What is the definition of "hypotenuse"?

Based on the Pythagorean Theorem, the hypotenuse can be defined as c = sqrt(a^2 + b^2), where c equals the length of the hypotenuse and a and b equal the lengths of the other two sides of a right triangle. The hypotenuse is also used in the trigonometric functions sine and cosine to find a ratio between the length of the hypotenuse and the length of one other side of the triangle. The word hypotenuse comes from a Latin term meaning "length under."

How do you describe a real life situation that could be modeled by a function?

Understand the variablesThe term "x" is simply the result of the function. "Vt" is the velocity multiplied by time, which describes the growth over a set time. Therefore, "1/2at^2" is acceleration multiplied by time, which describes the growth due to acceleration.Assign values to the variablesChoose a suitable value for both velocity and acceleration. These terms should have the same units. This is the same for the time increments as well, though the choice to use seconds over minutes is always a valid choice.Plug in the valuesPlug in all the values for the variables in the correct places. Sol..

What is the product rule?

The rule states that one obtains the derivative of a function multiplied by another function by first multiplying each individual function by the other function’s derivative. Other rules are applied as necessary, such as the power rule and the chain rule.\nThe two resulting products are then added together. Their sum is the derivative of the original two functions' product.

What is the definition of a "y-intercept?"

Finding the y-intercept of a curve requires setting x = 0 in the equation and calculating the value for y. When a line is written in the slope-intercept form y = m*x + b, b is the y-intercept. For instance, the line y + 3*x - 10 = 0 is equivalently expressed as y = -3*x + 10. The y-intercept is 10. The x-intercept is the point where a curve or a function intersects the x-axis. This is the point where y = 0.

What is the way to figure out a percentage?

When there is a question of finding a percentage, it is usually formed in the manner like the following: "If 10 out of 200 apples were spoiled, what percentage of them was bad?" Simple division helps a person find this answer.Step 1: Set up the ratio and divideUsing the example, the total number of apples is the denominator, or the number on the bottom. The number of spoiled apples is the numerator, or the number on top. The fraction looks like 10/200. Divide the denominator into the numerator. The answer will be in the form of a decimal, which is 0.05.Step 2: Multiply the answer obtained by 1..

What is the square root of 6?

If the calculation for the square root of 6 is extended indefinitely past the decimal point, the resulting decimal expansion will proceed past 1 million non-repeating digits. Therefore, the square root of 6 is considered an irrational number. The square roots of the perfect squares, such as 4, 9 and 16, are all rational numbers. There are 10 perfect squares between 1 and 100. The square roots of the remaining integers between 1 and 100 are all irrational numbers that can be expressed by nonrepeating decimals.

What is a three-dimensional rectangle called?

A cuboid in which all the edges are the same length is called a cube, which could also be described as a three-dimensional square. Calculating the volume of a cuboid is accomplished by multiplying the three edge lengths together. The surface area of a cuboid is equal to the sum of the areas of the rectangles that make up each side.

How do you make a line graph?

Creating the chart requires only a couple of steps.Get the dataThe starting point is to have two sets of data. Often this means a variable which changes in time. This should be inputted into the spreadsheet in two columns. For example, the time data in column A and the corresponding variable data in column B. The time data will be put on the X-axis of the graph, and the variable data on the Y-axis.Create a chartIn Excel, click on the Inserts tab then Charts and then click Line. This will insert the chart into the spreadsheet based on the information in the columns, including the headers.Format..

How do you calculate a discount rate?

Simply put, the discount rate is equal to the interest rate it will take to make a sum of money today equal to a value in the future, just applied in reverse. For example, if a person wants to have $100 two years from now and the current rate is 5 percent, then he should invest $90.70 today in order to reach that goal. Therefore, the discount rate of 5 percent is applied to the $100 amount in order to bring it back to the current value of $90.70. All of those calculations simply mean that $100 is worth $90.70 today.The discount rate varies depending on who is doing the calculations. Different ..
