horsena [70]

Answer:

System utilization = 0.7 or 70%

Step-by-step explanation:

Given arrival rate of customer = 15 customer/Hour

Servie rate = $\dfrac{60}{2.8} customer/Hour$

Now, use the below formula to find the system utilization.

System utilization = $\dfrac{\text{ Arrival rate of customer }}{\text{ Servie rate}}$

System utilization = $\dfrac{15}{ \dfrac{60}{2.8}}$

System utilization = 0.7 or 70%

Select the polynomial that is a perfect square trinomial. 36x2 − 4x 16 16x2 − 8x 36 25x2 9x 4 4x2 20x 25.

Naya [18.7K]

The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.

The given polynomial is

$a) 36x^2-4x+16$

What is the form of perfect square polynomial?

$(ax+b)^2$

we solve this method by using perfect square method

add and subtract 1/9

$36x^2-4x+16+\frac{1}{9}-\frac{1}{9}$

factor 36

$\frac{143}{9}+36(x^2-\frac{x}{9}+\frac{1}{324} )$

Now complete the square

$\frac{143}{9}+36(x^2-\frac{1}{18})^2$

Therefore this is not perfect square trinomial.

Similarly for

$b) 16x^2-8x+36$

Complete square is,

$16(x-\frac{1}{4})^2+35$

This polynomial is also not perfect square trinomial.

$c) 25x^2+9x+4\\$

complete square is,

$25(x+\frac{9}{50})^2+\frac{319}{100}$

This polynomial is not perfect square trinomial.

$d)4x^2+20x+25\\$

complete square is,

$(2x+5)^2$

This polynomial is perfect square trinomial.

Therefore,

The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.

The point V(-5, 6) is rotated 180° counterclockwise around the origin. What are the coordinates of the resulting point, V′?

zubka84 [21]

Answer:

V'(5, - 6)

Step-by-step explanation:

V(-5, 6)

For a counterclockwise rotation at 180°about the origin ;

The point (a, b) becomes - - - - > (-a, - b)

Therefore,

If ; V(-5, 6) is rotated 180° counterclockwise about the origin, we have ;

V(-5, 6) - - - - > V'(5, - 6)
