Area = π r²
area of the required sector = (80/360) π * 15²
≈ 157.08
The value of h is exactly the axis of symmetry. So when h changes, it completely changes the line of symmetry. This is because the vertex is (h, k) and the x value of the vertex is always equal to the line of symmetry in a quadratic.
Changing the k value does nothing to the line of symmetry. This is because it is just moving the graph up and down, which doesn't change the symmetry of a parabola.
Answer:
1.5 hours
Step-by-step explanation:
using the relationship between distance/ speed / time
distance = speed × time
speed = 
= 
= 62 mph
travelling at this rate then
time = 
= 
= 1.5 hours
