5. london heathrow airport sees on average 191,200 passengers a day. how many passengers is this per minute?

what's the question here?

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
