  • Answer:

<em>- ( t⁶ + 9t⁵ + t³ + 4t² - 45t )</em>

  • Step-by-step explanation:

<em>Hi there !</em>

<em>(5 - t - t⁴)(9t + t²) =</em>

<em>= 45t + 5t² - 9t² - t³ - 9t⁵ - t⁶</em>

Answer:

The answer is B

Step-by-step explanation:

Definition of margin of error is simply expected error from result of a survey. Which means the actual vote results are in the range of plus or minus %3.

On this survey the result is %55 percent in favor of Taylor and the margin of error is %3. That means in the real election Taylor will get votes in between %52-%58. In other word

0.55-0.03=0.52

The sample proportion minus the margin of error is greater than 0.50, which provides evidence that more than half of all likely voters plan to vote for candidate Taylor.

Use the ratio test to show that the series is convergent.<br><br> Thank you!
igor_vitrenko [27]

Step-by-step explanation:

lim(n→∞) |aₙ₊₁ / aₙ|

lim(n→∞) | (4ⁿ⁺¹ / (n+1)!) / (4ⁿ / n!) |

lim(n→∞) | (4ⁿ⁺¹ / (n+1)!) × (n! / 4ⁿ) |

lim(n→∞) | 4 / (n+1) |

0

Since the limit is less than 1, the series converges.
