Answer:

x = 12

Step-by-step explanation:

IMPORTANT: Both answers should add up to 180 if they dont you did it wrong!

(10x - 20) + (6x + 8 ) = 180 plug in 12 for both of them

(10 * 12 - 20) + 6 * 12 + 8) = 120

(120 - 20) + (72+ 8 ) = 180

(100) + (80) = 180

so x = 12

hope this helps please make brainliest

Does someone mind helping me with this problem? Thank you!

$\frac{10-(3 \cdot 2^2 - 23)}{(1 + 10^2)-2^2 \cdot 5^2} =$

$10-\left(3\cdot \:2^2-23\right) =10-\left(-11\right) =21$

$\left(1+10^2\right)-2^2\cdot \:5^2 = 101-2^2\cdot \:5^2 = 101-4\cdot \:5^2 =101-4\cdot \:25 =101-100 = 1$

$=\frac{21}{1}$

$\frac{a}{1}= a$

$=21$

I hope I helped you!

The graph of the function f(x) is shown.

Elza [17]

Answer:

x = 2

x = -1.5

Step-by-step explanation:

The graph is of function f(x) = x²

Therefore, to find where the function intersects with y = 0.5x + 3,

equal the functions and solve for x:

⇒ x² = 0.5x + 3

⇒ x² - 0.5x - 3 = 0

Multiply both sides by 2:

⇒ 2x² - x - 6 = 0

Factor:

⇒ 2x² - 4x + 3x - 6 = 0

⇒ 2x(x - 2) + 3(x - 2) = 0

⇒ (x - 2)(2x + 3) = 0

Therefore:

(x - 2) = 0 ⇒ x = 2

(2x + 3) = 0 ⇒ x = -1.5

Use De Moivre's theorem to write the complex number in trigonometric form: (cos(3pi/12) + i sin (3pi/12))^5

Jet001 [13]

$\boxed{\text{De Moivre's Theorem: } (cos\theta + isin\theta )^{n} = cosn\theta + isin(n\theta )}$

$(cos\frac{3\pi}{12} + isin\frac{3\pi}{12})^{5} = cos\frac{5 \cdot 3\pi}{12} + isin\frac{5 \cdot 3\pi}{12}$
$= cos\frac{15\pi}{12} + isin\frac{15\pi}{12} \text{ or (A)}$
