Question

the graph of a function passes through the point () 50, 3.6 and varies inversely as .y x find the value of when is 75. y x calculate the value of .k y x. (A)caculate the value of .k xy (B) write the equation that repersents the inverse variation function. (C) substitue the given value into the function equation and solve to determine the corresponding quantity

Answer 1

y = k/x

3.6 = k/50^2

3.6 * 50^2 = k

k = 9000
