Given the function g(x)= 5-x^2, simplify the bottom

Step-by-step explanation:

We are given the function and the expression

First, we must substitute in x+h into g(x) and substitute in g(x) into the expression

Next, we can simplify by multiplying out the exponents and then combine like terms

Next, we can divide the numerator by the denominator to get

Lastly, we can substitute in 0 for h

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.
