Answer:
Option B.
Step-by-step explanation:
It is given that △ABC is reflected to form △A'B'C' .
It is given that the vertices of triangle ABC are A(4,1), B(6,3) and C(2,4).
From the given figure it is clear that vertices of triangle A'B'C' are A'(-4,1), B'(-6,3) and C(-2,4).
The relation between preimage and image is defined by the rule
Reflection across y-axis represented by the above rule.
It means the △ABC is reflected across the y-axis to form △A'B'C' .
Therefore, the correct option is B.

Answer: The correct option is A, itis the product of the initial population and the growth factor after h hours.
Explanation:
From the given information,
Initial population = 1000
Increasing rate or growth rate = 30% every hour.
No of population increase in every hour is,
Total population after h hours is,
It is in the form of,
Where is the initial population, r is increasing rate, t is time and [tex(1+r)^t[/tex] is the growth factor after time t.
In the above equation 1000 is the initial population and is the growth factor after h hours. So the equation is product of of the initial population and the growth factor after h hours.
Therefore, the correct option is A, itis the product of the initial population and the growth factor after h hours.
