Question

show that the line y=3x+1 is tangeny to the parabola
y^{2} =12x

Answer #1

Hope it will help :)

1)
Find the equation of the line that psses through the vertex if the
parabola f(x)=2x^2-12x+19 and that crosses the x-axis at x=5
2) Find the equation of the line that passes through the
certex of the parabala f(x)=3x^2-12x+17 and has y-intercept of
(0,10)

the parabola y^2=12x is shifted up 2 units and left 3 units.
find an equation for the new parabola, and find the new vertex,
focus, and directions

Find the vertex, focus and directrix of the following parabola
and sketch its graph
y+12x-2x^2=16

Find the center and radius of the circle with the equation
x2 +12x=y−y2 −24.

The equations of three lines are given below Line 1: y=3x-5 Line
2: y=-1/3x +1 Line 3: 3x-9y=18 For each pair of lines, determine
whether they are parallel, perpendicular, or neither: 1. Line 1 and
2 are they (parallel, perpendicular, or neither.) 2. Line 1 and 3
are they (parallel, perpendicular, or neither.) 3. Line 2 and 3 are
they (parallel, perpendicular, or neither.

Find the coordinates of the centroid of the region bounded by
y=12x^2 and y=3x^3. The region is covered by a thin flat plate.

Show that the curve y =
4ex +
3x + 2x3 has no
tangent line with slope 2.
y'=
y'= ? (< = >) 2, so no tangent line can
have slope 2.

Sketch the central field F = (x /(x2 +
y2)1/2)i + (y /(x2 +
y2)1/2) j and the curve C consisting of the
parabola y = 2 − x2 from (−1, 1) to (1, 1) to determine
whether you expect the work done by F on a particle moving along C
to be positive, null, or negative. Then compute the line integral
corresponding to the work.

Given z = (3x)/((x2+y2)1/2) ,
Find ∂z/∂x and ∂z/∂y.

Show that the curve y = 3x^3 + 8x − 2 has no tangent line with
slope 3
