If a²+b²=13 and ab=6, find : 1. a+b 2. a-b |
|
Answer» Answer: 3(a+B) 2 −2(a−b) 2
We know, (a+b) 2 =a 2 +b 2 +2ab =13+2(6) =13+12 =25 =>(a+b)=± 25
=>(a+b)=±5 Again, (a−b) 2 =a 2 +b 2 −2ab =13−2(6) =13−12 =1 =>(a−b)=±1 Putting the VALUES, we get, 3(±5) 2 −2(±1) 2
=75−2 =73 |

Classify all the following numbers as natural, whole. Integer rational, or irrational List all that apply. b. 0 |
|
Answer» Answer: Natural numbers are the numbers 1 , 2 , 3 , ... or the numbers 0 , 1 , 2 , 3 , ... according to whose definition you CHOOSE. So 0 may be considered a natural number or not. Whole numbers are the numbers 0 , 1 , 2 , 3 , ... Integers INCLUDE negative numbers, but not fractions. So the integers are: 0 , 1 , − 1 , 2 , − 2 , 3 , − 3 , ... Rational numbers are any number that can be expressed as p q where p and q are integers and q ≠ 0 . So , 12.42 , − 17 3 and 0 are rational numbers. There are infinitely many rational numbers, but they do not form a continuous line. The continuous line of numbers is called the real number line. It includes all the previous numbers we have mentioned, but also numbers LIKE √ 2 , π and e , which are not rational. Some real numbers - such as √ 2 - are the roots of polynomials with integer coefficients. These are known as algebraic numbers. Irrational numbers are any real numbers that are not rational. So 0 is not an irrational number |

the sum of ages of mother and her daughter is 66 years. After 12 years ratio of ages will be 2: 1. Find mothers present age. |
|
Answer» Step-by-step explanation: let's SOLVE this one, LET's the present age of mother and DAUGHTER be x and y, Now , according to question x+y=66 x=66-y.................1) after 12 YEARS, their ratio will be 2:1 so, (x+12)/(y+12) = 2/1 x+12=2(y+12) x+12=2y+24 x-2y=12.............2) Now, putting the value of x here, we get 66-y-2y=12 66-12=3y 54=3y y=18 again putting the value of y in 1st equations, x=66-18 x=48 therefore present age of mother is 48 years and daughter is 18 years.. if you like this process and ANSWER mark it as brainliest if you don't that's up to you... thanks!! |

Thomas bought 2 tables and 8 chairs for Rs.6000. At the same rate, Mohan bought 3 tables and 10chairs for Rs.8000. Calculate the cost of one table. Calculate the cost of one chair.? |
|
Answer» Answer: Cost of one table is RS. 1000 and cost of one chair is Rs. 500 Step-by-step explanation: Let cost of one table be X and cost of one chair be y For Thomas Cost of 2 tables + Cost of 8 Chairs = 6000 2x + 8Y = 6000 ---(i) For Mohan Cost of 3 tables + Cost of 10 Chairs = 8000 3x + 10y = 8000 ---- (ii) Multiplying (i) with 3 and (ii) with 2 we get 6x + 24y = 18000 ---(iii) 6x + 20y = 16000 --- (iv) Subtracting (iv) from (iii) (6x + 24y) - (6x + 20y) = 18000 - 16000 6x + 24y - 6x - 20y = 2000 4y = 2000 y = 500 Putting value of y in (i) 2x + 8(500) = 6000 2x + 4000 = 6000 2x = 6000 - 4000 2x = 2000 x = 1000 Hence, the cost of one table is Rs. 1000 and the cost of one chair is Rs. 500. |
