Answer:
L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt
Step-by-step explanation:
Arc length of a parametric curve is:
L = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt
x = t + cos t, dx/dt = 1 − sin t
y = t − sin t, dy/dt = 1 − cos t
L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt
Or, if you wish to simplify:
L = ∫₀²ᵖⁱ √(1 − 2 sin t + sin²t + 1 − 2 cos t + cos²t) dt
L = ∫₀²ᵖⁱ √(3 − 2 sin t − 2 cos t) dt

Hello.
Multiply all terms by x and cancel:
x2x+1=18x
x3+1=18x(Simplify both sides of the equation)
x3+1−18x=18x−18x(Subtract 18x from both sides)
x3−18x+1=0
(Use cubic formula)
x=−4.27015,0.055565,4.214585
Check answers. (Plug them in to make sure they work.)
x=4.214585(Works in original equation)
x=−4.27015(Works in original equation)
x=0.055565(Works in original equation)
So the answer is: 4
Have a nice day
Answer:
zeros are ±2
Step-by-step explanation:
y = x² - 4
this can be factored into (x+2)(x-2)
if you then set each factor equal to zero you will get zeros of ±2
