Answer:

A circle is the set of all points in a plane equidistant from a given point.

Step-by-step explanation:

A circle is a shape composed of a single line or set of points that have the same distance from the center of the circle or that are equidistant from the center.

Plsssssssssssssssssssssssssssssss help

Semenov [28]

Answer:

Solution,

<ABE+<ABC=180

<ABE=180-97

<ABE=83°

<ABC=<ACB=83°

<ABC+<ACB+<CAB=180

<CAB=180-83-83

<CAB=14

<DAC+<CAB=180

<DAC+14=180

<DAC=180-14

<DAC(X)=166°

Hope this helps...

Good luck on your assignment...

PLEASE FIND THE VERTEX OF THIS PARABOLA

yarga [219]

Given equation of the parabola y= -5x^2 -10x -13.

We need to apply formla for x-coordinate of the vertex.

x=-b/2a.

For the given equation we have a=-5 and b=-10.

Plugging values of a and b in formula of x-coordinate of the vertex.

x= -(-10)/2(-5)

x= 10/(-10) = -1.

So, we got x-coordinate of the vertex = -1.

Now, we need to plug x=-1 in given equation to find the y-coordinate of the vertex.

Plugging x=-1 in y= -5x^2 -10x -13, equation we get

y=-5(-1)^2-10(-1)-13.

y= -5(1) +10 -13.

y=-5 +10-13.

y=-18+10.

y=-8.

So, we got y-coordinate of the vertex -8.

Therefore, vertex of the parabola is (-1,-8).

HELP!Please solve! this!!

Answer:

Recursive formula for geometric sequence

$a_{n}=a_{n-1}\times r$

is $a_{n}=a_{n-1}\times 6$

and explicit formula for geometric sequence $a_{n}=a_{1}^{r-1}$ is

$a_{n}=(\frac{1}{2})^{6-1}$

Step-by-step explanation:

Given sequence is $\frac{1}{2},3,18,108,648,...$

To find the recursive and explicit formula for this sequence:

Let $a_{1}=\frac{1}{2},a_{2}=3,a_{3}=18,a_{4}=108,a_{5}=648,...$

To find the common ratio r:

$r=\frac{a_{2}}{a_{1}}$

$=\frac{3}{\frac{1}{2}}$

$=3\times 2$

$=6$

Therefore r=6

$r=\frac{a_{3}}{a_{2}}$

$=\frac{18}{3}$

$=6$

Therefore r=6

Therefore the common ration r=6

Therefore the given sequence is geometric sequence

Recursive formula for geometric sequence is $a_{n}=a_{n-1}\times r$

$a_{n}=a_{n-1}\times 6$

and explicit formula is $a_{n}=a_{1}^{r-1}$

$a_{n}=(\frac{1}{2})^{6-1}$

$=(\frac{1}{2})^{5}$

$=\frac{1}{32}$

Therefore $a_{n}=\frac{1}{32}$
