Please see attached document for the graphs:
The functions with the given graphs can't be solutions of
the differential equation dy dt = et(y − 1)2.
(a) won’t work, since it has negative slope on portions of its solutions. The
slope, e t (y − 1)2 , is a nonnegative function.
(b) won’t work, since it has positive slope at y = 1, where the slope must be flat.
Answer:
AO bisects BAC - Needed
AO is perpendicular to BC - Needed
Point O is the midpoint of BC - Not needed
AO is an altitude - Not needed
Step-by-step explanation:
In ΔAOB,
- <BOA = 90° (since AO is perpendicular to BC )
- <BAO =
<BAC (since AO bisects BAC)
In ΔAOC,
- <COA = 90° (since AO is perpendicular to BC )
- <CAO =
In ΔAOB and ΔAOC,
- <BOA = <COA (since both are 90°)
- <BAO = CAO (since AO bisects BAC)
- AO=AO
So, we can conclude ΔAOB ≅ ΔAOC (<em>ASA property</em>) and hence the base angles <ABO and < ACO of the isosceles triangle ABC are also congruent.
