Step-by-step explanation:
3x+5=44
3x=44-5
3x=39
x=39÷3
x=13
It's

because this choice made the most since.

Answer:
5000
Step-by-step explanation:
In vertex form, the cost function is ...
C(x) = 3(x² -10x) +175 = 3(x² -10x +25) +175 -3(25)
C(x) = 3(x -5)² +100
The vertex is at x=5, so the cost function will be minimized when 5000 speed boats are produced.
It’s 40 degrees since the bisect of an angle is just half of the original angle.
