Mathematics

g100num [7]3 years ago
8 0
Ln(xy) - 2x =0

slope of the tangent line = derivative of the function

[ln(xy)]' = [2x]'

[1/(xy)] [y + xy'] = 2

y + xy' = 2(xy)

xy' = 2xy - y =y(2x-1)

y' = y(2x-1)/x

Now use x = -1 to find y and after to find y'

ln(xy) = 2x
x=-1
ln(-y) =-2

-y = e^-2

y = - e^-2

y' = [-e^-2][2(-1)-1]/(-1) = [e^-2](-2-1)= [e^-2](-3) = - 3e^-2

Answer: option 6. from the list

fiasKO [112]
Easy I guess ..
I ll try to help ..
Here we go ..
The cards you have is N
The cards he has is n
<span>you have 3 times the number of cards he has
This means N=3n
</span><span> you only have 80 more football cards then he does
This means N=n+80
But we already know that N=3n
So 3n=n+80
which is 2n=80
n=40
So your friend has only 40 cards and you have 3*40= 120 cards

Best luck

The equation X squared plus Y squared minus 2X plus 7Y +1 equals zero can be written as which of the following equations
ad-work [718]

For this case we must write in algebraic symbology the expression described above:

We have an equation, then:

  • x squared plus y squared: x ^ 2 + y ^ 2
  • minus 2x plus 7y plus 1: -2x + 7y + 1
  • equals zero: = 0

We construct the equation:

x ^ 2 + y ^ 2-2x + 7y + 1 = 0

Answer:

x ^ 2 + y ^ 2-2x + 7y + 1 = 0

Lenny is planning to cut down a pine tree. He has parked his truck 90 feet away from the base of the tree and wants to make sure
Veronika [31]

Well, if the elevation is 45 degrees, the height of the tree and the distance to the truck are the same.


The elevation is more than that, so the distance to the truck is less than the height of the tree. 


The only answer that reflects that is D.
