<span>Based on the lengths given, 6 cm, 10 cm and 12 cm, the classification that best describes the triangle is that "It is a Scalene triangle." A scalene triangle is a type of triangle whose sides are not of the same length. </span>
Answer:
C. Centroid
Step-by-step explanation:
The circumcenter is the center of a triangle's circumcircle (circumscribed circle over triangle). It can be found as the intersection of the perpendicular bisectors.
The incenter is the center of the incircle (inscribed circle into a triangle) of a triangle. The incenter can be constructed as the intersection of angle bisectors.
Centroid is the point where the three medians of the triangle intersect.
The intersection of the three altitudes of a triangle is called the orthocenter.
Since three medians intersect at point which divides each median into 2:1 ratio, the answer is centroid.
Answer:

Step-by-step explanation:
use y = mx + b
slope(m) =
y-intercept(b) = 3
so,

Yes you have the correct answers for each of the four problems. Nice work.
For anyone curious,
rd = removable discontinuity
id = infinite discontinuity
c = continuous
