Use the graph to write the explicit rule of the arithmetic sequence. Question 14 options:

A)

ƒ(n) = 3 + 2(n – 1)

B)

ƒ(n) = 9 + 2(n – 1)

C)

ƒ(n) = –3 + 2(n – 1)

D)

ƒ(n) = 5 + 3(n – 1)

b

step-by-step explanation:

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

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.
