The world’s fastest train travels about 162 mi/h. estimate how far the train travels in 4.75 h.

770 miles

Step-by-step explanation:

The world's fastest train travels about 162 miles per hour.

The speed of train = 162 miles/hour

Train travels in 4.75 hour = 162 × 4.75

                                          = 769.5 miles ≈ 770 miles

The train travels almost 770 miles in 4.75 hours.

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.

i just took the test, the correct answer is .. 31.5 in.
