Answer:
A
Step-by-step explanation:
a(7+2)
first we have to distribute
A times 7 is 7a
2 times a is 2a
and considering that both 7a and 2a are like terms they can be added
therefor, 7a+2a=9a
You need to calculate the two zeros of the function. The first zero is the "start", the second zero is the "end" of the trajectory.
Well...
0 = x(-16x+80)
First zero is x=0 (the start of trajectory)
Second zero:
-16x+80=0.... x=5! (The end of the trajectory!)
Good luck!
