Answer:
All the none-zero digits given should be included when written in scientific notation. But also any trailing zeros written after non-zero digits should also be included.
For example in 0.00900 the 900 is significant because the person who included the trailing zeros is saying look I measured this far and these zeros are significant.
Answer:
4%
Step-by-step explanation:

A = final amount
P = initial amount
r = interest rate per time period
n = number of times compounded per time period
t = number of time period
A = 3932.82
r = what we want to find
n = 2
t = 6

divide both sides by 3101 to isolate the exponent and its parts

put both sides to the power of (1/12) to help isolate the variable

subtract 1 from both sides to isolate the variable and its coefficient

multiply both sides by 2 to get r

r ≈ 0.04 = 4%
9514 1404 393
Answer:
64 -16π square units
Step-by-step explanation:
The area of the square is ...
A = (8 units)^2 = 64 units^2
The area of the circle is ...
A = πr^2 = π(4 units)^2 = 16π units^2
The shaded area is the difference:
shaded area = (64 -16π) units^2.
