Answer:

-24

Step-by-step explanation:

-4-8= -12

8-2=6

12+6=18

-12b+6c+18

Greatest common factor = 6

-12/6=-2

6/6=1

18/6=3

D 6(-2b+1c+3)

-12(2)+6(-3)+18

-24+(-18)+18

Answer:

$y=-\dfrac{1}{2}(x+4)^2-1$

Step-by-step explanation:

Vertex form: $y=a(x-h)^2+k$

where:

$(h, k)$ is the vertex
$a$ is some constant

Given:

vertex = (-4, -1)
point on parabola = (-2, -3)

Substitute given values into the formula to find $a$ :

$\implies -3=a((-2)-(-4))^2+(-1)$

$\implies -3=a(2)^2-1$

$\implies -3=4a-1$

$\implies -2=4a$

$\implies a=-\dfrac{2}{4}=-\dfrac{1}{2}$

Therefore, the equation of the parabola is:

$y=-\dfrac{1}{2}(x+4)^2-1$

postnew [5]

Answer:

69.08cm

Step-by-step explanation:

The formula for the circumference is

pi times diameter=circumference
