Step-by-step explanation:
The relevant transformations are ...
(x, y) ⇒ (x, -y) . . . . . . reflection across the x-axis
(x, y) ⇒ (-x, y) . . . . . . reflection across the y-axis
__
A) sign of y-coordinate has changed: reflection across the x-axis
B) signs of both coordinates have changed: reflection across both axes

Answer:
8184 vocalists sang in total
Step-by-step explanation:
The number needed is ...
8 + 16 + 32 + 64 + 128 + 256 + 512 + 1024 + 2048 + 4096
You can add these up to get a total of 8184, or you can use the formula for the sum of a geometric series:
Sn = a1(r^n -1)/(r -1) . . . . where a1 is the first term and r is the common ratio
S10 = 8(2^10 -1)/(2 -1) = 8(1024 -1)/1 = 8184
