Write an<br> explicit formula for an, the nth term of the sequence 21, 27, 33, ....
anygoal [31]

Answer:

Step-by-step explanation:

Remark

This is an arithmetic series. Each term differs by 6 from the previous one.

Givens

a1 = 21

d = 6

Formula

a_n = a1 + (n - 1)*d

Sample

Try it.

Let's let n = 3 which we have the answer for.

a_3 = 21 + (3-1)*6

a_3 = 21 + 2 * 6

a_3 = 21 + 12

a_3 = 33

That's exactly what the 3rd term is.

Csc^2x – 5 csc x = 0
kompoz [17]

Answer:

x ≈ 11.5° or 168.5°

Step-by-step explanation:

csc² x − 5 csc x = 0

Factor:

csc x (csc x − 5) = 0

Set each factor to 0 and solve:

csc x = 0

sin x = undefined

no solution

csc x − 5 = 0

csc x = 5

sin x = 1/5

x = arcsin(1/5)

x ≈ 11.5° or 168.5°
