Answer:
315 m/s = 1134 km/h
Step-by-step explanation:
Multiply the speed value by 3.6
315 x 3.6 = 1134
Answer:
c. In 2 seconds, the commuter train travels 120 feet.
Step-by-step explanation:
Given
The attached graph
Required
What does x-coordinate of 2 represents
Represent this coordinate with (x,y)
From the graph:
when 
Note that:
x = time and y = distance
So:

Which means:
At 2 seconds, the train has travelled a distance of 120ft
<em>From the list of options, (c) is correct</em>
H(x) = x - 5
However, it had a domain of all real numbers such that x does not equal 3, since that would cause you to divide by 0.
X=-2
5-4=1
so whatever is square rooted must be equal to 1
1 squared is 1
-2+3 is one
The answer is -29, hope this helps
