Answer: D ( 7,3 7,6 7,9 7,12 7,15)

Step-by-step explanation:

A- (-4, 0, 7, 3, -7) There are no repeating domains, therefore, this is a function

B- (1, 3, 5, 7, 9) The domain does not repeat, therefore this is a function

C- (4, 8, 12, 16, 20) The domain does not repeat, therefore this is a function

D- (7, 7, 7, 7, 7) The <u>entire</u> domain repeats, therefore this <em><u>cannot </u></em> be a function

Correct answer is D ( 7,3 7,6 7,9 7,12 7,15)

klio [65]

Answer:

18432 km/h

Step-by-step explanation:

It is given that a sound wave travels through iron at a rate of 5120 m/s.

We know that

1 km = 1000 m

1 hour = 60 minutes

1 minutes = 60 second

Using these conversions we get

1 m = 0.001 km

1 hour  = 3600 second

5120\text{ m/s }=5120\times 0.001\times 3600\text{ km/h}

5120\text{ m/s }=18432\text{ km/h}

Therefore, the sound wave travels through iron at a rate of 18432 km/h.
