Answer:
The different variable in C is 21213316700.
Explanation:
Given value:
Total value = letters + underscore value
Total value = 52 + 1
Total value =53
choice for first character = 53 letters +10 digits
first character = 63
choice for remaining characters
So,
Variable number With one 1 character = 53
Variable number With 2 character = 53 × 63
Variable number With 3 character = 53 × 63²
Variable number With 4 character = 53 × 63³
.
.
.
Variable number With 7 character = 
Total difference variable = 53 + 53 × 63+ 53 × 63²+ 53 × 63³+....+ 
Total difference variable = 53(1 + 63 + 63²+ 63³+ .... + )
Formula:
Total difference variable
Answer:
The wide range of materials used to create the Buk (mask) of the Torres Strait has been interpreted as evidence of the islanders' far-reaching trade networks
C preference for local natural resources
Explanation:
The Buk (mask) aged middle to late 19th century C.E., was located in Australia, Mabuiag Island, Queensland, Torres Strait, which is between Australia and Papua New Guinea with many small mostly uninhabited islands around. Archaeological excavations show people´s arrival at Mabuiag islands around 7,300 years ago, being very dependent on ocean´s products to survival.
Few surviving pieces, made out of local resources materials such as turtle shell, wood, fiber, cassowary feathers, resin and paint, tell us feathers were a throughoutly artistic material used in Oceania
, but turtle shells masks were Torres Strait´s people hand-crafted and unique hallmark to be used during assorted ceremonies.
