Find an equation for the nth term of the arithmetic sequence.
babymother [125]

Answer:

The common difference would be calculated as:

(a21-a19)/2

(-164--(-58 ))/2 (Replacing the values )

(-164 +58)/2 (Changing signs)

(-106)/2(Subtracting)

-53

Then we are going to replace the common difference(d) in the sequence formal with the 21st term . It is done for finding the first term of the sequence.

a21=a0+d*(n-1)

-164=a0+-53*(21-1) (Replacing the values)

-164=a1-53(20) (Subtracting)

-164=a1-1060 (Multiplying )

-164+1060=a1 (Adding 1060 on both sides of the equation)

896=a1

The answer would be : an= 896-53*(n-1), which is the option B.

If if the branding division were to experience the same percentage increase from year 2 to year 3 as they did from year 1 to yea
Sedaia [141]
Since the basis is from year 1 to year 2, calculate first for the difference of their percentages. That would be:

Difference = year 2 - year 1
Difference = 2.32% - 1.1% = 1.22%

We apply this same value of percentage increase from year 2 to year. Thus, the percentage for year 3 is:

% Year 3 = % Year 2 + percentage increase
% Year 3 = 2.32% + 1.22%
% Year 3 = 3.54%

aliina [53]
We are given with the rectangle shaped deck which has  a width of 29 feet and a perimeter of 134 feet. the perimeter of a rectangle is equal to twice the sum of length and width. hence the equation goes : 

134 ≤ 2* (29 + L)
67 <span>≤ 29 + L 
38 </span><span>≤ L 

length should be greater or less than 38 feet</span>
