The average annual salary of the employees of a company in the year 2005 was $70,000. It increased by the same factor each year

and in 2006, the average annual salary was $82,000. 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)?

Options: 
(A) f(x) = 70(1.17)^x
(B) f(x) = 82(1.17)^x
(C) f(x) = 70(2.2)^x
(D) f(x) = 82(2.2)^x
Base is 2005 salary, 70,000.

Change is 82,000/70,000 = 1.17

Correct answer is: A) f(x) = 70(1.17)^x

We can make use of the general formula for the geometric series to generate the function representing the average annual salary.
an = a0(r)^(n-1)

Or
f(x) = a0(r)^(x - 1)

Plugging in the given values for the year 2005 and 2006 to ge the value of r.
82000 = 70000 (r)^(1-1)
r = 1.1714

Therefore, the function is:
f(x) = 70,000 (1.1714)^(x-1)

Answer: Area: D. 32\frac{6}{20}

Step-by-step explanation:

Step 1: Convert the Expressions

4\frac{3}{4}*6\frac{4}{5}

\frac{19}{4}*\frac{34}{5}

Step 2: Reduce the Numbers

\frac{19}{4}*\frac{34}{5}

\frac{19}{2}*\frac{17}{5}

Step 3: Multiply

\frac{19}{2}*\frac{17}{5}

\frac{323}{10}

Step 4: Simplify

\frac{323}{10}

32\frac{6}{20}

Marizza181 [45]

Given:

\text{ Dimension = 3}\times5

Sol:

Area of picture is:

\begin{gathered} =\text{ length}\times\text{ Width} \\  \\ =15 \end{gathered}

If the cost $10 per square inch then price of 15 square inch is:

\begin{gathered} =15\times10 \\  \\ =150 \end{gathered}

If the quadruple of dimension that mean:

\begin{gathered} \text{ l ength = 4 length} \\  \\ Width\text{ = 4 width} \end{gathered}

So area is:

\begin{gathered} A=4\text{ length}\times4\text{ Width} \\  \\ A=4(15) \\  \\ A=60 \end{gathered}

So price is:

\begin{gathered} =60\times10 \\  \\ =600 \end{gathered}

Which is the slope of the like represented by the equation 2x+3y=-12
Burka [1]

slope = - \frac{2}{3}

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange 2x + 3y = - 12 into this form

subtract 2x from both sides

3y = - 2x - 12 ( divide all terms by 3 )

y = - \frac{2}{3} x - 4 ← in slope- intercept form

with slope m = - \frac{2}{3}
