Which equation has a graph that is a parabola with a vertex at (–2, 0)? y = –2x2 y = (x + 2)2 y = (x – 2)2 y = x2 – 2

B)  y =  (x+2)².

Step-by-step explanation:

Given  : parabola with a vertex at (–2, 0).

To find  : Which equation has a graph .

Solution : We have given that vertex at (–2, 0).

vertex form of parabola : y = a (x-h)²+k

Where vertex (h , k)

Plugging the values h = -2 , k=  0 a = 1

y = (x-(-2))²+0

y =  (x+2)².

Therefore, B)  y =  (x+2)².

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
