Changing from standard form to vertex form-Quadratic EquationsStandard form = ax^2 +bx+c=yVertex form = a(x-h)^2 +k =yThe video gives step by step directions for converting from standard to vertex form.
The video reviews how to find the radius of a sphere given the volume.For example, find the radius of a sphere with a volume of 72 meters squared.The volume formula is 4/3 pi r cubed.In order to solve for the radius you have to undo the formula.
In this video I show how to subtract integers by using counters. The counters help you visualize the process of subtracting integers. If you struggle with remembering how to subtract positive and negative numbers,this video will help.
In this video you will learn how to calculate percentage change between two numbers.The formula you can use is new value minus the old value/old value times 100A positive number will be a percent increase, and a negative number will be a percent decrease.
In this video you will learn how to create a frequency table for a data set that has a wide range.The key to the frequency table is to create intervals for your frequency table.
In this video you will learn the basics of analyzing data using center, spread, and shape.Measures of center include mean,median,and mode.Measures of spread include range, and interquartile range.Measures of shape include looking for clusters,gaps, and outliers.
Composite figures are composed of several geometric shapes and are three-dimensional shapes. The first composite shape is a combination of a rectangular prism and a pyramid. To find the volume of the entire shape you find the volume of each individual shape and add them together. The second figure consists of a cylinder and a hemisphere. Check out the video below for the full lesson.
