Answer:
The answer is A) 1.
Step-by-step explanation: They only cross once
I'm assuming you meant to write 8^(-2) or
where the -2 is the exponent over the 8.
If my assumption is correct, then we use the rule 
So,

<h3>Answer: Choice D. 1/64</h3>
If you mean 1/3 the answer is -15.5
1/3(-32.48-14.02) = 1/3(-46.5) = (-15.5)
The answer to your question is
f(x) =x(x+1)^2 (x-1)
Solution:
Two trains are moving in opposite direction with Speed 40 kmph and 60 kmph. Make train B stationary and then take the Speed of train A relative to the train B. So relative Speed of train A = 40 + 60 = 100 kmph. Before it crashes into the stationary train B it has to travel a Distance of 200 m which it will do in (0.2/100 ) hours. During this duration, the average Speed of bird has been 10 kmph i.e. before the crash total Distance covered by the bird = 0.2 * 10/100 km = 20 meters.
Hope it helps
