Answer:

Part 1) The vertex is the point (-2,-4)

Part 2) The axis of symmetry is equal to x=-2

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

y=a(x-h)^{2}+k

where

(h,k) is the vertex of the parabola

The axis of symmetry of a vertical parabola is equal to

x=h ----> the x-coordinate of the vertex

In this problem we have

y=2(x+2)^{2}-4

The vertex is the point (-2,-4)

The axis of symmetry is equal to the coordinate of the vertex

so

x=-2

see the attached figure to better understand the problem

The product of 2 consecutive positive odd integers is 483. Write the equation that would be used to find x, the smaller integer.
Montano1993 [528]

Answer: 21

Step-by-step explanation:

Let the consecutive odd numbers be represented by x and x+2. Therefore,

x × (x+2) = 483

x² + 2x = 483

x² + 2x - 483 = 0

x² + 23x - 21x - 483 = 0

x(x + 23) - 21(x + 23) = 0

(x - 21) = 0

x = 0 + 21

x = 21

The smaller integer is 21

The larger integer is 21 + 2 = 23.

Chef Rita is cooking for a Sunday brunch. She knows that 22 pancakes can feed 8 people. She is wondering how many people left pa
defon
Chef Rita can feed 20 people.

Explanation:
If 22 pancakes can feed 8 people, then 11 pancakes can feed 4 people (divide both by 2). Since 55 is 11x5, you multiply 4 times 5 to get 20.

Hope this helps!

Sabeena had 15 3/4m long ribbon. She cut into two pieces such that the length of one pieces is 9 1/2m. Find the length of other
DochEvi [55]

Answer:

6 1/4

Step-by-step explanation:

Total length of the ribbon= 15 3/4 m= 63/4 m

One piece= 9 1/2 m= 19/2 m

Other piece length =X

X= 63/4-19/2

  =63/4-38/4

  =25/4

  =6 1/4

A = (pi) * r*2
(pi) = 3.14
r = d/2.....r = 17/2 or 8.5

A = 3.14 * 8.5^2
A = 3.14 * 72.25
A = 226.86 rounds to 226.9 m^2 <==
