Answer:

$x = 9$

$y = 17$

Step-by-step explanation:

This is a cyclic quadralterial so opposite angles are supplementary.

The x variables add up to 180 so

$11x + 8 + 8x + 1 = 180$

$19x + 9 = 180$

$19x = 171$

$x = 9$

The y variables add up to 180.

$6y - 4 + 5y - 3 = 180$

$11y - 7 = 180$

$11y = 187$

$y = 17$

I dont know if you wanted the steps but:

x^2-4x-6=0

plug it into the equation:

$\frac{-(-4)\sqrt{(-4)^2-4(1)(-6)}}{2(1)}$

$[tex] \frac{4\sqrt{40}}{2}$ [/tex]

$\frac{4+2\sqrt{10}}{2} \frac{4-2\sqrt{10}}{2}$

$x=2+\sqrt{10}$

$x=2-\sqrt{10}$

x^2-4/3x+1/3 x=1 , x= 1/3

2x^2-3x+1=0 x=1 , x=1/2

6x^2+12x=-5

add the 5 to both sides

6x²+12x+5=0 plug the problem into the equation

x= $\frac{-12\sqrt{12^{2}-4(6)(5)}}{2(6)}$

x=[ $\frac{-12\sqrt{144-120}}{12}$

x= $\frac{-12\sqrt{24}}{12}$

x= $\frac{-12+2\sqrt{6}}{12}$ x= $\frac{-12-2\sqrt{6}}{12}$

$\frac{-6+2\sqrt{6}}{6} \frac{-6-2\sqrt{6}}{6}$

3. Use trigonometric ratios to solve for the variable. Show your work. Round lengths to the nearest tenth and angles to the near

Lynna [10]

Answer:

x = 3.4

Step-by-step explanation:

recall that for a right angle with an internal angle θ,

cos θ = adjacent length / hypotenuse

in our case,

θ = 55 deg

adjacent length = x units

hypotenuse = 6 units

substitute these into the formula above

cos θ = adjacent length / hypotenuse

cos 55 = x / 6 (multiply both sides by 6)

x = 6 cos 55 (use calculator)

x = 3.4415

x = 3.4 (rounded to nearest tenth)

What is the greatest common factor of the terms of the polynomial 12x^4 - 6x^3 + 9x^2

choli [55]

Answer:

$3x^{2}$ is the greatest common factor of the polynomial.

Step-by-step explanation:

Given:

The polynomial is $12x^{4} - 6x^{3} + 9x^{2}$

In order to determine the greatest common factor of all the terms, we find the greatest common factor of the coefficients separately and greatest common factor of the variables separately.

So, factors of 12 = 1, 2, <u>3</u>, 4, 6, 12

Factors of 6 = 1, 2, <u>3</u>, 6

Factors of 9 = 1, <u>3</u>, 9

Therefore, the greatest common factor among 12, 6, and 9 is 3.

Now, factors of $x^{4}$ = $1, x, x^{2}, x^{3}, x^{4}$

Factors of $x^{3}$ = $1, x, x^{2}, x^{3}$

Factors of $x^{2}$ = $1, x, x^{2}$

Therefore, the greatest common factor among $x^{4}, x^{3},x^{2}$ is $x^{2}$ .

Hence, the greatest common factor of all the terms of the polynomial is $3x^{2}$
