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)}

Rhion sat maths and English test
Sauron [17]

Answer:

Rhion did better in maths test.

Step-by-step explanation:

Given that:

Rhion scored 14 out of 17.

We will find percentage and then compare them.

Percentage = \frac{Score}{Total\ marks}*100

Percentage = \frac{14}{17}*100

Percentage = 82.35%

Rhion scored 31 out of 39.

Percentage = \frac{31}{39}*100

Percentage = 79.48

On comparing,

82.35 > 79.48

Hence,

Rhion did better in maths test.

Which of the following statements are true about the graph below? Select all that apply.
Ann [662]

Answer:

The domain of the function is the set of all real numbers; the range of the function is the set of all nonnegative real numbers; the graph has an intercept at (0, 0); and the graph is symmetric with respect to the y-axis.

Step-by-step explanation:

This is not a square root function, this is a quadratic function, which has an x².

The domain, or set of x-values, is all real numbers.  This is because all numbers work for x.

The range, or set of y-values, is the set of all nonnegative real numbers.  This is because all numbers we get for y are positive real numbers.

The graph intersect both the x- and y-axis (x-intercept and y-intercept) at (0, 0).

The graph is decreasing on the interval x<0 and increasing on the interval x>0, not the other way around.

The graph has a minimum at (0, 0), not a maximum.

The graph can be folded in half along the y-axis, so it is symmetric with respect to the y-axis.
