Health.A diet must be designed to provide at least 350 units of calcium, 175 units of iron, and 225 units of Vitamin B. Each ounce of food A contains 15 units of calcium, 25 units of iron, and 20 units of vitamin B. Each ounce of food B contains 25 units of calcium, 10 units of iron, and 10 units of vitamin B. a. Find a system of inequalities to describe the different quantities of food that may be used (let x the number of ounces of food A and y the number of ounces of food B). b. Graph the system of inequalities. c. Using the graph found in part (b), nd two possible solutions (there are innitely many).

L32 - 2 Notation Integral sign Integrand Integration Limits of integration (lower and upper) dx NOTE: n ▯ (x ) −3 ex. Express lim xie i ∆x as a deﬁnite integral on n→∞ i=1 [0,4]. Theorem: If f is continuous or has a ﬁnite number of jump discontinuities on [a,b], then f is integrable on [a,b].
