Answer:3 units/s
Step-by-step explanation:
Given

Point P lie on this curve so any general point on curve can be written as 
and 
Distance between Point P and (2,0)

P at x=3 P=2
rate at which distance is changing is



21 students because if 6 represents 30% u add 6 two more time which equals 18 and 90% then u add 3 more because it is half of 6. when u add 3 more u will get 21 and 100%
its the first one because for example [-12] and 4
the absolute value of -12 is 12 so its greater
Answer:
it's 5 because 20 -15 is 5
4/(6+89-34-89+190)
=4/162
=2/81
That's your answer.
