Let f(x)=20/1+9e^3x .

what are the asymptotes of the graph of f(x) ?

select each correct answer.

y = 3

y = 0

y = 9

y = 20

y = 0 and y = 20

Step-by-step explanation:

The given function is

There is no vertical asymptotes because the denominator will never be zero.

Horizontal asymptotes are given by

Take the constant 20 out of the limit

Now, we can further simplify as follows

Similarly, the second horizontal asymptote is

We can simplify this limit as we did the previous one

Hence, asymptotes of the graph of f(x) are

y = 0 and y = 20

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.
