What is the sum of the first 20 terms of the series 3 + 14 + 25 + 25 + 36 +

Fynjy0 [20]

Answer:

$S _{20} = 2150$

Step-by-step explanation:

$a _{1} = 3 \\ a _{2} = 14 \\ d = a _{2} - a_{1} = 14 - 3 = 11 \\ n = 20$

$S _{n} = \frac{n}{2} (2a + (n - 1)d) \\ \\ S _{20} = \frac{20}{2} (2(3) + (20 - 1) \times 11) \\ \\ S _{20} = 10 \times (6 + 19 \times 11) \\ S _{20} = 10 \times (6 + 209) \\ S _{20} = 10 \times 215 \\ S _{20} = 2150$

Amelia is looking at the top of a lighthouse. She knows she is 30 feet from the base of

statuscvo [17]

Answer:

25.7 feet

Step-by-step explanation:

We are solving a right angled triangle.

We are the Trigonometric function of Tangent

tan θ = Opposite side/Adjacent

Angle of Elevation = θ = 34°

Opposite side = Height

Adjacent = 30 feet

tan 34° = Opposite side/30 feet.

Opposite side = tan 34° × 30 feet

Opposite side = 20.235255505 feet

The height of the light house =

Opposite side(height) + Amelia's height

20.235255505 feet + 5.5 feet

= 25.735255505 feet

Approximately to the nearest tenth ≈ 25.7 feet
