Answer:

a_n=-4n+10

Step-by-step explanation:

Let us consider the given terms one by one:

First term, a = 6

Second term, a_2=2

Difference between First and Second term = 2 - 6 = -4

Third term, a_3 = -2

Difference between Second and Third term = -2 - 2 = -4

Fourth term, a_4 = -6

Difference between Second and Third term = -6 -(-2) = -4

Therefore, the common difference is:

d = -4

Let the use the formula for n^{th} term of an arithmetic sequence:

a_n=a+(n-1)d

Putting the values of a and d:

a_n=6+(n-1)(-4)\\\Rightarrow a_n=6-4n+4\\\Rightarrow a_n=-4n+10

Therefore, the n^{th} term is:

a_n=-4n+10

A contractor bought 7.6 ft2 of sheet metal. She has used 3.5 ft2 so far and has ​$123 worth of sheet metal remaining. The equati
Sergio039 [100]

Answer:

Sheet metal remaining = 4.1x

cost per square​ foot of sheet metal = $30

Step-by-step explanation:

Total sheet metal bought = 7.6 ft2

Total sheet metal used = 3.5 ft2

Given equation:

7.6x − 3.5x = 123

Where,

x = cost per square​ foot

7.6x − 3.5x

Sheet metal remaining = 4.1x

7.6x − 3.5x = 123

4.1x = 123

x = 123 / 4.1

x = $30

Cost per square​ foot = $30

Why does the fact family for 81 and 9 have only two number sentences
qwelly [4]
Because there are only two things you can do with these two " family" members. 81 divided by 9 is 9. 9 times 9 is 81. Strictly speaking, there should be three in the family: 9,9 and 81 9 is the square root of 81. 81 is the 9 squared.
