The measure of angle 2 is 129 degrees
3.5 is rounded to the nearest tenth.
I hope this helps you
x^2+13x+22=0
(x+11)(x+2)=0
x= -11
x= -2
The slope is 10
since it doesn't say anything after the 10x, the y-intercept is at (0, 0)
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!
