The answer is A I believe
None of the answer choices makes any sense. (You should have your teacher show you how to select the correct choice.)
_____
Answers that are closer to the plotted points are ...
... A = -0.9, B = -9/16, C = -0.4, D = -1/16
The attachment shows these points plotted. As you can see, even these values aren't quite right.
Answer:
The second is the answer
Step-by-step explanation:
Answer:
-1 and -6.
Step-by-step explanation:
-1 and -6
-1*-6 = 6
-1 + (-6) = -1-6= -7.
The end of its travel is when S(t)=0 or when it has hit the ground...
-16t^2+25=0 divide equation by -1
16t^2-25, this is a difference of squares which always factors:
(a^2+b^2)=(a+b)(a-b), in this case:
(4t+5)(4t-5)=0, since t>0
t=5/4=1.25, and since it started falling at t=0, its time moving in the air is:
1.25-0=1.25 seconds.
