Samuel fell asleep after they had travelled 90 miles. if the total length of the trip was 600 miles, what percentage of the total trip had they travelled when samuel fell asleep?

Step-by-step explanation:

The total length of the trip = 600 miles

Samuel fell asleep after they had travelled  = 90 miles

Percentage of the total trip travelled when samuel fell asleep =

= 15%

Samuel fell asleep after travelling 90 miles which is 15%of their total trip distance.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

sorry i just need to anwers this to get points
