Let G = { a + b 2 | a , b are rational } and H = { a 2 b b a | a , b are rational } .Show that G and H are isomorphic under addition. Prove that G andH are closed under multiplication. Does your isomorphism preservemultiplication as well as addition? ( G and H are examples of rings—a topic we will take up in Part 3.)

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.)
