<span>Let's use the quadratic formula:
2w² -</span><span><span> 20w </span>+ 50 = 0</span>
a = 2 b = -20 c = 50
x = -b +-sq root(b^2 - 4*a*c) / 2*a
x = --20 +-sq root(400 -4*2*50) / 4
x = 20 +-sq root(400 -4*2*50) / 4
x = 20 +-sq root( 0) / 4
x = 20 / 4 =5
I'd say it has one rational solution.
It does NOT have 2 solutions because the "plus / minus" section = 0.
Number of raptors in 2015: 234
% success: between 35% and 40%
Formula
% =: [number of success rescues / number of total rescues] * 100 =>
number of success rescues = % * number of total rescuess / 100
Number of success rescues:
a) 35 * 234 / 100 = 0.35 * 234 = 81.9
b) 40 * 234 / 100 = 0.40 * 234 = 93.6
Then, the number of raptor rescues that were succesfull was about 82 to 94.
Answer:
For x ≤ 2, it's a closed circle around two pointing to the left
For x < -5, it's a open circle on -5 pointing to the left.
