Answers & Solutions:<\/strong><\/span><\/p>\n

1)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

Equation of circle\u00a0$x^2+y^2+2gx+2fy+c=0$<\/p>\n

It passes through\u00a0(0,0), (4,0) and (3,9). Substitute each point in the above equation:<\/p>\n

=> On substituting the value (0,0) in the above equation, we obtain: $c=0$<\/p>\n

=> On substituting the value (4,0) in the above equation, we obtain:\u00a0 $16+0+8g+0 = 0$ ; $g=-2$<\/p>\n

=>\u00a0On substituting the value (3,9) in the above equation, we obtain: $9+81-12+18f = 0$ ;\u00a0$f= -13\/3$<\/p>\n

Radius of the circle r\u00a0<\/strong>=\u00a0$\\sqrt{\\ g^2+f^2-c}$ =>\u00a0$r^2=\\frac{205}{9}$<\/p>\n

Therefore, Area =\u00a0$\\pi\\ r^2=\\frac{205\\pi\\ }{9}$<\/p>\n

2)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

We have been given 2 vertices. It is possible that they are adjacent vertices or opposite vertices.<\/p>\n

Case 1: The given points are on a diagonal. We come up with the following square<\/p>\n

<\/p>\n

Hence (-5,5) satisfies the condition for a vertex of the square.<\/p>\n

Case 2: The given\u00a0points are on a side. We come up with the following 2 possible squares:<\/p>\n

<\/p>\n

Hence (15,-5)\u00a0satisfies the condition for a vertex of the square.<\/p>\n

<\/p>\n

Hence (-5,15) satisfies the condition for a vertex of the square.<\/p>\n

Hence, we can see all the mentioned points apart from (5,15) satisfies the condition for the vertex of the square.<\/p>\n

3)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Let us take intersection of\u00a0$l_1 : 3x -2y +18 =0 $ , $l_2 : 2x-y+7 =0 $.<\/p>\n

$ l_1 -2l_2 : -x+4 = 0$ or $x=4$ which gives y=15. Thus (4,15) is the point of intersection<\/p>\n

Let us take intersection of\u00a0$l_2 : 2x-y+7 =0 $ and $l_3 : 5x-2y+6 =0 $<\/p>\n

$ l_3 – 2l_2 :\u00a0x-8 = 0$ or $x=8$ which gives $y=23$<\/p>\n

Let us take intersection of $l_1 : 3x -2y +18 =0 $ and\u00a0$l_3 : 5x-2y+6 =0 $<\/p>\n

$l_3 – l_1 : 2x-12 = 0$ or $x=6$ which gives $y=18$<\/p>\n

Thus point of intersection are (4,15), (8,23)\u00a0and (6,18)<\/p>\n

length of side 1 =\u00a0$\\sqrt{\\left(8-4\\right)^2+\\left(23-15\\right)^2}=\\sqrt{\\ 4^2+8^2}=4\\sqrt{\\ 5}$<\/p>\n

length of side 2 =\u00a0$\\sqrt{\\left(8-6\\right)^2+\\left(23-18\\right)^2}=\\sqrt{\\ 2^2+5^2}=\\sqrt{\\ 29}$<\/p>\n

length of side 3= $\\sqrt{\\left(6-4\\right)^2+\\left(18-15\\right)^2}=\\sqrt{\\ 2^2+3^2}=\\sqrt{\\ 13}$<\/p>\n

Sum of square of sides = 80+29+13 =122<\/p>\n

4)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

<\/p>\n

Since it is a right angle triangle, circumradius\u00a0 =\u00a0$\\frac{hypotenuse}{2}$ =\u00a0$=\\ \\frac{\\ \\sqrt{\\ 4^2+4^2}}{2}=\\frac{4\\sqrt{\\ 2}}{2}=2\\sqrt{\\ 2}$<\/p>\n

inradius =\u00a0$\\frac{area}{semi-perimeter}=\\frac{\\frac{1}{2}\\left(4\\right)\\left(4\\right)}{\\frac{\\left(4+4+4\\sqrt{\\ 2}\\right)}{2}}\\ =\\frac{8}{4+2\\sqrt{\\ 2}}\\ =\\frac{4}{2+\\sqrt{\\ 2}}$<\/p>\n

Ratio =\u00a0$\\frac{\\left(\\ \\frac{4}{2+\\sqrt{\\ 2}}\\right)}{2\\sqrt{\\ 2}}=\\frac{\\sqrt{\\ 2}}{2+\\sqrt{\\ 2}}$<\/p>\n

5)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

x1\u2019 = 2*d – x1
\ny1\u2019 = 2*d*a – y1 + 2*c
\nand
\nd=(\ud835\udc651+(\ud835\udc661\u2212\ud835\udc50)\u2217\ud835\udc4e)\/(1+\ud835\udc4e2)
\nd=(3+(4-6)*(-3))\/(1+9)
\nd=9\/10
\nx1\u2019 = 2*9\/10-3
\n=-6\/5
\ny1\u2019 = 2*9\/10*(-3)-4+12
\n=13\/5<\/p>\n

6)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

if P” is (2,5) ; reflection P’ will be (5,2) which if reflected along x axis would be (5,-2)<\/p>\n

7)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

The point of intersection of lines bx+4y+1=0 and ax+8y+1=0 is\u00a0$\\left[\\frac{1}{a-2b},\\frac{1}{4}\\cdot\\frac{\\left(b-a\\right)}{a-2b}\\right]$<\/p>\n

Substituting these points in cx+12y+1 = 0 , we get\u00a0$c\\cdot\\frac{1}{a-2b}+12\\cdot\\frac{1}{4}\\cdot\\frac{\\left(b-a\\right)}{a-2b}+1=0$
\n=> c + 3(b -a) + (a – 2b) =\u00a0 0
\n=> b+c = 2a<\/p>\n

8)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

(x , y) = \u00a0($\\frac{mx_{2}+nx_{1}}{m+n}$ , $\\frac{my_{2}+ny_{1}}{m+n}$)<\/p>\n

(x , 0) = \u00a0($\\frac{m-4n}{m+n}$ , $\\frac{4m+n}{m+n}$)<\/p>\n

4m+n = 0<\/p>\n

4m = -n<\/p>\n

m\/n = -1\/4<\/p>\n

So the answer is option A.<\/p>\n

9)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

slope = $\\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\\frac{2+3}{5-x}=\\frac{5}{5-x}=\\frac{-2}{3}$<\/p>\n

$\\rightarrow 15 = -10 + 2x$<\/p>\n

$\\rightarrow x = \\frac{25}{2} = 12.5$<\/p>\n

so the answer is option C.<\/p>\n

10)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

centroid = $(\\frac{x_{1}+x_{2}+x_{3}}{3} , \\frac{y_{1}+y_{2}+y_{3}}{3})$ = $(\\frac{2-4+5}{3} , \\frac{5+0+4}{3})$ = $(1 , 3)$<\/p>\n

so the answer is option B.<\/p>\n
