Answer:
(-1,0) (0,4) (1,0)
Step-by-step explanation:
The turning points are also called the critical points. It is where the graph changes direction.
They occur at (-1,0) (0,4) (1,0)
The horizontal distance to the control tower is approximately 18506.83m
Data;
- distance from the ground = 3900m
- angle of elevation = 11.4 degrees
- horizontal distance = ?
To solve this problem, we need to use trigonometric ratio SOHCAHTOA.
In this case, we have the value of opposite and angle and we need to find the adjacent to the angle. The tangent of the angle would be perfect for this.
The horizontal distance to the control tower is approximately 18506.83m
