Answer:A vertex (or node) of a graph is one of the objects that are connected together. The connections between the vertices are called edges or links. A graph with 10 vertices (or nodes) and 11 edges (links).
Step-by-step explanation: (The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.
Answer: 5
Step-by-step explanation:
Range = highest value - lowest value
The highest value from the data set given = 1
The lowest value = -4
Therefore :
Range = 1 - (-4)
Range = 1 + 4
Range = 5
This is how the calculation is done
1/2 = 24/x
x = 48
It's 180-50-50=180-100=80°
Answer:
b is the angle being measured while a is the angle at a point with b
Step-by-step explanation:
The only time we use 360 for calculating an angle is when the two angles are at a point as both of them assuming a and b sum up to 360°.
Therefore a + b = 360
and if b is being measured, b = 360 -a
