Answer:
12
Step-by-step explanation:
The area of a triangle is
A = 1/2 b *h
The base is 6 units (from -2 to 4)
The height is 4 units ( from 1 to 5)
A = 1/2 6*4
= 1/2 (24)
= 12 units^2
Answer:
5-3í
Step-by-step explanation:
Because the root of nine is three, equaling 5-3í
The equation of a parabola in vertex form, is:
Where <em>(h,k)</em> are the coordinates of the vertex.
From the given graph, notice that the coordinates of the vertex are:
The roots are the values of <em>x</em> where the graph crosses the x-axis. In this case, the graph crosses the x-axis at the points <em>(4,0)</em> and <em>(6,0).</em> Then, the roots are:
Substitute the values of the vertex into the equation of the parabola in vertex form:
To find the value of <em>a</em>, substitute <em>(x,y)=(4,0)</em>:
Therefore, the equation of the parabola is:
