Find The Measure Of The Exterior Angle.

Answers

Answer 1

The measure of the exterior angle is 139 degrees.

What is the measure of the exterior angle?

The sum of the interior angle of a triangle is 180 degree.

The sum of angles on a straight line is 180 degrees.

From the diagram;

Angle 1 = 64 degreesAngle 2 = 75 degreesAngle 3 = ?

First, we determine the third interior angle of the triangle.

Angle 1 + Angle 2 + Angle 3 = 180

64 + 75 + Angle 3 = 180

139 + Angle 3 = 180

Angle 3 = 180 - 139

Angle 3 = 41 degrees

Now, angle 3 and the exterior angle forms a angle on a straight line.

Hence;

Angle 3 + Exterior angle = 180

41 +  Exterior angle = 180

Exterior angle = 180 - 41

Exterior angle = 139 degrees.

Therefore, 139 degrees is the exterior angle.

OPTION 1: Political Factions
In his Farewell Address in 1796, George Washington gave the following warnings about the dangers of political
parties:
"[Parties always] distract the public councils and (weaken] the public administration. It agitates the community with ill-
founded jealousies and false alarms, kindles the animosity of one party against another, [encourages) occasionally riot
and insurrection. It opens the door to foreign influence and corruption, which finds access to the government itself
through the channels of party passions..."
QUESTION: Why did George Washington caution against the formation of political parties?
What potential risks do political parties pose towards democracy? Do you think that the
country should have followed his advice?

Answers

Answer of the why did George Washington caution against the formation of political parties?

What potential risks do political parties pose towards democracy? Do you think that the country should have followed his advice are as follows :  

(a) He believes that the government was undermined by differences between the political parties. Additionally, he argues that "the alternate domination" of one party over another and concurrent attempts to exact revenge on their rivals have resulted in terrible atrocities and "is itself a frightful despotism."

(b)The democratic theory's main tenet is that democracies force administrations to take citizens' preferences into account. Every contemporary democracy is organized by political parties, and some observers contend that parties are what makes democracies responsive. Others, however, contend that parties give extremists a platform and make governments less receptive to the needs of the populace. As newly established democracies around the world grapple with concerns of representation and governability, the discussion of parties and democracy assumes fresh prominence.

Given arithmetic sequence:

12, 18, 24, ...

The first term of the given sequence is 12.

The common difference can be found by subtracting the first term from the second term:

[tex]\implies d=a_2-a_1=18-12=6[/tex]

Therefore:

a = 12d = 6

To find the sum of the first 200 terms, substitute n = 200, a = 12 and d = 6 into the formula:

[tex]\begin{aligned}S_{200}&=\dfrac{1}{2}(200)[2(12)+(200-1)(6)]\\&=100[24+(199)(6)]\\&=100[24+1194]\\&=100[1218]\\&=121800\end{aligned}[/tex]

Given geometric sequence:

12, 18, 27, ...

The first term of the given sequence is 12.

The common ratio can be found by dividing the second term by the first term:

[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{18}{12}=1.5[/tex]

Therefore:

a = 12r = 1.5

To find the sum of the first 8 terms, substitute n = 8, a = 12 and r = 1.5 into the formula:

[tex]\begin{aligned}\implies S_{8}&=\dfrac{12(1-1.5^8)}{1-1.5}\\\\&=\dfrac{12\left(1-\frac{6561}{256}\right)}{-0.5}\\\\&=\dfrac{12\left(-\frac{6305}{256}\right)}{-0.5}\\\\&=\dfrac{-\frac{18915}{64}}{-0.5}\\\\&=\dfrac{18915}{32}\\\\&=591.09375\end{aligned}[/tex]

Given geometric sequence:

[tex]\dfrac{1}{12},\dfrac{1}{18},\dfrac{1}{27},...[/tex]

The first term of the given sequence is ¹/₁₂.

The common ratio can be found by dividing the second term by the first term:

Answer:

equation: (x -1)²/64 -(y -4)²/80 = 1foci: (-11, 4), (13, 4)

Step-by-step explanation:

You want the steps to finding the equation of the hyperbola with center (1, 4), vertices (-7, 4) and (9, 4) and that includes the point (-11, -6).

Equation of a hyperbola

The standard-form equation of a hyperbola with center (h, k) and semi-axes 'a' and 'b' is ...

  [tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex]

The "linear eccentricity" 'c' is the distance from the center to a focus, and satisfies the equation ...

  c² = a² +b²

The vertices are (h±a, k) and the foci are (h±c, k).

Application

The center of the hyperbola is given as (1, 4). The distance from the right vertex to the center is ...

  a = 9-1 = 8

The equation thus far is ...

  (x -1)/8² -(y -4)/b² = 1

The value of 'b' can be determined from the given point:

  (-11 -1)²/8² -(-6 -4)²/b² = 1

  9/4 -100/b² = 1

  5/4 = 100/b²

  b² = 100/(5/4) = 80

The linear eccentricity is ...

  c² = a² +b²

  c² = 64 +80 = 144

  c = √144 = 12

The foci are (1±12, 4) = (-11, 4) and (13, 4).

The equation is ...

  (x -1)²/64 -(y -4)²/80 = 1

Step summaryThe given information was used to find semi-major axis 'a'. Together with the given center value (h, k), and the given point, the equation was written and solved for b².The value of 'c' was found from a² and b², and used to find the locations of the foci.

Answer:

[tex]\dfrac{(x-1)^2}{64}-\dfrac{(y-4)^2}{80}=1[/tex]

Center = (1, 4)Vertices = (-7, 4) and (9, 4)Foci = (-11, 4) and (13, 4)

Step-by-step explanation:

Standard equation of a horizontal hyperbola (opening left and right):

[tex]\boxed{\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1}[/tex]

where:

Center = (h, k)Vertices = (h±a, k)Co-vertices = (h, k±b)Foci = (h±c, k) where c² = a² + b²

Given:

Center = (1, 4)Vertices = (-7, 4) and (9, 4)Point on the hyperbola = (-11, -6)

Therefore:

h = 1k = 4

Find the value of a using the x-values of the vertices:

[tex]\begin{aligned}\implies h-a &= -7\\1-a &= -7\\a &= 8\end{aligned}[/tex]

[tex]\begin{aligned}\implies h+a &= 9\\1+a &= 9\\a &= 8\end{aligned}[/tex]

Therefore, a = 8.

Substitute the values of h, k and a into the formula:

[tex]\implies \dfrac{(x-1)^2}{8^2}-\dfrac{(y-4)^2}{b^2}=1[/tex]

[tex]\implies \dfrac{(x-1)^2}{64}-\dfrac{(y-4)^2}{b^2}=1[/tex]

Substitute the given point on the hyperbola (-11, -6) into the equation and solve for b²:

[tex]\implies \dfrac{(-11-1)^2}{64}-\dfrac{(-6-4)^2}{b^2}=1[/tex]

[tex]\implies \dfrac{(-12)^2}{64}-\dfrac{(-10)^2}{b^2}=1[/tex]

[tex]\implies \dfrac{144}{64}-\dfrac{100}{b^2}=1[/tex]

[tex]\implies \dfrac{144}{64}-1=\dfrac{100}{b^2}[/tex]

[tex]\implies \dfrac{144}{64}-\dfrac{64}{64}=\dfrac{100}{b^2}[/tex]

[tex]\implies \dfrac{80}{64}=\dfrac{100}{b^2}[/tex]

[tex]\implies \dfrac{5}{4}=\dfrac{100}{b^2}[/tex]

[tex]\implies b^2=\dfrac{4 \cdot 100}{5}[/tex]

[tex]\implies b^2=\dfrac{400}{5}[/tex]

[tex]\implies b^2=80[/tex]

Therefore, the equation of the hyperbola is:

[tex]\boxed{\dfrac{(x-1)^2}{64}-\dfrac{(y-4)^2}{80}=1}[/tex]

To find the foci, first find c where c² = a² + b²:

[tex]\implies c=\sqrt{a^2+b^2}[/tex]

[tex]\implies c=\sqrt{64+80}[/tex]

[tex]\implies c=\sqrt{144}[/tex]

[tex]\implies c=12[/tex]

Substitute the found value of c, along with the values of h and k into the foci formula:

[tex]\implies (h+c, k)=(1+12, 4)=(13,4)[/tex]

[tex]\implies (h-c,k)=(1-12,4)=(-11,4)[/tex]

Therefore, the foci are (-11, 4) and (13, 4).

The vertices of a rectangle are located at the coordinates (1, 4), (1, 5), (6, 5), and (6, 4). Find the length of the sides of the rectangle and its perimeter.

Answers

Answer: This is a 1 by 5 rectangle

perimeter = 12 units

========================================================

Work Shown:

Label the vertices A,B,C,D

A =  (1, 4)

B = (1, 5)

C = (6, 5)

D = (6, 4)

The x coordinates of points A and B are the same (x = 1). The difference in y values of these points is 5-4 = 1 unit. This is the height of the rectangle. In other words, it's the length of segment AB.

Points B and C have the same y coordinate (y = 5). The difference in x value is 6-1 = 5 which is the horizontal length of the rectangle. This is the length of segment BC.

In short, this is a 1 by 5 rectangle. It's one unit tall and five units across.

--------

Perimeter = 2*(length+width)

Perimeter = 2*(5+1)

Perimeter = 2*6

Perimeter = 12 units

Or you can add up the four sides (1,5,1 and 5) to get the same result.

Answers

The probability that three cards have the same number, using the hypergeometric distribution, is of:

0.0448 = 4.48%.

What is the hypergeometric distribution formula?

The probability mass function for the hypergeometric distribution is defined as follows:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters of the function are listed below:

x is the number of successes in the sample.N is the size of the population.n is the size of the sample.k is the total number of desired outcomes in the population.

In the context of this problem, the values of these parameters are given as follows:

N = 28, k = 4, n = 5, x = 3.

Hence for one color, the probability that three cards have the same number is:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 3) = h(3,28,5,4) = \frac{C_{4,3}C_{24,2}}{C_{28,5}} = 0.0112[/tex]

There are four colors, hence the probability is:

p = 4 x 0.0112 = 0.0448 = 4.48%.

-1/3 - 1/2

So to add/subtract fractions, the denominators have to be equal. We can change the -3/4 into -6/8 by just multiplying by 2/2 which is just 1. (Anything multiplied by 1 is just itself). So then we have:

-6/8x + 7/8x ---> 1/8x

Next, the second part.

Since neither denominators (3 or 2) can turn into one another by multiplying them with a number, we'll just multiply them with the opposite denominator.
So then we have:

-1/3 * (2/2) = -2/6
-1/2 * (3/3) = -3/6

-2/6 - 3/6 = -5/6

So finally we have:

1/8x - 5/6

The Wilson family had 8 children. Assuming that the probability of a child being born a girl is 0.5, find the probability that the Wilson family had: at least 3 girls
how do I do this problem

Answers

The probability that the family had at least 3 girls is 0.6367

How to determine the probability that the family had at least 3 girls?

This is a binomial probability experiment. We are going to use the binomial distribution formula for determining the probability of x successes:

P(x = r) = nCr . p^r . q^n-r

Given: n= 8, probabibility of sucess (p) = 0.5, x≥3 (at least 3 girls)

The failures can be calculated using q = 1 - p = 1 - 0.5 = 0.5

P(x≥3) = 1 - P(x≤3) = 1 - ( P(x= 0) + P(x= 1) + P(x= 2) + P(x= 3) )

Using the formula:

P(x≥3)  = 1 - ( (8C0 x 0.5⁰  x 0.5⁸⁻⁰) +(8C1 x 0.5¹  x 0.5⁸⁻¹) + (8C2 x 0.5²  x 0.5⁸⁻²)  +  (8C3 x 0.5³  x 0.5⁸⁻³) )

          = 1 - ( (1/256) + (1/32) + (7/64) + (7/32) )

         = 0.6367

Therefore, the probability that the Wilson family had at least 3 girls is 0.6367

The answer please this is geometry, we’ve been trying to identify triangles by angles & sides

Answers

The measure of the required angle ∠VUT = 80 degrees

Given : A triangle with angle measures as :

∠RTU = 50°

exterior angle ∠UVR = 120°

To find : ∠VUT

In the given triangle we can use the exterior angle sum property

which states that the angle opposite to the inside of the triangle and the angle outside the triangle

The angle outside the triangle is 120 degrees

120 = ∠VUT  + 50

thus on subtracting 50 both sides we will get

∠VUT = 120 - 50

∠VUT = 80 degrees

Beth makes $10.25/hour and Bartley makes $11.50 an hour. If Beth worked for 23 hours and Bartley worked for 17 hours, what was their difference in the amount of money they each earned?

Answers

The difference in the amount of money earned by Beth and Bartley is $40.25.

Given that, Beth makes $10.25/hour and Bartley makes $11.50 an hour.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

If Beth worked for 23 hours

Money earned by Beth is

10.25×23=$235.75

If Bartley worked for 17 hours

Money earned by Bartley is

11.50×17 =$195.5

So, difference of money = 235.75-195.5

= $40.25

Hence, the difference in the amount of money earned by Beth and Bartley is $40.25.

1x(3x6)=18 create a equivalent multiplication sentence that illustrates the associative property of multiplication

Answers

The equivalent multiplication sentence that shows associative property is 3x(1×6)

What is associative property?

Associative property is defined as, when more than two numbers are added or multiplied, the result remains the same, irrespective of how they are grouped.

This means that if a,b,c are real numbers then a×(b×c)=b×(a×c)

using the associative property,1×(3×6)= 3×(1×6)

To verify the statement,let's find out

solving the parentheses first

1×(3×6)=1×18= 18

3×(1×6)= 3×6= 18

this means that 1×(3×6) and 3×(1×6) are associative

therefore 1×(3×6)=3×(1×6)

A concession stand at the Tennis Center sells a hamburger/drink combination dinner for $7. The profit, y (in dollars), can be approximated by
y=-0.001x² +
2+3.2x-400 where x is the number of dinners prepared.
(a) Find the number of dinners that should be prepared to maximize profit.
(h) What is the maximum profit?

Answers

The number of dinners that should be prepared to maximize profit is 1200.

The maximum profit is $1040

We know that,

y = ax²+ bx + c

The expression has the greatest value at x = -b/2a

From the question, we have

y=-0.001x² +2.4x-400

x = -b/2a

= -2.4/2*(-0.001)

=1200

substituting the value  we get

y=-0.001x² +2.4x-400

y=-0.001*1200² +2.4*1200-400

y=$1040

Multiplication:

Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis. Multiplication tables are the main use that is obvious. In mathematics, the repeated addition of one number in relation to another is represented by the multiplication of two numbers. These figures can be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, either m is added to itself 'n' times or the other way around.
