@ sandeep Kindly repost your query again , i am not getting what exactly u want to know about it > ?? if u have any specific ques related to class 8 th then u can ask here in the form of text as well ...
Let k 1/2 +1/k 1/2 = a squaring both sides we get, k + 1/k + 2 = a^2 k + 1/k = a^2 – 2 put k value, (8 + 60^(1/2)) + 1/(8+60^(1/2)) + 2 = a^2 (8 + 2root(15)) + 1/(8 + 2root(15)) + 2 = a^2 8 +...

See these marks are not of much important to your career but of course they teach you a lesson so that you analyze your mistake and try to improve.For 8 grade all you need to do is do mathematics...
Its very simple!Just equate the denominators of both the rational numbers and Find all the rational numbers between them by increasing numbers of numerator.That`s your answer
Let Let age of Anup is x yrs thus, Father's age= (100-x) Anuj's age = (100-x)/5 Eq. 1 (Translating 2nd last line#) (100-x)-x+(100-x)/5=x+8 600-11x=5x+40 16x=540 x =35 yrs age of Anup is 35 yrs age of ...
69+61-100 i.e. 30% is the answer to the question as these will be counted twice. HOPE IT Helps. ALL THE BEST. Thank You.
The edge length and the corresponding number of cubes required for it are given below 1cm – 1 2cm – 8 3cm – 27 4cm – 64 and so on. From this we get if ‘x’ is the number of cubes, then edge length = x ...
a) 1.345 correct to 3 significant figures=1.34 b) 0.132 correct to 1 significant figure=0.1 c) 0.056 correct to 1 significant figure=0.06 d) 12.37 correct to 4 significant figures=12.37
From identity remember, If x+y+z=0 then x^3 + y^3 + z^3 = 3xyz. In given function of x,y,z x^2 (y+z) +y^2 (z+x) + z^2 (x+y) = it becomes = -( x^3 + y^3 + z^3) = -3xyz which is the required answer.
let y = 24sin@ + 7cos@ ….................(1) differentiate it w.r.t @ and equate it 0. dy/d@ = 24cos@ + -7sin@ = 0 tan@ = 24/7 ==> sin@ = 24/25 ==> cos@ = 7/25 Now put sin@ and cos@ values in eqn....
Let the 2 digit number as 10b + a so here the digit at tens place is b and at units plac a it is given that a + b = 9..........................(eq 1) and 10b + a = 10a + b + 27 9b – 9a = 27 9( a - b...
cos(47)+cos(73) cos(30+17)+cos(90-17) cos(30+17)+sin17 according to ASTC rule cos(30).cos(17)-sin(30).sin(17)+sin(17) cos(30).cos(17)-0.5.sin(17)+sin(17) cos(30).cos(17)+0.5sin(17)...
Well thanks but I mentioned that I knew this method. Wanted to know if I can calculate it by changing the trigonometric function into single and then calculate.
Hii You can fin out the amounts at the end of second year and third year. Equate that to 98. With this formula you will get the value of principal
THE ANSWER OF YOUR QUESTION IS ‘0’(FOR THREE QUESTIONS)BECAUSE OF SIN180 IS ‘0’ SO TAN 180 AUTOMATICALLY ‘0’.THANK YOU.
Its like a function 16/x 2 +9x 2 . Consider this function and try to find out its minimum value . OR use AM >= Gm you will get the answer.
I am not clear with your approach. If possible pls explain it. Sides are given in AP then from where angles came to be 60 and 30? Thank you.
Cos 113 @.Sin 113 @ = (Cos@.Sin@) 113 (Cos@.Sin@) 113 = ((Sin2@)/2) 113 NOTE : Maximum value of Sin2@ is same as that of Sin@. That is, 1. Proof? Let 2@ be ANY other angle. (Say X) Maximum of Sin(Any ...
Sorry for the careless mistake. Let the total no. of voters be x. Out of these 0.9x will vote. Now only 80% of these are valid. which means valid votes are 0.72x Now wining candidate get 40% of total...
