Answer 1

The exact value of sin θ is 9/13.

Option A is the correct answer.

We have,

In trigonometry,

The sine function (sin) represents the ratio of the length of the side opposite an angle in a right triangle to the length of the hypotenuse.

The cosecant function (csc) is the reciprocal of the sine function, meaning it is equal to 1 divided by the sine of an angle.

In this case,

We are given that csc θ (the cosecant of θ) is equal to 13/9.

To find the value of sin θ (the sine of θ), we can take the reciprocal of csc θ. So,

sin θ = 1/(csc θ) = 1/(13/9) = 9/13.

Therefore,

The exact value of sin θ is 9/13.

What is the value of x in the given triangle, in inches?

Answers

The numerical value of side length x in the right triangle is 8.

What is the numerical value of x?

The figures in the image are two similar right triagles.

Since the two right triangles are similar, we equate the ratio of the sides of the two triangles.

x/6 = (x + 4)/9

Cross multiply and solve for x:

6( x + 4 ) = x × 9

Apply distributive property:

6 × x + 6 × 4 = x × 9

Simplifying, we get:

6x + 24 = 9x

Subtract 6x from both sides:

6x - 6x + 24 = 9x - 6x

24 = 9x - 6x

24 = 3x

3x = 24

Divide both sides by 3:

100 tickets are sold for $1 each there is $25 prizes and a $10 prize what is the expected value for a person that buys a ticket round to the nearest cent

Answers

The expected value for a person buying a ticket is $0.35 rounded to the nearest cent.

What is the expected value for the person who buys the ticket?

The expected value is calculated considering the probabilities of winning each prize and the corresponding values of each prize.

Assuming:

P($25) as the probability of winning the $25 prize

P($10) as the probability of winning the $10 prize

There are 100 tickets sold, therefore, the probabilities can be found as follows:

P($25) = 1/100 (since there is only 1 $25 prize)

P($10) = 1/100 (since there is only 1 $10 prize)

The expected value (E), will then be:

E = P($25) * $25 + P($10) * $10

E = (1/100) * $25 + (1/100) * $10

E = $0.25 + $0.10

E = $0.35

There are approximately as many boys between 167 and 169 as there are between 169 and 170. True False

Answers

The statement that there are approximately as many boys between 167 and 169 as there are between 169 and 170 is false.

In statistics, understanding and interpreting data is an essential skill. One way to interpret data is by analyzing the distribution of values within a certain range.

To determine whether the statement is true or false, we need to analyze the distribution of boy's heights between the two ranges. Assuming the heights of boys are normally distributed, we can use the empirical rule, also known as the 68-95-99.7 rule, to estimate the percentage of boys within each range.

The empirical rule states that in a normal distribution:

68% of the values fall within one standard deviation of the mean

95% of the values fall within two standard deviations of the mean

99.7% of the values fall within three standard deviations of the mean

We can use this rule to estimate the percentage of boys within each range as follows:

Between 167 and 169: This range is one standard deviation below the mean. Therefore, approximately 68% of boys' heights fall within this range.

Between 169 and 170: This range is between one and two standard deviations below the mean. Therefore, approximately 27% of boys' heights fall within this range.

Based on this analysis, we can see that there are not approximately as many boys between 167 and 169 as there are between 169 and 170. In fact, there are significantly more boys between 167 and 169 than there are between 169 and 170.

The statement that there are approximately as many boys between 167 and 169 as there are between 169 and 170 is false.

Sarah wants to buy a new laptop. Store A is currently selling the laptop for $1,640 with an additional 20% off. Store B is selling the laptop for $1,500 with an additional 10% off. Which store offers a better deal?

Answers

Answer:

Store A

Step-by-step explanation:

If an item is 20% off, then you pay 80% of the price.

If an item is 10% off, then you pay 90% of the price.

Store A

80% of $1640 = 0.8 × $1640 = $1312

Store B

90% of $1500 = 0.9 × $1500 = $1350

Answer: Store A

Answer:

Store A

Step-by-step explanation:

Store A offers a 20% discount which is equivalent to 0.20 x $1,640 = $328.

The laptop is therefore sold for $1,640 - $328 = $1,312 at Store A.

Store B offers a 10% discount which is equivalent to 0.10 x $1,500 = $150.

The laptop is therefore sold for $1,500 - $150 = $1,350 at Store B.

Therefore, Store A offers a better deal at $1,312 compared to Store B at $1,350.

First we need to simplify the side lengths
Squared root of 21 is 4.58
Squared root of 85 is 9.22

Now the next step is to find the angle of N
We have the opposite and hypotenuse of angle N so we can use Sin

The equation for Sin is : opposite/hypotenuse

Since we are finding an angle we need to use sin of -1

Sin^-1 ( opposite / hypotenuse)
Sin ^1 (4.58/9.22) = about 30 degrees

Because we need to find cos we need the adjacent side length.
We can use the formula a^2 + b^2 = c^2
4.58^2 + b^2 = 9.22^2
B = 8


Plug in 30 degrees for the cos (n)
Cos = adjacent/ hypotenuse
Cos (30) = 8/9.22 = 0.87

Answers

The 91-day T-bill that Nadeen bought at an interest rate of 4.30% p.a. and face value of $5,000 indicates;

a) Nadeen paid about $4,946.24 for the T-bill

b) Barbara's selling price for the T-bill is about $4,962.74

What is a T-bill?

A Treasury bill (T-bill), is a short-term obligation that is issued by the U.S. Department of Treasury and which is backed by the United States government, and has a maturity of less than a year. T-bills are low risk investment as they are backed by the credit and full faith of the U.S. government.

The formula for the price of the T-bill can be calculated with the formula;

Price = Face Value/(1 + (Interest Rate × Days to Maturity/360))

Plugging in the value from the question, we get;

Price = 5000/(1 + (0.043 × 91/360)) ≈ 4946.24

Therefore, Nadeen paid $4,946.24 for the T-bill

b) The formula for the selling price can be presented as follows;

Selling Price = Face Value/(1 + (Interest Rate × Remaining Days to Maturity/360))

Plugging in the known values, we get;

Selling Price = 5,000/(1 + (0.053 × (91 - 40)/360)) ≈ $4,962.74

Therefore, Barbara sold the T-bill to her friend for $4,962.74

director, is also employed there.
Considering neither of them leaves their jobs,

Answers

Mrs. Bright has worked for 8 years, and Mr. Oswald has already worked for 24 years, which is more than Twice the number of years Mrs. Bright has worked.

The number of years Mrs. Bright has worked for the company. We know that Mr. Oswald has been in the company for 24 years, which is three times the number of years Mrs. Bright has worked.

So, Mrs. Bright has worked for 24 / 3 = 8 years in the company.

Now, let's find the number of years Mr. Oswald needs to work for the company to make it twice the number of years Mrs. Bright has worked.

Twice the number of years Mrs. Bright has worked is 2 * 8 = 16 years.

Since Mr. Oswald is already employed for 24 years, we need to find the additional years he needs to work to reach 16 more years.

16 more years - 24 years = -8 years.

The result of -8 years indicates that Mr. Oswald has already worked for more than twice the number of years Mrs. Bright has worked. Therefore, it is not possible for Mr. Oswald to work for more years in order to make it twice the number of years Mrs. Bright has worked.

An equilateral triangle has a perimeter of 36 inches. What is the height of the triangle? Express your answer as a simplified radical.

Answers

Answer: the height of the equilateral triangle is 6√3 inches.

Step-by-step explanation:

To find the height of an equilateral triangle, we can use the formula:

height = (√3/2) * side

In this case, we are given the perimeter of the triangle, which is 36 inches.

Since an equilateral triangle has three equal sides, each side would be 36 inches divided by 3, which is 12 inches.

Now we can substitute the side length into the formula:

height = (√3/2) * 12

Simplifying:

height = (√3/2) * 12

height = (√3 * 12)/2

height = (12√3)/2

height = 6√3

Therefore, the height of the equilateral triangle is 6√3 inches.

HELP???

Answers

The approximate height difference between the birdhouse and the tree house is 3 ft.

It is less than the approximate difference in height between the swing set and the tree house.

How to find the approximate height difference between the birdhouse and the tree house?

A fraction represents the parts of a whole or collection of objects e.g. 3/4 shows that out of 4 equal parts, we are referring to 3 parts.

We have:

height of birdhouse = 14[tex]\frac{9}{16}[/tex] ft

height of tree house = 11[tex]\frac{13}{16}[/tex] ft

Thus, the approximate height difference between the birdhouse and the tree house will be:

14[tex]\frac{9}{16}[/tex] ft - 11[tex]\frac{13}{16}[/tex]  = 2[tex]\frac{3}{4}[/tex] ft

                   = 2.75 ft

                  = 3 ft

To determine if it is greater than or less than the approximate difference in height between the swing set and the tree house, we have to find the approximate difference in height between the swing set and the tree house. That is:

height of swing set = 8[tex]\frac{1}{4}[/tex] ft

height of tree house = 11[tex]\frac{13}{16}[/tex] ft

difference = 11[tex]\frac{13}{16}[/tex] - 8[tex]\frac{1}{4}[/tex]

                    = 3[tex]\frac{1}{2}[/tex]

                    = 3.5

Answers

The expected value of the car 7 years after it was purchased is $47,029.12.

To solve this problem, we need to calculate the expected value of the car after 7 years. To do this, we need to use the formula for calculating the value of a depreciating asset:

Value after n years = Initial Value - (Initial Value × (Depreciation Rate/100)×n)

In this case, the initial value of the car is $54792, the depreciation rate is 19%, and n = 7. Thus, the expected value of the car 7 years after it was purchased is:

Value after 7 years = 54792 - (54792 × (19/100)×7)

Value after 7 years = 54792 - (54792 × 0.19×7)

Value after 7 years = 54792 - 7762.88

Value after 7 years = $47,029.12

Therefore, the expected value of the car 7 years after it was purchased is $47,029.12.

Question 5 Joy is a 52-year-old nurse who earns a salary of R286 500 per annum. She contributes 7% of her annua salary to a pension fund. She only has her 2 daughters listed as a dependents on her medical aid. Sh is concerned that the R4000 monthly income tax deduction is too much.​

Answers

Determine Joy's annual income tax liability. If the amount is significantly different from the R4000 monthly deduction, she may need to consult a tax advisor to ensure accurate tax planning.

To assess whether the monthly income tax deduction of R4000 is too much for Joy, we need to calculate her annual income tax liability and compare it to the deduction.

First, let's calculate the amount Joy contributes to her pension fund annually:

Pension fund contribution = 7% of annual salary

Pension fund contribution = 7/100 * R286,500

Pension fund contribution = R20,055

Next, we need to determine Joy's taxable income by subtracting her pension fund contribution from her annual salary:

Taxable income = Annual salary - Pension fund contribution

Taxable income = R286,500 - R20,055

Taxable income = R266,445

Now, we can calculate the income tax liability based on the South African income tax brackets for the 2023 tax year. Please note that tax brackets are subject to change, so it's essential to verify with the latest tax regulations.

According to the current tax brackets, the tax rates for the 2023 tax year are as follows:

18% on the first R216,200 of taxable income

26% on the portion of taxable income between R216,201 and R337,800

31% on the portion of taxable income between R337,801 and R467,500

36% on the portion of taxable income between R467,501 and R613,600

39% on the portion of taxable income above R613,601

Using these tax rates, we can calculate the income tax liability:

Tax liability = (18% * amount within first bracket) + (26% * amount within second bracket) + (31% * amount within third bracket) + (36% * amount within fourth bracket) + (39% * amount within fifth bracket)

First, let's calculate the amounts within each tax bracket:

Amount within first bracket = min(Taxable income, R216,200)

Amount within second bracket = min(max(Taxable income - R216,200, 0), R337,800 - R216,201)

Amount within third bracket = min(max(Taxable income - R337,800, 0), R467,500 - R337,801)

Amount within fourth bracket = min(max(Taxable income - R467,500, 0), R613,600 - R467,501)

Amount within fifth bracket = max(Taxable income - R613,600, 0)

Now, let's substitute the values and calculate the income tax liability:

Tax liability = (18% * min(Taxable income, R216,200)) + (26% * min(max(Taxable income - R216,200, 0), R337,800 - R216,201)) + (31% * min(max(Taxable income - R337,800, 0), R467,500 - R337,801)) + (36% * min(max(Taxable income - R467,500, 0), R613,600 - R467,501)) + (39% * max(Taxable income - R613,600, 0))

By calculating this equation, you can determine Joy's annual income tax liability. If the amount is significantly different from the R4000 monthly deduction, she may need to consult a tax advisor to ensure accurate tax planning.

Answer:

(x - 3)² + (y + 4)² = 29

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

we have the coordinates of the centre but require to find the radius r

the radius is the distance from the centre to a point on the circle.

using the distance formula to find r

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

with (x₁, y₁ ) = (3, - 4 ) centre and (x₂, y₂ ) = (8, - 2) point on circle

r = [tex]\sqrt{(8-3)^2+(-2-(-4))^2}[/tex]

  = [tex]\sqrt{5^2+(-2+4)^2}[/tex]

  = [tex]\sqrt{25+2^2}[/tex]

  = [tex]\sqrt{25+4}[/tex]

  = [tex]\sqrt{29}[/tex]

then equation with centre (3, - 4 ) and r = [tex]\sqrt{29}[/tex] , is

(x - 3)² + (y - (- 4) )² = ([tex]\sqrt{29}[/tex] )² , that is

(x - 3)² + (y + 4)² = 29


Y varies directly as x, and y=9 when x = 27

Answers

If y varies directly as x, when x = 15, the value of y is equal to 5.

If y varies directly as x, we can express this relationship using the formula y = kx, where k is the constant of proportionality.

Given that y = 9 when x = 27, we can substitute these values into the equation:

9 = k x 27

To solve for k, we divide both sides of the equation by 27:

k = 9 / 27

k = 1/3

Now that we know the value of k, we can use it to find y for any other value of x.

Let's find y when x = 15:

y = (1/3) x 15

y = 5

Therefore, when x = 15, y is equal to 5.

You deposit $5000 in an account earning 6% interest compounded monthly. How much will you have in the
account in 15 years?

Answers

Answer:

$12270.46

----------------------

Use the compound interest formula:

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

Where:

A = final amount;P = initial deposit = $5000;r = annual interest rate = 6%;n = number of times the interest is compounded per year = 12;t = time period in years = 15.

Plugging in the values, we get:

A = 5000(1 + 0.06/12)¹²*¹⁵ A = 12270.46

2/5 of Jim's savings is equal to 4/9 of Max's savings. Jim has $30 more than Max. 5 How much money does Max have?​

Answers

As Jim has $30 more than Max, as per this, Max has $270.

Let's assume Max's savings as 'x' dollars.

We have:

2/5 of Jim's savings is equal to 4/9 of Max's savings.

(2/5) * Jim's savings = (4/9) * Max's savings

We also know that Jim has $30 more than Max.

Jim's savings = Max's savings + $30

So,

(2/5) * Jim's savings = (4/9) * Max's savings

(2/5) * (Max's savings + $30) = (4/9) * Max's savings

To solve for Max's savings, we can solve this equation:

(2/5) * (x + $30) = (4/9) * x

So, for x:

(2/5) * (x + $30) = (4/9) * x

Multiplying both sides by 45 (the least common denominator of 5 and 9) to eliminate the fractions:

18(x + $30) = 20x

18x + 540 = 20x

540 = 20x - 18x

540 = 2x

x = 270

Therefore, Max has $270.

(b) Write down the coordinates of BTS-4.

Answers

a. Jason will receive the strongest signal from BTS-4 because he is located in the Voronoi cell of BTS-4.

b. The coordinates of BTS-4 are (−8,4).

How to explain the information

a. Jason will receive the strongest signal from BTS-4 because he is located in the Voronoi cell of BTS-4. A Voronoi cell is a region of space that is closer to a given point than any other point. In this case, the given point is BTS-4. The Voronoi diagram is a partitioning of the plane into Voronoi cells, one for each point.

b. The edge connecting vertices P and Q has the equation y=4, which means that it is a horizontal line that intersects the y-axis at 4. The coordinates of BTS-2 are (−8,6), which means that it is located 8 units to the left of the origin and 6 units above the origin. Therefore, BTS-4 must be located 8 units to the left of the origin and 4 units above the origin, which gives it the coordinates (−8,4).

  - Blank

From the given information, we can deduce the following:

- Angle 1 is congruent to the angle formed by z and t (corresponding angles).

- Angle (10x + 5) degrees is congruent to angle 65 degrees (alternate interior angles).

- Angle (4x - 7) degrees is congruent to angle 2 (alternate interior angles).

Therefore, we can set up the following equations:

65 = 10x + 5     (Equation 1)

2 = 4x - 7       (Equation 2)

Solving Equation 1:

65 - 5 = 10x

60 = 10x

x = 6

Substituting x = 6 into Equation 2:

2 = 4(6) - 7

2 = 24 - 7

2 = 17

Hence, the measure of angle 2 is 17 degrees.

Therefore, the correct answer is:Angle 2 = 17 degrees.
