Answer:
the value of angle W = 81° and x = 35°
Step-by-step explanation:
the explanation is in the attached picture
The a and b determine how big or small the shape of the conic section is.
<span>For the different conic sections given through the equations </span>
<span>Circle: x^2/a^2 + y^2/a^2=1 </span>
<span>Ellipse: x^2/b^2+y^2/a^2 = 1 </span>
<span>Hyperbola: x^2/a^2 - y^2/b^2 = 1 </span>
<span>When trying to isolate cos and sin from those equations to get cos^2t + sin^2 t = 1 you can determine the conic section when substituting cos t = x/a and sint = y/b into cos^2t+sin^2t square it and then refer to the conic section equations to determine the conic section. x defines the major axis and y is the minor axis. a and b provide the coordinate pairs</span>
We have
The rational root theorem suggests that other possible roots may be -6, 6, -3, 3, -2, 2, -1, and 1. It turns out that 
is a root, since 
, so 
is also a factor and we have
Finally, we can factorize the remaining quotient easily:
so the other factors are , 
, and 
.
1) a = tickets in advance goal = 2000
d =tickets at door
6a +8d = 2000
6(142)+8d =2000
852+8d=2000
8d=2000-852
8d=1148
d=1148/8
d=143.5
round up d=144 need to sell 144 tickets at door
