Can someone help please

Answer:

B is correct: (-sqrt15)/8

Step-by-step explanation:

The value of the x is 104.5° then the value of the sin 2x is -0.49. Then the correct option is B.

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

If cos(x) = -1/4 and tan(x) < 0

Then the value of the x will be

[tex]\begin{aligned} \cos x &= - \dfrac{1}{4}\\\\x &= \cos^{-1} \dfrac{-1}{4}\\\\x &= 104.5^o \end{aligned}[/tex]

Then the value of the sin 2x will be

[tex]\sin 2x = \sin 2*104.5^o\\\\\sin 2x = \sin 209^o\\\\\sin 2x = -0.4848 \approx 0.49[/tex]

Answer:

Step-by-step explanation:

1) 2^2 + 2^2 = c^2

4 + 4 = c^2

8 = c^2

c = sqrt8

2) 2^2 + 3^2 = c^2

4 + 9 = c^2

13 = c^2

c = sqrt13

3) 10^2 + 4^2 = c^2

100 + 8 = c^2

108 = c^2

c = sqrt108

4) 1^2 + 5^2 = c^2

1 + 25 = c^2

26 = c^2

c = sqrt26

5) 3^2 + 1^2 = c^2

9 + 1 = c^2

10 = c^2

c = sqrt 10

6) 9^2 + 9^2 = c^2

81 + 81 = c^2

162 = c^2

Answer:

0, π, 2π, π/6 and 5+(π/6)

Step-by-step explanation:

Rearranging, sinx (2 sinx - 1) = 0.

In [0, 2π],sin x = 0 for x = 0, π and 2π.

The other factor = 0 gives the other two solutions.

sin 5+(π/6) = sin (π−(π-6)) = sin π/6 = 1/2.

Answer:

x= -10

Step-by-step explanation:

simplify 36 - 4.5x + 36 to -4.5x + 72

simplify 102 - 7.5x - 60 to -7.5x + 42

add 7.5x to both sides

simplify -4.5x + 72 + 7.5x to 3x + 72

subtract 72 from both sides

simplify 42 - 72 to -30

divide both sides by 3

simplify 30/3 to 10

Answer: x = -10

Answer:

parallel: m= -1/5

parpendicular: m= 5

Step-by-step explanation:

parallel lines have the same slope

- 1      stays the same so      - 1  

 5                                            5

parpendicular lines have the opposite reciprocal slope

- 1      flipped is     - 5      turn the negative into a positive   5      or    5

 5                             1                                                                  1

Answer: 30

Step-by-step explanation:

24 + f = 54

f = 54 - 24

f = 30

Answer:

f=30

Step-by-step explanation:

You want to get x by itself on one side, so in order to do that, you need to subtract the 24, and if you do it one side, you need to do it to the other side.

That would give you:

24-24+f=54-24

then simplify it to be:

f=30

Answer:

121 minutes

Step-by-step explanation:

First, we divide the time by the miles

22 ÷ 2 = 11

So now that we have the unit rate, 1 mile for every 11 minutes, we can multiply 11 (the unit rate minutes) by 11 (the given miles she wants to reach)

11 x 11 = 121

So, in 121 minutes, Wendy can walk 11 miles.

(the double number line will look something like this, but going all the way until 121:11)

slope is the change in y over the change in x.

Using the first and last values:

Slope = (8 - -4)/ (2 - -2)

Slope = 12/4

Slope = 3
