Which sets of numbers represent geometric sequences? Check all that apply.

mart [117]

Answer:

Geometric sequences are below in bold.

Step-by-step explanation:

First one is 2/5, 2/10, 2/20, 2/40

2/10 = 2/5 * 1/2 ; 2/20 = 2/10 * 1/2

This is geometric with common ratio 1/2.

Second is 11/12, 8/12, 5/12, 2/12

This is not geometric It is arithmetic with common difference -3/12.

25, 19, 13, 7.... is arithmetic with d = -6

4, 12, 36, 108

12 = 3*4, 36 = 3*12 and so on

This is geometric with r = 3.

-5, 5, -5, 5,...

Each term is obtained from the prievious by multiplying by - 1. S

this is geometric with r = -1.

-3, 0, 3, 6 is arithmetic with d = 3.

-8, -2, 1/2, 1/8

This is not geometric as there is no common ratio.

At a point on the ground 20 feet from a building, a surveyor observes the angle of inclination to the top of the building to be

Bess [88]

Answer:

34.64 ft

Step-by-step explanation:

Distance from the building = 20 ft

Angle of inclination = π/3 radians

The tangent of the angle of inclination must equal the height of the building divided by the distance of the observer from the building:

$tan( \pi/3) = \frac{h}{20} \\h = 20*1.73205\\h=34.64\ ft$

The building is 34.64 ft tall

Answer:

106 m^2

Step-by-step explanation:

First multiply the shaded area:

12 * 10 = 120

Then multiply the white space:

7 * 2 = 14

Then subtract the white space from the shaded area to find the area of only the shaded area.

120 - 14 = 106

Final answer: 106 m^2

I hope this helps!
