What Is The Simplest Form Of The Radical Expression Sqrt2+sqrt3/sqrt2-sqrt3please Show Work

Answers

Answer 1

Answer:

-5 - 2sqrt6

Step-by-step explanation:

To simplify (sqrt2+sqrt3)/(sqrt2-sqrt3), we can rationalize the denominator, which involves multiplying both the numerator and denominator by the conjugate of the denominator.

The conjugate of sqrt2-sqrt3 is sqrt2+sqrt3, so we can multiply both the numerator and denominator by sqrt2+sqrt3:

(sqrt2+sqrt3)/(sqrt2-sqrt3) * (sqrt2+sqrt3)/(sqrt2+sqrt3) = ((sqrt2+sqrt3)(sqrt2+sqrt3))/((sqrt2-sqrt3)(sqrt2+sqrt3))

Expanding the numerator and simplifying, we get:

(sqrt2+sqrt3)^2 / (sqrt2^2 - sqrt3^2)

= (2 + 2sqrt2sqrt3 + 3) / (2 - 3)

= (5 + 2sqrt6) / (-1)

= -5 - 2sqrt6

Therefore, (sqrt2+sqrt3)/(sqrt2-sqrt3) simplifies to -5 - 2sqrt6.

Answer 2

The simplest form of the expression (√2 + √3) / (√2 - √3) is - (5 + 2√6).

We have,

To simplify the expression (√2 + √3) / (√2 - √3), we can rationalize the denominator by multiplying both the numerator and the denominator by the conjugate of the denominator.

The conjugate of (√2 - √3) is (√2 + √3).

Multiplying the numerator and denominator by (√2 + √3), we get:

[(√2 + √3) x (√2 + √3)] / [(√2 - √3) x (√2 + √3)]

Expanding both the numerator and denominator:

[(√2 + √3)(√2 + √3)] / [√2 x √2 - √2 x √3 + √3 x √2 - √3 x √3]

Simplifying:

[2 + 2√2√3 + 3] / [2 - 3]

Combining like terms:

[5 + 2√6] / [-1]

Since the denominator is -1, we can multiply both the numerator and denominator by -1 to simplify further:

[5 + 2√6] / 1

Finally, we have:

(5 + 2√6)

Therefore,

The simplest form of the expression (√2 + √3) / (√2 - √3) is - (5 + 2√6).

How long, to the nearest year, will it take an investment to
double if it is continuously compounded at 18% per year?
_______ yr

Answers

It will take 4 years for an investment to double if it is continuously compounded at 18% per year.

The time it takes for an investment to double if it is continuously compounded at 18% per year can be calculated using the formula:
T = ln(2)/r

Where T is the time in years, ln(2) is the natural logarithm of 2, and r is the annual interest rate.

Substituting the given values into the formula, we get:
T = ln(2)/0.18
T ≈ 3.85 years

Therefore, to the nearest year, it will take approximately 4 years for the investment to double if it is continuously compounded at 18% per year.

When finding r round to the nearest hundredth. Deposit amount: $100; total deposits: 120; interest rate: 10%, compounded semi-annually

The value οf the annuity after 120 depοsits is $1,059,780.64.

What is cοmpοund interest?  

Cοmpοund interest is interest that is earned nοt οnly οn the principal amοunt but alsο οn any interest earned οn that principal amοunt οver time.

Tο determine the value οf the annuity, we can use the fοrmula fοr the future value οf an annuity:

[tex]A = P \times \dfrac{(1 + r/n)^{(nt)} - 1)}{(r/n)}[/tex]

where A is the future value οf the annuity, P is the mοnthly depοsit amοunt, r is the annual interest rate, n is the number οf times the interest is cοmpοunded per year, and t is the tοtal number οf depοsits.

In this case, P = $100, n = 2 (since interest is cοmpοunded semi-annually), t = 120, and r is the interest rate per year, sο we need tο find r. Tο dο this, we can use the fοrmula:

[tex]A = P\times (1 + r/n)^{(nt)[/tex]

where A is the future value of the annuity after t depοsits.

Substituting the given vaIues, we have:

[tex]\$100 \times (1 + r/2)^{(2\cdot120)[/tex] = A

SimpIifying, we get:

[tex](1 + r/2)^{240} = A/100[/tex]

Taking the natural lοgarithm of both sides, we get:

[tex]ln(1 + r/2)^{240} = ln(A/100)[/tex]

240*ln(1 + r/2) = ln(A/100)

ln(1 + r/2) = ln(A/100)/240

Solving for r, we get:

[tex]$r = 2 \times \frac{e^{(ln(A/100)}}{240) - 1}[/tex]

Substituting the given vaIues, we get:

r = 0.4902 or 49.02%

Now we can plug in all the values into the original fοrmula for the future value οf the annuity:

[tex]A = $100\times \dfrac{(1 + 0.4902/2)^{(2\cdot 120) - 1)}}{0.4902/2}[/tex]

SimpIifying, we get:

A = $1,059,780.64

Therefοre, the value οf the annuity after 120 depοsits is $1,059,780.64.

a. What is 6%of 34 ? b. 17 is what percent of 34 ? c. 18 is30%of what number? d. What is 7% of 49 ? 8. Copy the number line and fill in the blank so that each tick mark is

Answers

a) 6% of 34 is 2.04
b) 17 is 50% of 34

c) 18 is 30% of 60

d) 7% of 49 is 3.43.

a. To find 6% of 34, you can multiply 34 by 0.06 (which is the decimal equivalent of 6%): 34 * 0.06 = 2.04. So 6% of 34 is 2.04.

b. To find what percent 17 is of 34, you can divide 17 by 34 and then multiply by 100 to convert the decimal to a percentage: (17/34) * 100 = 50%. So 17 is 50% of 34.

c. To find what number 18 is 30% of, you can divide 18 by 0.30 (which is the decimal equivalent of 30%): 18 / 0.30 = 60. So 18 is 30% of 60.

d. To find 7% of 49, you can multiply 49 by 0.07 (which is the decimal equivalent of 7%): 49 * 0.07 = 3.43. So 7% of 49 is 3.43.

Answers

The cοst fοr οne οf each item is:

Candle: $1.625

Licοrice stick: $0.975

Candy: $2.50

What is an equatiοn?

In mathematics, an equatiοn is a statement that asserts the equality οf twο expressiοns, typically separated by an equals sign (=). The expressiοns οn either side οf the equals sign are called the left-hand side (LHS) and the right-hand side (RHS) οf the equatiοn.

Let's use variables tο represent the cοst οf each item. Let c be the cοst οf a candle and l be the cοst οf a licοrice stick, and let y be the cοst οf a candy.

Frοm the given infοrmatiοn, we can set up twο equatiοns tο represent the tοtal cοst fοr each persοn:

2c + l = 3.25 (Equatiοn 1)

y + 4l = 2.50 (Equatiοn 2)

We can then sοlve fοr each variable by using algebraic manipulatiοn.

Frοm Equatiοn 1, we can isοlate l by subtracting 2c frοm bοth sides:

l = 3.25 - 2c

We can substitute this expressiοn fοr l intο Equatiοn 2, and sοlve fοr y:

y + 4(3.25 - 2c) = 2.50

y + 13 - 8c = 2.50

y = 2.50 - 13 + 8c

y = 8c - 10.5

Nοw we can substitute the expressiοn fοr y and the expressiοn fοr l intο a single equatiοn tο sοlve fοr c:

2c + (8c - 10.5) = 3.25 + 2.5

10c - 10.5 = 5.75

10c = 16.25

c = 1.625

Sο a candle cοsts $1.625. We can use this value tο find the cοst οf a licοrice stick:

l = 3.25 - 2c

l = 3.25 - 2(1.625)

l = 0.975

Sο a licοrice stick cοsts $0.975. Finally, we can find the cοst οf a candy using the expressiοn we fοund earlier:

y = 8c - 10.5

y = 8(1.625) - 10.5

y = 2.5

Sο a candy cοsts $2.50.

Therefοre, the cοst fοr οne οf each item is:

Candle: $1.625

Licοrice stick: $0.975

Candy: $2.50

Find the future value of this loan. $17,592 at 6.6% interest for
8 months
The future value of the loan is _______________
​(Round to the nearest cent as​ needed.)

Answers

The future value of the loan is $18,358.16. This means that after 8 months, the loan will have grown to $18,397.54 due to the interest.

To find the future value of this loan, we can use the formula FV = PV(1 + r)^t, where FV is the future value, PV is the present value, r is the interest rate, and t is the time period in years.

In this case, we have PV = $17,592, r = 6.6%, and t = 8 months or 0.667 years (8/12).

Plugging these values into the formula, we get:
FV = $17,592(1 + 0.066)^0.667
FV = $17,592(1.066)^0.667
FV = $18,358.16

Therefore, the future value of the loan is $18,358.16. This means that after 8 months, the loan will have grown to $18,397.54 due to the interest.

What is general transformations?

A transformation is a procedure that involves either changing an object's orientation to create an image or expanding or reducing its size to create a new one.

We'll use the given point (4, -10) as the input for each transformation, and apply the transformation to find the new location of the point.

a. f(x) = (x + 2) - 3

f(4) = (4 + 2) - 3 = 3

Therefore, the new location of the point under the transformation f(x) = (x + 2) - 3 is (3, -10).

b. f(x) = 2(x - 4) - 1

f(4) = 2(4 - 4) - 1 = -1

Therefore, the new location of the point under the transformation f(x) = 2(x - 4) - 1 is (-1, -10).

c. f(x) = -1/3x

f(4) = -1/3(4) = -4/3

Therefore, the new location of the point under the transformation f(x) = -1/3x is (-4/3, -10).

d. f(x) = (2/3)x + 2

f(4) = (2/3)(4) + 2 = 8/3 + 2 = 14/3

Therefore, the new location of the point under the transformation f(x) = (2/3)x + 2 is (14/3, -10).

In each case, the image of the point is the new location after applying the transformation.

a. Image: (3, -10)

b. Image: (-1, -10)

c. Image: (-4/3, -10)

d. Image: (14/3, -10)

The mean waiting time is:

Answers

The mean waiting time for these customers is 18.33 minutes.

The mean waiting time can be calculated by multiplying each waiting time by its frequency, summing up these products, and then dividing by the total number of customers.

In mathematical terms, the mean waiting time is:

Mean = (x1 * f1 + x2 * f2 + ... + xn * fn) / (f1 + f2 + ... + fn)

Where x1, x2, ..., xn are the waiting times, and f1, f2, ..., fn are the corresponding frequencies.

Using the data from the table, we can plug in the values and calculate the mean waiting time:

Mean = (5 * 2 + 10 * 4 + 15 * 6 + 20 * 8 + 25 * 10) / (2 + 4 + 6 + 8 + 10)

Mean = (10 + 40 + 90 + 160 + 250) / 30

Mean = 550 / 30

Mean = 18.33 minutes

11x-10+80=180 solve for x

Answers

Answer:

To solve for x, we need to isolate it on one side of the equation by performing inverse operations.

11x - 10 + 80 = 180

First, we combine the constant terms on the left side of the equation:

11x + 70 = 180

Next, we isolate the variable term by subtracting 70 from both sides:

11x = 110

Finally, we solve for x by dividing both sides by 11:

x = 10

Therefore, the solution to the equation 11x - 10 + 80 = 180 is x = 10.

11X=180+10-80

Answers

The algebraic equation "4x = 22.2 - 1.9" could be used to find the price of one tire patch.

What is the algebraic equation?

Mathematical equations with one or more variables and algebraic operations like addition, subtraction, multiplication, division, exponentiation, and roots are known as algebraic equations. By identifying the values of the unknown variables that fulfill the equation, these equations can be used to illustrate mathematical connections between variables and to solve issues.

Although algebraic equations can take many different forms, they often require utilizing the equal sign (=) to make one expression equal to another. For instance, the algebraic equation x + 2 = 7 shows the connection between the constants 2 and 7 and the unknown variable x.

The equation that could be used to find the price of one tire patch is:

4x = 22.2 - 1.9

This equation represents the total cost of the four tire patches (4x) subtracted from the initial balance on Rhyan's gift card ($22.20) and the remaining balance after the sale ($1.90).

Simplifying the equation, we get:

4x = 20.3

Dividing both sides by 4, we get:

x = 5.075

So the price of one tire patch is $5.075.

Therefore, the equation "4x = 22.2 - 1.9" could be used to find the price of one tire patch. None of the other equations listed would lead to the correct answer.

(C) What is the probability of getting, k , k> = 0, k <= 5, red balls and (k-5) black balls?
.......................................................................................

Answers

A) The probability of at least one red ball being obtained is 1 - the probability of no red balls being obtained.

The probability of no red balls being obtained is (7/17)*(6/16)*(5/15)*(4/14)*(3/13) = 0.0096. Therefore, the probability of at least one red ball being obtained is 1 - 0.0096 = 0.9904.

B) The probability of two red balls and three black balls being obtained is (10/17)*(9/16)*(7/15)*(6/14)*(5/13) = 0.0909. The probability of one red ball and four black balls being obtained is (10/17)*(7/16)*(6/15)*(5/14)*(4/13) = 0.0216.
C) The probability of getting k red balls and (5-k) black balls is (10 choose k)*(7 choose (5-k))/(17 choose 5). This can be calculated for each value of k from 0 to 5 and summed to find the total probability.

For example, when k=0, the probability is (10 choose 0)*(7 choose 5)/(17 choose 5) = 0.0096. When k=1, the probability is (10 choose 1)*(7 choose 4)/(17 choose 5) = 0.0909. The total probability is the sum of these individual probabilities.

The game of Yahtzee is played with five fair dice. The goal is to roll certain hands', such as Yahtzee (all five dice showing the same number) or a full house (three of a kind and two of a kind). In the first round of a player's turn, the player rolls all five dice. Based on the outcome of that roll, the player has a second and third round, where he/she can then choose to re-roll any subset of the dice to get a desired hand. (a) What is the probability of rolling a Yahtzee on the first round? (b) Suppose that, on the second round, the dice are (2,3, 4,6,6). You decide to re-roll both sixes in the third round. What is the probability that you roll either a small straight or a large straight (a large straight is where all five dice are in a row)?

Answers

a) The probability of rolling a Yahtzee is 0.00077

b) The probability of rolling either a small straight or a large straight is 0.1389

Given data:

(a)

To calculate the probability of rolling a Yahtzee on the first round, we need to determine how many outcomes correspond to a Yahtzee and divide it by the total number of possible outcomes when rolling five dice.

A Yahtzee occurs when all five dice show the same number. There are 6 possible outcomes (each number from 1 to 6), and each outcome has only 1 way of occurring. So, there are 6 ways to roll a Yahtzee.

The total number of possible outcomes when rolling five dice is 6^5 (since each die has 6 sides).

Probability of rolling a Yahtzee = (Number of Yahtzee outcomes) / (Total number of outcomes)

[tex]= \frac{6} {6^5}[/tex]

≈ 0.00077 (rounded to 5 decimal places)

(b)

In the second round, you have (2, 3, 4, 6, 6). In the third round, you choose to re-roll both sixes.

A small straight is when you have four consecutive numbers among the dice (e.g., 1, 2, 3, 4, or 2, 3, 4, 5, or 3, 4, 5, 6).

There are three possible small straights: (2, 3, 4, 5), (3, 4, 5, 6), and (1, 2, 3, 4). Each of these outcomes has only one way of occurring.

A large straight is when all five dice are in a row (e.g., 1, 2, 3, 4, 5 or 2, 3, 4, 5, 6).

There are two possible large straights: (1, 2, 3, 4, 5) and (2, 3, 4, 5, 6). Each of these outcomes has only one way of occurring.

Total favorable outcomes (small straights + large straights) = 3 + 2 = 5

Total number of possible outcomes when re-rolling two dice = 6^2 = 36

Probability of rolling either a small straight or a large straight = (Number of favorable outcomes) / (Total number of outcomes)

[tex]=\frac{5}{36}[/tex]

≈ 0.1389 (rounded to 4 decimal places)

Hence, the probability that you roll either a small straight or a large straight after re-rolling the dice is approximately 0.1389.

Frequency polygon question: work out the upper and lower bonds

Answers

They are not the same as the upper and lower limits used in other statistical calculations.

what are statistical data?

A accumulation of numerical data that has been methodically gathered, arranged, and examined is referred to as statistical data. Numerous phenomena, including economic patterns, demographic traits, health outcomes, and more, are described and measured using this data. Numerous techniques, such as surveys, experiments, observations, and administrative documents, can be used to gather statistical data. After being gathered, the data can be examined statistically to reveal patterns, connections, and trends that can be used to guide policy development and decision-making.

given

This is a histogram showing the frequency distribution of the weights of 30 students. Each bar represents a weight range, and the height of the bar represents the frequency of students in that weight range.

To find the upper and lower boundaries for each weight range, we can use the following formula:

Lower bound = midpoint of the previous range + 0.5

Upper bound = midpoint of the current range - 0.5

For example, the lower bound of the first range (60-64) is:

Lower bound = midpoint of previous range + 0.5

= 57

Upper bound = midpoint of current range - 0.5

= 61.5

We can apply the same formula to find the upper and lower bounds for the other ranges in the histogram. The results are:

60-64: lower bound = 57, upper bound = 61.5

65-69: lower bound = 62, upper bound = 66.5

70-74: lower bound = 67, upper bound = 71.5

75-79: lower bound = 72, upper bound = 76.5

80-84: lower bound = 77, upper bound = 81.5

85-89: lower bound = 82, upper bound = 86.5

90-94: lower bound = 87, upper bound = 91.5

95-99: lower bound = 92, upper bound = 96.5

points F(2,6), G(2,-1). H(x,y) form a triangle in the xy -coordinate plane. if the area of this triangle is 14 square units, then which of the following are possible coordinates for point H?

Answers

The perpendicular line connecting points F and G results in the formation of a triangle with a 14 square unit surface area.

What does coordinate mean?

In mathematics, a coordinate is a set of numbers or symbols that describes an object's position or location in a geometric space. The most popular coordinate system is the Geographic coordinate system, which creates a grid on a surface or in three dimensions using a series of perpendicular lines. Each location on the plane or in space is then uniquely identified by an ordered pair or set of three numbers, respectively, that represent a point's distance from the origin along each of the coordinate system's axes.

Given that points F and G share the same x-coordinate, the line connecting them is perpendicular. A degenerate triangle with negative area will be formed by any point H that shares the same x-coordinate as F and G.

D = √((2-2)2 + (6-(-1),2) = √(49), which =  7.

distance(FH)/7  = 2/7.

distance(GH)/7  = 4/7

Distance(FH) / Distance(GH)  = 1 / 2.

The distance between any two points H(x, y) and F(2,6) or G(2,-1) can be calculated using the distance formula as follows:

distance(FH) is  =  √((x-2) + (y-6)).

Distance (GH) is  =  √((x-2) + (y+1)).

By changing the aforementioned values, we obtain:

√((x-2)**2**y+1**2)/7) = 4/7

(x-2)² + (y+1)² = 16

(x-2)² + (y-6) (y-6)² = 1/4 ((x-2)² + (y+1)²)

By condensing and extending, we obtain:

3(x-2)² + 13(y-6)² = 196

5(x-2)² + 25(y+1)² = 784

7(x-2)² + (y-6)² = 1

A triangle with a 14 square unit surface area is created when the perpendicular line joining F and G.

Find the y-intercept of line y=4/3*+2/3
Write your answer as an integer or as a simplified proper or improper fraction, not as an ordered pair.

Answers

Answer:

y = (4/3)x + 2/3

The y-intercept is the value of y when x is equal to zero. So we can substitute x = 0 into the equation and solve for y:

y = (4/3)(0) + 2/3 = 2/3
The y-intercept of the line y = (4/3)x + 2/3 is 2/3.

Step-by-step explanation:

Answer:

The y-intercept is (2/3)

Step-by-step explanation:

I will assume that the equation is missing the "x," and will rewrite is as:

 y = (4/3)x + (2/3)

This is in standard form of y = mx + b, where m is the slope and b is the y-intercept.

The slope is (4/3) and the y-intercept is (2/3)

Amy is attending a school orchestra concert.she sees her math teacher seated 10 meters ahead of her and her science teacher seated 24 meters to her right.How far apart are the two teachers?

Answers

Answer:

The two teachers are 26 meters apart. To calculate this, you can use the Pythagorean Theorem, which states that the distance between two points is equal to the square root of the sum of the squares of the differences between the coordinates of the two points. In this case, the coordinates of the math teacher are (10, 0) and the coordinates of the science teacher are (0, 24), so the distance between them is the square root of [(10-0)^2 + (0-24)^2] = √(100 + 576) = √676 = 26 meters.

We can use the Pythagorean theorem to solve this problem. Let's draw a diagram:

A (Amy)

/|

/ |10 meters

/____|

B C (science teacher)

We have a right triangle ABC, where AB = 10 meters and BC = 24 meters. We want to find the length of AC, which is the distance between the two teachers.

Using the Pythagorean theorem:

AC^2 = AB^2 + BC^2

AC^2 = 10^2 + 24^2

AC^2 = 676

AC = sqrt(676)

AC = 26 meters

Therefore, the two teachers are 26 meters apart.

According to the above, the statement that is true about the expression can be inferred: Since the factor of 5/6 is less than 1, the product of 8 * 5/6 will be less than 8. Additionally, the measure of the giant mouse would be 0.76 meters.

How to find the correct statement about fractions?

To find the correct statement about the fractions we must analyze each of the statements and check it according to the multiplication information. According to the above, we can establish that the factor of 5/6 is less than one because the division of these two numbers results in a number less than 1.

5 / 6 = 0.83

So each number that we multiply by this fraction will give a result less than the same number. In this case if we multiply 8 by this fraction it would give us 6.66

8 * 0.83 = 6.66

On the other hand, if we want to know the height of the giant mouse, we must establish what the size of the Chihuahua is. So we develop the fraction 2 1/3 = 2.33

To find the height of the giant mouse we must divide the height of the chihuahua by 3.
