I just need help with this one pleas
Solve: cos (2x)= -3^(1/2)/2

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

4x and 6y

im not sure though

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
