Answer: -4

Reasoning: so first you need to subtract the 7 from the 9 to get -2. Then you square it to get 4 because a negative 2 times -2 is 4. Then you multiply the 4 by the 2 to get 8. You can simplify the -10/5 to -1/2 and multiply that by the 8 to get -8/2 which simplified out to -4.


I hope that helps.

The table below shows the distance d(t) in feet that an object travels in t seconds: t (seconds) d(t) (feet) 1 15 2 60 3 135 4 2
storchak [24]

Answer:


Step-by-step explanation:

Answer:


Option B is correct


The average rate of change of d(t) between 2 second and 4 second is; 90 ft/s


and it represents the average speed of the object between 2 seconds and 4 seconds.


Step-by-step explanation:


Average rate of change of function is defined as the ratio of the difference in the function f(x) as it changes from a to b to the difference between a and b. Then, the average rate of change is denoted as A(x).




As per the given statement, the distance d(t) is in feet and t is the time in second.


To find the average rate of change of d(t) between 2 seconds and 4 seconds.


From the table we have;


at t = 2 , d(2) = 60


and


at t =4 , d(4) = 240.


Then, by the definition of average rate of change ;


=


Simplify:




therefore, the average rate of change of d(t) between 2 second and 4 second is; 90 ft/s and it represents the average speed of the object between 2 seconds and 4 seconds.
