The weight of a great white shark varies directly as the cube of its length. A great white shark caught off Catalina Island, California, was 15 feet long and weighed 2025 pounds. What was the weight of the 25-foot long shark in the movie Jaws?

Final answer:

The weight of a great white shark varies directly as the cube of its length. Using the given data, we can find the weight of a 25-foot long shark.

Step-by-step explanation:

We are given that the weight of a great white shark varies directly as the cube of its length. This means that the weight is proportional to the length cubed.

Let's use the formula of direct variation: y = kx^3, where y is the weight, x is the length, and k is the constant of variation.

We can use the given data to find the value of k:

2025 = k(15)^3

Now we can solve for k:

  1. 2025 = k(15)^3
  2. 2025 = 3375k
  3. k = 2025 / 3375
  4. k = 0.6

Now that we have the value of k, we can use it to find the weight of the 25-foot long shark:

Weight = 0.6(25)^3

Weight = 0.6(15625)

Weight = 9375 pounds
