The question is not properly formatted.

<em>Assume that the given parameter is: 4</em>

Required

The multiplicative inverse

Let a number be x, and the multiplicative inverse be y. The relationship between them is:

$y * x = 1$

Make y the subject

$y = \frac{1}{x}$

So;; for the assumed given parameter.

The multiplicative inverse is:

$y = \frac{1}{4}$

The left side of a solid block is held at a constant temperature of 200°C. The temperature profile within the block is given by

Nikitich [7]

Answer:

with T = 50⁰C, we have:

50 = 200 - 5x - x²

<=> x² + 5x = 150

<=> x² + 5x - 150 = 0

=> x = 10

Can't figure it out!!

Zanzabum

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby 
\begin{array}{llll}
average\ rate\\
of\ change
\end{array}\\\\
-------------------------------\\\\
f(x)= \cfrac{1}{x} \qquad 
\begin{cases}
x_1=2\\
x_2=b
\end{cases}\implies \cfrac{f(b)-f(2)}{b-2}=-\cfrac{1}{10}
\\\\\\
\cfrac{\frac{1}{b}-\frac{1}{2}}{b-2}=-\cfrac{1}{10}\implies 
\cfrac{\frac{2-b}{2b}}{b-2}=-\cfrac{1}{10}\implies \cfrac{2-b}{2b}=-\cfrac{b-2}{10}
\\\\\\
$

$\bf \cfrac{2-b}{2b}=\cfrac{2-b}{10}\implies 20-10b=4b-2b^2\impliedby cross-multiplying
\\\\\\
2b^2-4b-10b+20=0\implies 2b^2-14b+20=0
\\\\\\
b^2-7b+10=0\implies 
(b-2)(b-5)=0\implies b=
\begin{cases}
\boxed{5}\\
2
\end{cases}$

Any number that is divisible by 3 is divisible by nine

vovangra [49]

I think what you are trying to ask is what number is divisible by three and nine
multiply 3 and 9 to get your answer
= 27
27 because it can be divided by 3 and = 9 and can be divided by 9 and = 3
