One way to locate the vertex is to obtain the coefficients a, b and c from the quadratic and then calculate
-(-16)
x = -b / (2a). Here, x = ---------- = -2
2(-4)
Next, evaluate y at x = -2: y = -4(-2)^2 - 16(-2) - 12 = -16 + 32 - 12
y = 4
the vertex is at (-2,4).
Total amount of grey blocks is 55 so divide that by the amount of columns it’s being divided into. The answers 5.
Answer:
64 because they are vertical angles
Answer:
Step-by-step explanation:
Note that the four input values, {3,4,6,11}, are all unique. Each has exactly one y value associated with it. This is an important criterion when we're deciding whether a relation is a function or not.
Suppose that we added one more input and its associated output:
{3,4,4,6,11}
If it happened that different values of y were associated with the two 4's, then we know immediatel that this relation is not a function.
Answer:
598 meters
