What is the explicit formula for the arithmetic
sequence?
an = 1.2 + (n - 1)1.5
an = 1.5 + (n - 1)1.2
an = 1.5 + (n - 1)3.9
an = 3.9 + (n - 1)1.5

it has the same slope and a different y-intercept

hope this : )

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.

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
