Which of the following functions contains the point (pi/4, 4)?

f(x) = 4sin (2x)
f(x) = 1/4 sin (2x)
f(x) = 1/2 sin (4x)
f(x)= 4sin (1/2 x)

This is the answer I got for edge 2020. Hope this reaches someone who needs it.

Step-by-step explanation:

It is what it is...

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
