function, P

P = 89x - 90,000

P = 89 x 23,000 - 90,000

P =  2,047,000- 90,000

P = 1,957,000

For (b), the company's profit at x = 23,000 is 1,957,000.

The integer n = 25 is the only value so that the sector AOB is greater than 20 and less than 30.

In this problem we find the sector generated by line segments OA and OB, where O is the center of the circle and the points A and B are on the circle:

20 < 360 / n < 30

20 · n < 360 < 30 · n

First, we determine the factorial decomposition of 360:

360 = 2³ × 3² × 5

Second, find the value of n associated to each limit of the inequality:

Lower limit

360 = (2² × 5) × (2 × 3²)

360 = 20 × 18

n = 18

Upper limit

360 = (2 × 3 × 5) × (2² × 3)

360 = 30 × 12

n = 12

Third, find the values that are between 12 and 18:

x = 2³ × 3

x = 24

n = 360 / 24

n = 15

The time taken by the ship to reach that distance will be 6 years.

Time is defined as the total duration of motion of an object in order to achieve some specific distance.

Given is an extrasolar which is observed at a distance of 4.2 x 10⁹ kilometers away. A group of scientist has designed a spaceship that can travel at speed of 7 x 10⁸ Kilometers/year.

Now, in order to calculate the time, we can use the simple formula as -

Time = distance / speed

Substituting the values -

Time [t] = (4.2 x 10⁹) / (7 x 10⁸)

Time [t] = 0.6 x 10

Time [t] = 6 years

Therefore, the time taken by the ship to reach that distance will be 6 years.

What is Mean Absolute Deviation?

The average distance between each data value and the mean is known as the mean absolute deviation (MAD) of a data set. A measure of variance in a data set is the mean absolute deviation.

The mean of the data will be = 96+38+162+65+178+112+57+143+135+104+88+22/12

= 1200/12

The mean would be 100

|data - mean value| = 96-100 = 4

38-100 = 62

162-100 = 62

65-100 = 35

178-100 = 78

112-100 = 12

57-100 = 43

143-100 = 43

135-100= 35

104-100 = 4

88-100 = 12

22-100 = 78

Now, sum of |data - mean values| = 468

The mean absolute deviation:

                                       =  sum of |data - mean values| / number of values

                                       = 468 / 12
