Which exponential function is represented by the table?

The answer is f(x) = 0.8(2^x)

Step-by-step explanation:

∵ f(x) = 0.8(2^x)

∵ x = -2 ⇒ ∴ f(-2) = 0.8(2^(-2)) = 0.2

∵ x = -1 ⇒ ∴ f(-1) = 0.8(2^(-1)) = 0.4

∵ x = 0 ⇒ ∴ f(0) = 0.8(2^(0)) = 0.8

∵ x = 1 ⇒ ∴ f(1) = 0.8(2^(1)) = 1.6

∵ x = 2 ⇒ ∴ f(2) = 0.8(2^(2)) = 3.2

∴ The answer is f(x) = 0.8(2^x) ⇒ The fourth answer

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.
