T varies with the cube of w.
When w is 3, T is \(\frac{1}{9}\).
Find the value of w when T is \(\frac{1}{243}\).
Answer (2)
3...........1/9 w...........1/243
w=3* 1/243/9=
w=1/81/9=
w=1/81 * 1/9=
w=1/729
To find w when T is 243 1 , we first determine that T varies with the cube of w and calculate the constant k using the initial condition. After deriving the formula T = 243 1 w 3 , we set T to 243 1 and solve to find w = 1 .
