Below is the solution:
Rotating around the y-axis; solve for x.
<span>y = x/3
</span><span>x = 3y
</span>
<span>Find x^2
</span><span>x^2 = 9y^2
</span>
<span>Integrating it using the limits of 0 and 3, remember to add the pi and integrate 9y^2.
</span>
The answer is <span>81pi cubic units which is A. </span>
Answer:37
Step-by-step explanation:You multiply the ones that are in the parenthes
Answer: D. Between 80 and 90 kilometers per hour
Explanation: All you have to do is multiply 1.57 x 55 (which equals 85.35). Not to be mean but all you have to do is read the answer carefully :)
The option that can be used to support the idea that the set of polynomials is closed under multiplication is; Option C: (10x^(0.5) - 8)(5x^(0.5) + 4)
<h3>What is the Closure property under multiplication?</h3>
When multiplying polynomials, the variables' exponents are added, according to the rules of exponents. It is pertinent to note that the exponents in polynomials are whole numbers. The whole numbers are closed under addition, which guarantees that the new exponents will be whole numbers. Thus, we can also say that the polynomials are closed under multiplication.
Now, looking at the options, we can say that option C is the only polynomial that is closed under multiplication because its' variables and exponents will not change;
(10x^(0.5) - 8)(5x^(0.5) + 4)
The output will retain the same thing.

Answer:
Step-by-step explanation:
- Jelly beans weight = 10 pounds
- Each bag = 2/3 pound
<u>Number of bags required:</u>
- 10 ÷ 2/3 = 10 × 3/2 = 30/2 = 15 bags
