Answer:

Step-by-step explanation:

I don’t know why they bother teaching recursive formulas as the explicit is almost always used :)

For 2,9,16,23...

Recursive is a(n+1)=an+7

Explicit is an=2+7(n-1)

(or more neatly an=7n-5)

For 2,14,98,686...

Recursive is a(n+1)=7an

Explicit is an=2(7^(n-1))

(or (2/7)7^n )

Answer:

height for the building = 551.8 ft

Step-by-step explanation:

The info given describes the shape of a right triangle.

Thus:

Reference angle = Angle of elevation = 23°

Opposite side = height of the building = ?

Adjacent side = 1,300 ft

Apply trigonometric function, TOA:

Tan 23 = Opp/Adj

Tan 23 = Opp/1,300

1,300 × Tan 23 = Opp

551.817261 = Opp

Opp ≈ 551.8 ft

height for the building = 551.8 ft
