Polynomials can have REAL ZEROS or COMPLEX ZEROS. Real Zeros to a polynomial are POINTS where the graph crosses the x-axis when y=0. When we graph each function, we can see these points. Complex Zeros are the SOLUTIONS of the equation that ARE NOT VISIBLE on the graph.
They are not. The easiest way to tell this is by multiplying the last number of each parenthesis together. This should always result in the last number in the equation. However, -8*5 does not equal -30, so these are not the true factors.
Answer:
5 min
Step-by-step explanation:
time taken=distance required to travel/speed of train
total distance train have to cover to just left the tunnel is (lenght of tunnel+length of train) =2km+250m
=2250m
speed of train is 27km/hr
multiply 5/18 to convert in m/s
i.e, (5/18)×27=7.5m/s
now time taken =2250m/(7.5m/s)
=300s
and,300s =5min
