Hey guys I'm Mj and I am going to tell you guys some vocabulary to understand our project.
First one is parabola a symmetrical open plane and then the next one is focus a point inside
the parabola the directrix is a line outside the parabola that is perpendicular to the
axis of symmetry the vertex is the top or apex and the standard equation for the parabola
is ax+bx=c. Hi My name is Sylvia and I gonna explain how everything applies to our dish
and how we got our equation. the parabola is the satellite dish the focus is how long
the chopstick needs to be for optimal cooking the vertex has to be at 0,0 or the origin
in order to determine how wide the satellite will be. the directrix allows the vertex and
focus to be perpendicular to our satellite. UHHMM. We got our equation by taking the value
of a to be a round number with out decimals. Since 16 is divisible by four it seemed logical
to change it to that since it was close to our original equation. Hi my name is Taylor
and to determine the location of the focus, we used our calculator to see which one was
the best if we were to make it into a satellite some problems we encountered was that we initially
designed a 1/15 parabola but chose not to because we wanted are a value to equal a round
number rather than a decimal materials and the cost are hyahhh marshmallows one pack
was 99 cents card board two strips previously owned chopstick previously owned tinfoil previously
owned duck tape previously owned textbook previously owned MATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATHMATH
Hi Im Verna and Im talking about the special contributions that our group mates did Shiva
contributed to the written report he helped solve the equation for teh dish he constructed
the interior and exterior of the dish was responsible for taking pictures and owned
the tinfoil for making the satellite. Mj was responsible for the written report drew an
exact copy of the parabola helped solve the equation for the dish and designed the interior
and exterior of the dish. Taylor halped solve the parabola equation contributed to the written
report constructed the design of the satellite designed the interior and exterior of the
satellite brought marshmallows for testing the satellite brought copper wire for the
satellite I helped in writing the written report helped design the exterior and Sylvia
helped design the interior and exterior of the dish and helped the written reprot and
we all helped in making the video YAYAYAYAYYAYAYAYAYYAYAYYAYAYYAYAYAYy
