Answer:

A: cos(-pi/3)

Step-by-step explanation:

just did the unit test review on EDGE

The trigonometric expression cos(π/12) cos(5π/12) + sin(π/12) sin(5π/12) is equivalent to cos(- π/3). Then the correct option is A.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The equivalent is the expressions that are in different forms but are equal to the same value.

The expression is given below.

⇒ cos(π/12) cos(5π/12) + sin(π/12) sin(5π/12)

We know that the formula of cosine.

cos (a - b) = cos a · cos b + sin a · sin b

Then the expression will be

⇒ cos(π/12) cos(5π/12) + sin(π/12) sin(5π/12)

⇒ cos(π/12 - 5π/12)

⇒ cos(π - 5π/12)

⇒ cos(-4π/12)

⇒ cos(- π/3)

The trigonometric expression cos(π/12) cos(5π/12) + sin(π/12) sin(5π/12) is equivalent to cos(- π/3).

Then the correct option is A.

Answer:

angle x: 50    angle 2x: 100

Step-by-step explanation:

Y = both of the blank sides because they are vertical angles

Y - (x + 100) =  180

Y - 3x = 180

Y - x = 80

2x = 100

x = 50

Step-by-step explanation:

use the distance formula to determine the distance between two points.

Options:

(12,0)     (0,12)    (3,-1)    (0,-4/3)

Answer:

(12,0) ,  (3,-1)  and (0,-4/3)

Step-by-step explanation:

Given

[tex]x - 9y = 12[/tex]

Required

Which option is true?

A coordinate point is of the form; [tex](x,y)[/tex]

So, we have to substitute the x and y values in the given equation.

A. For (12,0)

[tex]x = 12[/tex] and [tex]y = 0[/tex]

[tex]x - 9y = 12[/tex] becomes

[tex]12 - 9*0 = 12[/tex]

[tex]12 - 0 = 12[/tex]

[tex]12 = 12[/tex]

This is true

B. For (0,12)

[tex]x = 0[/tex] and [tex]y = 12[/tex]

[tex]x - 9y = 12[/tex] becomes

[tex]0 - 9*12 = 12[/tex]

[tex]- 9*12 = 12[/tex]

[tex]- 108 = 12[/tex]

This is false

C. For (3,-1)

[tex]x =3[/tex] and [tex]y = -1[/tex]

[tex]x - 9y = 12[/tex] becomes

[tex]3 - 9*-1 =12[/tex]

[tex]3 + 9 =12[/tex]

[tex]12 = 12[/tex]

This is true

D. For (0,-4/3)

[tex]x = 0[/tex] and [tex]y = -\frac{4}{3}[/tex]

[tex]x - 9y = 12[/tex] becomes

[tex]0- 9*-\frac{4}{3} = 12[/tex]

[tex]0+ 9*\frac{4}{3} = 12[/tex]

[tex]0+ 3*4 = 12[/tex]

[tex]0+12 = 12[/tex]

[tex]12 = 12[/tex]

This is true

Hence, (12,0) ,  (3,-1)  and (0,-4/3) are true values of the equation

Step-by-step explanation:

Answer:

12 units

Step-by-step explanation:

Given that :

R(-3,2)

S(2,2)

T(2,-5).

The total length ;

Distance between two points : √[(x2 - x1)² + (y2 - y1)²]

Distance between R and S :

R = (-3,2)

S(2,2)

√[((2 - (-3))^2 + (2 - 2)^2]

Sqrt(5^2 + 0^2)

D1 = 5 units

Distance between S and T:

S(2,2)

T(2,-5).

D2 = √[(2 - 2)^2 + (-5 - 2)^2]

D2 = sqrt(0^2 + (-7)^2)

D2 = 7 units

Hence, total length = D1 + D2 = (5 + 7) = 12 units

Answer:

-25 or Option B

Step-by-step explanation:

So, to solve this we will convert to an exponential form.

sqrt2 is 2 ^ 1/2

so,

3sqrt (-125)

is -125^ 1/3

Then, we factorize.

-25*3^1/3.

-25

#Team Rainbows!

Answer:

The missing value in the table would be 160.

Step-by-step explanation:

The answer is 160 because each value on the left side of the table is multiplied by 8 to get the value on the right half, so we can assume that we need to multiply 20 by 8 to get the missing value on the right.

Answer:

160

Step-by-step explanation:

Note

2 × 8 = 16

4 × 8 = 32

60 × 8 = 480

Thus

20 × 8 = 160 ← missing value
