Awoman bails out of an airplane at an altitude of 10,000 ft, falls freely for 20 s, then opens her parachute. how long will it take her to reach the ground? assume linear air resistance pv ft/s^2, taking p =.15 without the parachute and p=1.5 with the parachute. i really mostly need to know how to set this up? what are some hints? i know terminal velocity and gravitational acceleration are involved but i don't get how to do it.

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
