To determine the number of trout in a lake, a conservationist catches 105 trout, tags them and throws them back into the lake. Later, 39 trout are caught; 13 of them are tagged. How many trout would the conservationist expect to be in the lake?

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
