The population of deer in a forest was measured to be 1938 in the year 2010. If the population increased by a steady 4% a year which of the following calculations would predict its population in 2013

Alex drew a circle with right triangle prq inscribed in it, as shown below: the figure shows a circle with points p, q, and r on it forming an inscribed triangle. side pq is a chord through the center and angle r is a right angle. arc qr measures 80 degrees.

Based on the diagram, match the trigonometric ratios with the corresponding ratios of the sides of the triangle. tiles : cosb sinb tanb sincposs matches: c/b b/a b/c c/a

Bring the fraction a/a-4 to a denominator of 16-a^2
