Answer:

A.) 6r

coefficient = 6

variable = r

B.) 20n

coeffect = 20

variable = n

C.) y

coefficient = 1

variable = y

D.) 9trx

coefficient = 9

variable = t, r, and x

Step-by-step explanation:

Coefficient = represented by a number

Variable = represented by a letter

For the third one y is the same as 1y therefore y has a coefficient of 1

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