What activities does Think Through Math offer?

Think Through Math provides students and educators with an interactive technology-based math program that can be used both in school and at home. The student first takes a diagnostic test to determine his math skills. The results determine the child's placement in the program and a personalized education plan that reflects his needs and classroom goals. Each plan, or pathway, aligns with state standards.\nThe Think Through Math program provides students with access to one-on-one online support from certified math teachers around the clock and throughout the year. It provides teachers with..

What are some cross product rules?

Another cross product rule or property is that a cross product is distributive. Therefore, a x (b+c) = (a x b) + (a x c). Also, the length of the cross product is equal to the area of a parallelogram, when the information supplied is from the same two vectors. A cross product is the end calculation, or vector, of two separate vectors. A cross product is perpendicular to the two vectors.

What is the difference between a plane figure and a solid figure?

The difference between plane and solid figures is in their dimensions. Where a square is a plane figure, its 3D counterpart, the cube, is a solid figure. The same comparison exists between a circle, or plane figure, and a sphere, a solid figure. Individuals create plane figures by connecting points on a grid to create 2D geometrical shapes. The same shape takes on extra dimension by adding additional points and lines to give the shape height, width and depth.

What is a number model?

A number model is an equation that incorporates addition, subtraction, multiplication and division, which are used singularly or together. In an equation, the symbols for these functions will be listed as, "+," "-," "*" and "/." As long as each part of the equation is related using some kind of sign, the equation is considered a number model.In order to be a number model, an equation must show equality. For example, the equation, "8 + 1" is not a number model because it lacks the equal sign. However, "8 + 1 = 9" is a number model.Number models can also be used to discover the perimeters and ar..

What is the derivative of secant squared?

Sec^2(x) is a composite function that can be rewritten as (sec(x))^2. The function can be decomposed into its two component functions: h(x) = (g(x))^2 and g(x) = sec(x). To find the derivative, apply the chain rule, which is d/dx(h(g(x)) = h’(g(x))g’(x).\nTake the derivative of h(x) = (g(x))^2, which is h’(x) = 2(g(x)), and substitute sec(x) for g(x) to get h’(x) = 2sec(x). Next, multiply h’(x) by the derivative of g(x) = sec(x), which is g’(x) = sec(x)tan(x). Combine the derivatives into d/dx(sec^2(x)) = 2(sec(x))sec(x)tan(x), which can be simplified into d/dx(sec^2(x)) = 2sec^2(x..

When do you use a bar graph?

Bar graphs feature rectangular bars with lengths that are directly proportional to the values they represent. A bar graph can be plotted both vertically, which is sometimes referred to as a column bar graph, or horizontally. Bar charts also resemble histograms, which can display a record of continuous data, but the main difference is the type of data that is represented in the two.

What is a residual in statistics?

Checking for residual consistency is essential in validating any regression model. This is because unpredictability and randomness are critical components of it. The validation entails examining whether or not generated random error is consistent with the residuals points. From this observation, if the residuals show that the model is systematically incorrect, then the model should be improved.

What is the inconsistent system of equations?

When solving a system of equations, the solution is either one point, no solution or infinitely many solutions. When two lines intersect, they intersect at a single point and the equations are independent. When the answer to an equation is always true, such as 3=3, the equations are dependant and a single line represents both equations on the graph. However, when solving the system gives inaccuracy or untruth, such as 0=5, the system is inconsistent and has no solution.\nBy definition, parallel lines are those that never intersect. Parallel lines have the same slope. Mathematicians use the poi..

What is the perimeter of a kite?

In a kite with a side "a" equal to 8 inches and a side "b" equal to 16 inches, the formula yields "2 times 8" plus "2 times 16." After the initial multiplication, the formula yields that the perimeter equals 16 plus 32. Thus, the perimeter of this kite is 48 inches. Alternatively, it's possible to add "a" plus "a" plus "b" plus "b," such as "8 plus 8" plus "16 plus 16."
