Find the domain of the graphed function.

Step-by-step explanation:

1.

the indicated point in the middle is the center point of the circle.

the line perpendicular to a chord going through that center solid the chord in half.

so,

x = 9

2.

Pythagoras

c² = a² + b²

13.5² = x² + 10.4²

182.25 = x² + 108.16

x² = 74.09

x = 8.607554821...

3.

Intersecting Chords Theorem

(part one of chord 1)×(part two of chord 1) =

= (part one of chord 2)×(part two of chord 2)

6x = 10×9 = 90

x = 90/6 = 30/2 = 15

4.

Intersecting Chords Theorem again

x(x+3) = 4×10 = 40

x² + 3x = 40

x² + 3x - 40 = 0

generation solution to a quadratic equation

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 3

c = -40

x = (-3 ± sqrt(3² - 4×1×-40))/(2×1) =

= (-3 ± sqrt(9 + 160))/2 = (-3 ± sqrt(169))/2 =

= (-3 ± 13)/2

x1 = (-3 + 13)/2 = 10/2 = 5

x2 = (-3 - 13)/2 = -16/2 = -8

negative values for a length do not make sense, so x = 5 is our solution

5.

Intersecting Chords Theorem

(x+1)×4 = (x-1)×5

4x + 4 = 5x - 5

9 = x

The difference is StartFraction x squared + 3 x minus 12 Over (x + 3) (x minus 5) (x + 7) EndFraction.

Answer:

The Circumference is 150.7 inches

Step-by-step explanation:

The cricumference of a circle is given by the formula:

[tex]C = 2\pi r[/tex]

We are given the radius and are given 3.14 for pi.

Substituting these values into the euation gives us:

C = 2(3.14)(24)

C = (6.28)×(24) = 150.72

The Circumference is 150.7 inches to the nearest tenth.

Answer: The circle's circumfrence is 18.84

Step-by-step explanation:

When you are finding the circumference of a circle you use the formula

[tex]C=2\pi r[/tex]

[tex]C=2*3.14*3[/tex]

[tex]C=18.84[/tex]

The true solution of the logarithmic equation [tex]\ln e^{\ln x} + \ln e^{\ln x^2} = 2\ln 8[/tex] will be 4.

Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.

The logarithmic equation is given as

[tex]\ln e^{\ln x} + \ln e^{\ln x^2} = 2\ln 8[/tex]

We know that the formula

[tex]\ln e = 1\\\\\ln b^a = a \ln b\\\\\ln a + \ln b= \ln a +b[/tex]

Then we have

[tex]\begin{aligned} \ln x \times \ln e + \ln x^2 \times \ln e = \ln 8^2\\\\\ln x + \ln x^2 = \ln 64\\\\\ln x*x^2 = \ln 64 \end{aligned}[/tex]

Then take antilog, then we get

[tex]\rm x^3 = 64\\\\x^3 = 4^3 \\\\x \ =4[/tex]

Answer:

  10 units wide; 24 units long

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

  2w+4 = 2(10) +4 = 24 . . . length

The positive solution to this equation is the one of interest here.

The width of the rectangle is 10 units; its length is 24 units.

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]

Step-by-step explanation:

The probality of getting a 3 on a die is ⅙ since they is only one 3 on the 6 sided die. So that will mean there is a 1 in 6 chance to get a 3.

Then the probability of getting tails on a coin is ½ because a coin on has 2 sides.

The probability of getting the 3 on the die and a tail on a coin will be the probability of getting the 3 on the die times the probability of getting the tails on the coin.

Answer

23

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.

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:

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.
