A small telescope magnifies
WARRIOR [948]

The observatory telescope has 22 times the magnifying power compared to the small telescope.

Data;

  • small telescope = 150 times
  • large telescope = 3300

<h3>Division of Numbers</h3>

To solve this question, we have to divide the large telescope by the small telescope to calculate it's magnifying power.

x = \frac{3300}{150}=22

The magnification of the observatory telescope is 22 times greater or larger than the small telescope.

dimaraw [331]

Answer:

Step-by-step explanation:

The graph of the absolute value function looks like a V that opens UP and has its vertex at the origin, (0, 0).  There are no restrictions on the input, x, so the domain is (-infinity, infinity).

On the other hand, this function has no values less than zero.  Its range is

[0, infinity).
