if cos x =1/5 , then what is the positive value of tan 1/2x, in simplest radical form with a rational denominator?

Answers

Answer 1

Answer: the positive value of tan(1/2x) in simplest radical form with a rational denominator is √(2/3).

Step-by-step explanation:

Using the half-angle formula for tangent, we have:

tan(1/2x) = ±√((1-cos(x))/(1+cos(x)))

Substituting cos(x) = 1/5, we get:

tan(1/2x) = ±√((1-1/5)/(1+1/5))

= ±√(4/6)

= ±√(2/3)

Since we are looking for the positive value, we have:

tan(1/2x) = √(2/3)

Therefore, the positive value of tan(1/2x) in simplest radical form with a rational denominator is √(2/3).

Answer 2

Answer:

Step-by-step explanation:

sin(x)=sqrt(24)/5=2*sqrt(6)/5

tan(x/2)=sin(x)/(1+cos(x))

Thus, tan(x/2)=sqrt(6)/3

Question The variables y and x have a proportional relationship, and y = 9 when x = 2. What is the value of y when x = 3? Enter your answer as a decimal in the box.

Answers

Answer:

13.5

Step-by-step explanation:

If y and x have a proportional relationship, we can write this relationship as:

y = kx

where k is the proportionality constant.

To find the value of k, we can use the information that "y = 9 when x = 2":

9 = k(2)

Solving for k, we get:

k = 9/2

Now we can use this value of k to find the value of y when x = 3:

y = (9/2)(3) = 27/2 = 13.5

Therefore, the value of y when x = 3 is 13.5.

B. 1/2sec(2pi) = 1/2

C. 2sec(pi/2) = does not exist

D. 2csc(pi/2) = 1

So, since at pi there is a vertical asymptote it should not exist. So, A or C.

Then pick x = 0, y must be 2.

A. sec(0) +2 = 1+2 = 3

se inscribe un cuadrado de lado 20 dm en una circunferencia. Determina el área sombreada que se muestra en la figura

Answers

Note that where you have a square with a side of 20dm is inscribed in a circle, the area of the shaded region is At = [tex]\approx[/tex] 257.08dm²

What is the rationale for the above response?

A square is a geometrical shape with four equal sides and four equal angles, each measuring 90 degrees.

In the figure we will determine the area of the shade:

The formula is given as follows:

1/2(Area of the Square) + ∡AB + ∡DC

Note that the above equation subsists because:

i)  the shaded region comprises of two congruent or similar triangles since the diagonals of a Square will bisect each other equally creating 4 congruent triangles.

ii) A square in a circle will always create 4 equal Chords.

Thus, imputing the figures we have:
(20dm)²/2 + [π ((20√2)/2)² - (20dm)²]/4

= 200 + [200π -400]/4
= 200 + (50π -100)

ical from a point 1.75m grove the ground and lom awa Laway from a Eleve tower the angle of of the top of the tower is to calculate the height of the tower​

Answers

The height of the tower is 17.32 meters

What is height and distance?

Height is the measurement of an item in the vertical direction, whereas distance is the measurement of an object in the horizontal direction from a certain location.

Given that, Ical is 10 meters away from a tower [since angle is not given let the angle of the top of the tower be 60°], we need to find the height of the tower, [see the figure attached]

The whole scene is making a right triangle, so using the concept of trigonometric ratios,

We get,

Tan 60° = height of the tower / distance of Ical from the tower

Tan 60° = height of the tower / 10

Height of the tower = 10 × Tan 60°

Height of the tower = 10 × √3

Height of the tower = 10√3

Height of the tower = 10 × 1.73

Height of the tower = 17.32

Hence, the height of the tower is 17.32 meters

You are selling flowers for a school fundraiser. When you purchase them, roses cost $3.50 and daisies cost $1.25. You have $300 to purchase flowers.
You sell 150 flowers total.

Answers

Answer:

So, if we sell 150 flowers total, we can purchase 100 daisies and 50 roses for exactly $300.

Step-by-step explanation:

Let R be the number of roses and D be the number of daisies.

Now we can set the following equations to represent the cost and the total number of flowers,

Cost equation=3.50R + 1.25D

                       = 300

Number of flowers equation= R + D

                                              = 150

We need to find the number of roses and daisies that we can purchase, as according to question the total number of flowers is 150. To find R, we can put value of  the number of flowers in the equation for R in terms of D, and also put this expression for R in the cost equation,

R = 150 - D

3.50R + 1.25D

= 300

3.50(150 - D) + 1.25D

= 300

525 - 3.50D + 1.25D

= 300

-2.25D = -225

D = 100

Therefore, we can buy 100 daisies and the remaining 50 flowers must be roses.

The cost of 100 daisies is 100 × 1.25

= $125

The cost of 50 roses is 50 × 3.50

= $175.

Therefore, the total cost is $125 + $175

= $300.

So, if we sell 150 flowers total, we can purchase 100 daisies and 50 roses for exactly $300.

In preparing to construct a one-sample t interval for a population mean, suppose we are not sure if the population distribution is Normal. In option (c) A boxplot of the data has a large outlier, we would not be safe constructing the interval based on an SRS of size 24 from the population.

What is a sample?

A sample is characterised as a more manageable and compact version of a bigger group. A smaller population that possesses the traits of a bigger group. When the population size is too big to include all participants or observations in the test, a sample is utilised in statistical analysis.

Constructing a one-sample t interval for a population mean is generally safe when the population is not Normal, as long as the sample size is large enough (usually at least 30) or the sample is taken from a population that is not too skewed or has outliers.

Therefore, options (a), (b), and (e) suggest that the sample may come from a population that is roughly Normal or can be transformed to be Normal, and so constructing the interval based on an SRS of size 24 would be safe.

Option (d) suggests that the sample standard deviation is large, but this does not necessarily mean that constructing the interval would not be safe.

It may reduce the precision of the interval, but as long as the sample size is sufficient, the interval can still be constructed.

Option (c) suggests that the sample has a large outlier, which may significantly affect the distribution of the sample and the calculation of the interval.

Therefore, in this circumstance, constructing the interval based on an SRS of size 24 would not be safe.

The three side lengths of four triangles are given. Which triangle is a right triangle? Triangle 1: 13‾‾‾√ 13 , 6, 7 Triangle 2: 7, 8, 13 Triangle 3: 10, 11, 12 Triangle 4: 10‾‾‾√ 10 , 9, 8

Answers

The triangle whose sides are √13, 6, and 7, is a right triangle.

What is the right triangle?

A right triangle is defined as a triangle with one right angle or two perpendicular sides. The longest side of a right triangle is called the hypotenuse.

Pythagorean Theorem :

The square on the hypotenuse is equal to the total of the squares on the legs of a right triangle.

Mathematically, let r be the length of the hypotenuse of a right triangle. Again let p, q be the lengths of other sides of this triangle. By the Pythagorean Theorem,

r² = p² + q².

How to solve this problem?

We just check which triangle's sides follow the above theorem.

Option A (Triangle with sides √13, 6, and 7 ):

13 + 36 = 49

i.e. (√13)² + 6² = 7²

This triangle's sides follow the Pythagorean Theorem.

So, the triangle with sides √13, 6, and 7 is a right triangle.

Option B (Triangle with sides 7, 8, and 13 ):

49 + 64 ≠ 169

i.e. 7² + 8² ≠ 13²

This triangle's sides do not follow the Pythagorean Theorem.

So, the triangle with sides 7, 8, and 13 is not a right triangle.

Option C (Triangle with sides 10, 11, and 12 ):

100 + 121 ≠ 144

i.e. 10² + 11² ≠ 12²

This triangle's sides do not follow the Pythagorean Theorem.

So, the triangle with sides 10, 11, and 12 is not a right triangle.

Option D (Triangle with sides √10, 9, and 8 ):

10 + 64 ≠ 81

i.e. (√10)² + 8² ≠ 9²

This triangle's sides do not follow the Pythagorean Theorem.

So, the triangle with sides √10, 9, and 8 is not a right triangle.

Therefore the triangle whose sides are √13, 6, and 7, is a right triangle. So, option A is correct.

Describe Graph?

In mathematics, a graph is a visual representation of a set of objects and the relationships between them. Graphs are widely used in many areas, including mathematics, computer science, engineering, social sciences, and more.

A graph consists of two main components: vertices (also known as nodes) and edges. The vertices represent the objects, and the edges represent the connections or relationships between them. The edges can be directed or undirected, meaning they can be one-way or two-way relationships.

There are many types of graphs, including:

Undirected graphs: Graphs in which edges have no direction.

Directed graphs: Graphs in which edges have a direction, often represented by arrows.

Weighted graphs: Graphs in which edges have weights or values, representing some kind of numerical data.

Bipartite graphs: Graphs in which the vertices can be divided into two distinct sets, with edges only connecting vertices in different sets.

Complete graphs: Graphs in which every vertex is connected to every other vertex by an edge.

Graphs are used to model and analyze various kinds of data, such as social networks, transportation systems, financial transactions, and more. They are also used in algorithms and data structures, such as shortest path algorithms and tree data structures. In addition, graphs are often visualized using software tools to help people better understand complex relationships and patterns in data.

Sam writes down the numbers 1, 2, 3, ..., 9999.

(a) How many digits did Sam write, in total?

(b) Sam chooses one of the digits written down, at random. What is the probability that Sam chooses a 0?

(c) What is the sum of all the digits that Sam wrote down?

Answers

Therefore, Sam wrote a total of 38,789 digits. Therefore, the probability that Sam chooses a 0 is approximately 0.026. So the sum of all the digits in the numbers from 1000 to 9999 is: 4500.

What is probability?

In mathematics, probability is a measure of the likelihood or chance of an event occurring. It is a way of quantifying uncertainty and expressing how likely it is that a particular outcome will occur. Probability is calculated by dividing the number of outcomes that satisfy a certain condition (such as rolling a six) by the total number of possible outcomes. Probability theory is used in a wide range of fields, including mathematics, statistics, physics, engineering, economics, and social sciences. It is used to model and analyze random phenomena, make predictions, and estimate the likelihood of certain outcomes.

Here,

(a) Sam writes down all the positive integers from 1 to 9999, inclusive. To find the total number of digits Sam wrote, we can count the number of digits in each number and add them up.

Numbers from 1 to 9 have one digit each, so there are 9 numbers with one digit, for a total of 9 digits.

Numbers from 10 to 99 have two digits each, so there are 90 numbers with two digits, for a total of 180 digits.

Numbers from 100 to 999 have three digits each, so there are 900 numbers with three digits, for a total of 2700 digits.

Numbers from 1000 to 9999 have four digits each, so there are 9000 numbers with four digits, for a total of 36000 digits.

Adding up these totals gives:

9 + 180 + 2700 + 36000 = 38789

Therefore, Sam wrote a total of 38,789 digits.

(b) Since Sam chose the digits 1 to 9999, there are 4 digits (0, 1, 2, and 3) that can appear in the thousands place, and 10 digits (0 to 9) that can appear in each of the other three places.

Therefore, the probability of choosing a 0 at random is the number of times 0 appears in the numbers divided by the total number of digits written down.

0 appears as the last digit in 1000 numbers (from 10 to 9990), and as the first digit in 9 numbers (1000, 10000, 2000, 20000, 3000, 30000, 4000, 40000, and 5000). So the total number of times 0 appears is 1000 + 9 = 1009.

The total number of digits Sam wrote is 38,789, so the probability of choosing a 0 at random is:

1009/38789 ≈ 0.026

Therefore, the probability that Sam chooses a 0 is approximately 0.026.

(c) We can find the sum of all the digits Sam wrote by adding up the sum of the digits in each number from 1 to 9999.

The sum of the digits in the numbers from 1 to 9 is 1+2+3+4+5+6+7+8+9=45.

The sum of the digits in the numbers from 10 to 99 can be found by observing that each of the digits from 0 to 9 appears in the tens place the same number of times (that is, 10 times each). Since there are 90 two-digit numbers, each digit appears a total of 10 x 90 = 900 times in the tens place. So the sum of the digits in the tens place is:

900(0+1+2+3+4+5+6+7+8+9) = 45,000

Similarly, each of the digits from 0 to 9 appears in the hundreds place the same number of times (that is, 100 times each). So the sum of the digits in the hundreds place is:

100(0+1+2+3+4+5+6+7+8+9) = 4500

Finally, each of the digits from 0 to 9 appears in each of the four places (thousands, hundreds, tens, and ones) the same number of times (that is, 1000 times each). So the sum of all the digits in the numbers from 1000 to 9999 is: 4500.

2. $6500 principal earning 2.8% compounded monthly ... after 2 years

Answers

Answer: To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

A = the amount of money after the given time period

P = the principal (starting amount)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period (in years)

In this case, the principal is $6500, the annual interest rate is 2.8% (or 0.028 as a decimal), and the interest is compounded monthly (so n = 12). We want to find the amount after 2 years, so t = 2.

Plugging these values into the formula, we get:

A = 6500(1 + 0.028/12)^(12*2)

A ≈ $7,107.08

Therefore, the amount of money after 2 years is approximately $7,107.08.

Total paper required = total surface area

Surface area of a cuboid = 2[(l×b) + (l×h) + (b×h)],

Where 'l' is the length, 'b' is the breadth and 'h' is the height

For the box, total surface area = 2[(8×3) + (3×2) + (8×2)]

=2[24 + 6 + 16]

Part B using mathematical reasoning explain why the other three equations are incorrect.


Pazzi how many total jerseys in Ms Chen purchase. SHOW YOUR WORK


Answer:______ Shirts

Answers

The equation that can be used to find x, the number of jerseys is 82.49 = 15.70x + 3.99

The other three equations are incorrect because the equation should be represented by total cost equals cost of each shirt multiplied by number of jerseys plus shipping cost.

Ms Chen purchased 15 jerseys.

How to write equations?

Cost of x jerseys including shipping = $82.49

Cost of shipping = $3.99

Cost of each jersey = $15.70

82.49 = 15.70x + 3.99

82.49 - 3.99 = 15.70x

78.50 = 15.70x

x = 78.50 / 5

x = 5

In conclusion, the number of jerseys bought is 5.

el area total de la figura que se muestra es 192cm²
¿cual es el valor de x?​

Answers

Answer:

x es igual a 8.

Step-by-step explanation:

The rectangle shown has a length of 0.9 centimeters and a width of 0.4 centimeters. A circle is drawn inside that touches the rectangle at two points. Which is closest to the area of the shaded region of the rectangle? Responses 0.14 cm2 0.23 cm2 0.28 cm2 0.49 cm2

Answers

The area of the shaded region of the rectangle is 0.23 cm², and option 2 is the correct answer.

What are complex figures?

The combined shapes of one or more simple polygons and circles make up the area of the composite shapes. We can add or subtract the areas of all the fundamental shapes together to determine the area of the composite shapes. Simply calculate the area of each individual form to obtain the area of composite shapes.

The length of the rectangle is 0.9 cm.

The width of the rectangle is 0.4 cm.

The diameter of the circle us 0.4 cm, thus the radius = 0.4/2 = 0.2 cm.

The area of the rectangle is:

A = (l)(b)

Substituting the values:

A = (0.9)(0.4)

A = 0.36 sq. cm.

The area of the circle is:

A = πr²

A = (3.14)(0.2)²

A = 0.1256 sq. cm.

The area of the shaded portion is:

Area of shaded portion = area of rectangle - area of circle

Area of shaded portion = 0.36 - 0.1256 = 0.2344 sq. cm

Hence, the area of the shaded region of the rectangle is 0.23 cm², and option 2 is the correct answer.

ricky took out a $258,000, 20-year mortgage at an APR of 3.84%.

what is the monthly payment?

what will be his total interest charges after 20 years?

Answers

The total monthly payment of Ricky with an APR of 3.84 % is given by the equation M = $ 1,208.0523

What is Annual Percentage Yield?

The annual percentage yield (APY) is the real rate of return earned on an investment, taking into account the effect of compounding interest. An APR is a number that represents the total yearly cost of borrowing money, expressed as a percentage of the principal loan amount.

The monthly payment [tex]M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1][/tex]

where

M = Total monthly payment

P = The total amount of your loan

I = Your interest rate, as a monthly percentage

N = number of months for paying off your mortgage

Given data ,

Let the monthly payment be represented as M

Now , the number of years n = 20 years

The annual interest rate i = 3.84 %

The total loan amount P = $ 258,000

Now , the monthly payment [tex]M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1][/tex]

On simplifying , we get

[tex]M = 258,000 [ ( \frac{ 0.0384}{12} ) ( 1 + \frac{ 0.0384}{12} )^{12*30} ] / [ ( 1 + \frac{ 0.0384}{12} )^{12*30} - 1 ][/tex]

[tex]M = 258,000 [ (0.0032 ) ( 1.0032 )^{360} ] / [ ( 1.0032 )^{360} - 1 ][/tex]

On further simplification , we get

M = 258,000 [ 0.0101078417 ] / [ 2.158700543922579 ]

M = 258,000 ( 0.00468237327729 )

M = $ 1,208.0523

Hence , the monthly payment of Ricky is $ 1,208.0523

the graph of f(x)=cos(x) is transformed into a new function, g(x), by stretching it horizontally by a factor of 6 and shifting it 5 units down. what is the equation of the new function g(x)?

Answers

Answer:

To stretch the graph of f(x) horizontally by a factor of 6, we can multiply the x-values of each point on the graph by 1/6. This will make the curve wider and flatter. The equation of the transformed function will be of the form:

g(x) = cos((1/6)x)

To shift the graph of g(x) 5 units down, we can subtract 5 from the y-values of each point on the graph. The final equation of the transformed function will be:

g(x) = cos((1/6)x) - 5

So, the equation of the new function g(x) is g(x) = cos((1/6)x) - 5.
