<u><em>x=5/8 is the correct answer.</em></u><em> </em>First you had to simplify from both sides of equation, and it gave us,
. Then you add 1/4 from both sides of equation, and it gave us,
. And it gave us the answer is<u><em> </em></u><u><em>x=5/8 is the final answer. </em></u>Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
Answer:
![508.9\ in^{3}](https://tex.z-dn.net/?f=508.9%5C%20in%5E%7B3%7D)
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
![V=\pi r^{2}h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7Dh)
In this problem we have
![r=18/2=9\ in](https://tex.z-dn.net/?f=r%3D18%2F2%3D9%5C%20in)
![h=2\ in](https://tex.z-dn.net/?f=h%3D2%5C%20in)
substitutes
![V=\pi (9^{2})(2)=162\pi\ in^{3}](https://tex.z-dn.net/?f=V%3D%5Cpi%20%289%5E%7B2%7D%29%282%29%3D162%5Cpi%5C%20in%5E%7B3%7D)
Assume ![\pi =3.1416](https://tex.z-dn.net/?f=%5Cpi%20%3D3.1416)
![V=162\pi\ in^{3}=162(3.1416)=508.9\ in^{3}](https://tex.z-dn.net/?f=V%3D162%5Cpi%5C%20in%5E%7B3%7D%3D162%283.1416%29%3D508.9%5C%20in%5E%7B3%7D)
Hello:
6x²+1 = x²+4
5x² = 3
x² = 3/5
the system has two solutions ( X² =b ..b> 0 has two solutions : ± <span>√b)
</span>x = √(3/5) or x = - √(3/5)
if : x = √(3/5) y = √(3/5) ² +4 =3/5 +4 =23/4
if : x = - √(3/5) y =(- √(3/5)) ² +4 =3/5+4 =23/4
<span>The graphs of the equations intersect each other at two places (points) :
A(</span>√(3/5) , 23/4) and B (-√(3/5) , 23/4)
