Which function describes the sequence 4, 8, 16, 32 … A. f(n) = 2n
B. f(n)=4n + 2
C. f(n)=4(2)n−1
D. f(n)=(n−1)2+3

I think that the answer is 2 power n , so A is the correct choice .

idk the answer but just put a

step-by-step explanation:

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.
