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
The equation stated gives the answer of 270.4375
Answer:
4x49=196 which is equivilant to 14x14
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
so plug in x into the function h(x) to get h(x)
h(x) means x in terms of h, you can also think of this as "y"
so at x = -1, y = -2
so,
h(-1) = -2
