Answer:
y = (x-1)^2 - 2
Step-by-step explanation:
The parabola vertex point is always (h, k) in y = (x-h)^2 + k
All you have to do is look at h and k to find your vertex. Since in y = (x-1)^2 -2 has an h of -1 (Which makes it positive 1 when you plug it in) and a k of -2, that means that is your answer.
Answer:
Step-by-step explanation:
If John charge $12 then he has 14 students, and he gets $ 14*12,
If he increases on $2(12+2) , he loses 1 student (14-1), gets (12+2)*(14-1)
if he increases on he loses 2 students (14-2) gets (12+2*2)(14-2)
2+2 (12+2*2)
if he increases 2*3 he loses 3 students, (14-3) gets (12+2*3)(14-3)
2x*3 (12+2*3)
and so on......
if he increases 2*x, he loses x students, (14-x)left, gets (12+2x)(14-x)
(12+2x)
So , his revenue in general =
(12+2x)(14-x)=12*14-12x+28x-2x²=-2x²+16x+168
<em> I think it should look like this
</em>c(x)= -2x²+16x+168
29,000 kph x 24 hours = 696,000 kilometers
696,000 km = 6,960,000 hectometers
3x + 20 = 40 + 40
3x = 60
X = 20
V + 71 = 107
V = 36
