y+4=-12/7(x-1) in standard form

Answers

Answer: y + [tex]\frac{12}{7}[/tex]x = -[tex]\frac{16}{7}[/tex]

Step-by-step explanation:

Standard form is Ay + Bx = C,

Given:

y+4=-12/7(x-1)

Rewrite:

y + 4 = [tex]\frac{-12}{7}[/tex](x - 1)

Distribute:

y + 4 = [tex]\frac{-12}{7}[/tex]x + [tex]\frac{12}{7}[/tex]

Subtract 4 from both sides:

y = [tex]\frac{-12}{7}[/tex]x + [tex]\frac{12}{7}[/tex] - 4

Add [tex]\frac{12}{7}[/tex]x to both sides:

y + [tex]\frac{12}{7}[/tex]x = + [tex]\frac{12}{7}[/tex] - 4

Combine like terms:

y + [tex]\frac{12}{7}[/tex]x = -[tex]\frac{16}{7}[/tex]

Rounded to the nearest tenth of a centimeter, what is the length of arc lmn? 7.9 cm 10.2 cm 12.6 cm 14.2 cm

Answers

The length of arc LMN is the number of units on the arc

The length of arc LMN is 14.2 cm

How to calculate the length of the arc?

The given parameters are:

Arc LM = 6.3 cmRadius, r = 6 cmAngle MON = 75 degrees

Start by calculating the length of arc MN using:

[tex]MN = \frac{\theta}{360} * 2\pi r[/tex]

So, we have:

[tex]MN = \frac{75}{360} * 2 * 3.14 * 6[/tex]

Evaluate the product

MN = 7.85

The length of arc LMN is then calculated using:

LMN = LM + MN

This gives

LMN = 6.3 + 7.85

Evaluate the sum

LMN = 14.15

Approximate

LMN = 14.2

Hence, the length of arc LMN is 14.2 cm

Original cost: $25,000

Depreciation rate: 8%

Term: 7 years

Formula for Depreciation:

A = C ( 1 - ( r ) (t) )

A = Future Value

C = Original Cost

r = rate

t = term

Solution:

Substitute the given values to the formula for depreciation.

A = $25,000( 1 - ( 0.08)(7))

A = $25,000( 1 - .56 )

A = $25,000(0.44 )

The length of a rectangular garden is 2 m greater than the width. The area is 80 m^2. Find the dimensions of the garden.

The width of the garden is ___m.
The length of the garden is ___m.

Answers

Answer:

Length of rectangle = 10 mWidth of the Rectangle = 8 m

Step-by-step explanation:

Given :-

Length of a Rectangular garden is 2m greater than the width .Area of garden = 80 m²

To Find :-

Dimensions of the garden

Solution :-

Let's assume:

Width of the rectangle = xLength of the rectangle = x + 2

We know that,

Area of rectangle = Length × Width

↠ (x)(x + 2) = 80

↠ x² + 2x - 80 = 0

↠ x² + 10x - 8x - 80 = 0

↠ x(x +10) -8 (x + 10) = 0

↠ (x-8) (x + 10) = 0

↠ x = 8 or -10

↠ x = 8

Hence,

Width of the rectangle = x = 8 mLength of the rectangle = x + 2 = 10 m

Answer:

Given:-

Length of rectangular garden is 2m longer than its widthArea of Rectangular garden is 80m²

To Find :-

Dimensions of Rectangular garden

Solution:-

Let the width be x and length be x + 2

According to the question ,

Area = 80m²

putting the known values ,

(X)(X+2) = 80m

x² +2x - 80= 0

x² +10x-8x -80m= 0

x(x + 10) - 8(x+10) = 0

(x-8) = 0 ; (x+10) = 0

X = 8 ; X = -10

As dimensions can not be negative so , X = 8

Length = X + 2 ; 10 m

Width = X ; 8 m

Decide whether y is a function of x.
x2 + y2 = 1

Answers

Answer:

Not a function.

Explanation:

x² + y² = 1 is not a function.

Here's the breakdown!

Looking at the type of equation, It is a circle equation.

In a circle equation, y value is not completely determined by the x value.

Shown:

x² + y² = 1y² = 1 -x²y = ±√1 -x²

There are multiple values of x for each value of y

Answer:

A function can be described as one-to-one or many-to-one, i.e. each value in the domain ([tex]x[/tex]-values) is mapped to a single value in f(x).

An example of a one-to-one function is a linear function. For every value of x there is one value of y.

An example of a many-to-one function is a quadratic function, where 2 different x-values map to one y-value.

[tex]x^2+y^2=1[/tex] is not a function as some values of [tex]x[/tex] are mapped to two different values of f(x).

For example, let x = 0.5

[tex]\implies (0.5)^2+y^2=1[/tex]

[tex]\implies y^2=0.75[/tex]

[tex]\implies y=\pm\sqrt{0.75}[/tex]

So as x = 0.5 maps to √0.75 and -√0.75, it is one-to-many, and is therefore not a function.

Pythagoras

c² = a² + b²

A linear function has a constant rate of change. However, the y values in the table do not have a constant rate of change. 4pi - pi = 3 pi, 9pi - 4pi = 5pi and so on. The values change each time, so it is a nonlinear function.

The mean of the data is 1.31, while the mean absolute deviation is 2.56.

What is the Mean Absolute Deviation?

The mean is the average of a data set, while the mean absolute deviation is the average distance of the each data point from the mean.

Given the data:

3,2,2,5,4,1,3,4,1,0,3,2,1,1,6,3

Find the Mean:

Mean = (3 + 2 + 2 + 5 + 4 + 1 + 3 + 4 + 1 + 0 + 3 + 2 + 1 + 1 + 6 + 3)/16 = 41/16 Mean = 2.5625

Find the Mean Absolute Deviation:

Mean abosolute deviation = (3 - 2.5625) + (2 - 2.5625) + (2 - 2.5625) + (5 - 2.5625) + (4 - 2.5625) + (1 - 2.5625) + (3 - 2.5625) + (4 - 2.5625) + (1 - 2.5625) + (0 - 2.5625) + (3 - 2.5625) + (2 - 2.5625) + (1 - 2.5625) + (1 - 2.5625) + (6 - 2.5625) + (3 - 2.5625) / 16

Mean abosolute deviation = 21/16 = 1.3125

What is the length of the diagonal of the screen, to the nearest whole inch?
Enter your answer in the box

Answers

Answer

Step-by-step explanation

16/9=width/height

20 is the width of the computer monitor so you would put width as 20

20/x then you would cross multiply to find the height which is x.

20 x 9=180

Then you would divide 180 by 16.

180/16=11.25

So now you have the width and the height 20/11.25=width/height

Then you do the pythagorean theorem a^2+b^2=c^2=20^2+11.25^2=526.5.6^2.Then you would round you answer to get 526.6 Then you would find the square root of 526.6 which is 22.9. Then you would round the answer to get 23.

Step-by-step explanation:

The width is represented by the variable w in the given equation ...

w(2w +4) = 240

This is conveniently divided by 2. Writing in standard form lets us see potential factoring.

w(w +2) = 120

w² +2w -120 = 0

(w +12)(w -10) = 0 . . . . . . factor

w = -12 or w = 10 . . . . . width
