Suppose c and d vary inversely, and d=2 when c=17.
a. Write an equation that models the variation.
b. Find d when c=68.
cd = k
so
2*17 = k
thus,
cd = 34
@anoymous ok so why are you here i assume you came here to look up answers
To solve this problem, we first need to understand what it means for two variables to vary inversely. When two variables vary inversely, it means that as one variable increases, the other variable decreases, and vice versa. Mathematically, this can be represented by the equation:
c * d = k
Where k is a constant that remains the same for all values of c and d.
Now let's use the given information to find the value of k. We are told that d = 2 when c = 17. Plugging these values into the equation, we have:
17 * 2 = k
34 = k
So, our equation that models the variation is:
c * d = 34
Now, to find the value of d when c = 68, we can plug this value into our equation:
68 * d = 34
To isolate the variable d, we can divide both sides of the equation by 68:
d = 34 / 68
d = 0.5
Therefore, when c = 68, d = 0.5.
why dont you at least try to answer the question- and then see if your right? not just ask . . .
i mean dont take me the wrong way- but it seems gilty 2 me...
