Help a friend out plz! Graph on the domain {-pi, 0], where a = 3 and b =2 and include the orientation. x(t) = acos((a+b) t) & y(t) = acos((a-b)t) Use the parametric equations for integers a and b.

the answer is c 150

step-by-step explanation:

where are the graphs?

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
