Identify the coefficient and the exponent for each term of 8x4 – 2x.
1 answer:
Given:
The expression is:
To find:
The coefficient and the exponent for each term of the given expression.
Solution:
Coefficients: In the product of s number and a variable, the number is coefficient of the variable.
Exponent: The number in the power is called exponent.
We have,
Here, the terms are .
For the term , the coefficient is 8 and the exponent is 4.
For the term , the coefficient is -2 and the exponent is 1.
Therefore, the coefficients are 8 and -2, and the exponent are 4 and 1.

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
