This would be perpendicular
Answer:
all real numbers
Step-by-step explanation:
the domain will always be all real numbers
Make equal to 0
minus 12from both sides
x^2+10x+13=0
we can't factor so use quadratic formula

Answer:
2/5
Step-by-step explanation:
10/10 = 1 Whole
You need 4/10 to get 1 whole
4/10 is equivalent to 2/5 because when you divide the numerator and denominator by 2 you the 2/5.
Answer:
Probability that the measure of a segment is greater than 3 = 0.6
Step-by-step explanation:
From the given attachment,
AB ≅ BC, AC ≅ CD and AD = 12
Therefore, AC ≅ CD = 
= 6 units
Since AC ≅ CD
AB + BC ≅ CD
2(AB) = 6
AB = 3 units
Now we have measurements of the segments as,
AB = BC = 3 units
AC = CD = 6 units
AD = 12 units
Total number of segments = 5
Length of segments more than 3 = 3
Probability to pick a segment measuring greater than 3,
= 
= 
= 0.6
