Answer 1

$i) Point \: (3,6) \: lies \:on \: \pink{ First \: Quadrant }$

$ii) To \: find \: zeroes \: of \: x^{2} - 9, \: we$

$\:take\: x^{2} - 9 = 0$

$\implies x^{2} = 9$

$\implies x = \pm \sqrt{9}$

$\implies x = \pm \sqrt{3^{2}}$

$\implies x = \pm 3$

Therefore.,

$\green { -3, 3 \:are \: zeroes \:of \: x^{2} - 9 }$

$10) First \: five \: odd \: numbers \: are$

$1,3,5,7,9$

$Mean = \frac{ 1+3+5+7+9}{5}$

$= \frac{25}{5}$

$= 5$

Therefore.,

$\red{ mean \: of \: First \: five \: odd \: numbers}$

$\green { = 5 }$
