Division can be looked at as breaking things into parts. For example, with you 2 ÷ 2 = 1 that can be looked at as you have two chocolate bars and 2 people who want those chocolate bars. How can you fairly give those 2 people 2 chocolate bars? Well you would give them 1 each? It'd be the same thing with 5 people and 5 chocolate bars. Any number divided by itself with always be one, no matter what. Unless you have 0/0 or infinity/infinity , but those are different scenarios.
There are an infinite number of solutions, so I don't plan to list them all.
I'll list two of them, and then describe how to get all of the rest.
You said that <u>2cos(x) - 1 = 0</u>
Add 1 to each side: 2cos(x) = 1
Divide each side by 2: cos(x) = 1/2
The angles whose cosine is 1/2 are 60 degrees, 300 degrees,
and any multiple of 360 degrees added to either of those.
b= 14 because the formula to find a triangles area is 0.5bh. So, you take 147 and divide it by 21 then multiply the answer of that (which is 7) by 2 because the reciprocal of 0.5 is 2.
Answer:
Positive linear.
Step-by-step explanation:
The points are gradually rising as x increases.
