Answer:
C(t) = $28,000(0.811)^t (Answer A)
Step-by-step explanation:
The value of the car is decreasing. Thus, by the end of the first year of ownership, the car will have the value $28,000(1 -0.189)^1, where the "-0.189" represents DECAY instead of GROWTH.
Please use " ^ " to indicate exponentiation.
Then the desired formula is C(t) = $28,000(0.811)^t (Answer A)
A fisherman travels downstream at full speed to his favorite fishing spot.
<span>The stream is running at a rate of 5 miles per hour, and he takes an hour to get to the fishing hole. </span>
<span>He catches 5 fish and calls it a day. </span>
<span>He takes twice as long at full speed to get back to the dock going against the current. </span>
<span>(x + 5)/(x - 5) = 2 </span>
<span>x = 15
</span><span>The full speed of the fishing boat is 15 miles per hour.</span>

Answer:
-79.8
Step-by-step explanation:
The change can be found by subracting the ending distance from the beginning distance.
In this case, its 200.6-120.8= 79.8
It is negative because the distance in the end became lower than the beginning distance.
Hope this helps!
