Math 1.7

  1. Write an equation that relates the quantities.
    -W varies jointly with n and s and inversely with the cube of t. The constant of proportionality is 8.14.
    W=Image Upload 1
  2. Write a general formula to describe the variation.
    -z varise directly with the sum of squares of x and y; z=2 when x=6 and y=2
    z=Image Upload 2
  3. Write a general formula to describe the variation.
    - The square of T varies directly with the cube of a and inversely with the square of d; T=6 when a=3 and d=5
    T2=Image Upload 3
  4. Write a general formula to describe the variation.
    - y varies directly with x; y=6 when x=48
    y=Image Upload 4
  5. Decide whether the following statement is true or false.
    -If y varies directly with x, then y=Image Upload 5, where k is a constant.
    False
