A quantity y varies jointly as z and the square of x and inversely as t and the square root of w. When z = 9, x = 3, t = 9 and w = 81, then y = 1.

Step 1
We can plug these values into the equation to find the constant k: 1 = k * (9 * 3^2) / (9 * √81) 1 = k * (9 * 9) / (9 * 9) Show more…

Use the given information to find the unknown value. y varies jointly as z and the square of x and inversely as t and the square root of w. When z = 5, x = 3, t = 5, and w = 81, then y = 1. Find y when z = 3, x = 2, t = 7, and w = 36.

y varies jointly as x and the square of z and inversely as n. if y=80 when x=9, z=4, and n-18, find y when x=32, z=7, and n=35.
