Answer: (3)The average change in temperature each day is 5 degrees. (4) The average number of points relatives to their opponents is 8. (5)The average yearly drop in enrollment is 12. (6) It will take 11 min.
Explanation:
The Formula to find the average is,
(3)
It is given that Total dropped temperature in 7 days is 35.
Since total change in temperature is 35 and number of days is 7.
Therefore, the average change in temperature each day is 5 degrees.
(4)
The teams lost by total of 48 points in 6 matches.
Since total points is 48 and number of matches is 6.
Therefore, the average number of points relatives to their opponents is 8.
(5)
The school dropped by 60 students over 5 years.
The total number of dropped students is 60 and the number of years is 5.
Therefore, the average yearly drop in enrollment is 12.
(6)
The submarine descends at the rate of 60 feet per min. The total depth is 660.
Therefore, the submarine will descend 660 feet in 11 min.
Answer:
(-1.92, 1.08)
Step-by-step explanation:
The <em>incenter</em> is the center of the largest circle that can be inscribed in the triangle. That circle is called the <em>incircle</em>. The incenter is at the point of intersection of the angle bisectors. For a right triangle, the <em>inradius</em> (the radius of the incircle), is found from a simple formula:
r = (a + b - c)/2 . . . . . where c is the hypotenuse, and a and b are the legs
In your triangle, the inradius is ...
r = (5 + 3 -√(5² +3²))/2 = 4 -√8.5 ≈ 1.08452
Among other things, this means the coordinates of the incenter are about (1.08, 1.08) from the right angle vertex, so are about ...
incenter ≈ (-1.92, 1.08)
The midpoint of a line segment is simply the average of the coordinates.
If you have endpoints (x1,y1) and (x2,y2) the midpoint is:
mp=((x1+x2)/2, (y1+y2)/2)
