The moon's distance from Earth varies in a periodic way that can be modeled by a trigonometric function.
When the moon is at its perigee (closest point to Earth), it's about 363,000 km away. When it's at its
apogee (farthest point from Earth), it's about 406,000 km away. The moon's apogees occur 27.3 days
apart. The moon will reach its apogee on January 2, 2016.
Find the formula of the trigonometric function that models the distance D between Earth and the moont
days after January 1, 2016. Define the function using radians.

What is the solution set of the quadratic inequality x^2-5< or equal to 0

Joel wants to buy a new tablet computer fram a store having a 20% off sale on all tablets. the tablet he wants has an original cost of $190. he also wants to make sure he has enough money to pay the 5% sales tax. part one joel uses the incorect expression 0.95(190)(0.8) to calculate that the tablet will cost him a total of $144.40. describe his error and write the correct expression part two how much will joel pay for the tablet show your work if you answer this question correctly you will receive a prize of 99 points good luck
