Find the quotient. -300x5y4 ÷ xy2 -150 x6y6 -300 x6y6 300 x4y2 -300 x4y2

exis [7]

Answer:

d. -300 x4y2

Step-by-step explanation:

Here is the correct question: Find the quotient. -300x5y4 ÷ xy2

a. -150 x6y6

b. -300 x6y6

c. 300 x4y2

d. -300 x4y2.

Given: -300x5y4 ÷ xy2

Now, simplifying it

Using law of indices to solve it.

= $-300x^{5} y^{4} \div xy^{2}$

we know, $\frac{x^{m} }{x^{n} } = x^{m-n}$

= $-300x^{5-1} y^{4-2}$

= $-300x^{4} y^{2}$

Hence, the answer is $-300x^{4} y^{2}$

$\bf f(x)=x^2e^{-2x}\\\\
-----------------------------\\\\
\cfrac{dy}{dx}=2xe^{-2x}+x^2\cdot -2e^{-2x}\implies \cfrac{dy}{dx}=xe^{-2x}(2-2x)
\\\\\\
\cfrac{dy}{dx}=\cfrac{x(2-2x)}{e^{2x}}\implies 0=\cfrac{x(2-2x)}{e^{2x}}
\\\\\\
0=x(2-2x)\implies 
\begin{cases}
0=x\\
0=2-2x\implies 2x=2\implies x=1
\end{cases}$

now, bear in mind, that zeroing out the denominator, also gives critical points, usually asymptotic points, where the derivative is undefined, now, in this case, the denominator is never zero, so we don't get any from the denominator, just from the numerator, and are 0 and 1

now check the picture below

running a first-derivative test on it, those are the values on those regions

you get a negative, regardless of what it might be, what matters is the sign
you get a positive, and then a negative

so, f(x) goes down, then up then down

now, you can see, there's on relative minimum and a relative maximum
