8.3. We now study the groups from Problem 8.2. 1. How many elements does each of the multiplicative groups have? 2. Do all orders from above divide the number of elements in the corresponding multiplicative group? 3. Which of the elements from Problem 8.1 are primitive elements? 4. Verify for the groups that the number of primitive elements is given by φ(|Z∗ p|).

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

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
