If (y = kx^2), where (k) is a constant, and (y = 25) when (x = 5), what is the value of (k)?

Question

Accepted Answer

Step:1 ：First, substitute (x = 5) and (y = 25) into the equation (y = kx^2), we get (25 = k(5)^2).Step:2 ：Next, simplify the right hand side to get (25 = 25k).Step:3 ：Finally, solve for (k) by dividing both sides of the equation by 25, we get (k = 1).
