Nikitich [7]

Answer:

6 students at the preschool of four years old attended the full day program.

Step-by-step explanation:

Given:

Number of four years old students = 16

fraction of four years old students attended full day program = \frac{3}{8}

We need to find the number of four years old students attended the full day program.

Solution:

Now we can say that;

number of four years old students attended the full day program is equal to fraction of four years old students attended full day program multiplied by Number of four years old students.

framing in equation form we get;

number of four years old students attended the full day program = \frac38\times 16 =6

Hence 6 students at the preschool of four years old attended the full day program.

If m(x) =x+5/x-1 and n(x) =x-3 which function has the same domain as (m.n)(x)
Travka [436]

Answer:

Step-by-step explanation:

m (x) = (x+ 5) / (x -1)        and     n(x) = x - 3.

m(x) = \dfrac{x+5}{x-1}

Hence

m(n) = \dfrac{n+5}{n-1}

but n is a function and n = x-3. Now, replace value of n on m (n)

(m(n))= \dfrac{(x-3)+5}{(x-3)-1}

simplify it

(m\bullet n)(x) =\dfrac{x+2}{x-4}\\

since (m . n) (x)  is a fraction function, its domain will be all x such that the denominator is NOT 0. That is

x-4\ne 0\rightarrow x\ne 4

among options, only C has the same denominator with (m\bullet n)(x)

Hence their domains are the same.
