How do you enter 'cube' into a computer?
Depends on the software. In Excel 3 cubed is entered as =3^3. The answer being 27.
How many yards of concrete do you need 80 feet by 12 inches by 18 inches?
well that is an easy one Answer in feet cubed is : X = 80 x (12/12) x (18/12) X = 80 x 1 x 1.5 X = 120 cubic Feet 1 cubic yard = 27 Cubic F so Y = 120 / 27 Y = 4.44 Now typically you would order some extra to cover for spillage
Evaluate limit x tends to 0 sinx x?
The limit as x approaches zero of sin(x) over x can be determined using the squeeze theorem.For 0 < x < pi/2, sin(x) < x < tan(x)Divide by sin(x), and you get 1 < x/sin(x) < tan(x)/sin(x)That is the same as 1 < x/sin(x) < 1/cos(x)But the limit as x approaches zero of 1/cos(x) is 1,so 1 < x/sin(x) < 1which means that the limit as x approaches zero of x over sin(x) is 1, and that also means the inverse; the limit as x approaches zero of sin(x) over x is 1.You can also solve this using deriviatives...The deriviative d/dxx is 1, at all points. The deriviative d/dxsin(x) at x=0 is also 1.This means you have the division of two functions, sin(x) and x, at a point where their slope is the same, so the limit reduces to 1 over 1, which is 1.
How many ways the word engineering can be rearranged?
the word engineering consists of eleven letters , 3 Es, 3Ns, 2Is, 2Gs and 1R. the word can be re arranged in11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2x 13 x 2 x 1 x 3 x 2 x 1 x 2 x 1 x 2 x 1= 277200 ways
