Answer:

Step-by-step explanation:
we know that
The right bisector of the line segment JK is a perpendicular line to the segment JK that pass through the midpoint of segment JK
step 1
Find the midpoint JK
The formula to calculate the midpoint between two points is equal to

we have

substitute the values



step 2
Find the slope JK
The formula to calculate the slope between two points is equal to
we have

substitute
step 3
Find the slope of the line perpendicular to the segment JK
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)

we have
----> slope of segment JK
Find m_2
substitute


step 4
Find the equation for the right bisector of the line segment JK
The equation in point slope form is equal to

we have


substitute

Convert to slope intercept form
isolate the variable y




A and b are legs
a^2+b^2=c^2
lets say
a>b
so
a=13+3b
c=14+3b
a^2+b^2=c^2
(13+3b)^2+b^2=(14+3b)^2
9b^2+78b+169+b^2=9b^2+84b+196
10b^2+78b+169=9b^2+84b+196
minus 9b^2 both sides
b^2+78b+169=84b+196
minus 84b both sides
b^2-6b+169=196
minus 196 both sides
b^2-6b-27=0
factor
(b+3)(b-9)=0
set to zero
b+3=0
b=-3, false, dimentions cannot be negative
b-9=0
b=9
shorter leg is 9
a=13+3b
a=13+3(9)
a=13+27
a=40
c=14+3b
c=14+27
c=41
side legnths are
9in, 40in, 41in
Mean basically means average/ all the numbers added together divided by the amount of numbers given to us
So all the numbers added up will equal to 51 (-5+-3+-1+6+6+9+9+10+10+10) now divide that by the number of of numbers me given to us which is 10 so
51/10= 5.1
Mean=5.1
Answer
yes it is 1.25/1
Step-by-step explanation:
divide 3.75 by 3
Answer:
6
because when you subtract 6 from 6 you get 0
6 - 6 = 0
