Answer:
y=40
Step-by-step explanation:
If y varies jointly as a and b
y∝ab
If y varies inversely as the square root of c
y∝![\frac{1}{\sqrt{c} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%7Bc%7D%20%7D)
Combining the two
y∝![\frac{ab}{\sqrt{c} }](https://tex.z-dn.net/?f=%5Cfrac%7Bab%7D%7B%5Csqrt%7Bc%7D%20%7D)
Introducing Variation Constant
![y=\dfrac{kab}{\sqrt{c} }](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7Bkab%7D%7B%5Csqrt%7Bc%7D%20%7D)
y=16, When a=4, b=5, c=25
![16=\dfrac{k*4*5}{\sqrt{25} }\\16=\dfrac{20k}{5}\\20k=16*5\\20k=80\\k=4](https://tex.z-dn.net/?f=16%3D%5Cdfrac%7Bk%2A4%2A5%7D%7B%5Csqrt%7B25%7D%20%7D%5C%5C16%3D%5Cdfrac%7B20k%7D%7B5%7D%5C%5C20k%3D16%2A5%5C%5C20k%3D80%5C%5Ck%3D4)
Therefore the equation connecting a. b and c is:
![y=\dfrac{4ab}{\sqrt{c} }](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B4ab%7D%7B%5Csqrt%7Bc%7D%20%7D)
We are to determine y when a=5, b=4 and c=4
![y=\dfrac{4*5*4}{\sqrt{4} }\\y=\dfrac{80}{2 }\\y=40](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B4%2A5%2A4%7D%7B%5Csqrt%7B4%7D%20%7D%5C%5Cy%3D%5Cdfrac%7B80%7D%7B2%20%7D%5C%5Cy%3D40)
The domain is the complete set of values for which x, or the independent variable, is possible for.
The range is the complete set of values for which y or the dependent variable is possible for.
Hope this helps.

the answer to the question
Answer:
x >/ 13
Step-by-step explanation:
-9+x >/ 4
add 9 to both sides. therefore:
+9-9+x >/ 4+9
0+x >/ 13
x >/ 13
