Question 200512
<font face="Garamond" size="+2">


*[tex \Large z] varies jointly as *[tex \Large x] and *[tex \Large t^2] and inversely as *[tex \Large w] means:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ z = \frac{kxt^2}{w}]


Substitute the initial values for *[tex \Large z], *[tex \Large x], *[tex \Large t], and *[tex \Large w].


Solve for *[tex \Large k]


Substitute the derived value for *[tex \Large k] into *[tex \Large z = \frac{kxt^2}{w}]


From there you can substitute any values for *[tex \Large x], *[tex \Large t], and *[tex \Large w] to determine the resulting value for *[tex \Large z].
