Suppose the population of fish in a lake in month t is given by the equation F(t) = 800 − 500e^-0.2t

(a) Plot the equation for t in the interval [0,24].

(b) Is the function increasing, decreasing or neither? Is it concave up, down, or neither?

Solutions

Expert Solution

So , we get the required graph of given equation.

b). As we see in the graph that the given function is decreasing but it is neither concave up or cancave down.

c). when t-> infinity

f(t)->(800-500e-0.2t) and in this equation the vaule of f(t) gives more negative value because value of t and f(t) is inversely proportional that means more positive t value gives more negative f(t) value. the the whole graph forms a decreasing graph for t-> infinity.

A large population of fish live in a lake. The color of their scales is determined by two different alleles of the S gene, S1 and S2. Homozygous S1 fish have yellow scales, S2 homozygotes have blue scales, and heterozygotes are green. Scientists catch 100 fish at random and record their colors. Among those 100 fish are 30 yellow, 50 blue, and 20 green ones. After the original sample is analyzed, an asteroid landed in the lake and killed all...
