2. Match the picture of the triangle to the correct name for its center. 1. Orthocenter 2. Incenter 3. Circumcenter 4. Centroid
Centroid, Incenter, Circumcenter,Orthocenter are the name of its center
Explain centers are defined for a triangle?OrthocenterThe orthocenter is the intersection of the altitudes of the triangle. Each altitude intersects a vertex and is orthogonal to the opposite side. The orthocenter will not be inside the triangle if the triangle is obtuse. The orthocenter of a right triangle is the right-angle vertex.IncenterThe incenter is the center of an inscribed circle of a triangle. The incenter must be the same distance from each side, so will be at the point of intersection of the angle bisectors. It always lies inside the triangle.CentroidThe centroid is the "center of gravity" of the triangle, the point at which the triangle could be balanced. Each median divides the triangle into two equal areas, so the intersection of medians marks a spot with equal area (weight) in every pair of opposite directions.CircumcenterThe circumcenter is the center of a circle that circumscribes the triangle. It is equidistant from the three vertices, so lies on the intersection of the perpendicular bisectors of the sides. It will lie outside the triangle for obtuse triangles. It is the midpoint of the hypotenuse of a right triangle.

Two parallel train tracks, S and T, are cut by another train track, U. The train track U creates an interior angle of 101 with track S.
How can you use this information to solve for the measure of the same side interior angle made by track T and track U?
The measure of the same side interior angle made by track T and track U is; 79 degrees
How to find same side interior angles?Same side interior angles are defined as two angles that are on the interior of or between the two lines and particularly on the same side of the transversal. The same-side interior angles usually sum up to 180 degrees. Finally, when two parallel lines are intersected by a transversal line they will form 4 interior angles.
Now, we are told that the train track U creates an interior angle of 101 with track S.
Thus, using same side interior angles definition, the measure of the same side interior angle made by track T and track U is;
same side interior angle = 180 - 101
= 79 degrees

An inflatable ball can be modeled as a hollow sphere. Miguel
measures the outer diameter of the ball to be 50 cm. If the
material that makes up the ball has a thickness of 1.25 cm, find
the total volume of material that makes up the ball. Round your
answer to the nearest hundredth if necessary. (Note: diagram is
not drawn to scale.)
we can find the total volume of material that makes up the ball by subtracting the volume of the hollow space from the volume of the sphere:
V = 20,834 cm^3 - 19,848.44 cm^3
= 985.56 cm^3
what is volume?Volume is a measure of the amount of space occupied by an object or a substance. It is typically measured in units such as cubic meters (m^3), cubic centimeters (cm^3), or cubic feet (ft^3).
What is diameter?Diameter is a measure of the distance across the widest part of a circular object, such as a circle or a sphere. It is equal to twice the radius of the object and is typically measured in units such as millimeters (mm), centimeters (cm), or inches (in). It is a linear measurement.
To find the total volume of material that makes up the ball, we need to find the volume of the sphere and then subtract the volume of the hollow space in the center.
We can begin by calculating the volume of the sphere using the formula for the volume of a sphere:
V = (4/3) * pi * r^3
Where V is the volume, pi is approximately 3.14, and r is the radius of the sphere.
The outer diameter of the ball is 50 cm, so the radius of the sphere is (50/2) = 25 cm.
Substituting these values into the formula, we get:
V = (4/3) * 3.14 * (25 cm)^3
= (4/3) * 3.14 * 15,625 cm^3
= 20,834 cm^3
Next, we need to find the volume of the hollow space in the center of the ball, which is the same as the volume of a smaller sphere with a radius of (25 cm - 1.25 cm) = 23.75 cm.
So the volume of the hollow space is :
V = (4/3) * pi * (23.75 cm)^3
= (4/3) * 3.14 * (23.75 cm)^3
= 19,848.44 cm^3
Finally, we can find the total volume of material that makes up the ball by subtracting the volume of the hollow space from the volume of the sphere:
V = 20,834 cm^3 - 19,848.44 cm^3
= 985.56 cm^3

Answer: The interval in which the greatest number of scores would occur is between (20 - 2.6) and (20 + 2.6), which is approximately 17.4 and 22.6 respectively. This interval is also known as the "bell curve" or the "normal distribution curve" and it is centered at the mean (20) and covers approximately 68% of all possible scores. Most of the data points would fall within one standard deviation of the mean, hence the greatest number of scores would occur in this interval.

For the given equation, find the values of a, b, and c, determine the direction in which the parabola opens, and determine the y-intercept. Decide which table best illustrates these values for the equation: f (x) = negative 9 x squared + 7 x.
Examining the function -9x² + 7x the parabolic curve is opening downwards and the y intercept is 7/9 and 0
Where to look for the y interceptsThe sign of the x2 coefficient determines whether a parabolic curve opens upward or downward in this scenario.
In this function, the coefficient of x2 is a and is -9.
Rising downwards results from a negative coefficient, while opening upwards from a positive coefficient
The intercept of y
-9x² + 7x = 0
x(-9x + 7) = 0
x = 0
-9x + 7 = 0
-9x = -7
x = 7/9

Matrix C has 3 rows and 2 columns. The size or dimensions can be written in shorthand as 3x2.
Matrix D has dimensions 2x1, aka 2 rows and 1 column.
-------------------
Write "3x2" and "2x1" side by side in that exact order.
Notice the inner '2's match up. This is important. We need the inner numbers to match so that matrix multiplication is possible. The outer values '3' and '1' will help form the dimensions of the final answer matrix. The final answer matrix will have dimensions 3x1
Luckily we don't need to compute the value of CD. We just need to use the justification mentioned in the previous paragraphs to conclude that matrix CD is possible.

How do you draw a perpendicular line in Class 7?
A perpendicular line is one that is perpendicular or 90 degrees to another line. In order to draw a perpendicular line in Class 7, it is important to understand the formula and calculation associated with it.
The formula associated with perpendicular lines is that the product of the slope of the two lines must be equal to -1. This means that if one line has a slope of m1, then the slope of the perpendicular line must be -1/m1.
In order to calculate the slope of a line, we must use the formula m = (y2-y1)/(x2-x1), where m is the slope, (x1,y1) is the first point, and (x2,y2) is the second point. With this information, we can use the formula to calculate the slope of the line we want to draw a perpendicular line to, and then use the formula m = -1/m1 to calculate the slope of the perpendicular line.
Finally, with the slope of the perpendicular line, we can use the point-slope form of the equation of a line, y-y1=m(x-x1), to plot the equation of the line and draw it on the graph. This formula can be used to draw a perpendicular line in Class 7.

What are 2 types of coordinate reference systems?
The two main types of coordinate systems used in mathematics and physics are Cartesian and Polar Coordinates.
What is coordinates system?A coordinate system is a system used to identify and locate a point in space. It is the basis for maps, navigation and surveying. Coordinate systems can be two-dimensional or three-dimensional, and can use a variety of units such as latitude, longitude, and feet. Coordinate systems are used in a variety of fields such as engineering, architecture, geology, and navigation. Coordinate systems help to identify and locate points in space and are essential for charting and mapping the physical world.
Cartesian Coordinates, named after the French mathematician and philosopher René Descartes, use a two-dimensional plane to represent points with an x-axis and a y-axis. These coordinates are expressed as ordered pairs (x,y) and represent points in relation to the origin (0,0). This can be used to plot graphs and equations, and is the most commonly used coordinate system.
Polar Coordinates are based on a two-dimensional plane centered on a pole. Points are expressed as ordered pairs (r,θ) where r is the distance from the pole and θ is the angle from the polar axis. This coordinate system is useful for finding distances and angles in a circle. It is used frequently in physics and astronomy.
