If -xy – 5+ y^2+ x^2= 0 and it is known that dy/dx= y-2x/-x+2y, find all
sleet_krkn [62]

Answer:

There is no point of the form (-1, y) on the curve where the tangent is horizontal

Step-by-step explanation:

Notice that when x = - 1. then dy/dx becomes:

dy/dx= (y+2) / (2y+1)

therefore, to request that the tangent is horizontal we ask for the y values that make dy/dx equal to ZERO:

0 = ( y + 2) / (2 y + 1)

And we obtain y = -2 as the answer.

But if we try the point (-1, -2) in the original equation, we find that it DOESN'T belong to the curve because it doesn't satisfy the equation as shown below:

(-1)^2 + (-2)^2 - (-1)*(-2) - 5 = 1 + 4 + 2 - 5 = 2  (instead of zero)

Then, we conclude that there is no horizontal tangent to the curve for x = -1.

Answer:

<h3>{44-55}</h3><h3>{52- 59 } are the last two interval s</h3>

Step-by-step explanation:

<h2>To get the class boundaries deduct 0.5 from the first number and add 0.5 to the second number = 4-0.5 = 3.5 </h2><h2> = 11.5 + 0.5 = 11.5 </h2><h2> = 3.5 -11.5 as in the fish class boundary .</h2><h2>same for all other boundaries</h2>

The cost of fencing a square field at Rs.15 per meter is Rs.360. Find the length of each side of the field.
torisob [31]

Answer:

The lenght of one side= 6

Step-by-step explanation:

The cost of fencing around the field for one meter =  15

The total cost = 360  

The perimeter = 360 / 15 = 24 m

The lenght of one side= 6

( p = 4S)

so .... (s = p /4 )

24 = 4s

so .... s = 24/4 = 6

I hope it's right !!!!!
