Step-by-step explanation:
a + a r + a r^2 + a r^3 + a r^4 + a r^5 + ar^6
a r^2 = 108
a r^5 =-32
r^5/r^2 = - 32/108 = -8/27
r^3 = -2^3/3^3 =
r = - 2/3

Answer:
Lucy paid the least amount of money and she paid $770
Step-by-step explanation:

920 x .15= $782
for lucy you do:
1000 x .15= $150
150 + 80= $230
1000-230= $770
Formula to find the arc length is:

Where, s= arc length,
r = radius of the circle
\theta = central angle in degrees.
According to the given problem, \theta= 150 and r =2.4.
So, first step is to plug in these values in the above formula to get the arc length.

=


So, arc length is
.
