A meat market combines ground beef and ground pork in a single package for meat loaf. The ground beef is 75% lean (75% beef, 25% fat) and costs the market $0.75 per pound (lb). The ground pork is 60% lean and costs the market $0.45/lb. The meat loaf must be at least 70% lean. If the market wants to use at least 50 lb of its available pork, but no more than 200 lb of its available ground beef, how much ground beef should be mixed with ground pork so that the cost is minimized?
Module 2 Section 2.1: Properties of the Trigonometric Functions Recall the six trigonometric functions; y x y sin( )= , cos ( ) , tan( )= r r x csc( )= r , sec( )= r , cot( )= x y x y If we consider the unit circle then in each of these cases, r =1. Section 5.3 in the textbook does a very thorough job covering the topics: domain/range, period, signs, fundamental identities, finding exact values with identities. So we don't think writing anything here would add anything significant to the topics. Please read pages
