serg [7]

Answer:

Option (B)

Step-by-step explanation:

To calculate the distance between C2 and SW1 we will use the formula of distance between two points (x_1,y_1) and (x_2,y_2).

d = \sqrt{(x_2-x_1)^{2}+(y_2-y_1)^2 }

Coordinates representing positions of C2 and SW1 are (2, 2) and (-6, -7) respectively.

By substituting these coordinates in the formula,

Distance between these points = \sqrt{(-6-2)^2+(-7-2)^2}

                                                     = \sqrt{(64)+(81)}

                                                     = \sqrt{145} units

Therefore, Option (B) will be the correct option.

Read the problem.
Alexandra [31]

Step-by-step explanation:

D= 56t

D= 60t -2

D= Distance T=time d = 56t (Jordan) d = 60t - 2 (Roman)

d = 56t d = 60t - 2

56t = 60t - 2 d = 56(1/2) d = 60(1/2) - 2

-60t -60t d = 28 d = 30 - 2 = 28

-4t = -2

t = 1 / 2

Find the exact value of the trigonometric function
velikii [3]

Answer:

2  

Step-by-step explanation:

Step 1. <em>Find a coterminal angle that falls be 0 and 2π. </em>

Remember that cscθ is a periodic function. It repeats every 2π radians.

If n is an integer, cscθ = csc(θ ± 2πn)

csc(17π/6) = csc(12π/6 + 5π/6)

                = csc(2π + 5π/6)

                = csc(5π/6)

Step 2. <em>Use the unit circle to evaluate cscθ. </em>

cscθ = 1/sinθ

Let θ = 5π/6

In a unit circle (below), the sine of an angle is y.

sinθ = ½

cscθ = 1/sinθ

        = 1/(½)

        = 2
