Answer:
66 feet
Step-by-step explanation:
Mayra wants to place tiles on the edge of pool, i.e, on the circumference of the circular part
so the length required will be ,2πr
radius=21/2 feet=10.5feet
now req lenght = (2π10.5)=66 (feet)
Answer: 2 decimal digits
Step-by-step explanation:
When multiplying decimals, placement of the decimal point is very important. Since there is one decimal digit in each factor, there must be two decimal digits in the product. This is because tenths x tenths = hundredths
Hope this helps and good luck! :)

Answer:
0, for q ≠ 0 and q ≠ 1
Step-by-step explanation:
Assuming q ≠ 0, you want to find the value of x such that ...
q^x = 1
This is solved using logarithms.
__
x·log(q) = log(1) = 0
The zero product rule tells us this will have two solutions:
x = 0
log(q) = 0 ⇒ q = 1
If q is not 0 or 1, then its value is 1 when raised to the 0 power. If q is 1, then its value will be 1 when raised to <em>any</em> power.
_____
<em>Additional comment</em>
The applicable rule of logarithms is ...
log(a^b) = b·log(a)
Subtract the numbers
Factor out 4 from the expression
When there is a - in front of an expression in parentheses, change the sign of each term in the expression to -
- <em>Thus, Options A and F are correct!!~</em>
