You can calculate the area of the whole pizza according to the formula: S=1/2*π*r². And the area of 8 piece is 1/8S while the area of 12 piece is 1/12S. The answer should be 1/8S-1/12S=4/3π.
1. 8x=24 x=3
2 6x - 12 =12. x= 4
3. -4x+30=-14 x=11
Hope these helps!! I checked the answers and they were all right so dot worry :)
For the given logarithmic function, we have:
domain: (4, ∞).
range: (-∞, ∞).
<h3>
How to determine the domain and range of the function?</h3>
For a function y = f(x), the domain is the set of the possible input values, and the range is the set of the possible output values.
Here we have the function:
f(x) = log(x - 4) - 3
First, we know that the range of logarithmic functions is the set of all real numbers.
We also know that the argument of logarithmic functions can only be larger than zero.
So the domain is defined by x > 4.
Then we have:
domain: (4, ∞).
range: (-∞, ∞).
