Answer:

The assertion that g(f(x)) is continuous at c is true.

Step-by-step explanation:

let\\a=\lim_{x\rightarrow c}f(x)

\because f(x) is continuous at c

\\\\Similarly\\\\b=\lim_{x\rightarrow f(c)}g(x)

\because g(x) is continuous at \ x=f(c)

\lim_{x\rightarrow c }g(f(x))=g(f(c))\\\\=g(a) which is defined as per given data thus g(f(x)) is continuous at x=c

What is the value of x?<br><br> Enter your answer in the box.<br><br> x =
Assoli18 [71]

Answer:

x = 5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 12² = 13², so

x² + 144 = 169 ( subtract 144 from both sides )

x² = 25 ( take the square root of both sides )

x = \sqrt{25} = 5
