Answer:
![y=48](https://tex.z-dn.net/?f=y%3D48)
Step-by-step explanation:
Question :
Given:
varies directly with ![x](https://tex.z-dn.net/?f=x)
when ![x=2, y=16](https://tex.z-dn.net/?f=x%3D2%2C%20y%3D16)
To find value of
when ![x=6](https://tex.z-dn.net/?f=x%3D6)
Solution:
From the given data we have:
∝ ![x](https://tex.z-dn.net/?f=x)
Thus, we have:
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
where
is the constant of proportionality.
<em>We can find the value of
by plugging in the given values.</em>
when ![x=2, y=16](https://tex.z-dn.net/?f=x%3D2%2C%20y%3D16)
![16=k(2)](https://tex.z-dn.net/?f=16%3Dk%282%29)
Dividing both sides by 2.
![\frac{16}{2}=\frac{k(2)}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B2%7D%3D%5Cfrac%7Bk%282%29%7D%7B2%7D)
![8=k](https://tex.z-dn.net/?f=8%3Dk)
∴ ![k=8](https://tex.z-dn.net/?f=k%3D8)
So, the equation to find
when
will be:
![y=8\times 6=48](https://tex.z-dn.net/?f=y%3D8%5Ctimes%206%3D48)
Thus, when

Answer:
177147
Step-by-step explanation:
is the same as 3 times itself 6 times like 3x3x3x3x3x3 which is 729.
is the same as 3 times itself 5 times and you probably know what that's like but it equals 243.
No all we have to do is do a little multiplying, which would be 729 x 243 getting the answer.
177147
