Find the value of the derivative (if it exists) at the indicated extremum. (If an answer does not exist, enter DNE.)

Liono4ka [1.6K]

Answer:

The answer is "0".

Step-by-step explanation:

Please find the correct question in the attached file.

Given value:

$\to f(x) =\frac{x^2}{x^2+5}\\\\$

Formula:

$\bold{\frac{d}{dx} \frac{u}{v} = \frac{ v \frac{du}{dx} - u \frac{dv}{dx}}{v^2}}$

$\to f'(x) =\frac{(x^2+5) 2x -2x^3 (2x)}{(x^2+5)^2}\\\\\to f'(0) =\frac{(0^2+5)2(0) -4(0)^4}{(0^2+5)^2}\\\\\to f'(0) =\frac{(0)(5) -2(0)}{(5)^2}\\\\\to f'(0) =\frac{0 - 0}{(5)^2}\\\\\to f'(0) =\frac{0}{25}\\\\\to f'(0) = 0$

Write a system of linear equations for the graph below.

sp2606 [1]

<h2>Answer:</h2>

We need to determine the equation of both lines first.

Line 1: <em>y = -2x + 3</em>

Line 2: <em>y = -1/3x - 2</em>

Now that we know the equations, we can set up a system of equations for this graph where both equations are in standard form.

Line 1:

$y = -2x + 3\\\\2x + y = 3$

Line 2:

$y = -\frac{1}{3}x - 2\\\\\frac{1}{3}x + y = -2$

<em>Final answer:</em>

$2x + y = 3\\\frac{1}{3}x + y = -2$

horrorfan [7]

Answer: The price of each gift is $5.

Step-by-step explanation:

Since we have given that

Amount = $300

Divided into equally among 5 fourth grade teachers.

so, Amount each fourth grade teacher would be

$\dfrac{300}{5}=\$60$

Since Number of hits that need to buy = 12

Each cost the same amount.

So, Price of each gift would be

$\dfrac{60}{12}=\$5$

Hence, the price of each gift is $5.
