General Formulas and Concepts:

Algebra

Calculus

Step-by-step explanation:

Step 1: Define equation

3x³ + 2xy + 4y² = 0

Step 2: Find 1st Derivative

Step 3: Find Derivative (Solve for y')

Answer:

[tex]\frac{dy}{dx}= -\frac{9x^2+2y}{2(x+4y)}[/tex]

Step-by-step explanation:

Find the derivative of [tex]3x^3 + 2xy + 4y^2 = 0[/tex].

In order to find the derivative of this function, [tex]\frac{dy}{dx}[/tex], we can start by noticing that there are two variables in this problem, x and y.

Since we want the derivative with respect to x, every time we encounter the variable “y” in this problem we can change it to [tex]\frac{dy}{dx}[/tex]. We will see this happen later on in the solving process by using implicit differentiation.

Let’s start by taking the derivative of the entire function:

Using the Power Rule and the Product Rule, we can perform implicit differentiation on this equation. Let’s take the derivative of each separate piece in this function:

[tex]3x^3 \rightarrow 3(3x^3^-^1) \rightarrow 9x^2[/tex]                                   Power Rule

[tex]2xy \rightarrow (2x \times \frac{dy}{dx} + y \times 2)[/tex]                                Product Rule

[tex]4y^2 \rightarrow 2(4y) \times \frac{dy}{dx} \rightarrow 8y \times \frac{dy}{dx}[/tex]                 Power Rule & Implicit Differentiation

Let’s combine these steps into one comprehensive operation:

Simplify.

Keep all terms containing [tex]\frac{dy}{dx}[/tex] on the left side of the equation and move everything else to the right side of the equation. This way we can solve for [tex]\frac{dy}{dx}[/tex], which, in this case, is the derivative of the original function.

Subtract [tex]9x^2[/tex] and [tex]2y[/tex] from both sides of the equation.

Factor out dy/dx from the left side of the equation.

Divide both sides of the equation by (2x + 8y).

You can leave it in this form, or you can convert this to either:

Answer:

The perimeter of the isosceles triangle is 32 centimeters

Step-by-step explanation:

The perimeter of any figure is the sum of the lengths of outline sides

Let us use this fact to solve our question

∵ The perimeter of the triangle is the sum of the lengths of its 3 sides

∵ The triangle is an isosceles triangle

∵ The length of each two equal sides is 12 centimeters

∵ The length of the third side is 8 centimeters

→ Add the lengths of the 3 sides

∴ The perimeter of the triangle = 12 + 12 + 8

∴ The perimeter of the triangle = 32 centimeters

∴ The perimeter of the isosceles triangle is 32 centimeters

Simple algebra.

When we convert this to an equation we get: 0.2% of something is equal to 1 unit.

So here's the equation: [tex]0.02x = 1[/tex]

After we transpose [tex]0.02[/tex], the equation become: [tex]x = \frac{1}{0.02}[/tex].

Divide [tex]1[/tex] with [tex]0.02[/tex] and you get [tex]50[/tex].

So the length of the original bar is [tex]50[/tex] cm. :D

Answer:

8

Step-by-step explanation:

In Solving This You will Need To;

*First You Open The Bracket Which is

6×(2-8)+4

6×2-8+4

*So after this you will multiply the 6 by the 2 which is going to be;

12-8+4

*So after you have multiplied 6 by 2 you can choose to subtract the 8 from the 12 or you can also choose to add the -8+4 either way you choose you're going to arrive at the same answer. So I choose to subtract 8 from the 12 so it's going to be;

4+4

Then you add the four plus 4 so the final answer will be 8

(If I chose to add the -8+4 it would have been -4 so 12-4 would have also given me 8 so any step is acceptable)

Answer:

The actual measure of ∠1 = 40°

Step-by-step explanation:

We are given: ∠1 = 2x+6 and ∠2 = 8x+4

and both angles are supplementary. we need to find the actual measure of ∠1

Supplementary angles: If the angles are supplementary their sum is equal to 180°

In our case ∠1 +∠2 = 180°

2x+6+8x+4=180

Solving the equation to find x, then we can find the actual measure of ∠1

[tex]2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17[/tex]

So, value of x = 17

Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6

[tex]\angle1=2(17)+6\\\angle1=34+6\\\angle1=40[/tex]

So, the actual measure of ∠1 = 40°

Answer:

In a tape diagram, each of the lengths represents a fixed quantity of something.

Let's suppose that each one of these lengths represents a distance d.

We also know that the expert trail is 750 meters longer than the beginner one.

And in the tape diagram, the expert trail has 3 more lengths than the beginner trail, then we must have that the difference in distance must be equivalent with the difference in lengths.

750m = 3*d

d = 750m/3 = 250m

Then each length in the tape diagram represents 250m

With this we can find the length of each trail.

The beginner trail has 1 length, then it is 1*250m = 250 meters long.

The expert trail has 4 lengths, then it is 4*250m = 1000 meters long.

Answer:

Option (7)

Step-by-step explanation:

5x + 6y > 1

6y > -5x + 1

y > [tex]\frac{1}{6}(-5x+1)[/tex]

y-intercept of the line = [tex]\frac{1}{6}=0.167[/tex]

Shaded area will be above the dotted line y = [tex]-\frac{1}{5}x+\frac{1}{6}[/tex]

y - x < 0

y < x

As y-intercept of the line is zero, given inequality will pass through (0, 0).

And the shaded area will be below the line.

Therefore, graph shown in Option (7) will be the correct option.  

Answer:

Domain: -2 < x ≤ 3

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Since domain encompasses x values only, we are looking at the x-values of the graph. We see that our x-values span from -2 to 3. However, since x = -2 is a open dot, it is NOT included in the domain. Since x = 3 is a closed dot, it IS included in the domain:

(-2, 3] or -2 < x ≤ 3

The slope is the intensity of inclination thus the slope of p(x) is greater than the slope of m(x) thus option (A) is correct.

A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope is also calculated by differentiation for example slope of y = sinx will be y' = cosx.

As per the given function,

p(x) = 157.1x

p(x)/x = slope = 157.1

The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

In the function m(x) the slope will be as,

Slope = (188.4 - 125.6)/(3 - 2)

Slope = 62.8

Hence "The slope is the intensity of inclination thus the slope of p(x) is greater than the slope of m(x)".

Answer: x = 8

because  The upper triangle is an isosceles triangle (the two sides are equal)

=> 5x + 5 = 45°

<=> x = (45 - 5) : 5

<=> x = 40:5 = 8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

5x + 5 + 5x + 5 + 90 = 180, that is

10x + 100 = 180 ( subtract 100 from both sides )

10x = 80 ( divide both sides by 10 )

x = 8

b. odd

Step-by-step explanation:

f(-x)^3-2x(-x)

f(-x)=-x^3+2x

f(-x)=-(x^3-2x)

f(-x)=-f(x)

The given function f(x) = x³ - 2x is an odd function.

Given that,
To determine whether the given function is odd, even, or neither.

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
The given function is f(x) = x³ - 2x,
For the given function to be odd f(-x) = -f(x)
put x = -x in the function,
f(-x) = (-x)³ - 2(-x)
f(-x) = -x³ + 2x

Thus. the given function f(x) = x³ - 2x is an odd function.
