For number 13 x=70 and y=115 hope this helped
Answer:
4
Step-by-step explanation:
The volume of a sphere is equal to 4/3πr³.
Set up the equation;
4/3πr³=256π/3
Multiple both sides by 3/(4π):
r³=64
r=∛64=4 (ans)
Answer:
87
Step-by-step explanation:
348 divided by 4
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.
Greatest common factor can be also said by highest common factor it is the highest common factor of 2 numbers for
