Suppose that x and y are both differentiable functions of t and are related by the given equation. Use implicit differentiation

stepan [7]

Answer:

Let z = f(x, y) where f(x, y) =0 then the implicit function is

$\frac{dy}{dx} =$ $\frac{-δ f/ δ x }{δ f/δ y }$

Example:- $\frac{dy}{dx} = \frac{-(y+2x)}{(x+2y)}$

Step-by-step explanation:

Partial differentiation:-

Let Z = f(x ,y) be a function of two variables x and y. Then

$\lim_{x \to 0} \frac{f(x+dx,y)-f(x,y)}{dx}$ Exists , is said to be partial derivative or Partial differentiational co-efficient of Z or f(x, y)with respective to x.

It is denoted by δ z / δ x or δ f / δ x

Let Z = f(x ,y) be a function of two variables x and y. Then

$\lim_{x \to 0} \frac{f(x,y+dy)-f(x,y)}{dy}$ Exists , is said to be partial derivative or Partial differentiational co-efficient of Z or f(x, y)with respective to y

It is denoted by δ z / δ y or δ f / δ y

Implicit function:-

Let z = f(x, y) where f(x, y) =0 then the implicit function is

$\frac{dy}{dx} =$ $\frac{-δ f/ δ x }{δ f/δ y }$

The total differential co-efficient

d z = δ z/δ x + $\frac{dy}{dx}$ δ z/δ y

Implicit differentiation process

differentiate both sides of the equation with respective to 'x'

move all d y/dx terms to the left side, and all other terms to the right side

factor out d y / dx from the left side
Solve for d y/dx , by dividing

Example : $x^2 + x y +y^2 =1$

solution:-

differentiate both sides of the equation with respective to 'x'

$2x + x \frac{dy}{dx} + y (1) + 2y\frac{dy}{dx} = 0$

move all d y/dx terms to the left side, and all other terms to the right side

$x \frac{dy}{dx} + 2y\frac{dy}{dx} = - (y+2x)$

Taking common d y/dx

$\frac{dy}{dx} (x+2y) = -(y+2x)$

$\frac{dy}{dx} = \frac{-(y+2x)}{(x+2y)}$

A wooden board in the shape of a rectangular prism measures 0.3 m by 2.1 m by 0.1 m and has a mass of 0.07 kg.

Oksanka [162]

Density = Mass/Volume
D = M/V
D = 0.07/0.063
D = 1.111111111111111

Volume of a rectangular prism is WHL
Volume of a rectangular prism is 0.3 m * 2.1 m * 0.1 m
Volume of a rectangular prism is 0.063

PLEASE HELP ME ASAPPPPPP ty ty

Naddika [18.5K]

Answer:

y = -3x + 15

Step-by-step explanation:

The equation of the line parallel to the given line that contains point is:

3x + y - 15 = 0 (General form)

y = -3x + 15 (Slope y-intercept form)

Step 1: The slope of a given line is. m = -3

Step 2: Parallel lines have the same slope, so the slope of the unknown line (m1 ) will also be -3. So, the parallel line will have a slope of m1 = -3

Step 3: Now we have a point and the slope so we can use point-slope form, which is: y - y0 = m1 (x - x0)

In this example we have: m1 = -3 , x0 = 4 and y0 = 3 . After substitution we have:

y - y0= m1(x-x0)

y - 3 = -3(x - 4)

y - 3 = -3x + 12

y = -3x + 12 + 3

y = -3x + 15

heres a picture if you don't understand the steps I wrote
