Decide whether the data in the table represent a linear function or an exponential function. explain how you know.

The data in the table represent a linear function because there is a common difference of -8.

Step-by-step explanation:

A linear function always forms a straight line. Mainly no curves allowed.

While drawing a graph if the line appears to be straight then it is linear function.

From the given the table the constant value is -8.

It forms a negative slope on the positive x-axis.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
