It is decided that hunting will be allowed, but it is unclear how many hunting licenses should be issued. The average licensed hunter will kill 3 deer per year. (a) What is the largest number of licenses that can be issued for the deer population to survive? (b) What will happen to the deer population if this many licenses are issued? (c) Draw a bifurcation diagram for the parameter which represents the number of issued hunting licenses.arrow_forwardConsider the function below.

- Given the following line segment of length a units, draw a picture that illustrates how you a would use only a straight-edge and a compass to construct a segment of length exactly 5 units. Also, provide a written explanation of your process. You may use, without justification, the fact that if you are given a line L and a point P that is not on L, a line L' can be constructed that passes through point P and is parallel to line L. aarrow_forwardSuppose you are given only the following segment of length 1. Thoroughly describe your process for constructing a segment of length √5 using only a straight-edge and compass, and this segment of length 1.arrow_forwardConsider ∆ABC shown below. Using only a Straight edge and Compas, construct a triangle ∆A′B′C′, where A′,B′, and C′ are points in the plane distinct from A,B, and C, and such that ∆ABC is congruent to ∆A′B′C′. Please thoroughly explain your process and provide justification for how you know these triangles are congruentarrow_forward
