👉 Learn how to find the distance between two points. The distance between two points is the length of the line joining the two points in the coordinate plane. To find the distance between two points in the coordinate plane, we make use...

This video introduces the Bones and Muscles series. This series explores the characteristics of the skeletal and muscular systems, discusses the different types of muscles and joints in the human body, and gives examples of how we use...

This is a lecture video that explains how to calculate the range from a data set. The video covers examples with both numerical and frequency table data, as well as group frequency tables. The presenter emphasizes the importance of...

In this video, a teacher discusses how to use the distance formula to determine if points are collinear, recognize different types of triangles, including right-angled triangles, and determine if given coordinates form a square. The...

👉 Learn how to find the missing measure of a segment. A segment is a line that has two endpoints. A segment can be subdivided into several portions. The length of the segment is the sum of all the sub-divisions of the segment. Thus, when...

This video provides an overview of satellites, explaining that they are objects that orbit around planets or stars. It distinguishes between natural satellites, such as moons, and artificial satellites, which are man-made. The video...

👉 Learn how to find the distance between two points. The distance between two points is the length of the line joining the two points in the coordinate plane. To find the distance between two points in the coordinate plane, we make use...

Learn all about hyperbolas. A hyperbola is a conic section with two fixed points called the foci such that the difference between the distances of any point on the hyperbola from the two foci is equal to the distance between the two...

Scientists have discovered that a mysterious pressure dubbed "dark energy" makes up about 68 percent of the total energy content of the cosmos, but so far we don't know much more about it. Exploring the...

👉 Learn how to find the midpoint between two points. The midpoint between two points is the point halfway the line joining two given points in the coordinate plane. To find the midpoint between two points we add the x-coordinates of the...

👉 You will learn how to multiply integers from one digit to multiple digits. When multiplying it is important to understand that multiplication is just repeated addition. However with multi-digit numbers we will follow a step by step...

Learn all about ellipses for conic sections. We will discuss all the essential definitions such as center,co ver foci, vertices, co-vertices, major axis and minor axis. We will also discuss the essential processes such as how to graph...

In this short math video we will answer a standardized math test question where we show our understanding of line plots. We will first recognize that each x on the line plot represents one piece of data. We will eliminate the answer...

Retired NASA astronaut John Grunsfeld hosts this six-part mini-series about the tools used on the Hubble Space Telescope servicing missions. Hubble was uniquely designed to be serviced in space so that components could be...
