54/3= 18
18•2=36
36+18=54
The shortest piece is 18in
Answer is -7
=============================================
Work Shown:
s_n = a_1*(1-r^n)/(1-r)
s_6 = a_1*(1-r^6)/(1-r)
s_6 = x*(1-(-3)^6)/(1-(-3))
s_6 = x*(1-729)/(1+3)
s_6 = x*(-728)/4
s_6 = x*(-182)
s_6 = -182x
-182x = s_6
-182x = 1274
x = 1274/(-182)
x = -7 is the first term of the geometric sequence
------------
Extra info:
The first six terms of this geometric sequence is
-7, 21, -63, 189, -567, 1701
those six terms add to
-7+21+(-63)+189+(-567)+1701 = 1274
which verifies we have the right answer.
It's B=30 degrees
since a and b are equal to number 2, they are the same value. Because A is 30 degrees, B is 30 degrees too.
Answer:
B if not sorry
Step-by-step explanation:
Hello there!
Your answer would have to be C. where the function crosses the y-axis
Hope This Helps!
