How to form a differential equation for vector space |
|
Answer» The first vector SPACE you learn about is probably the "arrows" in the xy-plane that go from the origin to any point (x,y). You can add "arrows" together -- e.g. the vector to (a,b) plus the vector to (c,d) is the ARROW from the origin to (a+c,b+d). You can scale "arrows" -- e.g. if you want to scale the vector from the origin to (a,b) by the CONSTANT c, you get the vector from the origin to the point (ca,cb). These scalable, addable "arrows" satisfy all the requirements for a vector space. |

Find the greatest number of five digit exactly divisible by 9, 12, 15, 18, 24 |
|
Answer» To FIND: ⇒ The greatest number of five-digit EXACTLY divisible by 9, 12, 15, 18, 24. Solution: ⇒ LCM of 9, 12, 15, 18 and 24 by division method is 360. The largest number of five digits = 99999. ⇒ The quotient when 99999 is DIVIDED by 360 is 277 and the remainder is 279. ⇒Greatest number of five digits divisible by 9, 12, 15, 18 and 24 = 99999 - 279 =99720. ⇒ ∴ The greatest number of five-digit exactly divisible by 9, 12, 15, 18, 24 = 99720 :) |
