Question

Formula of direct variation ​

Answer 1

Answer:

Direct variation problems are solved using the equation y = kx. In this case, you should use c and d instead of x and y and notice how the word “square root” changes the equation. Step 2: Use the information given in the problem to find the value of k. In this case, you need to find k when c = 6 and d = 256.

Answer 2

Answer:

Direct Variation is said to be the relationship between two variables in which one is a constant multiple of the other. If b is directly proportional to a the equation is of the form b = ka (where k is a constant)
