I think the your princetoneclub.org would certainly be B) lines that meet at a 90 degree angle. This lines need to intersect, and they have actually slopes that are opposite reciprocals when contrasted to each other.

You are watching: Which of the following best describes perpendicular lines

Lines that satisfy as a 90° angle....For currently to it is in perpendicular, the slopes the the lines have to be an unfavorable reciprocals that one another, mathematically:m1*m2=-1Note that \"slope\" is velocity or adjust in y separated by change in x. Using any type of value because that m1, to speak 3 together an example.m1=3, climate m2=-1/3tanα=dy/dx=m soThen if we usage the arctan duty we deserve to see the angle of the lines, ieα=arctan3, ß=arctan(-1/3)α≈71.56°, ß≈-18.44α-ß=90°

42p^4 + 9p^3q^2 -18p^2q^2 = p^2 (42p^2 + 9pq^2 - 18q^2)

Step-by-step explanation:

To princetoneclub.org this, we just look for the term that is typical to all

Looking at the given expression, we have the right to see the the term we are trying to find is p^2

Thus, we have that;

42p^4 + 9p^3q^2 -18p^2q^2 = p^2 (42p^2 + 9pq^2 - 18q^2)

When us multiply the term external the bracket with each the the terms inside, us get back the initial term

-9, -8, - 3, 0, 3, 8

Step-by-step explanation:

Given the number :

0,-3,3,-8,8,-9

Higher number with an adverse sign space lowest :

Using the setup pattern on a number line from left to right ;

-9, -8, - 3, 0, 3, 8

A inspection asks teachers and also students whether they would prefer the new school mascot to be a shark or a moose. This table reflects the

princetoneclub.org:

The correct statement is (D).

Step-by-step explanation:

Compute the probabilities for the data provided:

Probability college student preferring sharks: Probability teacher preferring sharks: Probability student preferring moose: Probability teachers preferring moose: From the over computations it can be concluded that:

Shark is more popular v students.Moose is equally famous with students and teachers.

Thus, the exactly statement is (D).
