Answer:
Option B:
Step-by-step explanation:
The parabola has its concavity downwards, so we need a function in the model:
With a negative value of 'a'
The vertex is (0,0), so we have that:
The x-coordinate of the vertex is given by the equation:
So we have a function in the model:
With a < 0
The only option with this format is B:
4/5 -3/7=
28/35 -15/35
=13/35
Answer:
1.2
Step-by-step explanation:
setup: 6/5 = 1.2
B: BC
The longest side of a triangle is the side that is across from the largest angle. Angle A is the largest angle and is across from side BC, so side BC is the longest side of triangle ABC
