<span>39 & 16.5 = -22.5
30 & 12.4 = -17.6
28 & 10.4 = -17.6
19 & 10.3 = -8.7
23 & 11.2 = -11.8
if the values are y values you will subtract them from each other to get the numerical value and because they all go from a larger number to a smaller number the rate is a negative. if they were from a smaller value to a larger value teh rates of change would be positive.

Answer:
Step-by-step explanation:
Each year, he gets a 3 percent raise. This means that his salary between consecutive years increasing by a common ratio. The formula for determining the sum of the first n terms, Sn of a geometric sequence is expressed as
Sn = (ar^n - 1)/(r - 1)
Where
n represents the number of term in the sequence.
a represents the first term in the sequence.
r represents the common ratio.
From the information given,
a = 35000
r = 1 + 3/100 = 1 + 0.03 = 1.03
Therefore, the expression that gives the total amount Alex has earned in his first n years of his career is
Sn = [35000(1.03)^n - 1]/(1.03 - 1)
Sn = [35000(1.03)^n - 1]/0.03
