The equation given is f(x) = x^2 - 12x + 27
Based on its form, it is a parabola. First, factor the quadratic equation:
f(x) = (x-9) (x-3)
Plot in the x-y plane, assign values of x and solve for the values of y.
x y
1 16
2 7
3 0
0 27
-1 40
-2 55
-3 72
V = length x width
5 x 8 = 40
3 x 4 = 12
40 + 12 = 52 (answer for #3)
4 x 6 = 24
14 - 6 = 8
8 x 9 = 72
24 + 72 = 96 (answer for #4)
7 x 6 = 42
3+6+3 = 12
5 x 12 = 60
60 + 42 = 102 (answer for #5)
The speed of the train in meters per second is equal to 22.36m/s.
As given in the question,
Speed of the train is equal to 50.0 miles per hour
1 mile = 1.61 kilometers
1 kilometers = 1000 meters
1 hour = 3600 seconds
Therefore,
50.0 miles per hour = 50 × 1.61
= 80.5 kilometers per hour
Convert speed from kilometers per hour to meter per second
80.5 kilometers/hour = (80.5 ×1000) / 3600
= 22.36 meters per second
Therefore, the speed of the train in meters per second is equal to 22.36m/s.
