– 5y + 6 at (i) y = 2 (ii) y = – 2

2. A rabbit covers y metres distance by walking 10 metres in slow motion and the remaining by x

jumps, each jump contains 2 metres. Express this information in linear equation.

3. In the given figure, find the value of x and y where O is the centre of the circle.

4. Find the area of an equilateral triangle with side 2 3 cm.

5. Two coins are tossed simultaneously 500 times, and we get

Two heads : 105 times One head : 275 times

Find the probability of getting 0 head.

6. Find the height of cone, if its slant height is 34 cm and base diameter is 32 cm.

Answer 1

1
let y=2 then
p (y)=(-5×2)2)+6
= (-5×4)+6
-20+6
=-14
