Step-by-step explanation:
-5>4 because it is based on formula
Answer:

Step-by-step explanation:
We can solve this system of equations by using elimination.
In this case, we can eliminate x by adding the two equations:

Then, substitute 7 for y to solve for x:

Substitute both these values into the system to check our answer:


Therefore the ordered pair is:

Step-by-step explanation:

<em>x</em> ^2 + <em>y</em> ^2 = 9 => <em>y</em> = <em>y(x)</em> = ± √(9 - <em>x</em> ^2)
Each cross section would be a square with side length equal to the vertical distance between the upper and lower semicircles defined by <em>y(x)</em>, which is
√(9 - <em>x</em> ^2) - (- √(9 - <em>x</em> ^2)) = 2 √(9 - <em>x</em> ^2)
The area of each square section is the square of this length,
(2 √(9 - <em>x</em> ^2)) = 4 (9 - <em>x</em> ^2) = 36 - 4<em>x</em> ^2
We get the whole solid for -3 ≤ <em>x</em> ≤ 3, so integrating gives a volume of
