The height, in meters, of a coin dropped from a tall building is modeled by the equation d(t) = 4.9t2 where d equals the distance traveled at time t seconds and t equals the time in seconds. What does the average rate of change of d(t) from t = 3 to t = 6 represent? The coin travels an average distance of 44.1 meters from 3 seconds to 6 seconds. The coin falls down with an average speed of 14.7 meters per second from 3 seconds to 6 seconds. The coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.
The coin travels an average distance of 14.7 meter
@ooops
if plugging 3 and 6 to the equation, what do you have for d(3) and d(6)?
44.1 for d(3)
d(6)=176.4
@ooops you there?
something is wrong !! I posted, I saw my comment and then it disappeared. Magic!!
:P hmm
\(\dfrac{d(6)-d(3)}{6-3}\)
maybe you typoed and some program marked ity as innapropriate and it s=dissapeared
so d3/3
That's the average change of distance in 3 seconds
okay
so? the answer is?
A?
nope, the last one, because distance/ time = velocity
okay thx
no isnt direction/time velocity?
i thought d/t was speed
nope
the entire D The coin travels an average distance of 14.7 meters is per second from 3 seconds to 6 seconds.
@OOOPS
how about this option? The coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.
your d(t) is the equation of distance, not velocity
still not get?
i get it im checkin now
wait i just clicked wrong my first try
the equation is -b/2a right?
What are you talking about? -b/2a is the last question, not this. This question is about distance and velocity. If they said so, click A. I don't know why but just 2 of them are correct. To me, it's the last one. Maybe, I am wrong
ik im redoing the assesment and i got the same question different equations i was jsut making sure
i misclicked the first on i think the last 1 is right
thx i have one morwe Q
thx @ooops
@OOOPS what was the anwser to the first question a b or c?
@OOOPS
what??? this post was posted 3 months ago, right? how it still works???
@OOOPS with the school we do, they circulate questions. Thanks for the help you didnt mean to give XD you helped check my work
