Two lines are:

Parallel if they don't intersect and lie on the same plane
Intersecting if...well, they intersect at one point
Skew if they don't intersect and they lie on two different planes

So, we have:

AB and BC intersect at point B
AE and BF don't intersect, but both lie on the plane AEFB
EF and AD don't intersect and don't lie on a common plane
ABC and ABF intersect on segment AB
AED and BFC are parallel (they're both perpendicular to plane ABC)

What are some ways to remember postulates in geometry?

I took five years before and it was hard for me to remember the postualates. I found it helpful to practice proving problems that involved the postualate. Some postualates like SAS are just abbreviations. SAS- Side-Angle-Side

A ball is thrown into the air with an upward velocity of 36 ft/s. Its height h in feet after t seconds is given by the function

FinnZ [79.3K]

Answer:

The ball reaches a height of 29.25 ft after 1.125 seconds

Step-by-step explanation:

The maximum height of a parabola can always be found by looking for the vertex. You can find the x value (or in this case the t value) of a vertex by using -b/2a in which a is the coefficient of x^2 and b is the coefficient of x.

-b/2a

-(36)/2(-16)

-36/-32

1.125 seconds

Now to find the height, we input that value in for t

h = -16t^2 + 36t + 9

h = -16(1.125)^2 + 26(1.125) + 9

29.25 feet
