Answer:

C. 8

Step-by-step explanation:

The elevator goes up 51 floors in 12.75 seconds.

Take 51/12.75 to get the number of floors per second.

51/12.75=4

4 floors multiplied by 2 seconds equals 8.

Therefore, answer C is correct.

Answer:

  sin(θ) ≈ -0.92

  cos(θ) ≈ 0.38

  tan(θ) = -2.40

Step-by-step explanation:

Let r represent the distance of the point from the origin. The Pythagorean theorem tells us ...

  r² = (5)² + (-12)²

  r² = 169

  r = √169 = 13

The trig relations for a point on the terminal ray are ...

  (x, y) = (r·cos(θ), r·sin(θ))

Then ...

  sin(θ) = y/r = -12/13 ≈ -0.92

  cos(θ) = x/r = 5/13 ≈ 0.38

  tan(θ) = y/x = -12/5 = -2.40
