1 answer:
Y=3(x²+10x)+71
Now we need to complete square for (x²+10)
It should look like this
a²+2ab+b²=(a+b)²
y=3(x²+2*5x+5²)-3*5²+71
y=3(x+5)²-75+71
y=3(x+5)²-4
Vertex has coordinates x=-5, y=-4.
Vertex in this case is the extreme value (-5,-4)

C=pi(radius)^2
c=pi(5)^2
c=pi(25)
c=78.5398163397...
c is about 78.5

We need to convert 45 min to hours.
There are 60 min in an hour.
45/60 = 0.75
45 minutes = 0.75 hour
(4 km)/(0.75 h) = 5.3333 km/h = 5 1/3 km/h
