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

Answer:

1.5 meters = 150 centimeters (multiply by 100)

Therefore, you should cut off $225-150=75$ centimeters.

Please help! I will give brainliest! Needed ASAP!!

attashe74 [19]

step-by-step explanation:

since it tells you the equation 'y = 20x' and y is the number of gallons where as x is minutes

the independent variable = number of gallons

the dependent variable = minutes

and the number(s) to fill in the table

x , y

( 0, 0 )

( 1, 20 )

( 2, 40 )

( 3, 60 )

( 4, 80 )

and the relationship between x and y is linear because you can clearly see the graph having especially a straight line that is not interfering with itself

hope this helps you! :)
