Given functions are
The total number of ducks and swans in the lake after n months can be determined by adding the functions s(n) and d(n).
Taking 2 as common, we get
Hence The total number of ducks and swans in the lake after n months is
So what is your question cause there isn't one
Answer:
*assuming you know the concept of proportionality*
since L is directly proportional to T, an increase in L will result in an increase in T
so the solution of the first part is increases
in part 2, y is inversely proportional to x
which means that an increase in y will result in a decrease in x and vice-versa
So the answer of the second part is decreases
in part 3, since x is directly proportional to y, an increase in x will result in an increase in y
The answer is 95.
First: find the area if the whole rectangle. To do so you would multiply lxw (10x12)
Second: you would find the area of the square. Squares have perfect sides so you would multiply 5x5.
Last: take the sums of both equations. So the it would be 120-25=95.
