20.	Find the fraction such that,if its numerator is diminished by unity,it reduces to 1/2and becomes equal to 2 when the numerator is increased by 5 and the denominator is diminished by 6.
Answer» Let the FRACTION be x/y. Here, x-1/y = 1/2 or, 2x - 2 = y x+5/y-6 = 2 or, x + 5 = 2Y -12 Thus, x + 5 = 2(2x - 2) - 12 or, x + 5 = 4X - 16 3x = 21 x = 7 and y = 14 - 2 = 12 Thus, the fraction is 7/12.

Discussion

24.	Express the first quantity as a percent of the second quantity
Answer» Assume the 1st QUANTITY is 120, and the 2nd quantity is 240. So FIRST, we have to FORM a fraction with them = 120/240. Then we MULTIPLY the fraction with 100 = 120/240 x 100= 50. This means that 120 is 50% of 240. Let us try another one. Assume the 1st quantity is 73, and the SECOND quantity is 365. We form a fraction = 73/365. We multiply it by 100 = 73/365 x 100= 20%. Hence, 73 is 20% of 365. Now, one more... Assume the 1st quantity to be 500, and the 2nd quantity to be 10,000. So let us form a fraction = 500/10000. We multiply by 100 = 500/10000 x 100 = 5. Thus, 500 is 5% of 10,000.

Discussion

32.	Prove that:(its urgent plz help someone who's intelligent enough !!)
Answer» LET x = TAN A , y = Tan B , z = Tan C (x - y)/(1+x y) = tan (A-B) (y-z)//(1+y z) = tan (B-C) (z-x)/(1+z x) = tan (C - A) LHS = (A-B) + (B-C) + (C-A) = 0 RHS is also similar to LHS. If we assume x³ = tan P , y³ = tan Q , z³ = tan R RHS = tan⁻¹ (tan (P-Q) ) + tan⁻¹ [tan (Q-R) ] + tan⁻¹ [ tan (R-P) ] = 0 LHS = RHS

33.	If the HCF of x²+x-12 and 2x² -kx-9 is x-k , find the value of 'k'.
Answer» HCF of x²+x-12 and 2x² -kx-9 is x-k so (x-k) is a FACTOR of both the polynomials. So x=k is a zero of both the polynomials. So F(k)=0 in both cases. thus k² + k - 12 = 0 --------------(1) 2k² - k² - 9 = 0 --------------(2) from EQUATION 1, k = 3,-4 from equation 2, k = +3, -3 +3 is common to both the SOLUTIONS. So value of k is 3.

39.	The students in a school are having a cup stacking contest. John has a pyramid 9 layers high. How many cups will he need to add to his pyramid to increase the number of layers to 12?
Answer» Please see the DOCUMENT enclosed. If the stacking is done as per that method, then we need, for a stack of L LEVELS, total number of CUPS at level L = L total number of cups for all levels from 1 to L : 1 + 2 + 3 + ... + L = L ( L + 1)/2 So the number of cups needed to increase the number of LAYERS to 12 from 9 is: 12(12+1)/2 - 9 (9+1)/2 = 78 - 45 = 33 ==================== Another method is: We need L more cups to increase the number of layers from L - 1 to L. Hence, we need, to go from level 9 to level 12: 10+11+12 = 33 cups more.

Answer» I dont know the BEST way of solving this. I am able to solve it in the following manner. y - x y' = x + y y' (x + y) y' = y - x --- equation (1) Let y = g x => y' = g + x g' Substitute in equation (1), x g + x² g' + x g² + x² g g' = g x - x x g' (1 + g) = - (g² + 1) - 1/x = (g + 1) g' / (g² + 1) -1/ x = g g' / (g² + 1) + g' / (g² + 1) Integrating we get, LN 1/x + Ln K = 1/2 Ln (1 + g²) + tan⁻¹ g Substitute g = y/x, and simplify. $Ln\ \frac{K}{x\sqrt{1+g^2}} = tan^{-1}g\\\\Ln\ \frac{Kx}{x^2+y^2}=tan^{-1}\frac{y}{x}\\\\Or,\ x^2+y^2=K_1\ e^{-2\ tan^{-1}\frac{y}{x}}\\$ You may verify the SOLUTION, by DIFFERENTIATING this equation and OBTAINING the expression for y'.

(1) ........ x1 = -1-x2 Sub in (2) ........ -1-x2 + x3 = 14........(7) Now subtracting (7) and (3) we get, 2x3 = 22 x3 = 11 Sub x3 in (2) ........x1+11 = 14 x1 = 3 and so x2 = -4 now let us find y terms. (3) ............y1 = 5 - y2 sub in (5).........5-y2+y3 = 6.........(8) Now subtracting (8) and (6) we get, y3 = 4 now sub y3 in (5)...... y1 = 2 and so y2 = 3 now the vertices are (3,2) (-4,3) (11,4) Area of the triangle = (3(3-4) + (-4) (4-2) + 11(2-3))/2 = (-3 -8 -11)2 = - 11 Remove the negative SIGN (-) from the number -11. The area of the triangle is 11 sq.units. Because the formula calls for absolute value, you SIMPLY remove the negative sign.
