A car was valued at $29,000 in the year 1994. The value depreciated to $11,000 by the year 2001.
A) What was the annual rate of change between 1994 and 2001?
r=
Round the rate of decrease to 4 decimal places.

rate of change is: -$2571.4286 per year

Step-by-step explanation:

Recall that he rate of decrease is given by the following formula:

That is the final value of the car ($11000) minus its initial value ($29000), all divided by the time elapsed (7 years between 1994 and 2001). Then the formula gives:

Notice the negative sign due to the fact that the value is decreasing with the years.

Normally, this rate will be considered a rate of DECREASE, and its value given as $2571.4286 (without the negative sign, since the word "DECREASE" implies already a negative rate of change.

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.

any of them that add up to 180 degrees.
