You can use the degree measure of the central angle theta (the number of degrees you have gone around the circle) and the amount of radians you have gone around the circle
the equation for arc length using degrees and radians is: s(arc length) = r(xº)
r is not the radius length it is the length you have gone around the circle measured in terms of the radius
you need to know the central angle (degrees) and radians to figure out arc length without knowing the radius length
The answer for ure question is x<-1/2

Formula
V= c(1-r)^t
V= future value
C= current value
r= depreciation rate p/yr
t= number of periods
v = 20500*(1-0.16)^8
v =
Answer:
x = 0
Step-by-step explanation:
This is a vertical line, in fact the y- axis
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through
All of the x- coordinates on the y- axis are zero, then
x = 0 ← equation of line
