In order to be continuous everywhere, we only need to satisfy continuity at
. For that to happen, we need to have

By the function's definition,
. Compute the limits:


So we must have

#3)NO
#4)9 x 15 divided by 6
answer=$22.5
#5)25 x 5 divided by 1
answer=125miles
#6)2:20=1:10
P = 60 meters
l = 4 meters
60 / 4 = 20 <-- Because retangles have 4 sides.
If l=4 then subtract 4 from 20
So w=16
