Step-by-step explanation:
<u>Circumcenter of a Triangle</u>
The circumcenter is a point where all the tangent lines of the midpoints of the three sides meet.
The coordinates of the vertices of the pool are (3, 3), (11, 3), and (3, −3). Please refer to the image below where the three midpoints are also shown. Since the triangle is right and two of its sides are parallel to the x-axis and the y-axis, the coordinates of the midpoints are very easy to find
Midpoint of (3, 3), (11, 3)=([3+11]/2,[3+3]/2)=(7,3)
Midpoint of (3,3), (3,-3) =([3+3]/2,[3-3]/2)=(3,0)
The intersection of both lines (shown in red) is the point (7,0) which is also the midpoint of (3,-3), (11,3). Thus this point is where all the midpoints meet.
Answer: C. (7, 0)
We have been given an equation . We are asked to find the decimal coefficient of the equation.
We know that coefficient of an equation is the number multiplied by variable.
We can see that and 1.5 are constants for our given equation.
We can see that variable of our given equation is . We can also see that
is being multiplied by 0.5, therefore, 0.5 would be the decimal coefficient of our given equation.
