Find the coordinate of point which divide linesegment to (-2., 2)(2, 8) |
| Answer» Let P (x1, y1) Q(x2, y2) and R(x3, y3) be the points which divide the line segment AB into four equal parts.Then, P divides AB in the ratio 1 : 3 internally.{tex}x=\\frac{mx_2+nx_1}{m+n}{/tex}\xa0{tex}\\therefore x _ { 1 } = \\frac { ( 1 ) ( 2 ) + ( 3 ) ( - 2 ) } { 1 + 3 }{/tex}{tex}= \\frac { 2 - 6 } { 4 } = - \\frac { 4 } { 4 } = - 1{/tex}{tex}y=\\frac{my_2+ny_1}{m+n}{/tex}{tex}y _ { 1 } = \\frac { ( 1 ) ( 8 ) + ( 3 ) ( 2 ) } { 1 + 3 }{/tex}{tex}= \\frac { 8 + 6 } { 4 } = \\frac { 14 } { 4 } = \\frac { 7 } { 2 }{/tex}So,\xa0{tex}\\mathrm { P } \\rightarrow \\left( - 1 , \\frac { 7 } { 2 } \\right){/tex}Also, Q divides AB in the ratio 1 : 1 i.e.Q is the mid point of AB{tex}x _ { 2 } = \\frac { - 2 + 2 } { 2 } = 0{/tex}{tex}y _ { 2 } = \\frac { 2 + 8 } { 2 } = \\frac { 10 } { 2 } = 5{/tex}So,\xa0{tex}Q \\rightarrow ( 0,5 ){/tex}and, R divides AB in the ratio 3 : 1{tex}\\therefore x _ { 2 } = \\frac { ( 3 ) ( 2 ) + ( 1 ) ( - 2 ) } { 3 + 1 }{/tex}{tex}= \\frac { 6 - 2 } { 4 } = \\frac { 4 } { 4 } = 1{/tex}{tex}y _ { 3 } = \\frac { ( 3 ) ( 8 ) + ( 1 ) ( 2 ) } { 3 + 1 }{/tex}{tex}= \\frac { 24 + 2 } { 4 } = \\frac { 26 } { 4 } = \\frac { 13 } { 2 }{/tex}So,\xa0{tex}\\mathrm { R } \\rightarrow \\left( 1 , \\frac { 13 } { 2 } \\right){/tex} | |

-5+(-8)+(-11)+....+(-230) |
| Answer» –5 + (–8) + (–11) + …. + (–230)This is an AP.Here, a = –5d = –8 –(–5) = –8 + 5 = –3l = –230Let the number of terms of the AP be nWe know thatl = a + (n - 1)d{tex} \\Rightarrow {/tex}\xa0-230 = -5 + (n - 1) (-3){tex} \\Rightarrow {/tex}\xa0(n - 1) (-3) = -230 + 5{tex} \\Rightarrow {/tex}\xa0(n - 1) (-3) = -225{tex} \\Rightarrow n - 1 = \\frac{{ - 225}}{{ - 3}} = 75{/tex}{tex} \\Rightarrow {/tex}\xa0n = 75 + 1{tex} \\Rightarrow {/tex}\xa0n = 76Again, we know that{tex}{S_n} = \\frac{n}{2}(a + l){/tex}{tex} \\Rightarrow {S_{76}} = \\frac{{76}}{2}\\left[ {( - 5) + ( - 230)} \\right]{/tex}{tex} \\Rightarrow {/tex}\xa0S76 = 38(-235){tex} \\Rightarrow {/tex}\xa0S76 = -8930Hence, the required sum is -8930. | |
