Answer:

y = -3/8(x + 2)^2 + 8

Step-by-step explanation:

vertex form is

y = a(x - b)^2 + c     where a is a constant and (b,c) is the vertex.

The maximum is at (-2, 8)  because x 8 = height and x =-2 is equn. of symmetry

So here we have

y = a(x - (-2))^2 + 8

y = a(x + 2)^2 + 8

Now at the point (-6, 2):

2 = a(-6+2)^2 + 8

2 = 16a + 8

16a = -6

1 = -3/8.

So our equation is y = 3/8(x + 2)^2 + 8

Last year, 210 middle school students
Anit [1.1K]

Answer:

8%

Step-by-step explanation:

let,

this year population of students (pt)= 195

last year population of students (p)= 210

time(t)= 1 year

Population Change( R)= ?

we have,

pt= p( 1 - R/100)^t

195 = 210 ( 1 - R/100)^1

0.92= 1 - R/100

0.92-1= R/100

- 0.08 = - R/100

R= 0.08×100

R= 8%
