Wilbur landed his plane.
2 answers:
Answer:
Step-by-step explanation:
Observe the graph provided in the exercise.
The y-axis represents the plane's elevation in meters and the x-axis represents the time in seconds.
Notice that at 0 seconds the elevation of the plane is . Based on the graph, each
the elevation of the plane decreases
The plane lands when the elevation is 0 meters and this happens when the line shown in the graph intersects the x-axis.
Therefore, the time took the plane to land is:

Answer:
vertex (5,2)
axis of symmetry: x=5
Step-by-step explanation:
vertex (h,k)
y = a(x - h)² + k
f(x)=(x-5)²+2 a = 1 h = 5 k = 2
vertex (5 , 2)
The axis of symmetry always passes through the vertex of the parabola. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
x = 5
