Write down in terms of n, an expression for the nth term
of the following sequences:
a) 12 10 8 6 4
b) 25 20 15 10 5

Write Down In Terms Of N, An Expression For The Nth Termof The Following Sequences:a) 12 10 8 6 4b) 25

Answers

Answer 1

Answer:

In bold below.

Step-by-step explanation:

a) 12 10 8 6 4

This is an arithmetic sequence with common difference -2.

nth term = a1 + (n - 1)d

= 12 + (n - 1)-2

= 12  -2n + 2

= -2n + 14.

b) 25 20 15 10 5

This is an arithmetic sequence with common difference -5.

nth term = a1 + (n - 1)d

= 25 + (n - 1)-5

= 25  - 5n + 5

= -5n + 30.

A store receives a shipment of 5,000 MP3 players. In a previous shipment of 5,000 MP3 players, 300 were defective. A store clerk generates random numbers to simulate a random sample of this shipment. The clerk lets the numbers 1 through 300 represent defective MP3 players, and the numbers 301 through 5,000 represent working MP3 players. The results are given.


948 628 87 4,987 938 468 3,589 298 2,459 2,286

Based on this sample, how many of the MP3 players might the clerk predict would be defective?

The manager would expect
defective players in the shipment.

Models are smaller than the real thing.

So if a house is 22 meters long, a model (like a Lego version) would be how long? The scale they give says 1cm (model length) = 4 meters (real length).

How many measures of 4 meters are in 22?

22/4 = 5 1/2, so the model would be 5.5 or 5 1/2 cm long.

Hope this makes sense.

Step-by-step explanation:

Divide by -9 to eliminate the -9 on -9b

(Since -9b is the same thing as -9 times b we can use the inverse of multiplication which is division to eliminate the -9 from b but we need to do it on both sides to make it balance)

Rotations, Reflections

Step-by-step explanation:

This is going to be our answer because we know that a figure has some kind of rotation.

A rotation is when a shape can be rotated in some way. A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection map every point of a figure to an image across a fixed-line.

So our answer would be Rotations, Reflections!

I have a friend Robert who is an expert at taking the difference of consecutive perfect squares. This means that if I give him a number $x$, he immediately computes $$x^2 - (x - 1)^2$$and gives me the result. I decided one day to first give Robert the number $9$, then the number $6$, and finally the number $4$. Robert gave me three numbers in return. What is the sum of these three numbers?

Answers

Answer:

35

Step-by-step explanation:

Please look at the attachment down below.

Hope this helped! :)

The  sum of three number is 35.

What is Square?

A square number is the result when a number has been multiplied by itself.

For example, 25 is a square number because it's 5 lots of 5, or 5 x 5.

Given:

if the number given is 9

9² - (9 - 1)² = 9² - 8²

                 = 81-64

                  = 17.

if the number given is 6.

6² - (6 - 1)² = 6² - 5²

                 = 36-25

                 = 11.

if the number given is 4.

4² - (4 - 1)²= 4² - 3²

                = 16-9

                = 7.

Thus, the sum of three number is

=17 + 11 + 7

= 35
