Pls help this is pretty urgent
laiz [17]

Answer:

(a)  See below.

(b)  x = 0 or x = 1

(c)  x = 0 removable, x = 1 non-removable

Step-by-step explanation:

Given rational function:

f(x)=\dfrac{\ln |x-1|}{x}

<u>Part (a)</u>

Substitute x = 2 into the given rational function:

\begin{aligned}\implies f(2) & =\dfrac{\ln |2-1|}{2}\\\\ & =\dfrac{\ln 1}{2}\\\\ & =\dfrac{0}{2}\\\\ & =0\end{aligned}

Therefore, as the function is defined at x = 2, the function is continuous at x = 2.

<u>Part (b)</u>

Given interval:  [-2, 2]

Logs of negative numbers or zero are undefined.  As the numerator is the natural log of an <u>absolute value</u>, the numerator is undefined when:

|x - 1| = 0 ⇒ x = 1.  

A rational function is undefined when the denominator is equal to zero, so the function f(x) is undefined when x = 0.

So the function is discontinuous at x = 0 or x = 1 on the interval [-2, 2].

<u>Part (c)</u>

x = 1 is a <u>vertical asymptote</u>.  As the function exists on both sides of this vertical asymptote, it is an <u>infinite discontinuity</u>.  Since the function doesn't approach a particular finite value, the limit does not exist.  Therefore, x = 1 is a non-removable discontinuity.

A <u>hole</u> exists on the graph of a rational function at any input value that causes both the numerator and denominator of the function to be equal.

\implies f(0)=\dfrac{\ln |0-1|}{0}=\dfrac{\ln 1}{0}=\dfrac{0}{0}

Therefore, there is a hole at x = 0.

The removable discontinuity of a function occurs at a point where the graph of a function has a hole in it.   Therefore, x = 0 is a removable discontinuity.

A rectangular prism is 7 cm long, 4 cm wide and 4 cm tall. How many 2 times 2 times 2 cm cubes can the prism be cut into? What i
Fantom [35]

Answer: The number of 2 times 2 times 2 cm cubes is 14. The total surface area of all the 2 times 2 times 2 times cm cubes is 336 cm square. The total volume of all the 2 times 2 times 2 times cm cubes is 112 cm cube.

Explanation:

It is given that the A rectangular prism is 7 cm long, 4 cm wide and 4 cm tall.

The volume of rectangular prism is,

V_1=l\times b\times h

V_1=7\times 4\times 4

V_1=112

Therefore, the volume of rectangular prism is 112 cm square.

The volume of cubes is,

V_2=a^3

V_2=(2)^3

V_2=8

The number of cubes in the rectangular prism is,

N=\frac{V_1}{V_2} =\frac{112}{8} =14

Therefore, the number of cubes is 14.

Total surface area of a cube is,

A=6a^2

A=6(2)^2

A=24

Total surface area of all cubes is,

14\times A=14\times 24=336

Therefore the total surface area of all cubes is 336 cm square.

Total volume of all cubes is equal t the volume of rectangular prism, i.e, 112 cm cube.

X2 -5x+6<br> To solve a quadratic equation, start by factoring,
Y_Kistochka [10]

Answer:

x=2 OR x=3

Step-by-step explanation:

Given equation:

x^2 -5x+6=0

Solving the equation for 'x':

Using factorization method:

x^2-2x-3x+6=0

Making the factors by taking common:

x(x-2)-3(x-2)=0\\(x-2)(x-3)=0

x-2=0\\\\x=2

OR

x-3=0\\\\x=3
