||x-2|-1|>= 3find the value of x |
Answer» GIVEN EQUATION: ||x - 2| - 1| ≥ 3Find that exactly at which value is the result equal to 3, since the numbers are being subtracted, see the PATTERN of RESULTS from keeping value of x as 2 to (-2). At x = -2, the result is 3. And before that, all the results are less than 3. Thus, for all values less than -2, the result will be GREATER than 3. Keep x = -2 Result = 3 Since 3 = 3, x = -2 So, x € [-2, -infinity] |

The rectangle can be formed by swapping any pair of columns of given matrix. Example: Input: bool mat[][] = { {0, 1, 0, 1, 0}, {0, 1, 0, 1, 1}, {1, 1, 0, 1, 0} }; Output: 6 The largest rectangle's area is 6. The rectangle can be formed by swapping column 2 with 3 The matrix after swapping will be 0 0 1 1 0 0 0 1 1 1 1 0 1 1 0 Input: bool mat[R][C] = { {0, 1, 0, 1, 0}, {0, 1, 1, 1, 1}, {1, 1, 1, 0, 1}, {1, 1, 1, 1, 1} }; Output: 9 Recommended: Please solve it on “PRACTICE” first, before moving on to the solution. The idea is to use an AUXILIARY matrix to store count of consecutive 1’s in EVERY column. Once we have these counts, we sort all rows of auxiliary matrix in non-increasing order of counts. Finally traverse the sorted rows to find the maximum area. Note : After forming the auxiliary matrix each row becomes independent, hence we can swap or sort each row independently.It is because we can only swap columns, so we have made each row independent and find the max area of rectangle possible with row and column. Below are detailed STEPS for first example mentioned above. Step 1: First of all, calculate no. of consecutive 1’s in every column. An auxiliary array hist[][] is used to store the counts of consecutive 1’s. So for the above first example, contents of hist[R][C] would be 0 1 0 1 0 0 2 0 2 1 1 3 0 3 0 Time complexity of this step is O(R*C) Step 2: Sort the columns in non-increasing fashion. After sorting step the matrix hist[][] would be 1 1 0 0 0 2 2 1 0 0 3 3 1 0 0 This step can be done in O(R * (R + C)). Since we know that the values are in range from 0 to R, we can use counting sort for every row. The sorting is actually the swapping of columns. If we look at the 3rd row under step 2: 3 3 1 0 0 The sorted row CORRESPONDS to swapping the columns so that the column with the highest possible rectangle is placed first, after that comes the column that allows the second highest rectangle and so on. So, in the example there are 2 columns that can form a rectangle of height 3. That makes an area of 3*2=6. If we try to make the rectangle wider the height drops to 1, because there are no columns left that allow a higher rectangle on the 3rd row. Step 3: Traverse each row of hist[][] and check for the max area. Since every row is sorted by count of 1’s, current area can be calculated by multiplying column number with value in hist[i][j]. This step also takes O(R * C) time. |

A father says to his son, "7 years ago, I was 7 times as old as you were and after 3 years ,I will be 3 times as old as you will be". Find their present ages. |
|
Answer» Answer: 42 years and 12 years Step-by-step explanation: Let father's present age = x years and SON's present age = y years According to the first condition:x − 7 = 7 (y − 7)⇒ x − 7 = 7y − 49⇒ x − 7y = −49 + 7⇒ x − 7y = −42 ...........(1) According to the second condition:x + 3 = 3 (y + 3)⇒ x + 3 = 3Y + 9⇒ x − 3y = 9 − 3⇒ x − 3y = 6 ...........(2) Subtracting (1) from (2) we get, 4y = 48⇒ y = 48/4 = 12 Putting the VALUE of y in (1) we get,x − 7 × 12 = −42⇒ x − 84 = −42⇒ x = −42 + 84⇒ x = 42 Hence father's age is 42 years and son's present age is 12 years.

How many Triangles can make in 24 centimetre square |
|
Answer» Answer: Let a=8 cm , b =6 cm and ANGLE between sides a and b is C. Area of triangle ABC = 1/2.a.b.sinC. 1/2.8 cm.6 cm.sinC = 12 cm^2 24 cm^2.sinC=12 cm^2 sinC= 12cm^2/24 cm^2= 1/2 C= 30° ,150° are only possible (as sum of all interior angles is 180°). Thus, only two TRIANGLES are possible in which in 1st triangle angle between given sides is 30° and in 2nd triangle angle between sides is 150°. , Answer. Second method:- Let third side is x cm long. a= 8 cm , b = 6 cm and c = x cm. s=(a+b+c)/2=(8+6+x)/2= 7+(x/2). Area of triangle =[s (s-a) (s-b) (s-c)]^1/2 12 =[{7+(x/2)}.{x/2–1}.{x/2+1}.{7-x/2}]^1/2 12 =[{49-x^2/4}.{x^2/4–1}]^1/2 On squaring both sides 144 =49x^2/4–49-x^4/16+x^/4 193 =50x^2/4-x^4/16 x^4/16–50x^2/4+193 =0 (x^2/4)^2–2×(x^2/4)×25+(25)^2–625+193=0 (x^2/4 -25)^2= 432. (x^2/4-25)= +/-12.(3^1/2) = +/-20.784 x^2/4 = 25 +/-20.784 x^2/4= 45.784 , 4.216 x^2= 183.136 , 16.864 x= 13.53 cm , 4.11 cm.

Can two number have the following HCF and LCMi)HCF=20 AND LCM =535ii)HCF=15 AND LCM =525 |
|
Answer» Step-by-step EXPLANATION: Given that: can TWO number have the following HCF and LCM i)HCF=20 AND LCM =535 ii)HCF=15 AND LCM =525. To find: Is true or not? Solution: First of all one should know that LCM and HCF of two given numbers are like that HCF is a factor of LCM. or in other words LCM is a multiple of HCF. on conclusion one can say that HCF divides LCM completely. i)HCF=20 AND LCM =535 Ans: 20)535(26 40 --------- 120 ------- 15 ------- Not true.Not possible, because LCM is not completely divisible by HCF. ii)HCF=15 AND LCM =525. Sol:15)525(35 45 --------- 75 75 ------- 0 ------- TrueYes,it is possible. Because LCM us completely divisible by HCF. Hope it helps you. |
