What is the slope of a line perpendicular to the line through the points (-1,6) and (3,-4) ?
A. m=-5/2
B. m=-1
C. m=-2/5
D. m=2/5
The slope of the line passing through two points (-1, 6) and (3, -4) is Option A ( m = [tex]\frac{-5}{2}[/tex] )
It is given that, the line is passing through two points (-1, 6) and (3, -4)
Slope is the measurement of the level of steepness of the line or it is a line's steepness determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).
The formula to find the slope of the line passing through two points is given by
m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
We need to find the slope of the line passing through both points
where y1 = 6, y2 = -4, x1 = -1, x2 = 3
Putting values in the formula to find the slope of the line
we get,
m = [tex]\frac{-4 - 6}{[3 -(-1)]}[/tex]
m = [tex]\frac{-10}{4}[/tex]
m = [tex]\frac{-5}{2}[/tex]
Hence The slope of the line passing through two points (-1, 6) and (3, -4) is m = [tex]\frac{-5}{2}[/tex]

In this problem, you will investigate the relationships among three points of concurrency in a triangle.
c. Draw a right triangle and find the circumcenter, centroid, and orthocenter.
Construct the centroid (medians), circumcenter (perpendicular bisectors), and orthocenter of a right triangle (altitudes).
What points of concurrency are always inside the triangle?The three angle bisectors of a triangle are concurrent in a point equidistant from its sides. The incenter of a triangle is the point at which the triangle's angle bisectors intersect. The incenter is always inside the triangle.
The point where the three perpendicular bisectors meet is the circumcenter of a triangle. It is the circumcenter of the circle encircling the triangle, equidistant from the triangle's three vertices.
The incenter exists crucial for angle bisectors; the orthocenter is important for perpendicular bisectors; the circumcenter is important for altitudes; and the centroid is important for medians.

An athlete preparing for a marathon runs 21.3miles .how many kilometers did they run?
An athlete preparing for a marathon runs 21.3 miles then the athlete will run 34.27903 kilometer.
What is kilometer?The kilometer (spelled kilometer in American English) is just a metric unit of length equivalent to one thousand meters.
Since there are 1.6 kilometers in a mile, multiply the number of miles by 1.6 to convert them to kilometers. Because 20 × 1.6 = 32 kilometers, 20 miles is equivalent to 32 kilometers. The more precise method would yield a conversion of 20 miles to kilometers of 32.1868.
Conversion of mile into kilometer.
It is known that, 1 mile = 1.60 kilometer.
Then, 21.3 mile = 1.60 × 21.3 = 34.08 kilometer.
An athlete training for a marathon will cover 34.27903 kilometers if they run 21.3 miles.
Therefore, the athlete will run 34.27903 kilometer.
