Range of f(x) = 1 - | x - 2 | |
|
Answer» Answer: range is integers. Step-by-step explanation: f(x)=1-|x-2| now, |x-2| => x-2 or -(x-2) let ..... => f(x) = 1 - (x-2) f(x) = 1 - x + 2 = -x +3 f(1) = -1 + 3 = 2 ........ => f(x) = 1 - (- (x-2)) f(x) = 1 + x -2 = x -1 f(1) = 1-1 = 0 ......... if range R is natural numbers then, range R is whole numbers. if range R is whole numbers then, range R is integers. |

A positive integer whose sum is -5 |
|
Answer» Answer: Positive integer = 6 Negative Integer = -11 Step-by-step explanation: Positive INTEGERS : The positive integers are the numbers 1, 2, 3, ... sometimes called the counting numbers or natural numbers, denoted +Z . They are the solution to the simple linear RECURRENCE equation. Negative Integers : The negative integers are the numbers -1, -2, -3, ... sometimes called the counting numbers or natural numbers, denoted -Z . They are the solution to the simple linear recurrence equation. Now, We need to find a negative and positive integer such that their sum is -5 Let positive integer be X and negative integer be y Take x = 6 ⇒ 6 + y = -5 ⇒ y = -5 - 6 ⇒ y = -11 So, Positive integer = 6 Negative Integer = -11 |

Sin2a+sin2b+sin2c=4cosacosbcosc |
|
Answer» Answer: SIN(2A) + sin(2B) - sin(2C) = 2SIN(A + B)*cos(A - B) - 2*sin(C)*cos(C) WKT for a TRIANGLE A + B + C = 180°, A + B = 180° - C ==> sin(A + B) = sin(180° - C) = sin(C) Also cos(C) = cos{180° - (A + B)} = -cos(A + B) Thus , sin(2A) + sin(2B) - sin(2C) = 2sin(C)*cos(A - B) - 2*sin(C)*cos(C) = 2sin(C){cos(A - B) - cos(C)} = 2sin(C){cos(A - B) + cos(A + B)} = 2sin(C)*2cos(A)*cos(B) [Identity] = 4*cos(A)*cos(B)*sin(C) Thus sin(2A) + sin(2B) - sin(2C) = 4*cos(A)*cos(B)*sin(C) |

If x=root 2+1 ,find the value of x+1/x |
|
Answer» GIVEN :- To find :- Solution :- Rationalise the denominator The rationalising FACTOR of √2 + 1 is √2 - 1. So multiply both numerator and denominator with rationalising factor [SINCE (x + y)(x - y) = x² - y² and here x = √2 and y = 1] So we got value of 1/x as √2 - 1 Now we know values as So now we can find x + 1/x |

Answer» Answer: Step-by-step EXPLANATION: sin(B+C-A)=COS(C+A-B)=tan(A+B-C)=1 Since sin(B+C-A)=1 hence B+C-A=90⁰,……(i) cos(C+A-B)=0 hence C+A-B=0⁰……….(ii) tan(A+B-C)=1 hence A+B-C=45⁰………..(iii) Adding (i)and(ii)GIVES 2C=90⁰ hence C =45⁰ Adding (ii) and ( iii) gives 2A= 45⁰ hence A=22.5⁰ From (i) B=90⁰+A-C=90⁰+22.5⁰–45⁰=67.5⁰ |
