If a company has 5 employees with annual salaries of 30000 50000 30000 80000 and 70000 respectively what is the mean annual sala

Marina86 [1]

The answer is 52,000.

You have to add all of the values and divide them by the number of values. In this case you would do 30,000 + 50,000 + 30,000 + 80,000 + 70,000 which equals 260,000 then you would divide that number by 5 since there are 5 values.

Write a rational function that meets the following criteria:

Sliva [168]

You can get a vertical asymptote at x=1 using y = 1/(x-1)
You can generate a hole at x=3 by multiplying by (x - 3/(x - 3) which is undefined at x=3 but otherwise equals 1
You can move the horizontal asymptote up to y=2 by adding 2

y = (x - 3)/((x - 1)(x - 3)) + 2

Choose the expression that represents a quadratic expression. 9x − 2 5x2 9x − 1 −2x3 8x2 − 7x 1 x4 − 12x3 8x2 − 7x 1

NikAS [45]

5x² + 9x - 1 is the expression that represents a quadratic expression.

What is quadratic expression?

Quadratic expression is an expression with the variable with the highest power of 2.
The word quadratic is derived from the word quad which means square.
The expression should have the power of two and not higher or lower.

A quadratic expression is of the form

ax² + bx +c = 0 where a ≠ 0

The give options are-

9x - 2

5x² + 9x - 1

-2x³ + 8x² - 7x +1

$x^{4} - 12 x^{3} + 8x^{2} - 7x +1$

From the given options, the only expression which is quadratic is

5x² + 9x - 1

wChoose the expression that represents a quadratic expression. 9x − 2 5x2 9x − 1 −2x3 8x2 − 7x 1 x4 − 12x3 8x2 −here a =5, b=9 and c=-1

Therefore, 5x² + 9x - 1 is the expression that represents a quadratic expression.
