Answer: No answer
Step-by-step explanation:
This is not a problem :D
The quadratic model is f(x) = -5x^2 + 200.
f(x) = 50 meters
x = time in seconds
50 = -5x^2 + 200
5x^2 = 150 // Here, divide both side by 5
x^2 = 30
x =
seconds
Or approximately 5.48 seconds
1. 169, because the angles of a hexagon add up to 720. the angles given add up to 551. 720 - 551 = 169.
2. 27.225, as the formula for the area of a triangle = 1/2 x base x height
3. 95, area = b x h
4. 56.25
