Answer:
the answer is c 3^15
Step-by-step explanation:
Part a: The value of R when
is ![3.6](https://tex.z-dn.net/?f=3.6)
Part b: The value of A when
is ![2](https://tex.z-dn.net/?f=2)
Explanation:
It is given that R is inversely proportional to A.
Hence, it can be written as ![R=\frac{k}{A}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7Bk%7D%7BA%7D)
Also, it is given that
and ![A=1.5](https://tex.z-dn.net/?f=A%3D1.5)
Substituting these values in
, we have,
![12=\frac{k}{1.5}](https://tex.z-dn.net/?f=12%3D%5Cfrac%7Bk%7D%7B1.5%7D)
![18=k](https://tex.z-dn.net/?f=18%3Dk)
Thus, the value of K is ![18=k](https://tex.z-dn.net/?f=18%3Dk)
Part a: To determine the value of R when ![A=5](https://tex.z-dn.net/?f=A%3D5)
Now, substituting
and
in
, we get,
![R=\frac{18}{5}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7B18%7D%7B5%7D)
![R=3.6](https://tex.z-dn.net/?f=R%3D3.6)
Thus, the value of R is ![R=3.6](https://tex.z-dn.net/?f=R%3D3.6)
Part b: To determine the value of A when ![R=9](https://tex.z-dn.net/?f=R%3D9)
Now, substituting
and
in
, we get,
![9=\frac{18}{A}](https://tex.z-dn.net/?f=9%3D%5Cfrac%7B18%7D%7BA%7D)
![A=\frac{18}{9}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B18%7D%7B9%7D)
![A=2](https://tex.z-dn.net/?f=A%3D2)
Thus, the value of A is ![A=2](https://tex.z-dn.net/?f=A%3D2)
