In a circle, two perpendicular chords, AB of length 5.1 cm and CD of length 6.8 cm, intersect at a point P. Find the maximum possible distance from the center of the circle to P.
8.5 cms

1.7*3 and 1.7*4 and 1.7*5 are pythogorean triplets

8.5/2 =4.25
not sure
this case possible when B coincides with C

The top speed of a rail engine is 80 km/hr. When pulling a train of wagons, its top speed is reduced by a quantity proportional to the square-root of the number of wagons. When the number of wagons attached to the engine is 25, its top speed is 55 km/hr. If the top speed must be more than 20 km/hr, what is the maximum number of wagons that can be attached to the engine?
143.?

@techsurge max length will be when they both meet at the circumference..so the distance will be the radius of the circle which is 8.5/2=4.25 cm.

A fair coin is tossed n times. What is the probability that no two consecutive heads appear?

@maddy2807 yes yes cousin sister!!

thats what I am saying if they meet at center P wil coincide with B and C considering those are the meeting points
Am I thinking right :P

she is Sparsh's son aunt (bhua)
It should be cousin sis.. Paresh €™s father €™s mother would be the daughter of sparsh's bro..
and hence cousin of sparsh's son..

take n = 2

H T and T H = 2 cases

so , prob. = 1/2
5638
@jain4444 takin n = 2
HT, TH, TT = 3
prob = 3/4
now

:D
@krum rarely u make mistake, but this is out of box ques...check once

bhai delete to kia

@techsurge it has asked for the maximum distance, if they meet at the center only then there will be no distance only.. may be i am not getting the point u r tryin to explain!!
