13. Without doing the actual addition, find the sumof :(i) 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19+ 21 + 23(ii) 1 + 3 + 5 + 7 + 9 + ................ +39 + 41(iii) 1 + 3 + 5+ 7 + 9 + ......... +51 + 53 |
|
Answer» i) 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 Using Arithmetic Progression First term (a) = 1 Common difference (d) = 3 - 1 = 2 Last term (l) = 23 Number of terms (n) = 12 We have to find the summative (sum) of the GIVEN A.P. Sn = n/2 (a + l) → 12/2 (1 + 23) → 6 (24) → 144 ii) 1 + 3 + 5 + 7 + 9 + ................ +39 + 41 First term (a) = 1 Common difference = 3 - 1 = 2 Last term (an or l) = 41 an = a + (n - 1)d OR l = a + (n - 1)d 41 = 1 + (n - 1)2 40 = (n - 1)2 20 = n - 1 n = 21 Sn = n/2 (a + l) → 21/2 (1 + 41) → 21/2 (42) → 21(21) → 441 iii) 1 + 3 + 5+ 7 + 9 + ......... +51 + 53 First term (a) = 1 Common difference = 3 - 1 = 2 Last term (an or l) = 53 an = a + (n - 1)d OR l = a + (n - 1)d 53 = 1 + (n - 1)2 52 = (n - 1)2 26 = n - 1 27 = n Sn = n/2 (a + l) → 27/2 (1 + 53) → 27/2 (54) → 27(27) → 729 |

(iv) A Finite set, As, the number of PEOPLE from village are countable, ALTHOUGH being a large number. (v) A Finite set, The total number of Apparatuses are countable. (vi) W = {0, 1, 2, 3, 4, 5,...} [An Infinite set, ∵ n(W)=∞] (vii) Q is an infinite set. As, there exists infinite number of rational numbers including all the integers(infinite), & x is of the form "p/q", q≠0, So, there can be made many such combinations of rational numbers. |

Answer» Answer: There are eight euro coin denominations, ranging from one cent to two euros[1] (the euro is divided into a hundred cents). The COINS first came into use in 2002. They have a common reverse, portraying a map of Europe, but each country in the eurozone has its own DESIGN on the obverse, which means that each coin has a variety of different designs in circulation at once. Four European microstates which use the euro as their currency also have the right to mint coins with their own designs on the obverse side.There are eight euro coin denominations, ranging from one cent to two euros[1] (the euro is divided into a hundred cents).

Using tan (a+b)=tana+tanb/1-tana tanb p.t tan75=(2+root3) |
|
Answer» Answer: Step-by-step explanation: From the properties of TRIGONOMETRIC RATIOS : tan45° = 1 ; tan30° = 1 / √3
Given, tan( a + b ) = ( TANA + tanb ) / ( 1 - tana.tanb ) Here, ⇒ tan75° ⇒ tan( 45° + 30° ) ⇒ ( tan45° + tan30° ) / ( 1 - tan45°tan30° ) ⇒ { 1 + ( 1 / √3 ) } / { 1 - ( 1 * 1 / √3 ) } ⇒ { ( √3 + 1 ) / √3 } / { 1 - ( 1 / √3 ) } ⇒ { ( √3 + 1 ) / √3 } / { ( √3 - 1 ) / √3 } ⇒ ( √3 + 1 ) / ( √3 - 1 )
Multiply as well as DIVIDE by ( √3 + 1 ): ⇒ ( √3 + 1 )( √3 + 1 ) / ( √3 - 1 )( √3 + 1 ) ⇒ ( √3 + 1 )^2 / { ( √3 )^2 - ( 1 )^2 } ⇒ ( √3 + 1 )^2 / ( 3 - 1 ) ⇒ ( 3 + 1 + 2√3 ) / 2 ⇒ ( 4 + 2√3 ) / 2 ⇒ 2 + √3 Hence proved. |
