Going around a full circle is 360.
1/4 of that is 90
So 90 degrees is 1/4 of a circle
Circumference of a cirlce=2πr
Data:
r=7 in
Circumference=2(3.141592....)(7 in)=43.9822...in≈44 in.
Answer: 44 inches.
y=5/3x
this is because f(x)=x is one of (identity function) the 12 basic functions and when you multiply it it will shift it on the y axis
If you were to do y=x+5/3 it would make a horizontal shift to the left 5/3
So the unit your on is mostly about knowing the number located in the function that will make the graph shift different ways
