For the utility function u(x, y) = x 0.5 + y 0.5 , do the following: (a) derive marshallian (uncompensated) demand functions x(px, py, i) and y(px, py, i). (hint: don’t just copy the cobb-douglas example from lecture.) (b) derive the marshallian demand curve for x(px|py, i) when py = 10 and i = 100. (c) derive equations for the engel curves of x and y when px = 5 and py = 10.

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.

Refer to interactive solution 17.45 to review a method by which this problem can be solved. the fundamental frequencies of two air columns are the same. column a is open at both ends, while column b is open at only one end. the length of column a is 0.504 m. what is the length of column b?
