The simplified form of the expression [tex]x^2 - 9 / x^2 - 3x[/tex] is:

[tex](x - 3)(x + 3) / x^2 - 3x[/tex]

To simplify the expression [tex]x^2 - 9 / x^2 - 3x[/tex], we can factor the numerator and denominator if possible and cancel out any common factors.

First, let's factor the numerator and denominator:

[tex]x^2 - 9[/tex] can be factored as (x - 3)(x + 3).

[tex]x^2 - 3x[/tex] cannot be factored further.

Now, we can rewrite the expression with the factored form:

[tex](x - 3)(x + 3) / x^2 - 3x[/tex]

Next, we can look for any common factors between the numerator and denominator that can be canceled out. In this case, there are no common factors that can be canceled out.

Therefore, the simplified form of the expression  [tex]x^2 - 9 / x^2 - 3x[/tex] is:

[tex](x - 3)(x + 3) / x^2 - 3x[/tex]

Option B is correct one

B. 25 square centimeters

If you are helped with my answer pls tag me brianliest I really want it... Plzz

THANK you...

The area of the rectangle to the nearest square centimeter will be 15 square centimeters. Then the correct option is E.

Let W be the rectangle's width and L its length.

The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be

Area of the rectangle = L × W square units

A golden rectangle has a length of 5 cm. Then the width of the rectangle is given as,

W = 5 - 2

W = 3 cm

Then the area of the rectangle will be given as,

A = 5 x 3

A = 15 square centimeters

The area of the rectangle to the nearest square centimeter will be 15 square centimeters. Then the correct option is E.

mZT = 71º

Step-by-step explanation:

Complementary angles total 90º

(3x + 17) + 19 = 90

Subtract 19 from both sides

3x + 17 = 71

mZT = 71º

Subtract 17 from both sides

3x = 54

Divide both sides by 3

Answer:

[tex]v=<\sqrt{32}cos(319.11^{\circ}),\sqrt{32}sin(319.11^{\circ})>[/tex] or [tex]v=\sqrt{32}cos(319.11^{\circ})i+\sqrt{32}sin(319.11^{\circ})j[/tex]

Step-by-step explanation:

Find the magnitude of [tex]<2\sqrt{6},-2\sqrt{2}>[/tex]:

[tex]||v||=\sqrt{(2\sqrt{6})^2+(-2\sqrt{2})^2}[/tex]

[tex]||v||=\sqrt{24+8}[/tex]

[tex]||v||=\sqrt{32}[/tex]

Find the direction angle of [tex]<2\sqrt{6},-2\sqrt{2}>[/tex]:

[tex]\alpha=tan^{-1}|\frac{-2\sqrt{2}}{2\sqrt{6}}|[/tex]

[tex]\alpha=tan^{-1}|-\frac{\sqrt{3}}{2}|[/tex]

[tex]\alpha=tan^{-1}(\frac{\sqrt{3}}{2})[/tex]

[tex]\alpha=40.89^{\circ}[/tex]

Since [tex]\alpha=40.89^{\circ}[/tex] is our reference angle, we determine our direction angle [tex]\theta[/tex] by verifying our angle is in Quadrant IV, which is where the vector is located. Therefore, [tex]\theta=360^{\circ}-\alpha=360^{\circ}-40.89^{\circ}=319.11^{\circ}[/tex]

To represent a vector's magnitude and direction in trigonometric form, we use the form [tex]v=<||v||cos\theta,||v||sin\theta>[/tex] or [tex]v=||v||cos\theta i+||v||sin\theta j[/tex].

In conclusion, the trigonometric form of the vector is:

[tex]v=<\sqrt{32}cos(319.11^{\circ}),\sqrt{32}sin(319.11^{\circ})>[/tex] or

[tex]v=\sqrt{32}cos(319.11^{\circ})i+\sqrt{32}sin(319.11^{\circ})j[/tex]

Answer:

Compute the cost of driving for two different job options.

Driving costs 0.50 dollars per mile. Driving occurs 250 days per year.

Job 1

Miles each way 5

What is the cost of driving?

Job 2

Miles each way 50

What is the cost of driving?

The Total cost of driving for both the job 1 and job 2 is $1250 and $1250.

$Driving costs 0.50 dollars per mile.
Driving occurs 250 days per year.50

The statistic is the study of mathematics which deal with relations between comprehensive data.

1) job 1

ways = 5 x 2 miles
Total cost of driving  = total miles x total days x driving cost per miles
 = 10 x 250 x0.50

2) job 2
total cost of driving = 2 x 50 250 x0.5

Thus, The required Total cost of both the job 1 and job 2 is $1250 and $1250

Answer:

If x= -3 then x^2 will  be positive.

Step-by-step explanation:

we can choose the option by putting x= -3 on each option to see which of them will get us positive value..

x^3 = (-3)×(-3)×(-3) = -27

x^2=  (-3)×(-3)       =  9

2x  =  2 × (-3)   = -6

1/x =  -1/3

Thus from the values above we can see that the If x= -3 then x^2 will  be positive.
