First, simplify the denominator into 1+3i. Then multiply both the numerator and denominator by 1-3i to rationalize the denominator. Then, the numerator becomes i+3, and the denominator becomes 10. So, the first answer is correct.
Answer:
It’s not the answer but it’s a guide and something to be mindful of...
Step-by-step explanation:
You have to determine the zeros of the rational inequality by setting each factor equal to zero then solving for x. Use the zeros as critical numbers to divide the number line into distinct intervals.
Hope this helps... bless your heart.
Answer: The answer is 2x + 7.
Explanation: First, we need to add the numbers:
9x + 3 – 7x + 4
9x + 7 - 7x
And finally, we combine like terms:
9x + 7 - 7x
2x + 7
Answer:
4th degree polynomial with leading coefficient of 1.
As x goes to negative or positive infinity, y goes to positive infinity in both cases.
Step-by-step explanation:
The degree of a polynomial is the highest exponent on the variable. Here it is 4.
The leading coefficient is the coefficient on the the term with the highest degree, Here there is none so it is 1.
The end behavior is how x and y behave at negative and positive infinity. When graphed, this equation has a W shape. This means at each end y goes to positive infinity.
Answer:
565.7 cubic units
Step-by-step explanation:
Volume of cylinder=2πrh
=2x(22/7)(10)(9)
=180x(22/7)
=565.7
