4ft (w) x 3 ft(d) box concrete culverts (n=0.013, entrance has 90-degree and 15-degree wingwall flares) carry 150 cfs along a 31-m length of pipe constructed at 1.0 % slope. the tailwater depth is 2 ft.

(a) what is the headwater depth?
(b) are the culverts flowing under inlet or outlet control conditions?

Total marketing effort is a term used to describe the critical decision factors that affect demand: price, advertising, distribution, and product quality. define the variable x to represent total marketing effort. a typical model that is used to predict demand as a function of total marketing effort is based on the power function: d = axb suppose that a is a positive number. different model forms result from varying the constant b. sketch the graphs of this model for b = 0, b = 1, 0< b< 1, b< 0, and b> 1. (we encourage you to use excel to do this.) what does each model tell you about the relationship between demand and marketing effort? what assumptions are implied? are they reasonable? how would you go about selecting the appropriate model?
