0 represent the sea surface since the dolphin jumped from five feet below the sea surface and since Jane put that the dolphin jumped at -5 below the sea surface that would mean that 0 must represent the sea surface.

Find an equation of the tangent line to the hyperbola y = 3/x at the point (3, 1).
Vesna [10]
Let's find the derivative of that hyperbola in order to find a slope formula to help us with this equation.  We already have an x and y value.  The derivative is found this way:  y'= \frac{x(0)-3(1)}{x^2} so  y'=- \frac{3}{x^2}.  The derivative supplies us with the slope formula we need to write the equation.  Sub in the x value of 3 to find what the slope is: y'=- \frac{3}{3^2}=- \frac{3}{9}=- \frac{1}{3}.  So in our slope-intercept equation, x = 3, y = 1, and m = -1/3.  Use these values to solve for b.  1=- \frac{1}{3}(3)+b  so b = 2.  The equation, then, for the line tangent to that hyperbola at that given point is y=- \frac{1}{3}x+2

Umnica [9.8K]

Answer:

It would roll in this direction.

\nu  =  (-a/\sqrt{a^2+b^2},-b/\sqrt{a^2+b^2})

Step-by-step explanation:

It would roll to the direction of maximum decrease, which is the -1 times the direction of maximum increase, which is given by the gradient of the function.  

Since  

z =  ax^2  + by^2

For this case, the gradient of your function would be

\nabla z  = (2ax , 2by)

And  -1  times the gradient of your function would be

-\nabla z  = (-2ax , -2by)\\

Then, at

 (1,1,a+b),\\x = 1 \\y = 1

So it would go towards

v = (-2a,-2b)

The magnitud of that vector is

|v| =  2\sqrt{a^2+b^2}

and to conclude it would roll in this direction.

\nu  =  (-a/\sqrt{a^2+b^2},-b/\sqrt{a^2+b^2})
