What’s the correct answer?

Answer: B

Step-by-step explanation: Adjacency Matrix is a square matrix representing a simple graph with 0 or 1 according to the condition given.

In this diagram, 0 corresponds to no connection between airports and 1 corresponds to connections between airports.

In other words, analysing the image, we see that:

1) Albany just have connection with Atlanta, so in the position of line Albany with column At, it must be a 1. The other columns, there are 0.

The Line for Albany in the matrix will be: [0 1 0 0 0 0]

2) Atlanta has connections with Albany, Dalton, Macon and Augusta. So corresponding position (line and column) must be 1. The only two airports Atlanta doesn't have connection with its own and Waycross, so at the corresponding column and line, it is written 0.

The line for Atlanta in the matrix is [1 0 1 1 1 0]

3) Augusta: connections with Atlanta, Macon, Waycross. At those positions, it will be written 1. At positions related to itself, Albany and Dalton is 0.

The line in the matrix will be [0 1 0 0 1 1]

4) Dalton: connection with Atlanta only. That position will be 1 while the others will be 0.

The line is [0 1 0 0 0 0]

5) Macon: connections with Atlanta, Augusta and Waycon: those positions will have 1 and the other 0.

The line is [0 1 1 0 0 1]

6) Waycross: connections with Macon and Augusta. Those positions will be 1 and the others 0.

The line is [0 0 1 0 1 0]

In conclusion, the adjacency matrix matching the scenario is

[tex]A=\left[\begin{array}{cccccc}0&1&0&0&0&0\\1&0&1&1&1&0\\0&1&0&0&1&1\\0&1&0&0&0&0\\0&1&1&0&0&1\\0&0&1&0&1&0\end{array}\right][/tex]

Answer:

When the number of hours t is less than 5 hours, Company A is cheaper than Company B

Step-by-step explanation:

Let the number of hours be represented by t

For Company A

Company A charges $45 per hour and a $150 equipment fee.

150 + 45t

For Company B

Company B charges $35 per hour and a $200 equipment fee.

200 + 35t

Write an equation for each situation, in terms of t,t, and determine

The interval of hours,t, for which Company A is cheaper than Company B is given as:

Company A < Company B

Hence:

150 + 45t < 200 + 35t

Collecting like terms

45t - 35t < 200 - 150

10t < 50

t< 50/10

t < 5

When the number of hours t is less than 5 hours, Company A is cheaper than Company B

Answer: x = -7 and x = 2

(x,y)

look at the 2 that y=1

Using the graph the input values that correspond with f(x) = 1 is x = -7 and x = 2.

A graph is a visual representation of data or information, often used to show the relationship between variables.

The given graph is of a function f(x) which is shown on the y-axis. The horizontal line at y = 1 is also shown on the graph.

To find the input values that correspond with f(x) = 1, we need to look for the points where the function f(x) intersects with the horizontal line y = 1.

From the graph, we can see that there are two such points:

One point is where the function intersects the line at x = -7. At this point, f(x) = 1, since the function value is equal to the y-coordinate of the intersection point.

The other point is where the function intersects the line at x = 2. At this point, f(x) = 1 as well.

Therefore, the input values that correspond with f(x) = 1 are x = -7 and x = 2. So the answer is "x = -7 and x = 2".

Answer:

y=4x-3

Step-by-step explanation:

We're given that the equation is linear (a line), so it must be in the form y=mx+b. We're also given that it contains the points (0,-3) and (1,1).

Plugging the values of the x and y coordinates in that first point, we get the equation -3=m*0+b, simplifying to -3=b. Therefore, the b-value is -3.

Next, we can plug in the values from the second point to get the equation 1=m*1-3, which simplifies to 1=m-3. Adding 3 to both sides, we get m=4. Therefore, the equation of the line is y=4x-3.

Note that -3 is the value where the line intercepts the y-axis, which means -3 is known as the y-intercept. The value of b is always the y-intercept.

Answer:

(5,4) and (3,4)

Step-by-step explanation:

A line segment has 2 end points which can be denoted as:

[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

When this line segment intersects at y.

This means that the coordinate on the y axis is the same at both end points

i.e.

[tex]y_1 = y_2 = y[/tex]

[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] becomes [tex](x_1,y)[/tex] and [tex](x_2,y)[/tex]

x1 and x2 can be any value but the y value must remain unchanged

Using the above analysis, a possible coordinate is:

[tex](5,4)[/tex] and [tex](3,4)[/tex]

Note that there are as many answers as possible as long as the coordinate pair satisfy is of the form [tex](x_1,y)[/tex] and [tex](x_2,y)[/tex]

Take for instance, another possible pair is:

[tex](1,-3)[/tex] and [tex](0,-3)[/tex]

Step-by-step explanation:

-3 (4 - 3x) = 5x + 16

* multiple -3 to each number in the parenthesis

-12 + 9x = 5x + 16

* add 12 to both sides to cancel it and combine like terms on the other side

9x = 5x + 28

* subtract 5x from both sides to cancel it out and combine like terms

4x = 28

* divide 4 from both sides to get x alone

The width of a similar photo comes to be 2 inches.

Width of original photo = 4 inches

Height of the original photo = 6 inches

Height of the scaled photo = 3 inches

A scale factor is a number that multiplies (“scales”) a quantity.

Scale factor = height of scaled photo/ height of the original photo

Scale factor= 3/6 = 1/2

So, the width of the scaled photo = scale factor * width of the original photo

The width of the scaled photo = (1/2)*4

The width of the scaled photo =2 inches.

Therefore, the width of a similar photo comes to be 2 inches.

The directional bearing of the boat is N 30º E

Step-by-step explanation:

Let [tex]\vec v = (25, 25\sqrt{3})[/tex], where [tex]\vec v[/tex] is the vector velocity. Given that such vector is represented in rectangular, a positive value in the first component is the value of the vector in the east direction, whereas a positive value in the second component is in the north direction. The directional bearing of the boat ([tex]\theta[/tex]), measured in sexagesimal degrees, is determined by trigonometrical means:

[tex]\theta = \tan^{-1}\frac{v_{y}}{v_{x}}[/tex] (1)

If we know that [tex]v_{x} = 25[/tex] and [tex]v_{y} = 25\sqrt{3}[/tex], then the directional bearing of the boat is:

[tex]\theta = \tan^{-1} \sqrt{3}[/tex]

[tex]\theta = 60^{\circ}[/tex]

In consequence, we conclude that the direction bearing of the boat is 30 degrees to the East from the North (N 30º E).
