Question:
Which of the following represents two lines that are coplanar and do not intersect?
A. Perpendicular
B. Skew
C. Parallel
D. Intersecting
Answer:
Two lines that are co -planar and do not intersect is Parallel.
Step-by-step explanation:
Two lines are said to be parallel if they lie in the same plane, and are the same distance apart over their entire length.Each line has many parallels. Any line that has the same slope as the original will never intersect with it. Hence Parallel Lines would never cross, even if extended forever. Technically parallel lines are two coplanar which means they share the same plane or they're in the same plane that never intersect
Answer
-sqrt(18)<x<sqrt(18)
Step-by-step explanation:
- Factorise:(x-sqrt(18))(x+sqrt(18))<0
- Critical values:-sqrt18 and sqrt18
- Use number line or graphical method
Answer:
6 + 3y
Step-by-step explanation:
a + b = b + a
Numbers can be added in any order, and you still get the same answer
The function of the trapezoid area is:
A(x)=(B+b)*h/2
Where B and b are the bases and h is the height.
With the given data: h=10 B and b =7 and x (it may vary which one is bigger)
-----------
So that function becomes:
A(x)=(7+x)*10/2
A(x)=(7+x)*5
----------
So if you want the inverse function, you have to operate to find x:
A(x)/5=7+x
A(x)/5-7=x
----------
So the new function is:
x(A)=A/5-7
