Answer:
l : b = 6 : 5
Step-by-step explanation:
let's assume lenght of each congruent rectangle be x
now,
Lenght of the larger rectangle =
=》3 × lenght of smaller rectangle = 3x
but it is also equal to
=》4 × width of each smaller rectangles ( b )
so, we get :-
=》4 × b = 3x
=》b = 3x / 4
so, we get width of smaller rectangle =
now, width of larger rectangle =
=》lenght of smaller rectangle + (2 × width of smaller rectangle)
=》
=》
=》
=》
now, length of larger rectangle = 3x
width of larger rectangle = 5x/2
so l : w :-
=》
=》
=》
so, required ratio of l : b = 6 : 5
The domain is the set of all point where you can evaluate the function.
As you can see, the first piece is defined from -infinity to 2 (included).
The second piece is defined from 2 to 6 (excluded).
The third piece is defined from 6 (excluded) to +infinity.
So, the domain of the function is composed by all the real numbers which are not 6:
As for the range, it is the set of all values taken by the function. We can see that the first piece spans the y axis from 0 to infinity.
The second piece is constantly equal to 2, so it adds nothing.
The third piece spans the y axis from -2 to -infinity, so the range is
