Given f(x)=4x^2+6x and g(x)=2x^2+13x+15, find (f/g)(x) a. (f · g)(x) = –6x – 4 b. (f · g)(x) = –8x2 – 4x c. (f · g)(x) = –6x – 2 d. (f · g)(x) = –16x2 – 4x

a

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.
