The bird population on an island is declining at a rate of 2.2% per year. If the population was 3500 in the year 2009, which is the best prediction of the population in the year 2014

Answers

Answer 1
Answer: In the year 2009 there were 3500 birds on an island. If the bird population is declining 2.2% per year it means that in the year 2014 we will have 3500*(1-0.022^(5))=3500*0.978 x^(5)= 3131.57 birds. 
The best prediction is that in the year 2014 the bird population will be 3132.

A plane is flying due east in still air at 395 km/h. Suddenly, the plane is hit by wind blowing at 55 km/h toward the west. What is the resultant velocity of the plane?

Answers

The resultant velocity relative to the air is still 395 km/hr east.

The resultant velocity relative to the passengers is still zero.

The resultant velocity relative to the ground is (395 east) + (55 west) = 340 km/hr east.


the v towards the air is 395 kn/hr.
v towards passengers is 0.
so the v towards the ground is (395 kn/hr)east + (55km /hr)west = 340
hence solved
