Answer:
C. government
Step-by-step explanation:
The coordinates of the vertex of the graph are (-2, -9).
The quadratic function is described by the standard equation The graph of a quadratic function is called a parabola.
We have the quadratic function
Finding the minimum value is as follows:
Therefore, the coordinates of the vertex of the graph are (h, k), i.e.,
Other components:
Keywords: the axis of symmetry, for a function, f(x) = x² + 4x − 5, x = −2, which is the graph of f(x) = (x - 1)(x + 4), what, the coordinates of the vertex of the graph, the x-intercept, quadratic function, a standard equation, the y-intercept, parabola, upward, the minimum value
Based on the calculations, the coordinates of the vertex(h, k) of this graph are equal to (-2, -9).
In Mathematics, the standard form of a quadratic equation is given by;
ax² + bx + c = 0
Note: The graph of any quadratic function is known as a parabola.
From the given quadratic function, we have:
f(x) = x² + 4x - 5
For its coefficients, we have:
Next, we would determine the coordinates of the vertex of this graph:
x = h = -b/2a
h = -4/2(1)
h = -4/2
h = -2.
Also, we can deduce that the parabola of this graph opens upward because "a" is greater than zero (0), which produces a vertex that is a minimum:
f(h) = k
f(-2) = k = (-2)² + 4(-2) - 5
f(-2) = k = 4 - 8 - 5
k = -9.
Vertex (h, k) = (-2, -9).

b.cross-pollination, by using parents that had different traits
c.self-pollination, by using one parent
d.random pollination, by using both identical- and different-trait matings
we know that
Gregor Mendal used a process of cross-pollination,by using parents that had different traits in his experiment with pea plants. He was studying the difference between tall and short pea plants, and how genes were expressed differently between the two, so this method of cross-pollination was vital in order to accurately recreate how this process would happen within nature.
therefore
the answer is the option
b.cross-pollination, by using parents that had different traits
circle's radius?
Answer:
Step-by-step explanation:
x²+y² =(Radius)²
x²+y² =10². So the radius is 10
Answer:
radius = 10
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
x² + y² = 100 ← is in this form
with r² = 100 ( take the square root of both sides )
r = = 10
B.(x + 22)2 – 121
C.(x + 7)2 – 47
D.(x – 15)2 + 94
