Solution set of x(x^2+x+1)≤0 is |
|
Answer» Answer: Step-by-step explanation: Answered Mar 1, 2015 The question is x(x-1)(x+2)>0 Firt ignore the '>' sign: so: x(x-1)(x+2)=0 Since 3 numbers are multiplied to give 0, then each may potentially be zero, so: x = 0 x - 1 = 0, which means x = 1 x + 2 = 0, which means x = -2 So, you have 3 numbers -2, 0, 1 Now, draw a straight line and mark these 3 points on the line. You can see now that it these numbers have divided the line into 4 different regions. Region 1 is (-inf, -2) -- that is all numbers to the left of -2. Region 2 is (-2,0) --- that is all numbers between -2 and 0 Region 3 is (0,1) --- that is all numbers between 0,1 Region 4 is (1,inf)--- that is all numbers to the right of 1
Your strategy now, is to test a number inside of each of these 4 regions. Basically you pick a number inside, but not the end values. You substitute the number into the ORIGINAL inequality for x, and see which ones are true. Hence: Region 1: (-inf, -2), I can choose -5 since its in the region to the left of -2. I get: (-5)(-5-1)(-5+2) >? 0 I used '?' because I am not sure if it is true so: (-5)(-6)(-3) >? 0 Finally -90 >? 0 is false. SO Mark this region with an X on your line Region 2: (-2,0), I can choose -1 since its between -2 and 0. I get: (-1)(-1-1)(-1+2) >? 0 I used '?' because I am not sure if it is true so: (-1)(-2)(1) >? 0 Finally 2 >? 0 is True. SO Mark this region with an check mark on your line Region 3: (0,1), I can choose 0.5 since its between 0 and 1. I get: (0.5)(0.5-1)(0.5+2) >? 0 I used '?' because I am not sure if it is true so: (0.5)(-0.5)(2.5) >? 0 Finally -0.625>? 0 is false. SO Mark this region with an X on your line Finally: Region 4: (1,inf), I can choose 5 since its in the region to the right of 1. I get: (5)(5-1)(5+2) >? 0 I used '?' because I am not sure if it is true so: (5)(4)(7) >? 0 Finally 140 >? 0 is true. SO Mark this region with a check on your line Finally: We have 2 regions that were true (check marks) Regions 2 and 4: (-2,0) and (1,inf) We WRITE them together USING the U (for union) Final answer: (-2,0) U (1,inf) |

sum of two digits of a 2 digit number is 12. if the digits are reversed, the new number, so formed increase by 36. find the number |
|
Answer» Answer: Tens digit of NUMBER = x Ones digit of number = 12-x Original Number = 10x+12-x = 9x+12
REVERSED Number = 10(12-x)+x = 120-10x+x = 120-9x According to the question, 9x+12+36=120-9x 9x+48=120-9x 9x+9x=120-48 18x=72 x=72/18 x=4 Original Number = 9x+12 = 9(4)+12 = 36+12 = 48 is the number

What are two numbers whose sum is 58 and difference is 28? |
|
Answer» Step-by-step explanation: let the numbers be a and B Now, a+b = 58 --------1 a-b=28---------2 On subtracting EQ 2 from 1 we get, a+b=58 - a - b = 28 => 2b =30 b = 15 On substituting the value of b in eq 2. {you can SUBSTITUTE in any eq.} a-15=28 a=28+15 a=43 Thus, the REQUIRED numbers are 43 and 15 |

If the sum of two opposite angles of a parallelogram is 110° , find the measure of each of its angles. |
|
Answer» Step-by-step explanation: In a PARALLELOGRAM, it is known that OPPOSITE angles are equal. If the SUM is 110degrees, each angle should be 110/2=55 degrees.(you got 2 angles already0 also adjacent angles in a parallelogram are supplementary. So other angle will be 180-55=125 degrees. Using the same rule above, you get its opposite angle as the same. hence the required ANS is 125,125,55,55. to verify..SUMMATION should be 360 degrees. thank you |
