Pls help I’m timed thanks

Picture 1: b

Picture 2: d

Picture 3: c

Step-by-step explanation:

Hi there,

For Picture 1, to solve for an inverse function, just simply solve for x. Since the closest you can get is arccos(πx)=2y+6, you just

solve for cosine as a function: cos(2y+6)=πx and solving for x:

x= (1/π)cos(2y+6)    but since variable choice is arbitrary, you can now redefine y and x:

y= (1/π)cos(2x+6)

For Picture 2, tanx is equivalent to sinx/cosx and cscx is just the reciprocal of sinx. So, it becomes:

We have already been giving the cosine value of 2, and its inverse is thus 1/2.  

For Picture 3, I would recommend revisiting polar coordinates.

Polar coordinates are in the form (r, θ).

  and  θ . Recognize there are two possible radii, depending on what side of the circle you start from!

thanks,

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
