Answer:

3.33 miles per hour

Step-by-step explanation:

The total distance traveled by the hiker is 5 * 2 = 10 miles, and the total time travelled is 2 + 1 = 3 hours.

So, to find the average speed of the entire trip, we can use the formula:

distance = speed * time

With distance = 10 and time = 3, we have:

10 = speed * 3

speed = 10/3 = 3.33 miles per hour.

A new car was valued at $28,000, and it's value depreciated to $14,000 over the next 3 years. Use the exponential equation for d
kompoz [17]
The exponential equation (in thousands) is:
V = 28 e^{-rt}
plug in t=3 yrs, and solve for 'r'.
14 = 28 e^{-3r} \\  \\ \frac{1}{2} = e^{-3r}  \\  \\ ln(\frac{1}{2}) = -3r \\  \\ r = \frac{ln(\frac{1}{2})}{-3} = 0.231 = 23.1%

Find value of car when t = 10
V = 28e^{-2.31} = 2.779
