37/30 as an improper fraction can be reduced to a mixed number. 37/30= 1 with a remainder of 7.
37/30= 1 7/30
However, 37 is a prime number, so 37/30 is a simplified the improper fraction can go.
37/30=37/30
Use the Law of Sines (sina/A=sinb/B=sinc/C for any triangle)
x/sin90=12/sin19
x=12/sin19
x≈36.86 to nearest hundredth
Answer:
Choice C: (x-2)^2 + (y-1)^2 = 25
Let the year represents x axis and consumption represents y axis.
Since 2010 is the initial year, x=0
and 2013 is third year , so x=3
Co-ordinates are (0,8.938)(3,10.480)
Exponential formula is 
Putting the value of x in the above formula from 1st coordinate,

As
= 1
this gives a= 8.938
Now using the 2nd coordinate

putting the value of a in it we have

taking cube roots on both sides we get
b= 1.05448
Now putting the values of a and b in the exponential formula-

In the year 2028, x=28
so,

y= 39.474
Hence oil consumption per day in 2028 will be 39.474 million barrels.
