1) The cost for renting a car from Shady Grady Rent-a-Car is $18 per day plus 30c per mile driven. The cost of renting a similar car from EZ-Rider Rental is $20 per day plus 25€ per mile driven. Cathy needs to rent a car
for one day. Should she rent from Shady Grady or EZ
Rider?
a.) Write a cost equation for each car service. Then graph
both equations.

Line u passes through points (-52, -18) and (-29, 53). line v passes through points (90, 33) and (19, 56). are line u and line v parallel or perpendicular?

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?
