Joint variation is direct variation to more than one variable (for example, d = (r) (t)). With combined variation, we have both direct variation and indirect variation. joint variation combined variation. Sometimes there are equations or circumstances where you actually have things that vary in more than one element so example of that is in ...
Solution: First set up the equation. a varies jointly with b and c. ... Find the value of the constant, k. Given that a = 12 when b = 1 and c = 6 Rewrite the equation using the value of the constant 'k' Using the new equation, find the missing value. So, when a varies jointly with b and c and If b = 2 and c = 3, then the value of a is 12.
This can be a smart choice for couples in which one spouse has not built up a sufficient retirement reserve. A variation of the joint-life payout plan is the life annuity with period certain, under which payments continue after the annuitant’s death but at a lower dollar amount and for a limited period for the spouse or beneficiary .
Joint variation is a more complex relationship between three variables, where one variable varies directly as one variable and inversely as another. The equations expressing combined variation take the form x = ky/z.
