An airplane descends from an altitude of 32,000 feet above sea level to an altitude of 27,000 feet above sea level. What is the change in altitude? 59,000 feet
-5,000 feet
-59,000 feet
5,000 feet

It's change in altitude is -5000 feet, this is because the airplane went down 5000 feet so it can't be any of the positives, and -59000 just wouldn't work because you would have to be at -27000 feet below sea level for that to work

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
