Answer:
- vertex: 171°
- central: 9°
- exterior: 9°
Step-by-step explanation:
The central angle is equal to the exterior angle:
360°/n = 360°/42 = 8 4/7° ≈ 9°
The vertex angle is the supplement of this:
180° -8 4/7° = 171 3/7° ≈ 171°
Answer:
D) How fast you are moving

Answer:
400 ft
Step-by-step explanation:
The building's shadow is 10 times the length of the flagpole's shadow. Since the shadow length is proportional to the object height, the building must be 10 times the height of the flagpole, so is 400 ft tall.
Answer:
domain: (-∞,∞)
Step-by-step explanation:
g of f means plug the function f(x) in to x in the function g(x)
since this is a parabola with no interval, the domain (the graph on the x-axis from left to right) is all real numbers or (-∞,∞)
