Suppose measures the minimum angle between a clock’s minute and hour hands in radians. what is theta′ at 4 o’clock? give your answer in radians per minute. (use symbolic notation and fractions where needed.)

radians per minute.

Step-by-step explanation:

In order to solve the problem you can use the fact that the angle in radians of a circumference is 2π rad.

The clock can be seen as a circumference divided in 12 equal pieces (because of the hour divisions). Each portion is

So, you have to calculate the angle between each consecutive hour (Let ∅ represent it). It can be calculated dividing the angle of the entire circumference by 12.

∅=

Now, you have to find how many pieces of the circumference are between 12 and 4 to calculate the angle (Because 4 o'clock is when the minute hand is in 12 and the hour hand is in 4)

There are 4 portions from 12 to 4, so the angle (Let α represent it) is:

α=

But the answer is asked in radians per minute. So you have to divide the angle by the amount of minutes between the hands of the clock at 4 o'clock.

There are 60 divisions in a clock for representing minutes, therefore in every portion there are:

minutes

So, from the 12 mark to the 4 mark there are 20 minutes

The angle per minute is:

α= rad/min

Notice that the minimum angle is the angle mesured clockwise.

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
