Bearings can be given from any direction, not just due north. for bearings, like azimuths, clockwise angles are
represented by positive degrees and counterclockwise angles are represented by negative degrees. a ship is
traveling 30° east of north at 18 kn, then turns 20°, maintaining its speed.
a. draw a picture representing the situation.
b. find vectors v and w representing the first and second bearing.
c. find the sum of v and w. what does v + w represent?
d. if the ship travels for one hour along each bearing, then how far north of its starting position has it traveled?
how far east has it traveled?

Plot the intercepts to graph the equation

What function has a range {yly< 5}? question on picture above^

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?
