Kobotan [32]

Answer:

$10^3$ times

Step-by-step explanation:

Given

Let

$P \to$ Park Crest Middle School

$T \to$ Total

So, we have:

$P = 400$

$T = 406240$

Required

Determine the number of times T is greater than P

This is calculated by dividing T by P.

i.e.

$n = \frac{T}{P}$

So, we have:

$n = \frac{406240}{400}$

$n = 1015.6$

Approximate

$n \approx 1000$

As a power of 10, we have:

$n = 10^3$

F(t) = t2 + 4t − 14

y + 14 + 4 = ( t2 + 4t +4)

y + 18 = ( t + 2)^2

so the vertex of the parabola is ( -2 , -18)

<span>the axis of symmetry is y = -18</span>
