If y varies directly as the x^2 and y = 200 when x = 5, what is the value of y when x = -3?
gayaneshka [121]
As the variation is direct we have:
 y = kx ^ 2&#10;
 We must find the value of k.
 For this, we use the following data:
 y = 200 when x = 5
 Substituting values we have:
 200 = k5 ^ 2&#10;
 Clearing k:
 k = 200/5 ^ 2&#10;&#10;k = 200/25&#10;&#10;k = 8
 Then, the function is:
 y = 8x ^ 2&#10;
 We evaluate the function for x = -3
 y = 8 (-3) ^ 2&#10;&#10;y = 8 (9)&#10;&#10;y = 72
 Answer:
 the value of y when x = -3 is:
 c.
