Answer:
200√2 square units
Step-by-step explanation:
The area of a regular polygon with n sides and radius r is given by the formula ...
A = (n/2)r²·sin(360°/n)
Here, we have n=8 and r=10, so the area is ...
A = (8/2)(10²)sin(360°/8) = 4·100·√2/2
A = 200√2 . . . square units

What is the answer to -12= x -5?
Answers
Answer:
Step-by-step explanation:
-12 = x-5
5-12 = x -5 + 5
-7 = x
there you go :)
Answer:
x = -7
Step-by-step explanation:
1. Write the equation.
-12 = x - 5
2. Since 5 is negative and we want to leave x by itself, add 5 to both sides. Adding 5 with cancel out the -5.
-12 +5 = x -5 +5
3. When you add +5 to -12, the equation you are left with will be:
-7 = x

Use the properties of logarithms to determine the value of logb 1. Explain your reasoning.
Answers
Answer:
[tex]log_b 1 = 0[/tex]
Step-by-step explanation:
Given
[tex]log_b 1[/tex]
Required
Solve
[tex]log_b 1[/tex]
Express 1 as [tex]b^0[/tex]
[tex]log_b 1 = log_b b^0[/tex]
Apply power rule of logarithms
[tex]log_b 1 = 0 * log_b b[/tex]
Multiply by 0
[tex]log_b 1 = 0[/tex]
Answer:
logb 1 = 0
Step-by-step explanation:
Suppose that logb 1 = x.
Using the definition of a logarithm, bx = 1.
The only way a number that’s not equal to 1 can be raised to a power and equal 1 is if the exponent is 0. So, x = 0.
Therefore, logb 1 = 0.
