CRITICAL THINKING The weight y (in pounds) of a rainbow trout can be modeled by y = 0.000304x3, where x is the length (in inches) of the trout. a. Write a function that relates the weight y and length x of a rainbow trout when y is measured in kilograms and x is measured in centimeters. Use the fact that 1 kilogram ≈ 2.20 pounds and 1 centimeter ≈ 0.394 inch.

Step-by-step explanation:

Given:

Where y is in pounds and x is in inches

Required

Represent y in kilogram and x in centimetre

The expression can be rewritten as

------------------------------------------------------------------------------------------------

If

Divide both by 0.394

(Approximated)

Multiply both sides by x

------------------------------------------------------------------------------------------------

If

Divide both by 2.20

(Approximated)

Multiply both sides by y

------------------------------------------------------------------------------------------------

Substitute 0.455y kg for y pound and 2.538x cm for x inch in

 Approximated

Divide both sides by 0.455

answer is 12345678900987654321234567890987654321
