The enrollment drop per year is 12 students
Problem
Solution
For this case we know that the vertex is given by (3,6) and the genera equation for a parabola is given by:
y= a(x-h)^2 +k
Where h = 3, k=6 and replacing we have:
y= a(x-3)^2 +6
And we can find the value of a with the point given x= 4, y=4
4= a(4-3)^2 +6
4= a +6
a= 4-6=-2
And the correct equation would be:
d. y= -2(x-3)^2 +6
Answer:
9 years.
Step-by-step explanation:
For 50 raccoons the equation is
0.4x^2+2x+2 = 50
0.4x^2+2x - 48 = 0
x = [-2 +/- sqrt(2^2- 4* 0.4*(-48)] / (2*0.4)
= (-2 +/- sqrt 9) / 0.8
= 8.74 , - 13.75 (ignore the negative).
So it's 9 years.
