Please, post just one problem at a time, or (if you post more than one), indicate which one you want to focus on first. Even more important, please do whatever you can to get started on each problem; I'm sure you know at least some basics.
What does "intersecting" mean? Look it up if you're not sure.
Then what would "two intersecting lines" look like? Draw the graph, or at least explain in words what the graph would look like.
Answer:
b. y=sec(x/3) and y=-1
Step-by-step explanation:
sec(x/3) + 4 > 2 − sec(x/3)
2 sec(x/3) > -2
sec(x/3) > -1
Graph y = sec(x/3) and y = -1.
Answer:
stars.
Step-by-step explanation:
We have been given that a particular galaxy has a total mass of 
grams and the average star in that galaxy has a mass of 
grams. We are asked to find the number of stats in the galaxy.
To find the number of stats in the given galaxy, we will divide total mass of galaxy by mass of an average star in the galaxy as:
Using exponent property 
, we will get:
Therefore, there are approximately 1000,000,000,000,000,000,000,000 stars in the given galaxy.
