(a). The element a₂₁ is the number of boys enrolled in Lacrosse.
(b). The address is a₁₂.
(c). [196 174]
[136 169]
[214 242]
(d). The matrix represents the number of boys and girls from towns A and B enrolled in different sports classes.
(e). 1.125 A = [108 90 ]
[72 99 ]
[117 135]<span />
90 degree
or right angle
Hope this helps <span />
The discriminant is b^2 -4ac
a = 1
b = -2
c = 4
discriminant = 4 -4 * 1 * 4 =
4 -16 =
-12
I get MINUS 12 as the answer but that isn't one of the choices.
Unsure of what you are asking!
But if the issue here is how to define a line segment, write what you do know and then reconsider "undefined terms."
A line segment is a straight line that connects a given starting point and given ending point.
If you consider a circle of radius 3 units, the radius can be thought of as the line segment connecting the center of the circle to any point on the circumference of the circle.
If the center of a given circle is at C(0,0) and a point on the circumference is given by R(3sqrt(2),3sqrt(2)), then AC is the line segment joining these two points. This line segment has length 3 and is in the first quadrant, with coordinates x=3sqrt(2) and y=3sqrt(2) describing the end point of the segment.
