What is the area of a square that has a perimeter of 40metres?
Perimeter = 2 * (L + B) = 2L + 2B = 4L (all sides are equal in square)4L = 40 mSo, L = 40/4 m = 10 mArea = L2 = (10)2 = 100 m2
How many meters is 3000 mm?
The conversion factor for meters into millimeters (and vice versa) is1 Millimeter = 0.001 MeterTo make this right for 3000 meters, we simply need to multiply both sides by 3000.1x3000mm = 0.001x3000m3000mm = 3 mso its 3 meters
What is the correct method of multiplying Roman numerals by a thousand giving reasons why?
To increase a numeral by a thousandfold the Romans would have it enclosed within brackets for instance at one time the numeral for a thousand was (I) later changed to M because the Latin word for a thousand is mille hence the symbol MSo: (I) = 1,000, ((I)) = 10,000 and (((I))) = 100,000Evidence of this can be found on The Columna Rostrata, erected by the ancient Romans to commemorate their victory over the Carthaginians, in which the symbol of (((I))) is cast in stone to represent 100,000The practice of placing a bar above a numeral to signify multiplcation by a thousand was much later introduced during the Middle Ages in which other changes were made to the Roman numeral system.QED
Is a singular matrix an indempotent matrix?
A singular matrix is a matrix that is not invertible. If a matrix is not invertible, then:• The determinant of the matrix is 0.• Any matrix multiplied by that matrix doesn't give the identity matrix.There are a lot of examples in which a singular matrix is an idempotent matrix. For instance:M =[1 1][0 0]Take the product of two M's to get the same M, the given!M x M = MSo yes, SOME singular matrices are idempotent matrices! How? Let's take a 2 by 2 identity matrix for instance.I =[1 0][0 1]I x I = I obviously.Then, that nonsingular matrix is also idempotent!Hope this helps!
What is 5 million in roman numerals?
Nothing....... In Romans number the symbol is like1 -> I5 -> V10 -> X50 -> L100 -> C500 -> D1000 -> Mso u can use only these lettersso you can at the max write to 3999 ie MMMIMdrop me a mail at gaurav_herein@yahoo.com if yo need furthur clarifications.Improved answer as follows:There are several ways to express 5,000,000 in Roman numerals but the Romans themselves would have probably gone for the easiest and most effective way which would be in accordance with their general attitude to challenges and problem solving:((D)) = 500*10,000 = 5,000,000Evidence can be found today that the Romans used brackets to increase the value of their numerals. For instance on the Columna Rostrata, erected to commemorate the defeat and conquest of the Carthaginians, 100,000 is written as (((I)))and repeated 23 times to represent 2,300,000.
