Base on the diagram you give and the choices where there is two triangle that both have vertexes, lines and segment. By calculating and analyzing the diagram , I conclude that the answer would be D. BD is congruent to RT. I hope i answered your question
By graphing the given equation
<span>r = 4 - 3 sin θ
We find that </span><span>the graph is symmetric about the y-axis
The graph of the given equation is attached below
------------------------------------------------------------------------------
Some information about the given equation:
the given equation is like the form of the </span>
Cardioid
A curve that is somewhat heart shaped. A cardioid can
be drawn by tracing the path of a point on
a circle as the circle
rolls around a fixed circle of the
same radius.
The equation is usually written in polar
coordinates.
Equations of Cardioid:
r = a ± a cos θ (horizontal)
or <span>r = a ± a sin θ (vertical)</span>
Answer:
140
Step-by-step explanation:
S = a*((1 - r^(n+1))/(1-r))
S = 1*((1 - 2^(7+1))/(1-2))
S = 1*((1 - 2^8)/(1-2))
S = 1*((1 - 256)/(1-2))
S = 1*((-255)/(-1))
S = 255
So 1+2+4+8+...+128 = 255
