true or false: the highest weight edge in a graph will never be in an mst. if true, prove it. if false, show an example in which it is included.
False. Consider a graph with 4 vertices, where there is an edge of weight 8 between the two farthest vertices, and an edge of weight 10 between the two closest vertices.
The highest weight edge (10) would be included in the MST, as it is the only connection between the two closest vertices.The definition of a minimum spanning tree states that it is a subset of edges of a graph that connect all of the vertices without forming any cycles, and with the minimum total weight. If a graph contains an edge with the highest weight, it may still be included in the MST if it is the only connection between two vertices. To illustrate this, consider a graph with 4 vertices, where there is an edge of weight 8 between the two farthest vertices, and an edge of weight 10 between the two closest vertices. In this case, the highest weight edge (10) would be included in the MST, as it is the only connection between the two closest vertices, and thus the minimum total weight is achieved.

The measure of z on the right triangle shown at the end of the answer is given as follows:
z = square root of 80.
How to obtain the measure of z?To obtain the measure of z, the first step is obtaining the measure of y, which is obtained using the geometric mean property, as follows:
y = square root of (16 x 4) = square root of 64 = 8.
The Pythagorean Theorem states that the measure of the hypotenuse squared is equals to the sum of the squares of the measures of each side.
For the smaller right triangle, we have that:
The two legs have measures of 4 and 8.The hypotenuse has a measure of z.Then the length of the hypotenuse z is obtained applying the Pythagorean Theorem as follows:
z² = 4² + 8²

g(x) = 64(0.5x)
The values of a function represent the actual values of the function.
X has a value of 5.
Explain about the functions?
An expression, rule, or law that specifies the relationship between two variables is known as a function in mathematics (the dependent variable). Functions abound in mathematics, and the sciences rely on them to build physical links.
If any vertical line drawn through the graph may only cross it once, it is a function. If there are any points on the graph where a vertical line might cross it twice or more, the graph is not a function.
In a spreadsheet program, a function is a programmed calculation, whereas an Excel formula is an equation that the user has developed.
The functions are
f(x) = 2.5x - 10.5
g(x) = 64(0.5x)
x = 3 to 5 results in:
f(3) = 2.5(3) - 10.5 = -3
f(4) = 2.5(4) - 10.5 = -0.5
f(5) = 2.5(5) - 10.5 = -2
x = 3 to 5 results in:
g(3) = 64(0.5³)= 8
g(4) = 64(0.5x4) = 4

through:(0,-3), slope=7/2
The equation of the line would be 7x - 2y = 6.
What is the slope-point form of the line?
For the line having slope "m" and the point (x1, y1) the equation of the line passing through the point (x1, y1) having slope 'm' would be
y - y1 = m(x - x1)
The required line passes through (0, -3) and the slope is 7/2.
By using the slope-point form of the line, we get
y - (-3) = (7/2)(x-0)
y + 3 = 7/2x
2y + 6 = 7x
7x - 2y = 6
Hence, the equation of the line would be 7x - 2y = 6.

What are similar triangles?
If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as ΔCAE
Now , the second triangle is ΔCBD
And , ΔCAE ≅ ΔCBD
So , Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
And ,
CE / CD = CA / CB
Substituting the values in the equation , we get

Determine if the lines are parallel, perpendicular, neither or coinsiding..
y=-3x+7
y = 3x - 7
A Perpendicular
B neither
C Parallel
D Coinciding
Answer:
neither
Step-by-step explanation:
The slopes are neither equal nor negative reciprocal.
Answer:
B
Step-by-step explanation:
The lines are B. Neither.
To determine whether two lines are parallel, perpendicular, neither, or coinciding, we can look at their slope. The slope of a line is a measure of how steep the line is. It is calculated by taking the difference in the y-coordinates of two points on the line, and dividing it by the difference in the x-coordinates of those points.
In this case, the two lines have the equations y = -3x + 7 and y = 3x - 7. To find their slopes, we can plug in the coordinates of two points on each line, and then calculate the slope using the formula mentioned above.
For the first line, we can use the points (0, 7) and (1, 4) to calculate the slope:
Slope = (4 - 7) / (1 - 0) = -3
For the second line, we can use the points (0, -7) and (1, -4) to calculate the slope:
Slope = (-4 - (-7)) / (1 - 0) = 3
Since the slopes of the two lines are the opposite of each other (i.e. one is positive and the other is negative), the lines are not perpendicular or coinciding to each other. This means that they do intersect at a right angle, and are not parallel or coinciding. Therefore, the correct answer is B, neither.

use the given graph of the function to find the x-values for which f is not differentiable.
In the given graph of the function, the function is not differentiable for values of x is -1 and 2.
Therefore the answer is -1 and 2.
In the given graph we can observe that the graph is not continuous at x = -1 and also that there is a sharp corner at x = 2.
The condition for differentiability of a function is that it should be continuous. Also a function is not differentiable at a corner point as the slope is not defined at that particular point.
Therefore, the values of x at which the given graph is not differentiable is x = -1 and x = 2.

In the △IGH, the measurement of the angles are m∠G = 114°, m∠H = 49°, and m∠I = 17°.
What is an angle?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
Given that,
m∠G = (7x - 5)°, m∠H = (3x - 2)°, and m∠I = x°.
The sum of interior angles of a triangle is 180°.
Therefore,
m∠G + m∠H + m∠I = 180°
Putting m∠G = (7x - 5)°, m∠H = (3x - 2)°, and m∠I = x°:
(7x - 5)° + (3x - 2)° + x° = 180°
Combine like terms:
(7x + 3x + x) - (5 + 2) =180
11x - 7 = 180
Add 7 on both sides:
11x = 187
Divide both sides by 11:
x = 187/11
x = 17
Now putting x = 17 in m∠G = (7x - 5)°, m∠H = (3x - 2)°, and m∠I = x°:
m∠G = (7×17 - 5)° = 114°
, m∠H = (3×17 - 2)° = 49°

The ratio of a to b is 3:5. The difference between angle a and b is 36°. What is the size of angle C
No links please it’s been bugging me for 30 minutes
Answer:
The ratio of a to b is 3:5, which means that the value of a is 3/8 of the value of b. This means that if the difference between the angles a and b is 36°, then the size of angle a is 3/8 * 36° = 9°.
To find the size of angle C, we need to add the size of angle a to the size of angle b. Since the size of angle a is 9° and the difference between the sizes of angles a and b is 36°, the size of angle b is 36° + 9° = 45°.
The size of angle C is the sum of the sizes of angles a and b, so the size of angle C is 9° + 45° = 54°. Therefore, the size of angle C is 54°.
