Domain means all the x-values include in the graph.
In this case the graph starts including x-values at 0 and all x-values that are greater then 0.
In other words x can be zero or anything larger
Technically you would show this like so:
x ≥ 0
You use the inequality symbol with the bar underneath because you want to show that 0 is included in the domain. It faces away from the zero and towards the x because x can be larger then 0 not smaller.
I guess in this case you wouldn't be including 0 so your answer is:
B. x > 0

The answer is 0.00347222222
Using: A^2+b^2=c^2
A&b= (√10)^2=10
10+10=c^2
20=c^2
(take the square root of 20)
c=2√5
Your answer is D
Answer:
75 mph
Step-by-step explanation:
A biker must circle a 12-mile track twice. His average speed must be 60 mph.
So, the average time required to cover the distance is 
hours.
Now, on his first lap, he averaged 50 mph.
So, he covered this 12 miles track in 
hours.
Hence, he has to cover the next 12 miles track in (0.4 - 0.24) = 0.16 hours.
Therefore, his average speed in the second round must be 
mph to qualify. (Answer)
Answer:
30
Step-by-step explanation:
If Rodger has 15 cups of punch. There are glasses that have a 1/2 cup capacity. This means he is going to divide a 15 cups into 1/2 cups.
15/1 x 2/1 = 30/1
This means he will have 30 cups to fill.
