What is the domain of 4x equals 13-4y?
Since your expression is a linear equation your domain would be all real numbers. This means all of the units on the x-axis.
How do you find the y-coordinate vertex of a parabola?
Once you calculate the X coordinate using the axis of symmetry (X=-b/2a), you plug that value in for all of the X's in the equation of the parabola. You then solve the equation for the value of Y.
Why is a degree one polynomial equation ax plus by plus c equals 0 called a linear equation?
Select any set of values for x. For each one calculate the value of y for which the equation is true. If you plot these points on the x-y plane, they will all lie on a straight line. [The word "linear" refers to line.]
How can you use a balance scale and a metric ruler to find the density of a rectangular solid?
Measure the solid to determine its length, width, and height. Multiply all three to get its volume. Weigh the solid to determine its weight. Divide weight by volume to get density. Convert as needed to the appropriate units.
How do we find all real numbers in a equation?
You solve the equation.
How do i calculate the length of the sides of a rectangle if i know the acerage?
Use the formula Area = length x width or length = area/ width All units need to be the same in an equation like this
What is the density of a board whose dimensions Cm by10.6 cm by 199 cm and whose Masses 28.6 kg?
If it's a rectangular block, you need three numbers for the dimensions, not two. In any case, to get the density, just calculate the volume, then divide the mass by the volume. That will give you the density. If you first convert all units of length to decimeters (1 dm = 10 cm), you'll get the volume in liters, and the density in kilogram/liter. You might also convert all units to meters; in that case, the volume will be in cubic meters, and the density in kilograms/cubic meters. In the latter case, the numbers will be a thousand times larger, because of the units used.
What the formula for caculating density?
First of all please spell 'calculating' correctly; NOT caculating. The equation for calculating density is ;_ Density = mass / volume This can be reduced to '- d = m/v We can insert the units of density , in metric d = m(kg) / v( cm^3) or in Imperial d = m(lb (pounds)) / v (cu.ins(cubic inches)).
If all the terms in an equation have same units then is it necessary that they have same dimensions?
if they have same units they must have same dimensions . but thy can have different units even if they have same dimensions i hope it helps :
When dose density ocur in liquids?
Density is always present in liquids (and in all matter), you can calculate it by dividing the liquid's mass by it's volume.
What is the equasion for mass and density and volume?
A list for all the possible ways to solve for mass density and volume would take a one thousand page textbook to complete, but if you are talking about all of them in the same equation it is mass=density*volume
Density of soybean oil at 31 degree Celsius?
you all need to learn SI units! what a shame!
How do you calculate Vacancy Rate?
Monthly Vacancy Allowance: (# of units vacant/total # of units) x time vacant x total month's rent roll for all units
Why are units of measurements converted?
Some units of measure are easier to calculate with than others. For example, all metric units can be easily multiplied or divided by units of ten to reach another unit of measurement.
How do you calculate grams per squre meter if density and thickness of film known to us?
D=m/v where D is the Density m is the mass and v is the volume You have to make sure all you units match up. You may have to do some conversions. Density is usually in g/cm^3. cm^3 can easily be converted to m^2. 1cm=.01m The thickness is the volume.
How much weight 10 mm steel bar in 1 square foot?
Convert all the measurements to compatible units, for example, decimeters. Calculate the volume. Look up the density of steel, then use the formula: mass = density x volume If you converted to SI units, that will give you the mass (not the weight) in kilograms. To actually convert to weight, multiply by 9.8 (assuming normal Earth gravity); this will give you the weight in newton.
Is density a new unit?
'Density' is not a unit at all. Density is how tightly atoms in an object are packed together. Therefore, density isn't a new unit, or a unit at all for that matter. The SI units of density are kg m-3. It common use the cgs unit g cm-3 is much more prevalent.
