For what values of the variable does the following expression make sense: three times the square root of "a"

Using the domain concept, it is found that the expression makes sense for values of a that are of 0 or greater, than is,

The domain of a data-set is the set that contains all possible input values.

In this problem, the expression "three times the square root of a" is given by:

The square root function is valid for non-negative values, hence the domain of is , which are the values for which the expression makes sense.

This question revolves around the concept of domain (primarily) and range (secondarily).  The domain of the square root function is [0, +infinity).

The domain of "three times the sqrt of a" shares that domain:  [0, +infinity).

We were not asked to come up with the range, but if the range is wanted, it is

[0, +infinity).

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
