Use the definition of continuity and the properties of limits to show that the function f(x)=x sqrtx/(x-6)^2 is continuous at x
qaws [65]

Answer:

The function is  continuous at  x = 36

Step-by-step explanation:

From the question we are told that

      The  function is f(x)  =  x *  \sqrt{ \frac{x}{ (x-6) ^2 }  }  

       The  point at which continuity is tested is  x =  1

Now from the definition  of continuity ,

   At function is continuous at  k if  only  

       \lim_{x \to k}f(x)  =  f(k)

So

      \lim_{x \to 36}f(x)  =  \lim_{n \to 36}[x *  \sqrt{ \frac{x}{ (x-6) ^2 }  }]

                            = 36 *  \sqrt{ \frac{36}{ (36-6) ^2 }  }

                             = 7.2

Now  

     f(36) = 36  *  \sqrt{ \frac{36}{ (36-6) ^2 }  }

     f(36) = 7.2

So  the given function is continuous at  x =  36

because

          \lim_{x \to 36}f(x)  =  f(36)

The measure of C if a=6 and b=9.
kirill115 [55]

Answer:

c=3\sqrt{13}

Step-by-step explanation:

Pythagorean Theorem: In the right triangle the square of longer side is equal to the sum of the squares of other sides.

c^2=a^2+b^2\\\\c^2=6^2+9^2\\\\c^2=36+81\\\\c^2=117\\\\c^2=3\times 3\times 13\\\\c=\sqrt{3\times 3\times 13}\\\\c=3\sqrt{13}

A new health drink has 120% of the recommended daily allowance (RDA) for a certain vitamin is 40 MG. How many milligrams of the
Alika [10]

Answer:

We conclude that the number of milligrams of the vitamin in the drink will be: 48 mg

Step-by-step explanation:

The amount of certain Vitamin = 40 mg

Given that a new health drink has 120% of the recommended daily allowance (RDA) for a certain vitamin is 40 MG.

Thus,

The number of milligrams of the vitamin in the drink:

120% of 40

= [120/100] × [40]

= 1.2 × 40

= 48

Therefore, we conclude that the number of milligrams of the vitamin in the drink will be: 48 mg
