Answer:

A Jeff is faster than Cameron.

Step-by-step explanation:

Given

Jeff = 7km/hr

Cameron = 100m/min

Required

Which is faster

To do this, we simply convert both to the same unit.

We have:

Jeff = 7km/hr

Convert to m/min

1km \to 1000m; 1hr \to 60min

So:

Jeff = \frac{7 * 1000m}{1 * 60min}

Jeff = \frac{7000m}{60min}

Jeff = 117\ m/min

Recall that: Cameron = 100m/min

By comparison:

117m/min > 100m/min

<em>Hence, Jeff is faster.</em>

For which value of theta is sin theta equals -1?
Olin [163]

Answer:

The value of Ф is 3π/2

Step-by-step explanation:

* Lets revise the angle Ф in the four quadrant

∵ r = √(x² + y²) ⇒ square the two sides

∴ x² + y² = r²

∵ r = 1

∴ x² + y² = 1

∵ cos² Ф + sin² Ф = 1

∵ x is the adjacent side to Ф and y is the opposite side to Ф

∴ x = cos Ф and y = sin Ф

- At point (1 , 0)

∵ x = 1 , y = 0

∴ cos Ф = 1 and sin Ф = 0

∵ The positive part of x-axis represents the angle 0 and 2π

∴ cos 0 and 2π are 1 and sin 0 and 2π are 0

- At point (0 , 1)

∵ x = 0 , y = 1

∴ cos Ф = 0 and sin Ф = 1

∵ The positive part of y-axis represent the angle π/2

∴ cos π/2 is 0 and sin π/2 is 1

- At point (-1 , 0)

∵ x = -1 , y = 0

∴ cos Ф = -1 and sin Ф = 0

∵ The negative part of x-axis represents the angle π

∴ cos π is -1 and sin π is 0

- At point (0 , -1)

∵ x = 0 , y = -1

∴ cos Ф = 0 and sin Ф = -1

∵ The negative part of y-axis represent the angle 3π/2

∴ cos 3π/2 is 0 and sin 3π/2 is 1

* For the value of Ф = 3π/2 is sin Ф = -1
