Distance between (x,1)and (-2,3) is 2√2 then x= |
|
Answer»
Distance = √( x2 -x1)²+( y2-y1)² Here points are(X, -1)and (-2,3) Distance between the points on=2√2. Here x1=x, x2=-2,y1=1,y2=3 2√2 = √(-2-x)²+ (3-1)² Squaring on both SIDES..... (2√2)²= [√(-2-x) ²+(3-1)²] ² 8 = (-2-x)² +(3-1)² 8 = [(2)²+x²-2×(2)(x) +(3)²+1²-2×(3)(1)] [SINCE (a-b) ²= a²+b²-2ab] 8 = 4+x²- 4x+9 +1-6 8 = x² -4x+8 X² -4x = 0 X(x-4) = 0 X-4 = 0/x :.

For any positive integer n prove that n cube - n is divisible by 6 |
|
Answer» Step-by-step explanation: N3 - n = n (n2 - 1) = n (n - 1) (n + 1) Whenever a number is divided by 3, the REMAINDER obtained is either 0 or 1 or 2. ∴ n = 3p or 3p + 1 or 3p + 2, where p is some integer. If n = 3p, then n is divisible by 3. If n = 3p + 1, then n – 1 = 3p + 1 –1 = 3p is divisible by 3. If n = 3p + 2, then n + 1 = 3p + 2 + 1 = 3p + 3 = 3(p + 1) is divisible by 3. So, we can say that one of the numbers among n, n – 1 and n + 1 is always divisible by 3. ⇒ n (n – 1) (n + 1) is divisible by 3.
Similarly, whenever a number is divided 2, the remainder obtained is 0 or 1. ∴ n = 2Q or 2q + 1, where Q is some integer. If n = 2q, then n is divisible by 2. If n = 2q + 1, then n – 1 = 2q + 1 – 1 = 2q is divisible by 2 and n + 1 = 2q + 1 + 1 = 2q + 2 = 2 (q + 1) is divisible by 2. So, we can say that one of the numbers among n, n – 1 and n + 1 is always divisible by 2. ⇒ n (n – 1) (n + 1) is divisible by 2. Since, n (n – 1) (n + 1) is divisible by 2 and 3. ∴ n (n-1) (n+1) = n3 - n is divisible by 6.( If a number is divisible by both 2 and 3 , then it is divisible by 6) |

Divide rs 50760 into two parts such that if one part is invested in 9%, rs 100 shares at 8% dis and the other in 8%, 100 shares at 8% premium, the annual incomes from both the investment are equal |
|
Answer» GIVEN : The Invested amount (in two parts) = ₹ 50,760 Face VALUE of first part = ₹100 Dividend = 9% Discount = 8% Face value of second part = ₹100 Dividend = 8% PREMIUM = 8% To FIND : The amount of both the investment. Solution : Let we divide the amount in two parts. First part be 'x' so the other part = (50760-x) The first part of shares bought with Rs. x at the discount of 8%. Market value of one share of first part = 100 - (8% of 100) = 100 - 8 = ₹92 Number of shares = = INCOME from first part = No. of shares × dividend × face value = = Second part of shares bought with Rs. 50760-x at the premium of 8%. Market value of one share of second part = 100 +(8% of 100) = 100 + 8 = Rs. 108 Number of shares = Income from second part of investment = = According to question income from both parts are equal.
x = 21873.16 First part of investment = 21873.16 so the other part of investment = 50760 - 21873.16 = 28886.84 First part of investment is 21873.16 and the other part is 28886.84. |
