I already gave you the solution of this particular question, Try to get the concept from the hint i am posting....click
see as AD is internal bisector o angle BAC , it ( that is the point D ) will divide BD and DC in the ratio of AB/AC i.e 1:3 . now using the division formula get the cordinate of D . and find the...
First reduce the eqn from double log to a single log eqn. Follow the steps: Remove the logbase3/4 using the exponential equivalent. This would give an eqn of 2 terms equated to a number raised to the...
Hi Student Real Part of Above Complex Number is x= 4ab Imaginary Part of Above Complex Number is y=-2(a 2 -b 2 ) Such that z= x+ iy Now Calculating Square root of Complex Number = = ± ( where...
Be the first one to answer
If, each digit of 4 digit number is increased by 1, then the new number is increased by 1111 than the original number. For eg. consider 1234. If each digit is increased by 1, then new number is 2345....
Let the sides of triangle be a, b, c so that b + c > a Take a = 20. Since a, b, c are distinct - If b = 19, c can take values from 2 to 18 = 17 distinct no. of values if b = 18, c can take values from...
Hii shah as you know 1 + w +w ² = 0 whem w is cube root of unity.hence you can write it as -w -w² = 1 therefore 2^5 is 32.. . . . . . . . ….. . . . .
As we know 1 +w +w² = 0 so, 1 = -w -w² So , (1+1)^5=32
Hi Student a= first term l=last term S1= n/2(a+l) S2=2n/2(a+l)= n(a+l) S3= 3n/2(a+l) = n(a+l) + n/2(a+l) =S1+ S2 Clearly option A satisfies this....
how to proff?
Of course we can have alternative ways to do it and I have given the answer which is one of them ….... Good luck for your exams!!!!!!!!!...
Hi student It is a necessary condition when roots are of opposite sign The solution from above condition might ne covered in some other condition from the source from which you have read,...
A
thnk u
from four points how only one straight can be formed
units of 7 754 =7 377 *7 2 therefore 7 2 =49 and the units digit of it is 9
Two events are independent if the occurence of one event does not effect the probability of other. Lets say 1 st event to be A and 2 nd to be B. Let C to be intersection of A and B. A and B are...
You will get infinite number of ordered pairs for this equation. 10y + 10 x = xy –1 y = – (1 + 10x)/(10 – x) & x = – (1 + 10y)/(10 – y) This is not defined for x = 10 & y = 10
