what new realization do you have about finding the nth term of the arithmetic sequence and finding the arithmetic means how would you use this in making decision ​

Answers

Step-by-step explanation:

Arithmetic Sequnce in our daily life

The knowledge of calculating the nth term of a sequence can be very helpful. Calculating loans, discounts, salary, savings are some of the use of arithmetic method. If I save P5 per day for 5 years, I can simply use arithmetic sequence to find how much I saved from day 1 to last. Salary increase can also be solved using arithmetic sequence. Below is an example.

Sample real life problem:

1. I earn P300 on the first day. After each succeeding day, I earn P2 more than the previous day. How much should I be able to earn after 30 days?

In this situation, I would use the arithmetic sequence formula which is:

an = a1 + (n - 1)d

an is the nth term

a1 is the first term

n is the term position

d is the common difference

Lets subsitute:

an = P300 + (30 - 1)P2

an = P358

I should earn P348 at the end of 30 days

Write the slope-intercept equation of the line passing through (3.4, 17.8) and (5.7, 64.7). Round the final slope and y-intercept to the nearest tenth in your answer. Show clear work.

Answer:​

Answers

Answer:

y = 20.39x - 51.526

Step-by-step explanation:

y2 - y1 / x2 - x1

64.7 - 17.8 / 5.7 - 3.4

46.9/2.3

= 20.39

y = 20.39x + b

17.8 = 20.39(3.4) + b

17.8 = 69.326 + b

-51.526 = b

Which equation is the inverse of 2(x - 2)2 = 8(7 + y)?
O -2(x - 2)2 = -8(7 + y)
O yx2-
o yo hx²-x-6
y=-2+ 28+4x
O y=2+28+4x

Answers

Answer:

-2(x-2)2=-8(7+y)

Step-by-step explanation:

Inverse means just -

Lets solve afterwards

[tex]\\ \sf\longmapsto -2(x-2)2=-8(7+y)[/tex]

[tex]\\ \sf\longmapsto (-2x+4)2=-56-y[/tex]

[tex]\\ \sf\longmapsto -4x+8=-56-y[/tex]

[tex]\\ \sf\longmapsto -4x+y=-64[/tex]

[tex]\\ \sf\longmapsto 4x-y=64[/tex]

Answer:

-2(x - 2)2 = -8(7 + y)

Step-by-step explanation:

2(x - 2)2 = 8(7 + y)

(2x - 4)2 = 56 + y

4x - 8 = 56 + y

4x - 8 - 56 = y

4x - 64 = y

If option A

-2(x - 2)2 = -8(7 + y)

(-2x + 4)2 = - 56 - y

- 4x + 8 = - 56 - y

- 4x + 8 + 56 = - y

- 4x + 64 = - y

4x - 64 = y
