The circumcenter is found by finding the intersection of at least 2 perpendicular bisector segments.
Find the perpendicular bisector to segment AB. This is the line y = -3.5; the idea is that you find the equation of the horizontal line through the midpoint of AB. The midpoint has a y coordinate of -3.5. This line is shown in red horizontal line in the attached image below.
The midpoint of AC is 2.5, so the perpendicular bisector to AC is x = 2.5 which is shown as the vertical green line in the same diagram.
The red and green lines cross at the location (2.5, -3.5) which is the circumcenter's location. If you were to draw a circle through all three points A, B, & C, then this circle would be centered at (2.5, -3.5)
If point D is the circumcenter, then we know this
AD = BD = CD
basically the distance from the center to any point on the triangle is the same. This is due to the fact that all radii of the same circle are the same length.
<h3>Answer: (2.5, -3.5)</h3>note: 2.5 in fraction form is 5/2 while -3.5 in fraction form is -7/2
Answer:
Each pack of chicken costs $8 and each pack of beef costs $9.24.
Step-by-step explanation:
This question can be solved using a system of equations:
I am going to say that:
x is the cost of each pack of chicken.
y is the cost of each pack of beef.
2 packs of chicken and 3 packs of beef for $42.50.
This means that
5 packs of chicken and 6 packs of beef for $94.25.
This means that
We have to solve the following system:
I will use the addition method, multiplying the first equation by -2, and adding to the second
-4x + 5x - 6y + 6y = -85 + 94.24
x = 9.24.
And
Each pack of chicken costs $8 and each pack of beef costs $9.24.
