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

Help me solving number 22 & 24. Thanks:)

Answer:

Question 22

x intercept is 7

y intercept is 4

The answer is C

Question 24

x intercept is -4

y intercept is 7

The answer is B

Step-by-step explanation:

x and y intercepts are the points at which the graph meets x and y axes.

x and y intercepts can be found the following way,

y intercept - substitute 0 to x

x intercept - substitute 0 to y

Question 22

7y=28-4x

Substitute x=0 to find the y intercept

7y=28-4*0

=7y=28

=y=4

Substitute y=0 to find x intercept

7*0=28-4x

=0=28-4x

=4x=28

=x=7

Therefore,

x intercept is 7

y intercept is 4

The answer is C

<u>Question 24</u>

4y=7x+28

Substitute x=0 to find the y intercept

4y=7*0+28

=4y=28

=y=7

Substitute y=0 to find x intercept

4*0=7x+28

=0=7x+28

=-7x=28

=x=-4

Therefore,

x intercept is -4

y intercept is 7

The answer is B
