Step-by-step explanation:
To evaluate the approximate square root of 7 you would take the two closest numbers which happen to be 
and 
so you look to see where your 
falls closest which it is closer to 9.
If we simplify our and you would get 2 and 3
Since is closer to the we would say the answer is approximately 2.6 or 2.7
Hope this helps! Good luck!

Step-by-step explanation:
Given the following :
40 metres covered in 6 seconds
Max speed attained after 6seconds
75 meters covered after 11 seconds
Average Speed for first 40 meters :
Speed = distance / time
Speed = 40m / 6s
Speed = 6.67m/s
To obtain the maximum speed :
Next (75 - 40) meters = 35 meters was covered in (11 - 6)seconds = 5 seconds
Speed at this point is maximum :
Hence, maximum speed = (35m / 5s) = 7m/s
Suppose, Manuel runs for an additional z seconds after reaching max speed :
Distance from starting line 6+z seconds after race started?
Distance after 6 seconds = 40 metres
Distance after z seconds = 7 * z
Total distance = (40 + 7z)
What is Manuel's distance from the starting line x seconds after the race started (provided x≥6x)?
Distance for first 6 seconds = 40 meters + distance covered after 6 seconds = (7 * (x-6))
40 + 7(x - 6)

Answer:
They are parallel.
Step-by-step explanation:
They have the same slope, 7, and different y-intercepts, 4, -1/4, so they are parallel.
Answer:
0
Step-by-step explanation:
f(x) = -3x^2 + 6x
Let x=2
f(2) = -3*(2)^2 + 6(2)
=-3(4) +12
= -12+12
=0
