Answer:
4
Step-by-step explanation:
x^2/ y^4
Let x=8 and y=2
8^2 / 2^4
PEMDAS says powers first
64 / 16
Divide next
4
Answer:
Step-by-step explanation:
Mode is the number that appears most often in a set, so for this one the mode would be 3 since it appears the most often
The circumcenter<span> of a </span>triangle<span> is the point where the perpendicular bisectors of the sides intersect.
from the graph, we can see that the perpendicular bisector of BC is the y axis, x=0, the perpendicular bisector of AC is y=-3, so the circumcenter is (0,-3)</span>
Step-by-step explanation:
Intersecting secant angles theorem: The angle between two secants is half the difference of the intersected arcs.
52 = ½ (x − 38)
x = 142
Arc angles add up to 360.
360 = 80 + 38 + z + x
z = 100
Tangent-chord theorem: The angle between a tangent and a chord is half the intercepted arc angle.
y = x/2
y = 71
