The sprinkler turns through 3/4 of the circle. what is the measure of the angle it turns through?

270 degrees because 1/4 of a circle is 90 degrees

Step-by-step explanation:

Since the angle measure of a full circle is 360 degrees, find 0.75 of 360.

The measure of the angle the sprinkler turns through is 270 degrees.

Another way to do this would be to take 1/4 of a circle, 90 degrees, and multiply it by 3!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
