Answer:
The rate at which the distance from the plane to the station is increasing when it is 2 mi away from the station is 372 mi/h.
Step-by-step explanation:
Given information:
A plane flying horizontally at an altitude of "1" mi and a speed of "430" mi/h passes directly over a radar station. 


We need to find the rate at which the distance from the plane to the station is increasing when it is 2 mi away from the station. 

According to Pythagoras 


 .... (1)
               .... (1)
Put z=1 and y=2, to find the value of x.




Taking square root both sides.

Differentiate equation (1) with respect to t.

Divide both sides by 2.

Put  , y=2,
, y=2,  in the above equation.
 in the above equation.

Divide both sides by 2.



Therefore the rate at which the distance from the plane to the station is increasing when it is 2 mi away from the station is 372 mi/h.
 
        
             
        
        
        
Answer:
Your answer for F will be 13.
Step-by-step explanation:
Take 11.2 and add it to 1.8, and you will get 13 and 13 will be the variable (f). So, f (13) - 1.8 = 11.2
