The population of the city in the year 2015 will be 51,600.
The rate of change is the speed at which variable changes over a specific period of time.
The population of the city in the year 2005 = 36,000
The population of the city in the year 2010 = 43,800
The change in population in 5 years is given by;
= Population in the year 2010 - Population in the year 2005
= 43,800 - 36,000
= 7800
The change in population in 5 years = 7800
Let us assume the number population in the year 2015 = x
Here, according to the question:
Since the change of rate is a linear growth since 2005.
The change in population every 5 years = 7800
The change in population in the next 5 years is;
Rate of change = Population in year 2015 - Population in the year 2010
7800 = x - 43,800
x = 7800 + 43800
x = 51,600
Hence, the population of the city in the year 2015 will be 51,600.

Step-by-step explanation:
Based on the right-angle triangle shown below, thesine of ∠A include the following: B.) 3/5.
In order to determine the magnitude of angle A, we would apply the basic sine trigonometric ratio because the given side lengths represent the opposite side (CB) and hypotenuse (AB) of a right-angled triangle;
sin(θ) = Opp/Hyp
Where:
Based on sine trigonometric ratio, the magnitude of angle A can be calculated as follows:
sin(θ) = Opp/Hyp
sin(A) = CB/AB
sin(A) = 3/5.
In conclusion, we can reasonably and logically deduce that thesine of angle A (m∠A) is 3/5.

Answer:
c=20
Step-by-step explanation:
84c −4 = 72c−244
subract 72x from both sides
12c-4=-244
add 4 to both sides
12c=240
divide both sides by 12
c=20
Answer:
Step-by-step explanation:
The multiplier of her original salary to her reduced salary is ...
(1 - 10%) = 0.90
The multiplier of her reduced salary after her raise is ...
(1 +30%) = 1.30
The multiplier of her raised salary from her original salary is ...
(0.90)(1.30) = 1.17 = (1 +17%)
Her salary after the 17% raise is ...
1.17·1500/mo = $1755/mo
Answer:
17 %
Step-by-step explanation:
new salary=1500(0.9)(1.3) =1755 $
increase=1755-1500=255 $
% increase=(255/1500)×100=17
