The equation that models the variation of c and d would be: c * d = k, where k is the constant of variation.
Since we know that when c = 17, d = 2, we can substitute these values into the equation to solve for k:
17 * 2 = k
34 = k
Therefore, the equation becomes: c * d = 34.
Now, to find d when c = 68:
68 * d = 34
d = 34 / 68
d = 0.5
Therefore, when c = 68, d = 0.5.
Suppose c and d vary inversely, and and d=2 when c =17.
Write an equation that models the variation.
Find d when c = 68.
