If f(x) = -x-2, what is f¹(x)?
astra-53 [7]

Answer:

  1. f¯¹(x) =9x+18, for the pictorial(image) question
  2. what is the send question is it asking derivative or inverse
  3. If it is inverse f¯¹(x)=-x-2 as it is
  4. Or if it is derivative f'(x)=-1

Step-by-step explanation:

<h2>For the image question f(x)=1/9x-2,f¯¹(x)=?</h2>
  • f(x)=1/9x-2............given
  • y=1/9x-2................swapping f(x) by y to Easily write
  • x=1/9y-2................interchanging x and y
  • 1/9y-2=x................changeling side of equation
  • 9(1/9y-2)=(x)9.......multiplying both sides by 9 to override the fraction on the right side
  • y-18=9x
  • y=9x-18.................Return to where it were
  • <em><u>f¯¹(x)=9x+18</u></em>..........swap back f¯¹(x) in the y

<h2>For the question f(x)=-x-2,f¯¹(x)=?</h2>
  • following the ☝️ arrangement
  • y=-x-2
  • x=-y-2
  • -y-2=x
  • -y=x+2
  • y=-x-2
  • f¯¹(x)=-x-2

nasty-shy [4]
1/4 times 2 2/3 = 2/3

Change from a mixed number to improper fraction: 1/4 times 8/3

Multiply across so 1x8/4x3 to get 8/12

Simplify to 2/3

What is the 44th decimal digit in the decimal representation of 1/11?
Alexus [3.1K]
The decimal representation of  1/11  is  0.090909...
The pair of digits '09' repeat forever.

If you start counting the digits after the decimal point,
the odd ones are all zero, and the even ones are all  9 .

So the 44th digit after the decimal point is  9 .

Total blood cholesterol level was measured for each of
laiz [17]
<h3>Answer: Mean = 218.9.</h3><h3>Median = 229</h3><h3>Mode = Zero mode.</h3>

Step-by-step explanation:

Given blood cholesterol level was measured for each of 8 adults (in mg/dL) are:

264, 191, 160, 148, 262, 212, 268, 246

In order to find the mean, we need to add all those 8 numbers and divide by 8.

Therefore, mean = \frac{264+191+160+148+262+212+268+246}{8} =\frac{1751}{8} =218.9.

<h3>Mean = 218.9.</h3>

In order to find the median, we need to arrange them in ascending order:

148, 160, 191, 212, 246, 262, 264, 268.

The middle most two values are 212 and  246.

Therefore, median = \frac{212+246}{2} =\frac{458}{2} = 229.

<h3>Median = 229.</h3>

\mathrm{The\:mode\:is\:the\:term\:in\:the\:data\:set\:that\:appears\:the\:most.}

\mathrm{If\:there\:is\:more\:than\:one\:term\:that\:appears\:the\:most,\:then\:there\:is\:no\:mode.}

\mathrm{Count\:the\:number\:of\:times\:each\:element\:appears\:in\:the\:list}

\begin{pmatrix}148&160&191&212&246&262&264&268\\ 1&1&1&1&1&1&1&1\end{pmatrix}

\mathrm{The\:most\:common\:element\:is\:not\:unique,\:so\:there\:is\:no\:mode}

<h3>Therefore, Mode = Zero mode.</h3>
