Answer: y = -3x + 10
Step-by-step explanation:
Using the formula for finding the equation of line ;
y - = m ( x -
)
= 4
= -2
m = -3
Substituting into the formula , we have
y - (-2) = - 3 ( x - 4 )
y + 2 = -3x + 12
writing the equation of the line in slope - intercept form , this means that we must make y the subject of the formula , that is
y = -3x + 12 - 2
y = -3x + 10
The approximation of the circumference of the ride is 138 feet to the nearest foot
<h3>How to determine the circumference?</h3>The given parameters are:
- Center (a,b) = (0,0) i.e. the origin
- A circular ring, (x,y) = (16,15.1)
The radius is calculated using:
So, we have:
Evaluate
r = √484.01
Evaluate the square root
r = 22.0
The circumference is calculated using
C = 2πr
So, we have:
C = 2π * 22.0
Evaluate
C = 138
Hence, the approximation of the circumference of the ride to the nearest foot is 138 feet
