Y = ( x - 3 )² + 4
Vertex of the parabola: ( 3, 4 )
y = - x + b
4 = - 3 + b
b = 7
Equation 2: y = - x + 7
( x - 3 )² + 4 = - x + 7
x² - 6 x + 9 + 4 = - x + 7
x² - 5 x + 6 = 0
x - 2 x - 3 x + 6 = 0
x ( x - 2 ) - 3 ( x - 2 ) = 0
( x - 2 ) ( x - 3 ) = 0
x 1 = 2, x 2 = 3
y 1 = 5, y 2 = 4

The volume of the cylinder increases by a factor of 
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
------> original volume
In this problem
substitute in the formula
therefore
The volume of the cylinder increases by a factor of
<b = 60/2 = 30

Lovely.
The car is traveling at 95 km/h, and the train is at 75 km/h.
Remember the train is 1 km long.
a)
With respect to the train the car is not moving as much as 75 km/h.
The car with respect to the train is moving as much as 95 - 75 = 20 km/h
Recall the train is 1 km long.
Time to cover the 1km long train = Distance / speed = 1 / 20 = (1/20) hour.
= (1/20)*60 minutes = 3 minutes.
So the car would pass the train in 3 minutes.
b)
Now if they are traveling in opposite directions;
the car with respect to the train = 75 + 95 = 170 km/h
Time to cover the 1km long train = Distance / speed = 1 / 170 = (1/170) hour.
<span>= (1/170)*60 minutes = (6/17) minutes
</span>
= (6/17)*60 seconds = 360/17 seconds ≈ 21.176 seconds.
