If a chord of a circle is 6 and is twice as far from the center chord of length 12, how long is the radius of the circle?

Answers

Answer 1

Answer and explanation:

A center chord in a circle is the diameter of that circle. Therefore a center chord of a circle is different from other chords that touch two points on the circle but not in the center of the circle. A diameter of a circle is the chord that runs the length of the center of the circle touching two points at the edge of the circle. A diameter is twice the radius of the circle. So if the diameter of the circle is 12cm then the radius of the circle is 6cm

The angles shown are supplementary. (3x + 15)° 60° What is the value of x?​

Answers

Answer:

x = 35

Step-by-step explanation:

Supplementary angles add up to 180°.

if (3x + 15)° and 60° are supplementary, then

3x + 15 + 60 = 180

now, you just have to solve the equation.

3x + 75 = 180

3x = 105

x = 35

Check

3*35 + 15 + 60 = 180

105 + 15 + 60 = 180

180 = 180

Show two different ways to find the solution.Part B: The paintings have areas of 1,600in^2 and 484in^2, respectively. A potential buyer went to an exhibition and argued that the value of xfor both paintings is the same. Is he right? Prove it.

Answers

Answer:

56x² - 120x + 16 ; (9x - 5)² - (5x - 3)²

x in both equations is 5

Step-by-step explanation:

Painting 1 : 81x^2 - 90x + 25

Painting 2 : 25x^2 + 30x + 9

Expression for the difference between the two paintings :

Painting 1 - painting 2

(81x^2 - 90x + 25) - (25x^2 + 30x + 9)

81x^2 - 90x + 25 - 25x^2 - 30x - 9

81x² - 25x² - 90x - 30x + 25 - 9

56x² - 120x + 16

2.)

81x^2 - 90x + 25 = 1600in²

25x^2 + 30x + 9 = 484 in²

Factorizing each equation :

81x^2 - 90x + 25 = 1600 in²

(9x - 5)^2 = 1600 in²

25x^2 + 30x + 9 = 484 in²

(5x - 3)^2 = 484

(9x - 5)² - (5x - 3)²

2.)

(9x - 5)^2 = 1600

Take square root of both sides

9x - 5 = 40

9x = 40 + 5

9x = 45

x = 45/9

x = 5

(5x - 3)^2 = 484

Take square root of both sides

5x - 3 = 22

5x = 22 + 3

5x = 25

x = 25/5

x = 5

Use the midpoint formula to estimate the sales of Cars, Inc. in 2009, given the sales in 2008 and 2010. Assume that the sales of Cars, Inc. sales always follow a linear pattern. (Round to nearest whole number) Year Sales (in millions) 2008 240 2010 280 millions Enter the answer​

Answers

Answer:

The estimated sales were $260 million

Step-by-step explanation:

Assume the endpoints of a segment are (x1,y1) and (x2,y2).

The midpoint (xm,ym) is calculated as follows:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

The sales ov Cars, Inc. were (2008,240 million) and (2010,280 million). We need to use the midpoint to estimate the sales in 2009:

[tex]\displaystyle x_m=\frac{2008+2010}{2}=2009[/tex]

[tex]\displaystyle y_m=\frac{240+280}{2}=260[/tex]

Three vertices of a parallelogram are shown in the figure below. Give the coordinates of the fourth vertex.
Coordinates: (-3,8) (4,5) (2,-5)

Answers

Given:

The three vertices of a parallelogram are (-3,8), (4,5), (2,-5).

To find:

The fourth vertex of the parallelogram.

Solution:

Let the vertices of the parallelogram are A(-3,8), B(4,5), C(2,-5) and D(a,b).

We know that, diagonals of a parallelogram bisect each other. It means midpoints of both diagonals are same.

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Two diagonals of ABCD are AC and BD.

Midpoint of AC = Midpoint of BD

[tex]\left(\dfrac{-3+2}{2},\dfrac{8-5}{2}\right)=\left(\dfrac{4+a}{2},\dfrac{5+b}{2}\right)[/tex]

[tex]\left(\dfrac{-1}{2},\dfrac{3}{2}\right)=\left(\dfrac{4+a}{2},\dfrac{5+b}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{4+a}{2}=\dfrac{-1}{2}[/tex]

[tex]4+a=-1[/tex]

[tex]a=-1-4[/tex]

[tex]a=-5[/tex]

And,

[tex]\dfrac{5+b}{2}=\dfrac{3}{2}[/tex]

[tex]5+b=3[/tex]

[tex]b=3-5[/tex]

[tex]b=-2[/tex]

Therefore, the coordinates of fourth vertex are (-5,-2).

Elizabeth purchased a $20 bus pass. Each time she rides the bus $1.25 is deducted from the pass. What equation would represent this scenario? *
12 points
y= 1.25x - 20
y= -1.25x + 20
y= 20x - 1.25
y= 20x + 1.25

Answers

Answer:

Y = 1.25x - 20

Step-by-step explanation:

Everytime she rides the bus 1.25 is taken away from that 20.

The x = Every ride

For example

say she rode the bus 5 times so it would be

1.25 × 5 = 6.25 now you take the answer and subtract it from the 20

20 - 6.25 = 13.75
