Answer:
.
For values of x>0, it can be rewritten as
Step-by-step explanation:
For the expression:
We can apply this logarithmical property:
Then,
If we assume values of <em>x </em>> 0 (non negative values for x), then the expression could be rewritten as follows:
, since
We have to remember that <em>domain</em> (all possible values x) for logarithmic function is for all x > 0, or mathematically expressed as:
Domain:
Answer:
220ft^2
Step-by-step explanation:
In red: 12ft - 10ft = 2ft and there 2 sides so 2ft / 2 = 1ft
In blue: 18ft - 12ft = 6ft
The missing area in dark blue: 6ft x 1ft = 6 / 2 = 3
total rectangle area: 12ft x 18ft = 216
216 - (3 + 3) = 216 - 6 = 200 subtract 6, we added that area in
