Let PQRS be a quadrilateral. If M and N are themid points of the sides PO and RS respectivelythen prove that PS+QR=2MN. |
|
Answer» Answer: Let \OVERLINE{m}, \overline{n}, \overline{p}, \overline{Q}, \overline{r} m , n , p , q , r and \overline{s} s be position vectors of M,N,P,Q,RM,N,P,Q,R and SS respectively. MM and NN are midpoints of PQPQ and RSRS \therefore \overline {m} = \dfrac {\overline {p} + \overline {q}}{2}∴ m = 2 p + q
and \overline {n} = \dfrac {\overline {r} + \overline {s}}{2} n = 2 r + s
\overline {PS} + \overline {QR} = \overline {s} - \overline {p} + \overline {r} - \overline {q} PS + QR = s − p + r − q
= (\overline {r} + \overline {s}) - (\overline {p} + \overline {q})=( r + s )−( p + q ) = 2\overline {n} - 2\overline {m}=2 n −2 m
= 2(\overline {n} - \overline {m})=2( n − m ) = 2\overline {MN}=2 MN Step-by-step explanation: |

|
Answer» Answer: Answers are given below w.r.t the position of the questions. Step-by-step explanation: Question 1 : For domain, f(x) must be a positive real number( including 0 ), which means √( 2 - 2x - x^2 ) ≥ 0 = > 2 - 2x - x^2 ≥ 0 = > x^2 + 2x - 2 ≤ 0 = > x^2 + 2x + 1 - 1 - 2 ≤ 0 = > ( x + 1 )^2 - 3 ≤ 0 = > ( x + 1 )^2 ≤ 3 = > - √3 ≤ x + 1 ≤ √3 = > - √3 - 1 ≤ x ≤ √3 - 1 Domain of this function is [ - √3 - 1 , √3 - 1 ]. LET, √( 2 - 2x - x^2 ) = a = > a^2 = 2 - 2x - x^2 = > x^2 + 2x - 2 + a^2 = 0 = > x^2 + 2x - ( 2 - a^2 ) = 0 Since a will always be a positive real number, discriminant of this quadratic equation will always be greater than 0 or 0. It means : = > 2^2 + 4( 1 )( 2 - a^2 ) ≥ 0 = > 4 + 4( 2 - a^2 ) ≥ 0 = > 1 + 2 - a^2 ≥ 0 = > 3 - a^2 ≥ 0 = > - a^2 ≥ - 3 = > a^2 ≤ 3 = > - √3 ≤ a ≤ √3 Since a can never be NEGATIVE { a = a real number under square root } = > 0 ≤ a ≤ √3 Range of the given function is [ 0 , √3 ]. Question 2 : i) For domain, f(x) must be a real number, here, x - l x l will always be a real number. Thus domain is { R }. For range, For every real number, l x l ≥ x = > l x l - x ≥ 0 = > x - l x l ≤ 0 Range is ( - ∞ , 0 ] ii) f(x) will always be a real number, so domain is { R }. For range, If x = +ve, l x l + x ≥ 0 { +ve no. + +ve no. = another +ve no. or 0 } If x = - ve, l x l + x = 0 { - x + x = 0 } Thus, l x l + x ≥ 0 l x l + x will always be a positive number. Hence, range is [ 0 , ∞ ).
Question 3 i) For domain, f(x) must be a real number. = > 1 / √( x - l x l ) must be real number. = > x - l x l > 0 = > x > l x l But for any real number l x l ≥ x Thus, domain = ∅, function is not defined. Thus, defining range is also not possible. ii) For domain, f(x) must be a real number. = > 1 / √( x + l x l ) must be real number. = > x + l x l > 0 { this says x > 0 } Thus, Domain is ( 0 , ∞ ). For range, = > 1 / √( x + x ) = a real number { l x l = x, since x ≠ 0 or any negative number } = > 1 / √(2x) = a = > a real number = a Thus, range of this function is ( 0 , ∞ ). |

|
Answer» Answer: x and Z can finish the work in 5 days Step-by-step EXPLANATION: =)(x+y+z)'s 1 day work=1/4 =)z's 1 day work=(x+y+z)'s 1 day work - (x+y)'s 1 day work =(1/4)-(1/5) =(5-4)/20 [By TAKING L.C.M] =1/20 =)x's 1 day work=(x+y+z)'s 1 day work-(y+z)'s 1 day work =(1/4)-(1/10) =(5-2)/20 [By taking L.C.M] =3/20 =)(x+z)'s 1 day work=(3/20)+(1/20) =4/20 =1/5 [By dividing both DENOMINATOR and numerator by 4] =)So,(x+z) can finish the work together in 5 days. |
