If measure of angle 1 = 2x+6 and measure of angle 2 = 8x+4 where angles 1 and 2 are supplementary, then how much is the actual measure of angle 1?\

Answers

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°

(SAT Prep) In the figure, what is the value of y?
A. 20°

C. 40°
D. 30°

Answers

Answer:

60 degrees

I checked in the RSM system

The value of angle y is C. 40°.

Using Straight angle property we can solve this question.

First we'll find the value of x using the straight angle property:

x+ 0.5x + 3x = 180°

4.5x = 180°

x = 180°/4.5

x = 40°

Now using vertically opposite angles property we get:

0.5x = 0.5y

0.5* 40° = 0.5y

20° = 0.5y

y = 20/0.5

y = 40°

Therefore, the value of y is 40°.

b) When heated an iron bar expands by 0.2%. If the increase in length is 1 cm,
what is the original length of the bar ? ​

Answers

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].

Step-by-step explanation:

How to solve your question

Your question is 1/2(4x-2)=6x-3

Solve

1.Combine multiplied terms into a single fraction

1/2(4x-2)=6x-13

1(4x-2) divided by 2 =6x-13

2.Multiply by 1

3 Subtract 6x from both sides of the equation

4.Simplify

5.Multiply all terms by the same value to eliminate fraction denominators

6.simplify

7.Add 2 to both side of equation

8.Simplify

9.Divide both sides of the equation by the same term

10.Simplify

Step-by-step explanation:

Combine multiplied terms into a single fraction

1/2 (4x-2) / 2 = 6x - 13

1 (4x -2) /2 = 6x -13

Multiply by 1

1 (4x - 2) / 2 = 6x - 2

4x - 2 / 2 = 6x-13

Subtract 6x from both sides of the equation

4x - 2 / 2 = 6x - 3

4x - 2 /2 - 6x =6x -13 -6x

Simplify

Combine like terms

4x -2 /2 -6x = -13

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

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)

Hence AC parallel SB

So ABCS is a parallelogram
And we know that in parallelogram opposite sides are equal so AC = SB

5x - 3x = 8

D.) The slope of p(x) is half the slope of m(x)

Answers

Answer:

your ansewer would be C

Step-by-step explanation:

i hope this helped you

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.

What is the slope?

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)".

[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:

[tex]\frac{d}{dx} (3x^3 + 2xy + 4y^2 = 0)[/tex]

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:

[tex]9x^2 + (2x \times \frac{dy}{dx} + y \times 2) + 8y \times \frac{dy}{dx} = 0[/tex]

Simplify.

[tex]9x^2 + 2x\frac{dy}{dx} + 2y + 8y \frac{dy}{dx} = 0[/tex]

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.

[tex]2x\frac{dy}{dx} +8y \frac{dy}{dx} = -9x^2-2y[/tex]

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

[tex]\frac{dy}{dx}(2x+8y) = -9x^2-2y[/tex]

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

[tex]\frac{dy}{dx}= \frac{-9x^2-2y}{2x+8y}[/tex]

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

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

What is subject of formula?

The subject of a formula is the variable that is being worked out. It can be recognized as the letter on its own on one side of the equals sign.

In order to change the subject of a formula, or rearrange a formula, items in the formula need to be rearranged so a different variable is the subject. Knowledge of solving equations and inverse operations is very useful.

Given formula.

m = t + 1 / t - 3

m ( t - 3) = t - 1

mt - 3m = t - 1

mt - t = 3m - 1

t(m - 1) = (3m - 1)

t = (3m -1) / (m - 1)

Hence, the formula becomes t = (3m -1) / (m - 1).
