The term best describes point X is option A. Centroid.

The point of intersection of a triangle's medians is its centroid (the lines joining each vertex with the midpoint of the opposite side).

If the surface is plane triangle approximately and mass is uniformly distributed, then its center of mass will lie on the centroid of that triangle.

If the triangle has its vertices as   [tex](x_1, y_1), (x_2, y_2) , \: (x_3, y_3)[/tex]then the coordinates of the centroid of that triangle is given by:

[tex](x,y) = \left( \dfrac{x_1 + x_2 + x_3}{3} + \dfrac{y_1 + y_2 + y_3}{3} \right)[/tex]

A triangle is a three-edged polygon with three vertices. The length of a side of the regular hexagon is √24 inches.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angle of a triangle is always equal to 180°.

Given the perimeter of the equilateral triangle is 36 inches, therefore, the length of the side of the equilateral triangle is 12 inches. Now, the area of the equilateral triangle is,

Area of the equilateral triangle = (√3)/4 a²

                                                   = (√3)/4 × (12)²

                                                   = (36√3) inches²

Since the area of the equilateral triangle is equal to the area of the hexagon , therefore we can write,

Area of equilateral triangle = Area of Hexagon

(36√3) = (3√3)/2× a²

a² = 24

a = √24 inches

Hence, the length of a side of the regular hexagon is √24 inches.

The distance from his home to his work place is 118.125 miles

He drove from home to work at an average speed of 45 mph. Therefore,

speed = 45 mph

let

time = x

speed = distance / time

distance = 45x

His return trip home took 45 minutes longer because he could only drive at 35 mph. Therefore,

45 minutes = 0.75 hours

distance = 35(x + 0.75)

distance = 35x + 26.25

Therefore,

45x = 35x + 26.25

45x - 35x = 26.25

10x = 26.25

x = 26.25 / 10

x = 2.625

Answer:

No.

Step-by-step explanation:

If you look at the y values, they do not have a constant rate of change. The numbers in the row for y: 3+1 is 4. 4+1 is 5. 5+7 is 12 .12+19 is 31. 31+ 37 is 68. So, as you can see, the rates at which each number changes are not constant. Therefore, the table does not represent a linear function.

The first step to solving almost any problem is to understand what the question is asking and what is given to us in order for us to solve for the question.  In this problem, we are given a graph and asked two questions.  One being what the coordinates of the vertex are and whether this parabola has a maximum or a minimum.  

Let's define what a vertex, maximum, and minimums are.

Now, looking at our problem we can see that our vertex is at the bottom therefore it would classify as a minimum.  Now that we know we have a minimum vertex, let us determine what the actual coordinates of the vertex are.  

We can see that we travel -3 in the x direction and -5 in the y direction which means that the coordinate for our vertex is (-3, -5) where the first number represents the x-value and the second number represents the y-value.

Answer:

(-3, -5)

Step-by-step explanation:

Here the vertex is also the minimum value; its x-coordinate is -3 and its y-coordinate is -5.  Thus, the vertex is at (-3, -5).  As stated above, this is the minimum value of the function.

The table of values of the function y = 2x^2 is:

x  0   1   2   3   4

y  0   2  8   18   32

The equation of the function is given as:

y = 2x^2

When x= 0, we have

y = 2 * 0^2 = 0

When x= 1, we have

y = 2 * 1^2 = 2

When x= 2, we have

y = 2 * 2^2 = 8

When x= 3, we have

y = 2 * 3^2 = 18

When x= 4, we have

y = 2 * 4^2 = 32

So, the table of values is:

x  0   1   2   3   4

y  0   2  8   18   32

The required compass heading of the submarine is 341 degrees.

To find the compass heading of the submarine, we need to determine the angle it makes in the north direction, clockwise.

Since the submarine is traveling 19 degrees west of north, the compass heading can be calculated as follows:

Compass Heading = 360 degrees - (Angle west of North)

Compass Heading = 360 degrees - 19 degrees

Compass Heading = 341 degrees

Problem 1

Any pair of equilateral triangles are always similar triangles. We can use the SSS (side side side) similarity theorem to prove this. One triangle is an enlarged copy of the other, or a shrunken reduced copy.

The rectangle is NOT similar to the square. They are different shapes. Similar figures are figures that are the same shape, but different sizes.

==========================================================

Problem 2

horizontal/vertical = horizontal/vertical

24/x = 6/5

24*5 = 6x

120 = 6x

x = 120/6

x = 20

Answer: The flagpole is 20 ft high (about 2 stories tall)

==========================================================

Problem 3

The formula to use is [tex]z = \sqrt{x*y}[/tex]

z = geometric mean of x and y

We multiply the numbers and take the square root. This only works for two values at a time. The geometric mean of three numbers will involve the cube root. Four numbers involves the 4th root, and so on.

==========================================================

Problem 4

For each figure, the y is the altitude and can be determined using the geometric mean formula.

The decimal values are approximate.

==========================================================

Problem 5

For 45-45-90 triangles, we divide the hypotenuse over sqrt(2) to find the leg length.

For the first triangle in the first row, we have y = 18/sqrt(2) = 9*sqrt(2) after rationalizing the denominator. Multiply top and bottom by sqrt(2).

Take this process in reverse to determine the hypotenuse if you know the leg length. This explains why the hypotenuse is 3.2*sqrt(2) for the second triangle in the first row.

-------------------

For 30-60-90 triangles, we go from the short leg x to the hypotenuse 2x.

Double the short leg to get the hypotenuse.

2x = 36

x = 36/2

x = 18

This is for the first triangle in the bottom row.

For the other triangle in this bottom row, we have a long leg of 4*sqrt(3). This must mean the short leg is exactly 4 units long. Therefore, the hypotenuse is 2*4 = 8 units long.

    y = mx + c     ............(i)

where, m is slope of line and c is y-intercept.

Given equation of line;

      g(x) = y = -6x + 3

Mike's claim that (5,28.6) is a point on the exponential function g(x) is incorrect

The points are given as:

(3,6.5) and (4,17.55)

Calculate the rate of change using:

r = y4/y3

This means that:

r = 17.55/6.5

r = 2.7

So, the next point on the graph is:

Next point = 2.7 * y4

Substitute 17.55 for y4

Next point = 2.7 * 17.55

Evaluate

Next point = 47.39

This means that the next point on the graph is (5,47.99)

Hence, Mike's claim that (5,28.6) is a point on the exponential function g(x) is incorrect
