Suraj took a slice of pizza from the freezer and put it in the oven. The oven heated the pizza at a rate of 7.5^\circ7.5∘7, point, 5, degrees Celsius per minute, and it reached the desired temperature of 80^\circ80∘80, degrees Celsius after 121212 minutes.

Graph the relationship between the pizza's temperature (in degrees Celsius) and time (in minutes).

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?
