Use the given information to tfind the constant of proportionality. 14) z varies inversely as t . If t = 3, then z = 5. = ? ? k = 15. Math 1650 Homework Solutions Jason Snyder, PhD. Page 2 of 6 16) S varies jointly as p and q . If p = 4 and q = 5, then S = 180. ? = ? k = 9. 18) t is jointly proportional to x and y and inversely proportional to r . If x = 2, y = 3, and r = 12, then t = 25. ? = ? k = 50. 20) H is jointly proportional to the squares of l and w . If l = 2 and w = 1/3. then H =36. = 2 k = 81....
