The vertex is the highest point on a downward-opening parabola or the lowest point on an upward-opening parabola.
Answer:
√89
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(9 - 1)² + [-6 - (-1)]²
√(8)² + (-5)²
√64 + 25
√89
C, because 7 divided, or over nine, is 7/9
Hope this helps!
The answer is the first one:
bc its not growing by a (-)1/2 and the 3rd one just doesnt make sense
A triangles three angles always sum up to 180 degrees. We must find angle B.
We already have angle A and C, so it's quite simple.
Angle A is 28*, and angle C is 36*
We add these two together
28 + 36 = 64
Now we subtract
180 - 64 = 116
Angle B = 116*
Hope this helps you! (:
