Answer:
21.09 ft/s
Step-by-step explanation:
The first step is to create the ratio of speed/time.
Next we must simplify
Next we must convert 14 miles in to feet. There are 5280 feet in a mile.
14 * 5280ft = <u>75,920 feet</u>
Now for hours into seconds.
1 hour = 60 min, 60 min = 3600 seconds
Our new ratio is \frac{75920ft}{3600sec}
simplify.
75920ft / 3600sec = 21.09ft/s
In interval notation the domain would be: (-infinity,-2]U[2,3)U(3,+infinity)
Answer:
Slope = 3
Step-by-step explanation:
Slope = 
Slope = 
Slope = 
Slope = 3
Answer: Slope = 3
To find the mean, you add up the numbers and divide by
how many numbers there are.
So if the mean of 'A' and 'B' is 40, then A + B = 80 .
And if the mean of 'B' and 'C' is 35 then B + C = 70.
==========================================
You said that (A + B) + C = 100 .
From something else that you said, I noticed that A + B = 80 .
So I can write (80) + C = 100
Subtract 80 from each side: C = 20
==========================================
I also noticed, from what you said, that B + C = 70 .
So I can write B + 20 = 70
Subtract 20 from each side: B = 50
==========================================
Now I know that C = 20 and B = 50.
Finally, you said that A + B + C = 100 ,
So I can write A + 50 + 20 = 100
Combine like terms on the left: A + 70 = 100
Subtract 70 from each side: A = 30
==========================================
<em> A = 30</em>
<em> B = 50</em>
<em> C = 20</em>
