Question

Recall the definition of a direct proportion. If y varies directly as x, or y is directly proportional to x, then y = kx, where k is the variation constant. The variable r is directly proportional to the square of t. Since we see the relationship 'directly proportional,' the equation of variation for this relationship will have a format similar to y = kx. First, represent 'the square of t' as an algebraic expression involving t. Next, write the equation that expresses the relationship between the variables: r is directly proportional to the square of t. (Use k for the variation constant.) r =
