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 ![y=ab^{x}](https://tex.z-dn.net/?f=y%3Dab%5E%7Bx%7D)
Putting the value of x in the above formula from 1st coordinate,
![8.938=ab^{0}](https://tex.z-dn.net/?f=8.938%3Dab%5E%7B0%7D)
As
= 1
this gives a= 8.938
Now using the 2nd coordinate
![10.480=ab^{3}](https://tex.z-dn.net/?f=10.480%3Dab%5E%7B3%7D)
putting the value of a in it we have
![10.480=8.938b^{3}](https://tex.z-dn.net/?f=10.480%3D8.938b%5E%7B3%7D)
taking cube roots on both sides we get
b= 1.05448
Now putting the values of a and b in the exponential formula-
![y=8.938(1.05448)^{x}](https://tex.z-dn.net/?f=y%3D8.938%281.05448%29%5E%7Bx%7D)
In the year 2028, x=28
so,
![y=8.938(1.05448)^{28}](https://tex.z-dn.net/?f=y%3D8.938%281.05448%29%5E%7B28%7D)
y= 39.474
Hence oil consumption per day in 2028 will be 39.474 million barrels.
Answer:
For 5/11 shade in the third bubble (0.45 repeating)
Since 19 is a prime number it is not divisible by 2. So its only divisible numbers are 1 and 19 itself. So 19 multiplied by 1 equals 1
Across smallest side- smallest angle.
across largest side- largest angle
largest side is AC, so largest angle is B
smallest side is AB, so smallest angle is C
angles from smallest to largest : C, A, B
- 7 1/5 < - 2.3 < 0 < π < 23/7 is ascending order of these numbers.
What do descending order and ascending order mean?
- Climbing down the stairs of numbers starting with their highest value is another way to think of descending.
- The slide is descended while moving down it.
- Ascending order, in which the numbers are organized from lower value to higher value, is the reverse of falling order.
The values are 0 , -2.3 , π , 23/7 , -71/5
first simplify all the values 0 , - 2.3 , 3.14 , 3.28 , -7.2
now arrange all value in Ascending order
- 7.2 < -2.3 < 0 < 3.14 < 3.28
- 7 1/5 < - 2.3 < 0 < π < 23/7
