Estimate the rate (in gal/hr) that your car uses gasoline when it is being driven on an interstate highway. Determine how long it would take to empty a 12-oz soft drink container at this flowrate.
Find the angle between the position vectors to the points (3, -4, 0) and (-2, 1, 0), and find the direction cosines of a vector perpendicular to both.
Determine a set of (non-orthogonal) base vectors a = j + k, b = i + k, and c = i + j. (a) Establish their reciprocal vectors and hence express the vectors p = 3i - 2j + k, q = i + 4j, and r = -2i + j + k in terms of the base vectors a, b, and c.
