The average annual salary of the employees of a company in the year 2005 was ninety thousand dollars. It increased by the same factor each year and in 2006, the average annual salary was $91,200. Let f(x) represent the average annual salary, in thousand dollars, after x years since 2005. Which of the following best represents the relationship between x and f(x)?f(x) = 91.2(1.013)x
f(x) = 90(1.013)x
f(x) = 91.2(2.2)x
f(x) = 90(2.2)x

Answers

Answer 1
Answer: rate of growing, r = 91.2/90 = 1.013

Salary, f(x) = Initial salary * (r)^ (years from 2005)

f(x) = 90(1.013)^x.

This is the second option.

D.3.2
E.12.8

Answers

Pretty much, if its a parallelogram, and they intersect at point R, you take the length of OM (6.4) and divide it in half to get the answer D) 3.2

Answer: D. 3.2


Step-by-step explanation:

Given : In parallelogram LMNO,

LM = 4.12, MN = 4, LN = 5, and OM = 6.4.

Diagonals and intersect at point R.

We know that diagonals of a parallelogram bisect each other.

Since R is the intersection point of both diagonals.

⇒R is the mid point of OM.

Thus OR=(OM)/(2)

=(6.4)/(2)=3.2

Therefore, OR=3.2
