Question
A formula for estimating the weight of a trout (from measurements) is$$W=\frac{L G^{2}}{800}$$ where $L$ is its length and $G$ is its girth (the distance around the body of the fish at its largest point , both measured in inches. The weight of the fish $W$ is in pounds.a. What is the domain of the function $W$ ?b. Sue caught a trout and measured its length to be 20 in. and its girth to be 12 in. What is its approximate weight?
Step 1
The formula given is: \[ W = \frac{L G^{2}}{800} \] where \( L \) is the length of the trout in inches, \( G \) is the girth of the trout in inches, and \( W \) is the weight of the trout in pounds. Show more…

The weight $w(x)$ (in pounds) of an Atlantic salmon that is $x$ inches long can be estimated by the function.$$w(x)=\left\{\begin{array}{ll} 0.4 x-5 & \text { if } 19 \leq x \leq 21 \\ 0.8 x-13.4 & \text { if } 21<x \leq 32 \\ 1.5 x-35.8 & \text { if } x>32 \end{array}\right.$$ Calculate $w^{\prime}(x)$ and explain the physical meaning of this derivative.

The length of some fish are modeled by a von Bertalanffy growth function. For Pacific halibut, this function has the form $L(t)=200\left(1-0.957 e^{-0.18 t}\right)$ where $L(t)$ is the length (in centimeters) of a fish $t$ years old. [UW] a. What is the length of a newborn halibut at birth? b. Use the formula to estimate the length of a 6 -year-old halibut. c. At what age would you expect the halibut to be $120 \mathrm{~cm}$ long? d. What is the practical (physical) significance of the number 200 in the formula for $L(t) ?$
