Answer:
the original population of the city is 7,505,833
Step-by-step explanation:
Given;
new of the population of the city, Y = 9,007,000
the percentage increase of the city, = 20% = 0.2
Let the original population of the city = X
New population, Y = X + 0.2X
Y = X(1 + 0.2)
Y = X(1.2)
Y = 1.2X
X = Y/1.2
X = (9,007,000) / 1.2
X = 7,505,833
Therefore the original population of the city is 7,505,833

Done below!
Step-by-step explanation:
(x - root)
(x - 2)(x - (-1))(x - (-5)) = (x - 2)(x + 1)(x + 5)

we know that
The graph of g(x) is a translation of the function f(x)
so

the vertex of f(x) is the point 
the vertex of g(x) is located
units above and
units to the right of the vertex of f(x)
The rule of the translation is

<u>Find the vertex of the function g(x)</u>

the vertex of g(x) is the point 
the equation of the function g(x) in the vertex form is equal to

where
(h,k) is the vertex
substitute the value of the vertex in the equation

<u>the answer is</u>

Step-by-step explanation:
present temprature outside=10 degree
temp drops every hour= 5 dgree
let number of hours=h
10 9 8 7 6 5 4 3 2 1 0 hours
--l----l----l----l-----l----l-----l-----l-----l----l----l----l----l-----------
-40-35 -30 -25 -20-15 -10 -5 0 5 10 degrees
it will take 10 hours
for the temperature below -40 degree
h=10
