Answer to first question: x=|a+bw+cw 2 | + |a+bw 2 +cw| x=|a| +x=|a| +|bw|+|cw 2 |+|a| +|bw 2 |+|cw| x=|a|+|b|×|w|+|c|×|w 2 |+|a| +|b|×|w 2 |+|c|×|w| x=|a|+|b|×1+|c|×1+|a| +|b|×1+|c|×1 (since |w|,...
do we need to factorise this or what?
Above expression becomes y= (4- x 2 ) 3 (2-x) Find dy/dx Then find values of x for which dy/dx becomes 0. Check on which value the greatest value appears.
0 {x} <1 so 0 2{x}< 2 which means -3 2{x} -3 <-1 But log is defined for positive base only So there will no value of x for which above is defined Domain – { }
I tried using bayes theorem but there is a little confusion.if u can plz tell me the value of P(E1) and P(E2) P(A/E1) and P(A/E2) it will be of great help. also tell which is the correct option. thank...
x^2*b^2+y^2*a^2-a^2*b*x = 0
a^2*y^2+b^2*x^2-a^2*b*x=0
3/4-(case 1:(1/2*1/3*1+1/2*2/3*3/4) + case 2:(1/2*2/5*2/3+1/2*3/5*2/3)) This has to be solved by taking cases.. Case 1 is drawing a white in first attempt and 2 is for drawing a black (it is one in...
Dear student, The image you gave is very light and opaque. Questions are not clear. Please post it one question at a time in a better quality. Thanks,
Be the first one to answer
Hello student, Let the given observations be x 1 , x 2 , …. x 20 . and x M be their mean. Given that n = 20 and variance is 5. So, If each observation is multiplied by 2, then the new...
Hello student, Let the required foot of perpendicular be P(x 1 , y 1 ). Let O be the point O(-1, 3) and AB be the line 3x – 4y – 16 = 0. Slope of AB = -3/-4 = ¾. Since OP is...
Hello student, First of all our aim shall be to find out the equation of the plane determined by the points A (3, –1, 2), B (5, 2, 4) and C (–1, –1, 6). The equation of the plane...
Z=a(1+i)
Hello student, Since we are required to find out the point in the xy-plane, hence the z-coordinate would be zero. Let the required point be P(x, y, 0). Then AP = BP = CP (Since it is equidistant from...
Hello student, Your question is not clear and seems to be incomplete. Please recheck your question and post it again.
Hii The method of differences is used when we are not given the sum of the series. For example, if we wanted to find the sum, ∑nr=1ur of some series where the terms follow some certain pattern....
Let two numbers be x and y AM = (a+b)/2 HM= (2ab)/(a+b) GM= (a+b)/2 = +15 (a+b)/2= 2ab/(a+b) + 27 Solving above you will get 120 and 30 as 2 numbers
Find your answer inthe image. I have shown way of doing, you have to do the calculations.

You can go for askIITians self study package of Permutation and Combination. That s the best way to prepare for IIT JEE
