Answer:
The car has an initial speed of 35 units and is slowing down by 4 units per second.
Step-by-step explanation:
The changing speed of a car is modeled by the function :

t is time in seconds
Initial speed means at t = 0
s(0) = 35 units
Here the change in speed is negative, it means that the car is slowing down by this rate.
So, the correct answer is : The car has an initial speed of 35 units and is slowing down by 4 units per second.
The length of wire to be purchased will be found as follows:
c²=a²+b²
c²=18²+24²
c²=900
c=√900
c=30 ft
Thus the length of the wire will be:
30+4+4
=38 ft
