Answer:

[tex]MN=18\ units[/tex]

Step-by-step explanation:

we know that

The Intersecting Chord Theorem, states that When two chords intersect each other inside a circle, the products of their segments are equal.

so

In this problem

[tex]AB*BD=MB*BN[/tex]

substitute

[tex](9)(x+1)=(x-1)(15)\\ \\9x+9=15x-15\\ \\15x-9x=9+15\\ \\ 6x=24\\ \\x=4\ units[/tex]

Find the length of line segment MN

[tex]MN=MB+BN=(x-1)+15=x+14[/tex]

substitute the value of x

[tex]MN=4+14=18\ units[/tex]

Answer:

MN = 18

Step-by-step explanation:

AD and MN are two chords intersecting inside the circle at point B.

As we know from intersecting chords theorem.

AB × BD = BN × BM

So 9(x-1)  = 15 (x-1)

9x + 9  = 15x - 15

15x - 9x = 15 + 9

6x = 24

x = 4

and MN = (x-1) + 15

             = (x + 14)

             = 4 + 14 ( By putting x = 4 )

             = (18)

Therefore, MN = 18 is the answer.

Answer:

d= 2

Step-by-step explanation:

To find the common difference, take the second term and subtract the first

-2 - (-4)

-2+4 = 2

We add 2 each time

Lets check

Take the third term and subtract the second

0- -2

0+2 =2

The common difference is 2

[tex]\huge{\boxed{\sqrt{65}}}\ \ \boxed{\text{approx. 8.06225775}}[/tex]

The distance formula is [tex]\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are the points.

Substitute in the values. [tex]\sqrt{(3-(-1))^2 + (-5-2)^2}[/tex]

Simplify the negative subtraction. [tex]\sqrt{(3+1)^2 + (-5-2)^2}[/tex]

Add and subtract. [tex]\sqrt{4^2 + (-7)^2}[/tex]

Solve the exponents. [tex]\sqrt{16 + 49}[/tex]

Add. [tex]\sqrt{65}[/tex]

[tex]65[/tex] has no square factors, so this is as simple as the answer can get. You can use a calculator to find that [tex]\sqrt{65}[/tex] is approximately [tex]8.06225775[/tex].

The formula for distance between two points is:

[tex]\sqrt{(x_{2} -x_{1})^{2} + (y_{2} -y_{1})^{2}}[/tex]

In this case:

[tex]x_{2} =3\\x_{1} =-1\\y_{2} =-5\\y_{1} =2[/tex]

^^^Plug these numbers into the formula for distance like so...

[tex]\sqrt{(3 -(-1))^{2} + (-5-2)^{2}}[/tex]

To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

First we have parentheses. Remember that when solving you must go from left to right

[tex]\sqrt{(3 -(-1))^{2} + (-5-2)^{2}}[/tex]

3 - (-1) = 4

[tex]\sqrt{(4)^{2} + (-5-2)^{2}}[/tex]

-5 - 2 = -7

[tex]\sqrt{(4)^{2} + (-7)^{2}}[/tex]

Next solve the exponent. Again, you must do this from left to right

[tex]\sqrt{(4)^{2} + (-7)^{2}}[/tex]

4² = 16

[tex]\sqrt{16 + (-7)^{2}}[/tex]

(-7)² = 49

[tex]\sqrt{(16 + 49)}[/tex]

Now for the addition

[tex]\sqrt{(16 + 49)}[/tex]

16 + 49 = 65

√65 <<<This can not be further simplified so this is your exact answer

Your approximate answer would be about 8.06

Answer:

Step-by-step explanation:

Use FOIL: (a + b)(c + d) = ac + ad + bc + bd

and i² = -1

(6 + i)(2 + 9i) = (6)(2) + (6)(9i) + (i)(2) + (i)(9i)

= 12 + 54i + 2i + 9i²

= 12 + 54i + 2i + 9(-1)

= 12 + 54i + 2i - 9               combine like terms

= (12 - 9) + (54i + 2i)

Answer: The sequence is: An = -2*8^(n-1)

Step-by-step explanation:

 geometric sequence is of the form:

An = a*r^(n-1)

where can be any positive integer number.

here the first two numbers are -2 and -16, so we have that:

A1 = a*r^(0) = a = -2

now, we know that our sequence is of the form:

An = -2*r^(n-1)

now, for n= 2 we have that:

A2 = -2*r^(1) = -2*r = -16

r = -16/-2 = 8

now we have determinated our sequence:

An = -2*8^(n-1)

b) [tex]\frac{11}{57}[/tex]

Step-by-step explanation:

We are given that a committee of three people is selected at random from a set of eight teachers, seven parents of students, and five alumni.

We are to find:

a) the probability the committee consists of all teachers is:

Number of ways to select three that are all teachers = [tex]8C3[/tex]

Number of ways to select three randomly = [tex]20C3[/tex]

P (3 all teachers) = [tex]\frac{8C3}{20C3}[/tex] = [tex]\frac{14}{285}[/tex]

b) the probability the committee has no teachers is:

Number of ways to select three that it has no teachers = [tex]12C3[/tex]

Number of ways to select three randomly = [tex]20C3[/tex]

P (no teachers) = [tex]\frac{12C3}{20C3}[/tex] = [tex]\frac{11}{57}[/tex]

Answer:

3^3 In scientific notation terms

Step-by-step explanation:

First let's look at this in a little more simple way

[tex]\frac{3^{-9}}{3^{-12}}[/tex]

there so know we can start,

First since the main number is 3, put that away to the side for now:

3<----------     [tex]\frac{-9}{-12}[/tex]

Then, we need to replace the / symbol or the fraction with a subtraction equation:

[tex]^{-9-(-12)}[/tex]

Next, we need to simplify:

[tex]^{-9 + 12}[/tex]

Then, simplify some more and you should get:

[tex]^{3}[/tex]

Finally, get back the original 3 and combine it with the smaller 3:

[tex]3^{3}[/tex]

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

d = - 85 - (- 92) = - 85 + 92 = 7 and a₁ = - 92, hence

Answer:

So you will want to graph the following 3 points:

(0,2)

(3,3)

(-3,1)

Then connect the points.

Step-by-step explanation:

So we have the equation x-3y=-6.

I'm going to solve for y once so I don't have to do it 3 times when choosing a value for x.

x-3y=-6

Subtract x on both sides:

 -3y=-x-6

Divide both sides by -3:

   [tex]y=\frac{-x}{-3}+\frac{-6}{-3}[/tex]

Simplify where you can:

  [tex]y=\frac{1}{3}x+2[/tex]

So since this in the slope-intercept form, y=mx+b where slope is m and b is y-intercept we have that (0,2) is on our line.  If you plug in 0, you will get 2 like this y=1/3 (0)+2=0+2=2.  

Now I'm going to choose easy values to plug in, ones that are divisible by 3 since x is being multiplied by 1/3.

So if x=3, then [tex]y=\frac{1}{3}(3)+2=1+2=3[/tex], so (3,3) is on the line.

So if x=-3, then [tex]y=\frac{1}{3}(-3)+2=-1+2=1[/tex]. so (-3,1) is on the line.

So you will want to graph the following 3 points:

(0,2)

(3,3)

(-3,1)

Answer: 150°

Step-by-step explanation:

In the given triangle ABC ∠A=70°, ∠C=80°

therefore ∠B=180-(∠A+∠C)=180-(70+80)  [sum angle property of triangle]

⇒∠B=30°

Now, heights(altitude) are drawn from vertices A and C on respective bases

they intersect at a point M. Also, we know that heights are perpendicular on the bases.

Also, point of intersection of altitudes is called orthocenter.

Now since M is orthocenter,    ∠ABC+∠AMC=180° (property of orthocenter in a triangle)

⇒30°+∠AMC=180°

⇒∠AMC=180°-30°=150°

Hence in the triangle ABC, ∠AMC=150°

Answer:

The length of the pool is 400 feet.

The width of the pool is 120 feet.

Step-by-step explanation:

We are given the width (W) is 30% of the length (L).

We are also given the perimeter of the pool is 1040.

So in equation form this is what we have:

W=.3L   (of means multiply)

2L+2W=1040

We are going to plug the first equation into the second like so:

2L+2(.3L)=1040

2L+.6L=1040

2.6L=1040

Divide both sides by 2.6

L=1040/2.6

L=400

The length of the pool is 400 feet.

W=.3L

W=.3(400)

W=120

The width of the pool is 120 feet.

We get two equations that we can use for this equation.

2w + 2L = 1040

and

w = 0.3L

We can input w into the first equation:

0.6L + 2L = 1040

2.6L = 1040

L= 400

W = 120

Answer:

Step-by-step explanation:

1) f(x) = |x| has its vertex at (0, 0), so the x-value is 0.

2) Cannot figure out what you meant by  \x{ + 3.

3) f(x) = 5x + 31 has a straight line graph, no vertex.

4)   [x] - 6 does not have a vertex, or at least not a well-defined one like |x|

5)  Unsure of what you meant by 5x + 31 - 6.  Did you mean 5x + 25?  This does not have a vertex.

1) Divide the numbers

6/22= 0.27 (27 is repeating)

2) Multiply the decimal by 100

0.2727(100)= 27.27

3) Round

27.27 is closer to 27

Therefore, 6/22 to the nearest whole number is 27%.

Hopefully this helps!

Answer: 27%

Step-by-step explanation:

Given the fraction [tex]\frac{6}{22}[/tex], you need to divide the numerator by the denominator in order to rewrite it as a decimal number.

 [tex]\frac{6}{22}=0.27[/tex]

Now, to express it in percentage, the final step is to multiply the decimal number by 100.

Therefore, you get that [tex]\frac{6}{22}[/tex] to the nearest whole percent is:

[tex](0.27)(100)=27\%[/tex]
