English has become the common medium of communication by transcending borders across nations, races and castes.
Let's explore the depth of this dynamic language
A man observes the top of a tower at some angle 'A'. After walking a distance 100m the angle becomes '2A'.After a further distance of 75m the angle becomes '3A' then find sinA
Please discuss this question in the next class Thanks
The Zeroes of f[x^(1/9)]=x^2-3x-4 are (a) 4 and -1 (b) 4 and 1 (c)4^(1/9) and 1 (d)4^(1/9) and -1 Please solve the above question and discuss in the next wiziq.com session
In a music school 28 learn trumpet,30learn violin and 32 learn guitar. 6learn trumpet and violin, 8 learn violin and guitar,10 learn guitar and trumpet. The number of learners who learn only one instrument is 54. Also 20 students learn only violin. Every student learns at least one instrumentThen the number of students inthis school is:- (a)80 (b)75(c)70 (d) 65
Please discuss this question in the next class. Thanks
Here's a question: If x+y+z=0 and x^2+y^2+z^2=1 Then x^4+y^4+z^4 is equal to (a) 1/2 (b) 1/4 (c) 1 (d) 2 (e) none of these Please find time in your next CAT class and show me the solution of the above question Thanks
A and B are two points on the same level as Q the foot of the vertical tower PQ. The angles of the elevation of P from A and B are alpha and beta.Also Base angles triangle QBA are given and AB=c. Find the height of PQ
A ladder makes an angle alpha with the ground. The lower end is taken a distance 'a' away from the vertical wall and it causes a drop of 'b' to the other end of the ladder.The ladder now makes an angle beta with the ground.Show that a/b =tan [(alpha+beta)/2] Please sole these question in your next class. Thanks
