Answer:

Step-by-step explanation:
Since the country wants to reduce the emission by the percentage each year, the function will be decaying function. The formula of decaying function will look like this

Where
E(t) = the number of emission after t years
E0= the number of initial emission= 40 million tons
r=rate of growth/decay = 35%= 0.35
t= time in years
If we put the number, the equation will be:

Its rational
Square root of 1.69 is 1.3 which is rational ( 1.3 = 13/10)
Answer:
B
Step-by-step explanation:
The line is dotted, so this allows us to eliminate A and D.
In addition, the line is shaded below, so this means the graph is for a 'less than' inequality.
So, the answer is B
