Finding Derivatives Implicity In Exercise,Find dy/dx implicity.<br> x2e - x + 2y2 - xy = 0

Klio2033 [76]

Answer:

the question is incomplete, the complete question is

"Finding Derivatives Implicity In Exercise,Find dy/dx implicity . $x^{2}e^{-x}+2y^{2}-xy$ "

Answer : $\frac{dy}{dx}=\frac{y-(2-x)xe^{-x}}{(4y-x)}$

Step-by-step explanation:

From the expression $x^{2}e^{-x}+2y^{2}-xy$ " y is define as an implicit function of x, hence we differentiate each term of the equation with respect to x.

we arrive at

$\frac{d}{dx}(x^{2}e^{-x )+\frac{d}{dx} (2y^{2})-\frac{d}{dx}xy=0\\$

for the expression $\frac{d}{dx}(x^{2}e^{-x})$ we differentiate using the product rule, also since y^2 is a function of y which itself is a function of x, we have

$(2xe^{-x}-x^{2}e^{-x})+4y\frac{dy}{dx}-x\frac{dy}{dx} -y=0\\\\(2-x)xe^{-x}+(4y-x)\frac{dy}{dx}-y=0 \\$ .

if we make dy/dx subject of formula we arrive at

$(4y-x)\frac{dy}{dx}=y-(2-x)xe^{-x}\\\frac{dy}{dx}=\frac{y-(2-x)xe^{-x}}{(4y-x)}$

a rectangular plot of land has the length of 4/7 mile and a width of 3/8 mile. what is the area of this plot?

Tomtit [17]

Answer:

3/14 of a mile

Step-by-step explanation:

It is asking for area. The area of a rectangle is base times height

A = bh

the length can be either the base or the height. It won't matter for this question. Same goes for the width. Lets use 4/7 as the base, and 3/8 as the height.

So

A = (4/7)(3/8)

*When multiplying fractions, multiply the numerators together, and multiply the denominators together, then simplify the resulting fraction.

A = (4/7)(3/8) becomes

A = 12/56 which reduces to

A = 3/14 (both 12 and 56 are divisible by 4)
