A 50-m bridge over a crevasse is supported by a parabolic arch. The function defined by f ( x ) = − 0.16 ( x − 25 ) 2 + 100 (where 0 ≤ x ≤ 50 ) approximates the height f ( x ) (in feet) of the supporting arch x meters from the end of the bridge (see figure). a .What is the location of the vertex of the arch? b .What is the maximum height of the arch (relative to the origin)?

InThe Northern Lights are bright flashes of colored light between 50 and 200 miles above Earth.
Suppose a flash occurs 150 miles above Earth. What is the measure of arc BD, the portion of Earth
from which the flash is visible? (Earth’s radius is approximately 4000 miles.)
