Which expression is equivalent to (tan(theta/2))(-sin theta)? -1-cos(theta)
-1+cos(theta)
1+cos(theta)
1-cos(theta)

i got 86 for this

hope this !

if you need an explanation just ask

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew

40 minutes

step-by-step explanation:

add the time and multiply by 2

the answer is b.
