A cylindrical tank holds about 615.44
djyliett [7]

Answer:

The height is 15.992 in

Step-by-step explanation:

1. The equation for a cylinder is V=\pi r^2h.  In this case, the equation looks like 615.44=\pi (3.5)^2h

2. Isolate h by dividing both sides of the equation by \pi (3.5)^2

3. This leaves us with \frac{615.44}{\pi (3.5)^2}=h

4. Solve for the left side, which leaves us with h = 15.992 (rounded to the nearest thousandth)

(20pts) Prove that the product of any two odd numbers is always odd. Make sure to explain your proof​
kozerog [31]

Answer:

See below (I hope this helps!)

Step-by-step explanation:

Because odd numbers are always 1 greater than even numbers, we can call the two odd numbers x + 1 and y + 1 where x and y are even integers. Multiplying the two gives us:

(x + 1) * (y + 1)

= x * y + x * 1 + 1 * y + 1 * 1

= xy + x + y + 1

We know that x * y will be even because x and y are also even and the sum of two even numbers will be even, and we also know that x and y are even and that 1 is odd. Since the sum of even and odd numbers is always odd, the product of any two numbers is always odd.

*NOTE: I put a limitation on x and y in my proof (the limitation was that x and y must be EVEN integers) but you don't have to do that, you could make the odd integers 2x + 1 and 2y + 1 where x and y could be any integer from the set Z like mirai123 did. I simply gave this proof because it was the first thing that came to mind. While mirai123's proof and mine are different, they are still both correct.
