Answer:
x=3.414 and x=0.59 is the desired answer.
Step-by-step explanation:
We are given a quadratic equation as :
on dividing both side by 2 we have the equation as
on solving for the roots of the equation using the quadratic formula we get that
and
x=2+1.414 and x=2-1.414
Hence , x=3.414 and x=0.586≈0.59.
Answer:
Step-by-step explanation:
Suppose the radius is 1. The parametric equations for the circle are
x = cosθ
y = sinθ
x:y = 3:1
tanθ = ⅓
cosθ = 3/√(1²+3²) = 3/√10
sinθ = 1/√10
The solutions are (3/√10, 1/√10) and (-3/√10, -1/√10).
