Name the ordered pair that corresponds to an angle of a pi radians
olga2289 [7]

Answer:

3π (540°) and 5π(900°)

Step-by-step explanation:

π radian = 180° degree

in the trigonimitrical cercle each point is taken by many values

so π position is also -π position

to move from π to -π you should move 360° (wich is 2π) backwards

π-2π = π

so  -π = π +2π

you can get as much as you can of values similar to π using the formula :

π + 2*k*π where k is a relative number

  • k=1

π+ 2*1*π = 3π

  • k=2

π+2*2*π = 5π

3π is 540°

5π is 900°

In 2005, a Nevada silver mine exported 200 tons of silver. In 2008, as the silver supply became exhausted, it only exported 25 t
yulyashka [42]
To obtain the rate of change of mine's silver output, subtract the number of silver exported on 2005 from that on 2008. From the given, from 2005 to 2008, which is a span of 3 years, the exported silver decreased by 175 tons. Thus, the rate of change is equal to -175 tons per 3 years.

How many 1/5 pieces are in 4/5
Alla [95]

Answer:

4

Step-by-step explanation:

Take 1/5 divided by 4/5.  In order to divide fractions you take the problem:

(4/5)/(1/5)

Then you flip the second fraction and multiply:

4/5 x 5/1

20/5

4

You could also just divide 4 by one, since the two fractions have the same denominator
