Perpendicular to y = 3x + 4 through (0, -2)

1 answer:

7 0

If a line is perpendicular, is has a negative reciprocal slope
The slope for the new line will be -1/3x
To find b, plug in what you know
-2=-1/3(0)=b
-2=b
Now you have everything that you need
your line is y= -1/3x - 2
Hope this helps!

Find a vector function, r(t), that represents the curve of intersection of the two surfaces. the paraboloid z = 7x2 + y2 and the

Akimi4 [234]

Letting $x=t$ , we get $y=3x^2=3t^2$ and $z=7x^2+y^2=7t^2+(3t^2)^2=7t^2+9t^4$ , so we can parameterize the intersection by

$\mathbf r(t)=\langle t,3t^2,7t^2+9t^4\rangle$

where $-\infty$ .
