In the context of relationships between variables, increases in the values of one variable are accompanied by increases in the v
TiliK225 [7]

Answer: Directly proportional.

Step-by-step explanation:

The increase of one variable which causes the other variable to increase points to a directly proportional relationship between the two variables. Similarly, the decrease of one variable will cause a decrease in the other variable.

One variable can also be the constant multiple of the other. This means that if one changes, the other one will change in PROPORTION to it.

Hi i just need help checking if my answer is correct I have been working on a implicit diffrention problem and I need some help.
SSSSS [86.1K]

Answer:

  \dfrac{dy}{dx}=\dfrac{-4x^3y+2y^3+3x^2y^3}{x^4-6xy^2-3x^3y^2}

Step-by-step explanation:

Normally, when I do this, I differentiate each term first with respect to x then with respect to y. In this solution, I differentiated the entire expression with respect to x, then with respect to y. That makes separating the dx and dy coefficients much easier, so the solution almost falls into your lap.

  -x^4 y + 2 x y^3 + x^3 y^3=0 \qquad\text{given}\\\\(-4x^3y+2y^3+3x^2y^3)dx+(-x^4+6xy^2+3x^3y^2)dy=0\\\\(-4x^3y+2y^3+3x^2y^3)dx=(x^4-6xy^2-3x^3y^2)dy\\\\\boxed{\dfrac{dy}{dx}=\dfrac{-4x^3y+2y^3+3x^2y^3}{x^4-6xy^2-3x^3y^2}}

the hypotenuse of a right angled triangle is 26cm, if the other side 24cm. find the length of the third side​
weeeeeb [17]

You need Pythagorean theorem for this.

a² + b² = c², where c is the hypotheneus and a and b are the sides of the right triangle.

24² + x² = 26²

x² = 676-576

x = ±√100

x = 10 (-10 is rejected because length of triangle cannot be a negative number)
