Do you mean ^2? cause if so... B don't really need crit points to solve, the parabola has a positive slope before x =2
Answer:
and 
and b=
Step-by-step explanation:
We are given that a quadratic equation

We have to solve the equation by completing square and find the value of b.






and 

And 
Therefore,
and 
and b=
Step-by-step explanation:
b+133=180
b=180-133
b=47
a+71+40=180
a+111=180
a=180-111
a=69
c+64=180
c=180-64
c=116
140=d+47
140-47=d
d=93
e+47+47=180
e+94=180
e=180-94
e=86
Answer:
3
Step-by-step explanation: If they are parallel, the lines will always run the same distance apart and never intersect. If the slopes are different, they will intersect at some point
19750 * 0.8 = 15800
15800 / 26 = 607.69
Answer is A
