What is the focus of the parabola? y=−14x2−2x−2 Enter your answer in the boxes.

Sloan [31]

Answer:

Step-by-step explanation:

Given is a parabola

$y=-14x^2-2x-2$

Let us rewrite this in vertex form

$y=-14(x+\frac{1}{14})^2-\frac{27}{14}$

Hence vertex = $(\frac{-1}{14} ,\frac{-27}{14} )$

Axis of symmetry is

$x=-\frac{1}{14}$

a= $\frac{1}{(14)4} =\frac{1}{56}$

Hence focus would lie on the line of symmetry at a distance of a from vertex

So focus = $(-\frac{1}{14} ,-\frac{27}{14} -\frac{1}{56} )\\=(-\frac{1}{14} , -\frac{109}{56} )$

triangle hij had a vertices of h (1,7),I(-4,-2),j(-3,5) write the coordinate notation for a translation of 3 units to the right

yanalaym [24]

The coordinates are H'(4,11), I'(-1,2), J' (0,9).

Step-by-step explanation:

Triangle HIJ had a vertices of h(1,7), i(-4,-2), j(-3,5)

Here we are going to translate the pre-image.

Translation up means we have to add the translated units to the y-coordinate of the (x,y) point of the preimage.

Translation to the right means we have to add the translated units to the x-coordinate of the (x,y) point of the preimage.

So the points of the image have the change in points using the translation as,

(x+3, y+4)

So the points of the triangle may be changed as,

H (1,7) → H'(1+3, 7+4) → H'(4,11)

I (-4,-2) → I' (-1,2)

J (-3,5) → J' (0,9)

What is the volume of this cylinder? 6m, 7m

FrozenT [24]

Answer:

$198\:\mathrm{m^3}$

Step-by-step explanation:

The volume of a cylinder is given by $V=r^2\pi\cdot h$ , where $r$ is the radius of the cylinder and $h$ is the height.

What we're given:

$r$ of 3
$h$ of 7

Substituting given values, we get:

$V=3^2\pi\cdot 7,\\V=9\cdot 3.14\cdot 7,\\V\approx 197.82\:\mathrm{m^3}=\boxed{198\:\mathrm{m^3}}$ , rounded the nearest cubic meter as requested in question.
