A race track is made up of a rectangle shape 750 m by 500 m semi circles at each end. Marisol drives the track once at average s
Mkey [24]

Answer:

d=3071m

Step-by-step explanation:

From the question we are told that:

Dimension Of rectangle

Length l=750m

Breath b=500m

Velocity v=140kmh

Generally the equation for distance travel by Marsol once round the Circle is is mathematically given by

 d=2(l)+2(arc\ of\ the\ semi\ circle)

 d=2(l)+2( 2\pi r (\frac{\theta}{360}))

Where

 r=\frac{b}{2}

 r=\frac{500}{2}=>250

And

 \theta=180

Therefore

 d=2(750)+2( 2\pi 250 (\frac{180}{360}))

 d=3071m

(√x+1/√x)^2find dy/ dx and substitute 2 in dy/ dx
lions [1.4K]
Hello,
That's better.

I suppose y=( \sqrt{x} + \dfrac{1}{ \sqrt{x} } )^2 \\

y'=2*( \sqrt{x} + \dfrac{1}{ \sqrt{x} } )*( \dfrac{1}{2 \sqrt{x} } - \dfrac{3}{2x \sqrt{x} } )

If x=2  then
y'=2*( \sqrt{2} + \dfrac{1}{ \sqrt{2} } )*( \dfrac{1}{2 \sqrt{2} } - \dfrac{3}{2*2* \sqrt{2} } )\\
=2* \dfrac{2+ \sqrt{2} }{ \sqrt{2} } * \dfrac{1}{4*\sqrt{2} } *(-1)\\
=- \dfrac{2+ \sqrt{2} }{4}
