Answer:

Option 3

Step-by-step explanation:

Given functions are,

f(x) = \frac{1}{x-3}

g(x) = \sqrt{x+5}

Therefore, composite function (f o g) will be,

(f o g)(x) = f[g(x)]

             = \frac{1}{\sqrt{x+5} -3}

This function will be defined for,

Denominator > 0

\sqrt{x+5}-3>0

\sqrt{x+5} >3

(x+5)>3^2

x+5>9

x>9-5

x>4

And x+5\geq 0

x\geq -5

Therefore, domain of the composite function will be,

[-5, 4) ∪ (4, ∞)

Option 3 will be the answer.

Answer:

1344 ft^2

Step-by-step explanation:

From the picture we can see that 4w = 3l, which means that l = (4/3)w.  Since w = 12 ft, l = (4/3)(12 ft) = 16 ft.  Then the total area of the floor is

(length of floor)(width of floor) = (48 ft)(12 ft + 16 ft) = 1344 ft^2

k > 13

Step-by-step explanation:

k+6 > 19\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:k > 13\:\\ \:\mathrm{Interval\:Notation:}&\:\left(13,\:\infty \:\right)\end{bmatrix}

\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}

k+6-6 > 19-6

\mathrm{Simplify}

k > 13

Thus, the answer is k > 13
