Simple questions points!!! :)<br><br> Will also give you brainliest <br><br> Answer questions 3-6
olasank [31]

Answer:

3. aₙ = -9n +7

4. d = -2.4

5. a₆ = 45

6. aₙ = 133 + 4n

Step-by-step explanation:

Question 3.

a₁ = -2; aₙ = aₙ₋₁ - 9

The explicit rule for an arithmetic sequence is

        aₙ = a₁ + d(n -1 )

         d = aₙ - aₙ₋₁

        aₙ = aₙ₋₁ - 9     Subtract aₙ₋₁ from each side

aₙ - aₙ₋₁ = -9

         d = -9

For this sequence,  

aₙ = -2 – 9(n - 1)     Remove parentheses

aₙ = -2 - 9n + 9      Combine like terms

aₙ = -9n + 7

===============

Question 4

d = aₙ - aₙ₋₁

a₂ - a₁ = 6.2 – 8.6 = -2.4

a₃ - a₂ = 3.8 – 6.2 = -2.4, etc.

The common difference is

d = -2.4

===============

Question 5

aₙ = 8n – 3     Substitute the value of n

a₆ = 8×6 – 3

a₆ = 48 - 3

a₆ = 45

============

Question 6

a₁ = 137; d = 4

aₙ = a₁ + d(n -1 )

aₙ = 137 + 4(n -1 )

aₙ = 137 + 4n -4

aₙ = 133 + 4n

What 3 numbers would you use to compare 35,712
77julia77 [94]

Answer:

35,694

35,981

35,102

Step-by-step explanation:

If you're using the hundreds place for comparison, it means the digits in higher places are the same, and that digits in the hundreds place are different.

This will be true for any 5-digit number of the form ...

 (3)(5)(not 7)(something)(something).

The numbers might have digits to the right of the decimal point, but those are irrelevant, as are the digits in the 10s and 1s places.

A pair of shoes were originally priced at $125. They are now being sold with a 20% discount. What is it's new price?
lapo4ka [179]

Answer:

100

Step-by-step explanation:

Forumla is

Original price X rate of discount = discount

The original price is $125, the rate of discount is 20%

So in math form, this is 125 x .20

which equals 25.

Lastly, just subtract that from the original price. 125 - 25 = 100.
