(14) the circle equation whose centre lies on the straight line y = 5 x and touches
x-axis could be
(a) (x - 2)2 + (y – 1)2 = 4
(b) (x – 4)2 + (y - 2)2 = 16
(c) (x - 2)2 + (y - 4)2 = 16 (d) (x – 4)2 + (y – 2)2 = 4
(15) area of the square whose vertices lie on the circle : x2 + y2 - 4 x+6 y +4=0
is square units.
(a) 6
(b) 9
(c) 12
(d) 18
(16) the geometrical centre of square abcd is the origin and its side length is 2v3
, then the equation of the circle that touches its sides is
(a) x2 + y2 = 3
(b) x2 + y2 = 12
(c) x2 + y2 = 6
(d) (x -v3) + (y-v3 )' = 3

Me. drysdale earned 906.25 in interest in one year on money that he had deposited in his local bank if the bank paid an interest rate of 6.25% how much money did mr. drysdale deposit

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?

Which of these side lengths could form a triangle a) 2 cm , 2 cm , 4 cm b) 3 cm , 5 cm , 10 cm c) 3 cm , 4 cm , 5 cm d) 4 cm , 8 cm , 15 cm
