(a) 10 X = 360
x = 36

(b) A + D = B + C = 360


For, me it was little bit tricky !

Guys do we need to learn matrixes by heart for rotations too?

I'm doing the same year, can u explain 13b please

for the gradient draw the tangent . mark 2 point and find gradient. i cant to dat on screen properly

How do you do these type of questions?

2^a x 3^b x 7^c = 500
find a and b and c.

P.S. I know question is incomplete - wrong etc etc etc. But you get the point :v

is this frm indices topic?

did u give the correct values???
so i think u need to factorize 500 which will be equal to 2^2 * 5^3

Q10:b

Kevin takes T time with 100 speed.
Jane takes ___ time with 110 speed.

T is inversely proportional to speed.

So T = k/speed.

Put 100 and T in, and you get k=100T

Then, put 110 as speed, and you get the time for Jane, 100T/110

Genius
nd u say u dont knw anything

Q10:b

Kevin's time = T

Kevin's speed = d/T

Jane walks 10 % faster than Kevin (her speed is 10 % more than Kevin)

Jane's speed = (d/T) * (110/100)


Applying the speed = distance/ time formula


(d/T) * (110/100) = d / x

Find x
