from a board 38 1/2 inches long pete cut a piece 17 5/8 inches long how long was the remaining piece
This is a question about acid rain, in Canada in particular. Acid rain is an issue in eastern Canada, but not as prevalent in western Canada, due to the fact that the east is more heavily populated and industrialized, so... If acid rain fell evenly across Canada, why would som...
after 129, add 3.. then after that, add 6.. then add 3... there's a pattern :P
Show that the equation x^3 - 15x + c = o has exactly one real root. All I know is that it has something to do with the Mean Value Theorem/Rolle's Theorem.

a = change in velocity / change in time so.. a = 8 - 32 / 4 a = -6m/s^2
A 9.0 x 10^-3 kg ball is attached to a 3.6 x 10^-2 mass (M) by string that passes through a hole in a horizontal frictionless surface. The ball travels in a circular path of radius 0.35 m. What is the speed of the ball? I know the answer is 3.7 m/s, but I'm not sure how to...

We did a lab on equilibrium and this is one of the following questions: When Ag ions are added to FeSCN ions (which are red in colour), the colour disappears, and a white precipitate of AgSCN forms. The question is.. Explain why Fe can be used as an indicator in a reaction to ...
Find (dy/dx) for the following implicitly defined function: cos(x-2y) = 3y for the answer, i got.. dy/dx = (-sin(x-2y)) / (3-2sin(x-2y)) but i'm not sure if it's right..
nevermind - i figured it out! :)
Find (dy/dx) for the following implicitly defined function: 2x = 3siny - 2y
Find the equation of the normal to the curve f(x) = 3cos(2x) at the point x = 0. In class, we learnt to find the derivate of the function, which would represent the slope. After I did that, I found the slope to be 0.. but that is not what my graphing calculator tells me.. So, ...
Using f(x) = x(4-x) write the equations of a) f(-2x) b+ -f([1/2]x)
21 - 13 is 8, and not seven. 13 + 8 = 21!
eighteen hundred = 1800 (or 18 x 100) one thousand eight hundred = 1800 also
In a complete sentence, give an example of a reaction rate that concerns many Canadians - one that involves cars, cold mornings, and cold batteries.
