Select the correct answer. A company employs 48 people in various departments. The average annual salary of each employee is $25

Anna35 [415]

Answer:

A. $1,056,000 ≤ x ≤ $1,344,000

Step-by-step explanation:

The average annual salary of each of the 48 employees is given as;

$25,000

The total salary that the company pays to its employees annually is thus;

$25,000 * 48 = $1,200,000

Now, the total annual maximum variance of the employees salaries would be;

$3,000 * 48 = $144,000

The lower limit of the total salary that the company pays to its employees annually is calculated as;

$1,200,000 - $144,000 = $1056000

The upper limit of the total salary that the company pays to its employees annually is calculated as;

$1,200,000 + $144,000 = $1344000

Therefore, the range of the total salary that the company pays to its employees annually is;

$1,056,000 ≤ x ≤ $1,344,000

These tables represent an exponential function. Find the average rate of change for the interval from x=9 to x=10

QveST [7]

<u>ANSWER</u>

B. 39,366

<u>EXPLANATION</u>

The y-values of the exponential function has the following pattern

${3}^{0} = 1$

${3}^{1} = 3$

${3}^{2} = 9$

${3}^{3} = 27$

:

:

${3}^{x} = y$

Or

$f(x) = {3}^{x}$

To find the average rate of change from x=9 to x=10, we simply find the slope of the secant line joining (9,f(9)) and (10,f(10))

This implies that,

$slope = \frac{f(10) - f(9)}{10 - 9}$

$slope = \frac{ {3}^{10} - {3}^{9} }{1}$

$slope = \frac{59049-19683}{1} = 39366$

Therefore the average rate of change from x=9 to x=10 is 39366.

The correct answer is B.
