Answer:

235

Step-by-step explanation:

area of one square=

180

area of other square=

Express the terms of the following sequence by giving a recursive formula.

MAXImum [283]

The recursive formula for given sequence is: $a_n = a_{n-1}-7$

And the terms will be expressed as:

$a_1 = 11\\a_2 = a_{2-1} - 7 \\a_2= a_1 - 7\\a_2 = 11- 7\\a_2 = 4\\a_3 = a_{3-1} - 7 \\a_3= a_2 - 7\\a_3 = 4 - 7\\a_3 = -3\\a_4 = a_{4-1} - 7 \\a_4= a_3 - 7\\ a_4= -3 - 7\\a_4 = -10\\a_5 = a_{5-1} - 7 \\a_5= a_4 - 7\\a_5 = -10 - 7\\a_5 = -17\\$

Step-by-step explanation:

First of all, we have to determine if the given sequence is arithmetic sequence or geometric. For that purpose, we calculate the common difference and common ratio

Given sequence is:

11,4,-3,-10,-17...

Here

$a_1 = 11\\a_2 = 4\\a_3 = -3\\So,\\d = a_2 - a_1 = 4-11 = -7\\d = a_3-a_2 = -3-4 = -7$

As the common difference is same, given sequence is an arithmetic sequence.

A recursive formula is a formula that is used to generate the next term of the sequence using the previous term and common difference

So, the recursive formula for an arithmetic sequence is given by:

$a_n = a_{n-1} +d\\Putting\ d = -7\\a_n = a_{n-1}-7$

Hence,

The recursive formula for given sequence is: $a_n = a_{n-1}-7$

And the terms will be expressed as:

$a_1 = 11\\a_2 = a_{2-1} - 7 \\a_2= a_1 - 7\\a_2 = 11- 7\\a_2 = 4\\a_3 = a_{3-1} - 7 \\a_3= a_2 - 7\\a_3 = 4 - 7\\a_3 = -3\\a_4 = a_{4-1} - 7 \\a_4= a_3 - 7\\ a_4= -3 - 7\\a_4 = -10\\a_5 = a_{5-1} - 7 \\a_5= a_4 - 7\\a_5 = -10 - 7\\a_5 = -17\\$

What is the quotient of Negative 27. 374 divided by 7. 5 â€""3. 65 â€""0. 365 0. 365 3. 65.

Galina-37 [17]

The quotient of 27.374 divided by 7.5 is; <em><u>3.65</u></em>

We want to find the quotient of 27.374/7.5.

Now, to make this easy, let us find a way to write the decimals as whole numbers.

Thus;

27.374 = 27374 × 1/1000

Similarly, 7.5 = 75 × 1/10

Thus;

27.374/7.5 = (27374 × 1/1000)/(75 × 1/10)

>> (27374/75) × (10/1000)

>> 365 × 0.01

>> 3.65

Four students each ran 100 m in a 400-m relay race. The team’s total time was 49.44 sec. Find the average time of each runner

cupoosta [38]

To get the average time of each runner, you would divide 49.44 by 4. So you should get 12.36 for the average for each runner. Hope this helps!!
