2. the average monthly temperature in a coastal city in the united states is periodic and can be modeled with the
equation y = −8 cos ((x − 1) / 6)) + 17.5, where y represents the average temperature in degrees celsius and
x represents the month, with x = 1 representing january.
a. write an equation that represents x as a function of y.
b. a tourist wants to visit the city when the average temperature is closest to 25° celsius. what
recommendations would you make regarding when the tourist should travel? justify your response.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
