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:

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

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

Find the area of the triangles round to the tenth. Show steps please!

amm1812

Answer:

$\large\boxed{A=89.6}$

Step-by-step explanation:

It's the right triangle. The formula of an area of a right triangle:

$A=\dfrac{leg\cdit leg}{2}$

We have:

$leg=x\\leg=16\\\text{and the angle}\ \alpha=55^o$

Use tangent:

$tangent=\dfrac{opposite}{adjacent}$

$opposite=16,\ adjacent=x$

$\tan55^o\approx1.4281$

Substitute:

$\dfrac{16}{x}=1.4281$ convert the decimal to the fraction

$\dfrac{16}{x}=\dfrac{14281}{10000}$ cross multiply

$14281x=160000$ divide both sides by 14281

$x=\dfrac{160000}{14281}$

$x\approx11.2$

Calculate the area:

$A=\dfrac{(16)(11.2)}{2}=89.6$

The product of 3/4 and a number s is 3/5

vazorg [7]

Product= multiplication
s= a number
is= equal sign

3/4s= 3/5
divide both sides by 3/4

s= (3/5) / (3/4)
to divide fractions, multiply by the reciprocal/inverse of 3/4

s= 3/5 * 4/3
multiply numerators; multiply denominators

s= (3*4)/(5*3)
multiply within parentheses

s= 12/15
simplify by 3

s= 4/5

ANSWER: 4/5

Hope this helps! :)
