Differentiate implicitly.
x^2y' + y(2x) = x(2yy') + y^2
x^2y' + 2xy = 2xyy' + y^2
x^2y' - 2xyy' = y^2 - 2xy
y'(x^2 - 2xy) = y^2 - 2xy
y' = (y^2 - 2xy)/(x^2 - 2xy)</span><span />
Answer:
18.85 feet
Step-by-step explanation:
Determine the arc length of SR
Arc length = θ/360 × 2πr
r = 9 feet
θ =120°
Arc length = 120/360 × 2 × π × 9
= 18.849555922 feet
Approximately = 18.85 feet
Therefore, the arc length of SR = 18.85 feet
20/2=10 because the formula for acceleration is velocity or speed (20) divided by time (2)
2x + 6 = -2x - 2 equation
X = -2 solution
