Question 9 An isosceles triangle lays with its base at the surface of the water and its vertex pointing downwards. If the width of the base is 3 and the altitude is 3 (i.e. distance from water's surface to the vertex) , find the formula for w(y) that we would need if finding the hydrostatic force on the triangle. Assume that y=0 is at the water's surface, and that we measure distances as positive in the downwards direction. Enter only the formula for w(y), using y as the variable. Do not write "w(y)=".

Question 10
Suppose that for a dye-dilution problem, we are using Simpson's Rule to do the approximation of concentration, ??? c(t) dt , and
this works out to:

Based on the result above, which of the following are true? Select ALL that apply.
? ?t = 0.2 (i.e. the step size is 0.2)
? n = 8
? c(0)=0
? None of these
