Answer:
From a starting position of 13,500 feet above the ground, she is descending at 32 feet per second.
Step-by-step explanation:
The equation is in slope intercept form.
The slope (m) is -32. This can be used as a unit rate: -32 ft per second.
The y-intercept (b) is 13,500. It would make most sense if she started at 13,500 ft in height.
From a starting position of 13,500 feet above the ground, Pam is descending at 32 feet per second.
Answer:
The answer is B) From a starting position of 13,500 feet above the ground, she is descending at 32 feet per second.
Step-by-step explanation:
D does not make since because if you start at 32ft you can't fall 13,500ft. There is nowhere for you to go.
A and C don't make since because you can't fall upward.
