After 3 hours of work a farmer has harvested 480 fruits. After 5 hours he harvested 550 fruits. Is this a proportional relationship?

No

Step-by-step explanation:

480 fruits/3 hours=160 fruits/hour average

550 fruits/5 hours=110 fruits/hour average

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
