During the time interval 0 population of deer in a forest, in deer per week, can be modeled by the
differentiable function E(t), where t is measured in weeks. At time
t = 7 there are 210 deer in the forest. What is the best interpretation
of the statement E'(7) = 100?

but which class are u may know that first

the answer to this is a. a^2 + b^2 = c^2

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
