Answer:

Seagull is 27 ft high

Step-by-step explanation:

Given in the question,

length of bridge = 54ft

angle of elevation = 30°

It is a right angle triangle question and we will use trigonometry identity to the solve the question.

sinФ = opposite / hypotenuse

sin(30) = height / 54

height = 54(sin(30)

height = 27 ft

So, seagull is 27 ft high above the ground.

For this case we have the following function:
 A (t) = A0e ^ {(kt)}

 Where,
 A0: initial population
 K: rate of change
 t: time in years
 Substituting values we have:
 A (t) = 22000 * e ^ {(- 0.021 * t)}

 For the year 2015 we have:
 A (t) = 22000 * e ^ {(- 0.021 * 5)}

A (t) = 19807
 Answer:
 
the predicted population in 2015 is:
 
19,807
