Oil consumption in China grew exponentially from 8.938 million barrels per day in 2010 to 10.480 million barrels per day in 2013
Afina-wow [57]

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}

Putting the value of x in the above formula from 1st coordinate,

8.938=ab^{0}

As b^{0} = 1

this gives a= 8.938

Now using the 2nd coordinate

10.480=ab^{3}

putting the value of a in it we have

10.480=8.938b^{3}

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}

In the year 2028, x=28

so,

y=8.938(1.05448)^{28}

y= 39.474

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

Area of square= 625 m sq Perimeter =??
sveticcg [70]

Answer:

<u>100 m</u>

Step-by-step explanation:

<u>Given</u> :

  • Area of square = 625 m²

<u>#1) Finding the side length</u>

  • Area = (side length)²
  • ⇒ side length = √Area
  • ⇒ side length = √625
  • ⇒ side length = 25 m

<u>#2) Calculating perimeter</u>

  • Perimeter = Total length of the sides of the shape
  • Perimeter = 4 x side length [a square has 4 equal sides]
  • ⇒ Perimeter = 4 x 25
  • ⇒ Perimeter = <u>100 m</u>
