How do you calculate NGDP?
To calculate NGDP, the numbers that are needed must be entered to the equation. The proper step for the equation must be followed to calculate the NGDP.
How do you calculate efficiency and how is it expressed?
For efficiency, you have to consider the energy or work that you get out of the machine, compared to the energy or work that you put into the machine. Its what you get out, divided by what you put in. By multiplying the result by 100, you should then get the efficiency expressed as a percentage, which is the normal way of describe how efficient a machine or process is. efficiency = (Work out/Work in) x 100 Sometimes you are given the efficiency in a problem, but then have to calculate either the work out or work in, so then its just a case of rearranging the equation above.
What do you need to write in order to calculate things?
You do not need to write anything to calculate things mentally.
How do you calculate the volume of a football shaped object?
Calculus will work, if you have an equation describing the precise shape of the object. If you don't (and probably even if you do), it's far easier to actually measure it (by submerging it in water and measuring the amount of water displaced) than it is to calculate it.
How can you select data in same line?
Find (or calculate) the equation of the line. Select any value of x. Calculate the corresponding value for y using the equation. Then (x, y) is a point on the same line.
