Answer:
A = 240 units²
Step-by-step explanation:
the area (A) of a regular polygon is
A =
pa ( p is the perimeter and a the apothem )
here p = 8 × 6 = 48 ( an octagon has 8 sides ) and a = 10 , then
A =
× 48 × 10 = 24 × 10 = 240 units²
4•1\2=1/16
I don’t know the equation but you can just change it around a little
Answer:
Exponentials and logarithms are inverses of each other.
Step-by-step explanation:
Exponentials and logarithms are inverses of each other.
For logarithmic function:
Domain =
, Range = 
Vertical asymptote is y - axis.
x - intercept is (1,0)
For exponential function:
Domain =
, Range = 
Horizontal asymptote is x - axis.
y- intercept is (0,1)
Both exponential and logarithmic functions are increasing.
For example:
Solve: 


Answer: is this correct
Step-by-step explanation:
Consecutive odd or even integers are of the form x, x+2.
So we have x(x+2) = 63, where Diane's age = x.
x²+2x = 63.
x² + 2x - 63 = 0
(x + 9)(x - 7) = 0
x = -9, or 7.
Since -9 is awfully young, we rule it out and say Diane's age is 7, and her sister is 9.
