Question

Write a paragraph describing a pyramid based on the following criteria:

Definition
How many bases does it have?
How many lateral faces does it have?
What is the shape of a cross section parallel to the base?
What is the shape of a cross section perpendicular to the base?
How do you find the surface area?
How do you find the volume?
@TraciBonita

Answer 1

A pyramid has 4 faces
It has 5 lateral faces
The volume: V=lwh\3
A=lw+l(w
2)2+h2+w(l
2)2+h2

Answer 2

a monumental structure with a square or triangular base and sloping sides that meet in a point at the top

Answer 3

That's the definition of a pyramid dear.

Answer 4

right im trying to find 2 more

Answer 5

help @TRavi14 @TraciBonita

Answer 6

@1<3mybaby
Which question do you need help with?

Answer 7

Cross sections perpendicular to the base will be triangles

Answer 8

Cross sections parallel to the base will be hexagons

Answer 9

hmmm find 2 more pyramids?

Answer 10

there then, 3 pyramids =)

Answer 11

think about them this way

you grab a regular polygon
and stick strings on all of its vertex points

then grab the strings and pull them up so that they all meet up above

so the pyramid can have any regular, ( or irregular ), polygon as its base
what makes it a pyramid is that all of its vertex meet at one common point

Answer 18

Generally just use u-substitution to find the initial state of a qubit before it is observed in a plus/minus basis then use Grover's Algorithm to search through a lattice of N-indexes. After that, you should end up with a multi-dimensional figure. Just find the partial derivatives. Should allow you to draw a contour plot easily.

Answer 19

i just want the cross sections

Answer 20

Strong acid and weak base results in a pH under 7.
Strong base and weak base results in a lot of base, but it's diluted, so somewhere between the two pH's.

I assume you means a strong base and weak acid for the second one, so I'll answer that too.
Strong base and weak acid results in a pH over 7.
weak of both results in a neutral solution with a pH near 7.

If you titrated them until all the acid and base is used, it always ends up near 7. However, weak acids and bases also result in strong conjugates. So if you have a weak acid, when it is fully titrated, you end up having a relatively strong conjugate base. That's why it ends up being slightly basic. The same thing happens with weak bases.

Answer 21

Oh! In that case, just use Dirac notation to explain the quantum system.

Answer 22

Damnit @iPwnBunnies... do you remember how to set my limit to 0 by ;)

gtg ill be on tomorrow

Answer 24

Thank you everyone for the help BUT! I was just re-reading lessons and I figured most of it out AND THANK YOU @TraciBonita @taylor12344 @happytales YOU ALL HELPED TONS!
