How is the series 5+11+17…+251 represented in summation notation?

NISA [10]

Answer:

$\displaystyle \large{\sum_{n=1}^{42}(6n-1)$

Step-by-step explanation:

Given:

Series 5+11+17+...+251

To find:

Summation notation of the given series

Summation Notation:

$\displaystyle \large{\sum_{k=1}^n a_k}$

Where n is the number of terms and $\displaystyle \large{a_k}$ is general term.

First, determine what kind of series it is, there are two main series that everyone should know:

Arithmetic Series

A series that has common difference.

Geometric Series

A series that has common ratio.

If you notice and keep subtracting the next term with previous term:

11-5 = 6
17-11 = 6

Two common difference, we can in fact say that the series is arithmetic one. Since we know the type of series, we have to find the number of terms.

Now that brings us to arithmetic sequence, we know that first term is 5 and last term is 251, we’ll be finding both general term and number of term using arithmetic sequence:

<u>Arithmetic Sequence</u>

$\displaystyle \large{a_n=a_1+(n-1)d}$

Where $\displaystyle \large{a_n}$ is the nth term, $\displaystyle \large{a_1}$ is the first term and $\displaystyle \large{d}$ is the common difference:

So for our general term:

$\displaystyle \large{a_n=5+(n-1)6}\\\displaystyle \large{a_n=5+6n-6}\\\displaystyle \large{a_n=6n-1}$

And for number of terms, substitute $\displaystyle \large{a_n}$ = 251 and solve for n:

$\displaystyle \large{251=6n-1}\\\displaystyle \large{252=6n}\\\displaystyle \large{n=42}$

Now we can convert the series to summation notation as given the formula above, substitute as we get:

$\displaystyle \large{\sum_{n=1}^{42}(6n-1)$

From a point 50m from the base of the Skylon Tower in Niagara Falls, the angle of elevation to the top of

VladimirAG [237]

Answer:

The tower is about 235 m.

Step-by-step explanation:

Let x be the height of the tower

tan θ = opp / adj

tan 78 °= x / 50

x = 50 tan 78 °

x = 235

∴ The tower is about 235 m.

Hope this answer helps you :)

Determining rational and irrational numbers quick 25 pts

Arlecino [84]

11/15 + 7 ⇒ rational ⇒ the sum of two rationals is always rational

√14+13 ⇒ irrational ⇒ the sum of a rational and an irrational is always irrational

30×√6 ⇒ irrational ⇒ the product of a nonzero rational and an irrational is always irrational

11/12 × 7/15 ⇒ rational ⇒ the product of two rationals is always rational
