How many radians does the minute hand of a clock rotate through over half an hour? How many degrees?
Ivanshal [37]

Answer:

So minute hand will rotate \pi radian in half an hour

Step-by-step explanation:

In one hour minute hand of clock rotate about 360°

So in half an hour minute hand clock rotate \frac{360}{2}=180^{\circ}

We have to find how many minute hand rotate in radian

For conversion of degree to radian we have to multiply with \frac{\pi }{180}

So 180^{\circ}=180\times \frac{\pi}{180 }=\pi radian

So minute hand will rotate \pi radian in half an hour

A line is shown in the graph below.
Kay [80]

Answer:

-3/2

Step-by-step explanation:

One can read off the slope of the given line directly from the graph.  As x increases by 3, y increases by 2.  Thus, the slope of the given line is

m = rise / run = 2 / 3

Any line perpendicular to this given line has a slope which is the negative reciprocal of the slope previously found:

                                                      -1              3

Slope of perpendicular line = ------------ = - -----

                                                     2/3             2

This matches the first of the given possible answer choices.
