Answer: 6.8571 (Round as needed)

Hope this is correct

Step-by-step explanation:

This is a simple ratio problem

Using the similarity statement we can say 14:12, (ab:pq)

That is our ratio.

So we do 14/12 = 8/x, we solve this using algebra to get our answer.

Hope this is correct.

The parametric curve described by the equations x=\cos(t),\;\;y=\sin(t)\cos(t) has two tangent lines at (0, 0). find the equatio
mr Goodwill [35]
Hello,

x=cos(t)==\ \textgreater \  \dfrac{dx}{dt} =-sin(t)\\
y= \dfrac{sin(2t)}{2}==\ \textgreater \  \dfrac{dy}{dt} =cos(2t)\\

 \dfrac{dy}{dx} = \dfrac{ \frac{dy}{dt}}{ \frac{dx}{dt} } =- \frac{cos(2t)}{sin(t)} \\
For\ x=0, \ t=cos(0)= \frac{ \pi }{2} +k \pi \\

( \dfrac{dy}{dx} )_{x=0} =\pm\ 1\\

tangents \ are\ \{ y=-x,y=x \}\\
