Through a series of tests on pipe flow, h, darcy derived an equation for the friction loss in pipe flow as h l = f l d v 2 2 g in which f is a dimensionless coefficient that depends on (a) the average velocity v of the pipe flow; (b) the pipe diameter d; (c) the fluid density rho; (d) the fluid viscosity μ; and (e) the average pipe wall uneveness e (length). using the buckingham π theorem, find a dimensionless function for the coefficient f.

James wants to promote his band on the internet. site a offers website hosting for $4.95 per month with a $49.95 startup fee. site b offers website hosting for $9.95 per month with no startup fee. for how many months would james need to keep the website for site a to be a better choice than site b? define a variable for the situation. write an inequality that represents the situation. solve the inequality to find out how many months he needs to keep the website for site a to be less expensive than site b. using words, describe how many months he needs to keep the website for site a to be less expensive than site b.

Compare these two waves: the blue and orange waves have the same pitch, but the blue wave is louder. the blue and orange waves have the same volume, but the blue wave has a higher pitch. the orange wave has a higher pitch, but the blue wave is louder. the blue wave has a higher pitch, but the orange wave is louder.

On a piece of paper, graph y< x+1. then determine which answer matches the graph you drew.
