Answer:
Up
Step-by-step explanation:
Here the easy rules to remember the orientation of the parabolas are
a) If x is squared it opens up or down. And its coefficient of {
Hence in our equation of parabola
x is squared and its coefficient is positive , hence it opens up towards positive y axis.
Answer:
the triangle is not right angled traingle
Step-by-step explanation:
For a right angle triangle
+
=
where a is the base , b is the height and c is the hypotenuse
taking a= 6 b = 14 and c = 15
hence +
=
36+196 = 232 which is not equal to 225
therefore the triangle is not right angled traingle
