The changing speed of a car is modeled by the function S(t) = –4t + 35, where t is time in seconds. Interpret the model. A. The car has an initial speed of 0 units and is speeding up to a speed of 35 units by 4 units per second.
B. The car has an initial speed of 4 units and is speeding up by 35 units per second.
C. The car has an initial speed of 35 units and is slowing down by 4 units per second.
D. The car has an initial speed of 35 units and is speeding up by 4 units per second.

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.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
