Solve the following inequalitiesQuestions a)solve inequality question aSolutionWe first arrange the zeros of the numerator and the denominator, of the rational expression on the left of the inequality symbol, on the number line, from smallest to the largest as follows.-∞ - 1 2 +∞Select a value of x in any of the intervals and use it to find the sign of the rational expression. Example for x = -3 in the interval (-∞ , -1), the rational expression (x - 2)/(x + 1) = (- 3 - 2)/(- 3 + 1) = 5 / 2. Hence the rational expression (x - 2)/(x + 1) is positive on the interval (-∞ , -1) . -∞ + - 1 2 +∞The zeros -1 and 2 are of odd multiplicity and therefore the sign of the expression (x - 2)/(x + 1) will change at both zeros as we go from on interval to another. Hence the signs of the expression (x - 2)/(x + 1) as we go from left to right are-∞ + - 1 - 2 + +∞The solution set of the inequality is given by the union of all intervals where (x - 2)/(x + 1) is positive or equal to 0. Hence the solution set for the above inequality, in interval notation, is given by:(-∞ , -1) ∪ [ 2 , +∞)Questions b)solve inequality question b |

ΔH R =∑ΔH f
(product) −∑ΔH f
(reactant)
∴ΔH R =(2×(−268.6))−(23+(−241.8)) ⇒ΔH R =−756kJ/mol Hence the standard ENTHALPY change will be −756kJ/mol Now, as we know that, ΔH=ΔU+Δn g RT ⇒ΔU=ΔH−Δn g RT Now from the given reaction, Δn g =N P −n R =(2+1)−(1+1)=1 T=300K(Given) R=8.314×10 −3 J/mol−K ∴ΔU=(−756)−(1×8.314×10 −3 ×300) ⇒ΔU=−756−2.494=−753.506kJ/mol Hence the standard internal ENERGY change will be −753.506kJ/mol.

Find the common factors of: (i) 15 and 25 35 and 50 (iii) 20 and 28 |
|
Answer» Step-by-step explanation: (i) 15 and 25We know that 1 × 15 = 15 3 × 5 = 15 Factors of 15 are 1, 3, 5 and 15.We know that 1 × 25 = 25 5 × 5 = 25 Factors of 25 are 1, 5 and 25. Therefore, the common factors are 1 and 5. (ii) 35 and 50We know that 1 × 35 = 35 5 × 7 = 35 Factors of 35 are 1, 5, 7, and 35.We know that 1 × 50 = 50 2 × 25 = 50 5 × 10 = 50 Factors of 50 are 1, 2, 5, 10, 25 and 50.Therefore, the common factors are 1 and 5.(iii)20 and 28We know that 1 × 20 = 20 2 × 10 = 20 4 × 5 = 20 Factors of 20 are 1, 2, 4, 5, 10 and 20. We know that 1 × 28 = 28 2 × 14 = 28 7 × 4 = 28 Factors of 28 are 1, 2, 4, 7, 14 and 28.Therefore, the common factors are 1, 2 and 4. |

All the species use the food AVAILABLE in the pond without competing with each other thus enhancing the survival of different species within the same area. Composite fish culture is the process of rearing different species of fish in the same area or fish pond. All the species use the food available in the pond without competing with each other thus enhancing the survival of different species within the same area.An ADVANTAGE of composite fish culture is that it increases the yield of fish. Nearly, five or six different species are grown together in a SINGLE fish pond. The survival rate of fish increases and their yield also increases without affecting the other species.

Solve for x and y y/2+x=4 2y+x/3=5 |
|
Answer» Step-by-step explanation: The given pair of EQUATIONS are: x + y/2 = 4 …………(i) 2y + x/3 = 5…………(ii) From (i) we GET, x + y/2 = 4 ⇒ 2x + y = 8 [After taking LCM] ⇒ y = 8 – 2x …..(iv) From (ii) we get, x + 6y = 15 …………(iii) [After taking LCM] Substituting y in (iii), we get x + 6(8 – 2x) = 15 ⇒ x + 48 – 12x = 15 ⇒ -11x = 15 – 48 ⇒ -11x = -33 ⇒ x = 3 PUTTING x = 3 in (iv), we get y = 8 – (2 x 3) ∴ y = 8 – 6 = 2 Hence, the solution of the given system of equation are x = 3 and y = 2 |
