What is a line graph?

To draw a line graph, a table of data is needed. There needs to be two sets of data. The first set is consistent, such as the days, months, hours or years. The second set is the measured data that is taken on the corresponding other set of data. For example, on day one, there were three correct answers on the test. The first set of numbers would be days and the second would be how many correct answers there were on the given day.

What is the difference between a rhombus and a parallelogram?

A rhombus and a parallelogram are both considered quadrilaterals. A quadrilateral is any shape with four sides. Squares and rectangles also fit this criteria. A rhombus is a square that is leaning, while a parallelogram is a rectangle that leans. Unlike squares and rectangles, neither a rhombus nor a parallelogram have angles that equal 90 degrees, which makes them easier to recognize.\nA good example of a rhombus is a diamond. The shape of a diamond has four equal sides that seem to be angled either up, down or to one side. An example of a parallelogram is a kite. The two top sides of the kit..

What is the square root of 42?

The square root of 42 is the number that can be multiplied by itself to equal 42. Most calculators have a function that calculates the square root of any positive number. One can estimate the square root of 42 by noting that 6 squared is 36 and 7 squared is 49. These results imply that the principal square root of 42 lies somewhere between 6 and 7. One can then narrow down the square root through a trial and error process.

How do you use Manual J calculations?

Manual J also takes into consideration how much heat and humidity the people living in the house add to the home's interior, as well as the home's envelope tightness, lights and its direction relative to the sun.\nThe types of Manual J load calculations include Whole House, or Block, Load Calculations and Room-by-Room Load Calculations. Whole House calculations give the loads for an entire home and are used when the existing duct system does not need modification. These calculations can assess the proper equipment size required to replace the system in an already-constructed house. R..

How do you add decimals?

For instance adding 1.345 to 2.1 is as follows:\nLine the decimals up: 1.345\n+ 2.1\nAdd (pad with) zeros: 1.345\n+ 2.100\nAdd, beginning from the right-hand column: 1.345\n+ 2.100\n= 3.445\nThere is little difference between adding decimals and whole numbers. The secret is setting up the problem in the correct way.

What are linear function word problems?

The most important step to figuring out a linear word problem is to translate the problem from words to a workable equation. This involves breaking down the problem, creating letters in place of words if necessary and arranging the problem in a way that can be figured out. For some students, this may be the most difficult part, but can be much easier if the student understands how word problems work.\n\nStudents who are having trouble figuring out how to do linear function word problems should make sure that they are familiar with word problems to ensure that they will be able to finish the pr..

What is the formula for cubic feet?

Cones and pyramids also use the same formulas for determining their volumes. For both of these shapes, v=(1/3) b*h. Calculate the area of the base of a cone as a circle with a=pi*(r^2) and the base of a pyramid using the appropriate area formula for the shape.\nUse caution when converting from cubic feet to cubic inches or cubic yards. One cubic foot equals 12 x 12 x 12 cubic inches, or 1728 cubic inches. A cubic foot is 1/27 of a cubic yard.

How do you do two-step equations with integers?

Identify the elements in a two-step equationIn a typical two-step equation, y = mx + b can be used, where y, m and b are provided and you must solve for x. An example equation that follows this pattern is 20 = 6x - 4. \nSimplify the whole numbersIsolate x by adding or subtracting the opposite of b to both sides of the equation. Using the previous example, add four to both sides of the equation, which results in 24 = 6x.Solve for xDivide both sides of the equation by m. The result is the solution to a two-step equation with integers. With the example, the resulting value is 4. Check your workPl..

What is a tangent line approximation?

For example, for the function f(x) with a point x0, tangent line approximation can be used to approximate f near x0 by a simple linear function. The tangent line approximation f(x) is approximately equal to f(x0) + f'(x0)(x - x0). The last term on the right is the equation of a straight line in x. At x = x0, the term agrees with f(x), as it takes the value f(x0) and has the same slope as the tangent to the curve at x0.

What is a nonzero digit?

Digit values are used in combinations to create representations of larger numbers. For instance, the digits 5 and 0 can represent the integers of 5 and 0 respectively, or they are capable of being combined to represent the number 50. European digits, utilized primarily in Western countries, originate from the West Arabic system. In fact, most major languages have their own digit systems, such as the formal Chinese, Assamese Bengali and Ethiopian Ge'ez systems.
