What is the equation "Q equals mc delta T"?

Different substances have different specific heats since they require differing amounts of energy to change temperature by 1 degree Celsius. Q represents the heat added, c is the specific heat of the substance, m is the mass of the sample, and Δt (delta t) is the change in temperature. This equation does not work if the substance changes states at that temperature because then energy is gained or lost by the change of state. An example of a state change is water going from solid to liquid form.

The parallelogram rule is used to graphically represent the addition of complex numbers, which are treated as different sides of a parallelogram. Imaginary numbers are assumed to exist not only in complex numbers, but also in real numbers, where they are graphed on the coordinate plane because their value is zero.
What are some rules about rounding decimals?

For example, the decimal 64.225 rounded to the nearest tenth is 64.2, since the .2 in the hundredths place is less than 5. The same figure rounded to the nearest hundredth would read 64.23, as the number in the thousandths place is 5.\nLikewise, rounding 108.618 to the nearest tenth would result in rounding to 108.6, as the next decimal place is 1, which is less than 5. Rounding the figure to nearest hundredth would read 108.62, as the number in the thousandths place is 8, which is greater than or equal to 5.

The ones place (1) is one step right from the decimal place. The tens place (10) is one step right from there. From then on, the numbers get larger. Next comes the hundreds (100). After this, the numbers follow this same pattern: ones, tens, then hundreds. This is why numbers are organized in sets of three. One step right from the hundreds is the thousands (1,000), followed by the ten thousands (10,000), and hundred thousands (100,000). Then comes the millions (1,000,000), ten millions (10,000,000) and hundred millions (1000,000,000).\nNumbers keep going on forever, getting larger and larger a..

Bloodstain analysts use the arcsin in the analysis of blood splatter patterns at crime scenes. After they measure the length of the blood splatter, they can use the arcsin function to help determine the location of the victim in the room and the type of weapon used. Like the sine function, arcsin does not provide distinct numbers, meaning it is inexact and provides multiple values. Trigonometry calculators typically have an arcsin button, allowing for easy calculation.

Because they are based on real-world problems, mathematical models are often referred to collectively as applied mathematics. These models generally involve geometry, trigonometry and calculus, depending on the grade level. In the real world outside of academia, computers are often used to generate models.
What is a linear extrapolation formula?

Extrapolation is used for data prediction in several different fields, provided there is sufficient historic data. Future weather patterns, sensor signals, population growth and geographical positions are all predicted using extrapolation.\nUnlike linear interpolation, which estimates values within the range of the known data points, linear extrapolation is prone to error, and it has a higher risk of producing meaningless data. Therefore, to obtain the best-possible data, it is important to determine the nature of the function. Linear extrapolation provides acceptable data if the function is l..
When should you write numbers in numeric form?

For both writing styles, spell out all numbers that begin a sentence, except for years. Dates, ages, percentages and ratios are usually written in numeric form. Writers should avoid placing two numbers next to one another to prevent a misreading. For example, "12 20-inch tires" would be better written as "twelve 20-inch tires."

A four-sided pyramid is a tangible example of a three-dimensional geometric shape. It is easy to make a model with a piece of sturdy cardboard, a pencil, ruler, scissors and some tape.Step 1: Draw the piecesUse a ruler and a pencil to draw four equivalent triangles. Draw a square with sides equal to the measure of the base of the triangles.Step 2: Cut out the piecesUse a pair of sharp scissors to cut the five pieces out of the cardboard. If the cardboard is too thick for scissors, a craft knife works well.Step 3: Tape the pieces togetherLay out the triangle pieces and tape the sides together. ..
What are greater than and less than symbols?

These symbols are used when two numbers or equations are not equal. The number or equation that is the larger of the two is placed on the open side of each symbol and the smaller of the two is placed on the closed side of the symbol. When comparing two numbers, either symbol is used. For example, when comparing five and ten, one can write 10 > 5, since ten is larger than five. One can also write 5 < 10, because five is smaller than ten.
