Answer:

Step-by-step explanation:

The value of cos(x/2) is required.

The required value is [tex]\cos(x/2)=-\sqrt{\dfrac{5-2\sqrt{5}}{10}}[/tex]

The given value is

[tex]\tan x=\dfrac{1}{2}[/tex] where x is in quadrant III.

From trigonometric identities we have

[tex]\sec^2x=1+\tan^2x\\\Rightarrow \sec^2x=1+(\dfrac{1}{2})^2\\\Rightarrow \sec^2x=\dfrac{5}{4}\\\Rightarrow \cos^{2}x=\dfrac{4}{5}\\\Rightarrow \cos x=\dfrac{2}{\sqrt{5}}[/tex]

If x lies in quadrant III then x/2 lies in quadrant II.

Cos is negative in quadrant III so,

[tex]\cos x=-\dfrac{2}{\sqrt{5}}=-\dfrac{2\sqrt{5}}{5}[/tex]

[tex]\cos \dfrac{x}{2}=\pm \sqrt{\dfrac{1+\cos x}{2}}\\ =\pm\sqrt{\dfrac{1-\dfrac{2\sqrt{5}}{5}}{2}}\\ =\pm\sqrt{\dfrac{5-2\sqrt{5}}{10}}[/tex]

Since, x/2 lies in the second quadrant and cos (x/2) is negative.

The required value is [tex]-\sqrt{\dfrac{5-2\sqrt{5}}{10}}[/tex]

Answer:

B.) -4

Step-by-step explanation:

y=mx+b

b is equal to the y-intercept.

Answer:

-4

Step-by-step explanation:

The slope intercept form is y = mx + b.

m = slope

b = y-intercept

since b = -4, the y-intercept is -4

The measure of angle LMQ from the given figure is 97°.

In the given figure, ∠L=92°, ∠N=55°, ∠Q=85° and ∠45°.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

In ΔLMN

Using angle sum property of triangle

∠L+∠N+∠LMN=180°

⇒ 92°+55°+∠LMN=180°

⇒ 147°+∠LMN=180°

⇒ ∠LMN=180°-147°

⇒ ∠LMN=33°

In ΔMQR

Using angle sum property of triangle

∠Q+∠R+∠QMR=180°

⇒ 85°+45°+∠QMR=180°

⇒ 130°+∠QMR=180°

⇒ ∠QMR=50°

So, ∠LMN+∠LMQ+∠QMR=180° (Angles from same point on straight line)

⇒ 33°+∠LMQ+50°=180°

⇒ 83°+∠LMQ=180°

⇒ ∠LMQ=180°-83°

⇒ ∠LMQ=97°

Therefore, the measure of angle LMQ from the given figure is 97°.

Answer:

67

Explanation:

the angle labeled 10 which is =113 and the angle labeled 11 are co interior angles.

co interior angles add upto 180 therefore to get the value of the angle labeled 11 you subtract 113 from 180 which gives you 67

the angle labeled 11 which is =67 and the angle labeled 8 are alternate angles. Alternate angles are equal therefore the value of the angle labeled 8 which you've been asked to give is 67

Answer:

18

Step-by-step explanation:

So you need to do f(x) 5x^2+3x-19+3

You would simplify the equation to get to y=4x+5f(x)+2

Naturally, you would now graph the equation to a linear degree but still inducing a parabellum, y-(d-3)=0

Then solve using the square method (b/2)^2=(6)^2

Then put the 6 on both sides of the equation.

6^2+w0+8x+7t^2

Answer:

270°

Step-by-step explanation:

We know that a full circle is 360°, the shape of a clock, and that the clock is divided into 12 different sections.

Our equation would be: 360 ÷ 12 = 30

3:05 is at the 1 hand and 3:50 is at the 10 hand. Subtract 1 from 10 and you get 9.

9 · 30 = 270, so our angle is 270°

I hope this helped, please mark Brainliest, thank you!

Answer:

no because it is lower than 1 and 270 is higher

Answer:

No, because 0.000027 is a decimal. Any decimal with 0. *something* will be less than one. 27 is more than one. Thus, the statement is false.

Therefore, for this case, the correct answer is k = 7 and the way to solve it is to substitute values of x in the given functions and see the results of f (x).I attach results.

Answer:

X Intercept: (-2, 0)

Y Intercept: (0, 7)

Explanation:

Plug y = 0 into the equation and solve the resulting equation 7x = −14 for x. Plug x = 0 into the equation and solve the resulting equation −2y = −14 for y.

Answer:

(- 2, 0 ) and (0, 7 )

Step-by-step explanation:

To find the x- intercept let y = 0 in the equation and solve for x

7x - 2(0) = - 14, that is

7x = - 14 ( divide both sides by 7 )

x = - 2 ⇒ (- 2, 0 ) is the x- intercept

To find the y- intercept let x = 0 in the equation and solve for y

7(0) - 2y = - 14, that is

- 2y = - 14 ( divide both sides by - 2 )

y = 7 ⇒ (0, 7 ) is the y- intercept
