Answer:

the correct answer is d

on a tall, dry mountain peak

Explanation:

A telescope is an instrument that allows the observation of distant bodies whose light is very dim, for this the telescope concentrates a large amount of light with large diameter lenses or mirrors.

The location of a telescope must take into account several aspects:

* The most important that there are no nearby lights that disturb the observation, so it must be away from cities and other strong light sources.

* The climate should be as stable as possible with few temperature variations, to prevent the optical surfaces from fogging up and reducing the thermal expansion that changes the length of the instrument.

* You must choose a place with little rain and therefore little amount of clouds

Based on these needs we can answer which luxury will be the most suitable

a) There is a lot of light nearby

b) there is a lot of humidity and wind

c) there is a lot of light

d) This is an ideal place with low light, low humidity and stability in the climate

e) lots of humidity and light

so the correct answer is d

Please explain how to solve 17 and 18
andriy [413]

Answer:

17. h = l − l cos θ

18. 1.40 m

Explanation:

Let's call d the height of the triangle.  We can then say:

h = l − d

Using trig, we can write d in terms of l and θ:

d = l cos θ

h = l − l cos θ

If l = 6 m and l cos θ = 40°:

h = 6 − 6 cos 40

h ≈ 1.40
