A plane is on its approach to land on the runway. The jet's height above the ground is given in feet as a function of the time in seconds. The following table tracks the plane as it lands: t (in seconds) n (in feet) 10 14000 15 3500 10 3000 115 2500 2000 20 25 1500

Calculate the slope. Use the formula m = What is the significance of the sign of the slope?

a. The plane is losing altitude.
b. The plane is gaining altitude.
c. The plane is remaining at a constant height.
d. The plane is losing altitude at a rate of 500 feet/second.

Dis the answer for this question

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
