Given the arithmetic sequence an = −5 + 3(n − 1), what is the domain for n? all integers where n ≥ 1 all integers all integers where n ≥ 0 all integers where n > 1

All integers where n ≥ 1

Step-by-step explanation:

We know that the domain of any sequence is the set of natural numbers .

Therefore, the domain for the given arithmetic sequence is the set of natural numbers.

Since we know that the set of natural numbers starts with digit 1.

Therefore, the domain of the given arithmetic sequence is all integers where n≥1.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
