A bullet train travel at the speed of 365 km/h. In august 2001, singapore's national record for the men's 100 m sprint was set at 10.37 sec .How many times is a bullet train as fast as the fastest singaporean sprinter?

Therefore bullet train is 10.5 times as fast as the fastest Singaporean sprinter.

Step-by-step explanation:

Given that,

A bullet train travels at the speed off 365 km/h.

365 km/h

   [ ∵1 km= 1000 m and 1 h = 3600 s]

m/s

We know that,

Singapore's national record for the men's 100 m sprint was set at 10.37 sec.

The speed of Singaporean sprinter is

Now,

=10.5

Therefore bullet train is 10.5 times as fast as the fastest Singaporean sprinter.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
