Answers

Answer:

(13/2)^27

Step-by-step explanation:

First note that ( )^0 = 1, so we need not bother with the last term.

Next, note that

 (2/13)^(-6) divided by (2/13)^3 is (2/13)^(-9).

Finally, we must cube this last result.  We get:  (2/13)^(-9*3) = (2/13^(-27)

or

(13/2)^27

Note:  we're "evaluating" an algebraic expression here, not "solving it," since there is no equation here.

Written as a simplified polynomial in standard form, what is the result when
(3x – 2)2 is subtracted from 9?

Answers

Answer:

-9x^2 + 12x + 5

Step-by-step explanation:

I'm assuming you meant (3x – 2)^2.  The " ^ " indicates exponentiation and is required.  We then have:

9 - (3x – 2)^2, which, when expanded, is

9 - (9x^2 -12x + 4), or:

-9x^2 + 12x + 5

Answers

Answer:

3.27

Step-by-step explanation:

Let us assume that the values are the side of a right triangle where;

Hypotenuse = 6 (longest)

Angle of elevation = 33 degrees

Required

x = opposite side

Using the trig identity

Sin theta = opp/hyp

Sin 33 = x/6

x = 6sin33

x = 6(0.5446)

x = 3.27

Hence the value of x is 3.27

Note that the values of the sides are assumed.

Select one

None of the above

Answers

Answer:

both (x - 5) and (x - 3) are factors of x^2  - 2x + 15

Step-by-step explanation:

Please write this all on one line:  x^2  - 2x + 15.

Recognize that 3*5 = 15.  Possible factors of x^2  - 2x + 15 are thus (x - 5) and (x + 3).  Multiplying these together results in x^2  - 2x + 15, so we have verified that both (x - 5) and (x - 3) are factors of x^2  - 2x + 15.

Given:

f(x) = x² - 2x + 15

Solution:

This function f(x) will have the negative "discriminant" in root ; thus forming complex roots

So this function has no rational roots

∴ None of the above is the right answer .
