Write the fifteenth term of the binomial expansion of (a^2+b)^20

3241004551 [841]

Answer:

The fifteenth term of the binomial expansion of $(a+b)^{20}$ is $38760\cdot a^{6}\cdot b^{14}$ .

Step-by-step explanation:

Let be a binomial of the form $(a+b)^{n}$ , where $a, b\in \mathbb{R}$ and $n\,\in\mathbb{N}^{+}$ . The expansion of this polynomial is defined below:

$(a+b)^{n} = \Sigma\limits_{k=0}^{n}\,\frac{n!}{k!\cdot (n-k)!}\cdot (a^{n-k}\cdot b^{k})$ (1)

Where:

$n$ - Number of terms of the expanded polynomial.

$k$ - Index associated to $k$ -th term of the expanded polynomial.

For all $n$ -th binomial, we a sum of $n+1$ terms. If the given binomial has a term of $20$ , then we have 21 terms and the fifteenth term of the polynomial corresponds to the $14$ -th term. Then, the fifteenth term of the binomial is:

$c_{14} = \frac{20!}{14!\cdot 6!}\cdot (a^{6}\cdot b^{14})$

$c_{14} = 38760\cdot a^{6}\cdot b^{14}$

The fifteenth term of the binomial expansion of $(a+b)^{20}$ is $38760\cdot a^{6}\cdot b^{14}$ .

Tyler is overdrawn at the bank by $180.His brother has $70 more than him.How much money does lyler brother have?

____ [38]

Answer: - $110

Step-by-step explanation: If Tyler is overdrawn at the bank it means that he has a negative balance. Tylers balance is -$180. If his brother has $70 more than him you need to add the two numbers together.

-$180 + $70 = -$110

Even though Tyler’s brother has more money than Tyler, his brother is still overdrawn by $110. (-$110)

Answer:

C. y=11x

Step-by-step explanation:

y = total amount of money earned

x = hours he works

y = 11x

He earns $11 per hour, so multiplying 11 by x, the number of hours, you are able to find the total amount of money he earns, y.

A model for a proposed computer chip measures 3/4 inch by 1 1/4 inches. find its area

ruslelena [56]

Here, area = l * w
l = 3/4
w = 1 1/4 = 5/4

Substitute these values in to the expression:
area = 3/4 * 5/4 = 15/16 in²

So, your final answer is 15/16 in²

Hope this helps!

A study conducted at a certain college shows that 65% of the school's graduates find a job in their chosen field within a year a

jolli1 [7]

65%= 0.65. The probability that all 11 selected graduates found a job in their chosen career would be (0.65)^11, because the probabilities are independent (one person getting a job in their field does not influence another person getting a job in their field). This comes out to 0.009 to the nearest thousandth.
