The function F y = 149.76 10 y 5 / 2 estimates the force F (in tons) of water against the face of a dam, where y is the depth of the water (in feet). (a) Complete the table. What can you conclude from the table? (b) Use the table to approximate the depth at which the force against the dam is 1 , 000 , 000 tons. (c) Find the depth at which the force against the dam is 1 , 000 , 000 tons algebraically.

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.)
e).

Suppose you flip a fair two-sided coin four times and record the result.
a). List the sample space of this experiment. That is, list all possible outcomes that could
occur when flipping a fair two-sided coin four total times. Assume the two sides of the coin are
Heads (H) and Tails (T).
