Mrs. ishimitsu is installing a rubber bumper around the edge of her coffee table. the dimensions of the rectangular table are (2x2 – 16) feet and (–x2 + 4x + 1) feet. which expression represents the total perimeter of the table, and if x = 3, what is the length of the entire rubber bumper
44.54435 is the answer
to get this you look at 44.544349 then you look at the number behind the 4 and if it's bigger than 5 the 4 increases by one so it''l be 5, but if the number is less than 5 it stays the same at 4.
for this case, we must indicate which of the given functions is not defined for
by definition, we know that:
has a domain from 0 to infinity.
adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. for it to be defined, the term within the root must be positive.
thus, we observe that:
is not defined, the term inside the root is negative when .
while if it is defined for
, your domain is given by all real numbers.
adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. in the same way, its domain will be given by the real numbers, independently of the sign of the term inside the root.
so, we have:
with x = 0: is defined.
with x = 0: in the same way is defined.
