Answer:

1. y = 6x

2. y = 5x

Step-by-step explanation:

the first is y = 6x because when the x value increases by 1, the y value increases by 6

the second one is y = 5x because when the x value increases by 1, the y value increases by 5 and there isn't a y-intercept so the line goes through the origin

The table would be y = 6x

Divide the Y values by the X values and they all equal 6, so you multiply the X value by 6 to get y.

Look at the dots on the graph ( 1,5) (2,10) (3,15) (4,20)

Divide the Y value by the X and they all equal 5, soy = 5x

Suppose a tub has the shape of an elliptical paraboloid given by z = ax2+by2 (where a, b are some positive constants). If a marb
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})
