Answer:

We can use the half-angle formula for sine to find the exact value of sin(a/2) in terms of sin(a):

sin(a/2) = ±√[(1 - cos(a))/2]

where the ± sign depends on the quadrant of a/2.

To use this formula, we first need to find cos(a). We can do this using the identity:

sin^2(a) + cos^2(a) = 1

Substituting sin(a) = 7/9, we get:

(7/9)^2 + cos^2(a) = 1

Simplifying and solving for cos(a), we get:

cos(a) = ±4/9

Since a is in quadrant I, we take the positive value of cos(a):

cos(a) = 4/9

Now we can use the half-angle formula for sine to find sin(a/2):

sin(a/2) = ±√[(1 - cos(a))/2]

Substituting cos(a) = 4/9, we get:

sin(a/2) = ±√[(1 - 4/9)/2]

Simplifying, we get:

sin(a/2) = ±√(5/18)

Since a is in quadrant I, a/2 is also in quadrant I, so we take the positive value of sin(a/2):

sin(a/2) = √(5/18)

Therefore, the exact value of sin(a/2) is √(5/18)

In the circle , the value οf x is 50°.

A secant in geοmetry is a line that tοuches a curve at at least twο different pοints. The Latin wοrd secare, which means tο cut, is where the wοrd secant derives. A secant crοsses a circle at precisely twο pοints when it is a circle. A chοrd is the line segment that the twο pοints determine, i.e., the interval οn the secant whοse ends are the twο pοints.

Remember that a tangent line is οne that crοsses a circle at precisely οne pοint. The term "secant line" describes a line that passes thrοugh twο pοints οn a circle. Secant is a Latin wοrd that means "tο cut," and it is derived frοm secare. A chοrd is the line segment defined by the twο pοints where a secant tοuches a circle in a given space.

Here in the given circle using secant line fοrmula ,

Answer:

Step-by-step explanation:

We can use the market-to-book ratio to calculate the company's market price per share.

Market-to-book ratio = Market value per share / Book value per share

Book value per share = Shareholder equity / Number of shares outstanding

We are given the market-to-book ratio as 2.60, and the shareholder equity as R1000 000. We can calculate the book value per share as follows:

Book value per share = R1000 000 / Number of shares outstanding

To calculate the number of shares outstanding, we can use the earnings per share (EPS) formula:

EPS = Earnings / Number of shares outstanding

We are given the earnings per share as R2.50, and the earnings after interest and taxes as R600 000. Substituting these values, we get:

R2.50 = R600 000 / Number of shares outstanding

Solving for Number of shares outstanding:

Number of shares outstanding = R600 000 / R2.50 = 240,000 shares

Now, we can calculate the book value per share:

Book value per share = R1000 000 / 240,000 = R4.17 per share

Finally, we can calculate the market value per share using the market-to-book ratio:

Market-to-book ratio = Market value per share / Book value per share

2.60 = Market value per share / R4.17

Market value per share = 2.60 x R4.17 = R10.83 per share

Therefore, the company's market price per share is R10.83.

Answer:

Let's denote the duration of each episode of Lola's podcast by "L" and the duration of each episode of Franco's podcast by "F".

From the information given, we can write two equations based on the total duration of content for the two years:

17L + 43F = 5,645 (equation 1)

36L + 43F = 6,956 (equation 2)

To solve for L and F, we can eliminate F by subtracting equation 1 from equation 2:

(36L + 43F) - (17L + 43F) = 6,956 - 5,645

Simplifying, we get:

19L = 1,311

Therefore, the duration of each episode of Lola's podcast (L) is:

L = 1,311 / 19

L ≈ 69.0 minutes

To find the duration of each episode of Franco's podcast (F), we can substitute the value of L into either equation 1 or 2:

17L + 43F = 5,645

17(69.0) + 43F = 5,645

1,173 + 43F = 5,645

43F = 4,472

F = 4,472 / 43

F ≈ 104.0 minutes

Therefore, each episode of Lola's podcast is approximately 69.0 minutes long, and each episode of Franco's podcast is approximately 104.0 minutes long.

Answer:

To find the total surface area of the square pyramid, we need to find the area of each of its faces and add them up.

The pyramid has a square base with sides of 8 inches and each triangular face has an isosceles right triangle shape with two sides of 8 inches and a hypotenuse of 2 x 8 = 16 inches (using the Pythagorean theorem).

The total surface area is then:

Area of the square base: 8 x 8 = 64 square inches

Area of each triangular face: 1/2 x 8 x 8 = 32 square inches (since each triangle is isosceles with base and height of 8 inches)

Total surface area: 4 x 32 + 64 = 192 + 64 = 256 square inches

Therefore, the total surface area of the square pyramid is 256 in². So, the closest answer option is 256 in, 2.

Answer:

There is 5% of the juice left.

Step-by-step explanation:

We know that originally, the container had 80 oz of orange juice, this is 100% in our case.

Then we can write a relation:

80 oz = 100%

Now there are 4 ounces left, in the same way as before, we can write this as:

4 oz = X%

We want to find X%

First, let's write our equations:

4 oz = X%

80 oz = 100%

We can take the quotient between these two equations to get:

(4oz/80oz) = (X%/100%)

We need to solve this for X%, then we get:

(4oz/80oz)*100% = X% = 5%

This means that 4 oz is 5% of the initial volume of the juice container.

Then we can conclude that there is 5% of the juice left.

Answer: $28,383.68.

Step-by-step explanation:

The first step is to determine the number of monthly payments over the 5-year period, which is 5 years x 12 months/year = 60 months.

Next, we can use the formula for the future value of an annuity, which is:

FV = P * ((1 + r/n)^(n*t) - 1) / (r/n)

where:

FV is the future value of the loan (the amount owed at the end of the 5-year period)

P is the initial principal amount ($20,000 in this case)

r is the annual interest rate (6%)

n is the number of compounding periods per year (12 for monthly compounding)

t is the total number of years (5)

Plugging in these values, we get:

FV = $20,000 * ((1 + 0.06/12)^(12*5) - 1) / (0.06/12)

FV = $28,383.68

Therefore, the balance owed at the end of the 5-year period would be $28,383.68.

Answer:

Step-by-step explanation:

Ranking:

Compound the interest every month instead of every two months.

Increase the interest rate by 1%.

Let the account increase for one more year.

Increase the starting amount by $100.

Calculations:

If the interest is compounded monthly instead of every two months, the final value would be $1,357.36, which is an increase of $9.18 compared to the original value.

If the interest rate is increased to 6%, the final value would be $1,411.58, which is an increase of $63.40 compared to the original value.

If the account increases for one more year at the same interest rate, the final value would be $1,435.09, which is an increase of $86.91 compared to the original value.

If the starting amount is increased by $100, the final value would be $1,421.61, which is an increase of $73.43 compared to the original value.

This is because the tangent function approaches infinite when 2x is an odd multiple of [tex]\pi[/tex]/2,

The tangent function, on the other hand, has vertical asymptotes at odd multiples of [tex]\pi[/tex]/2.

So the vertical asymptotes of g(x) in the range of x = [-90°; 90°] are:

Examining the behavior of the tangent function as x approaches positive or negative infinity can reveal the horizontal asymptotes of the function g(x) = 3tan(2x).

As x approaches odd multiples of /2, the tangent function oscillates between positive and negative infinity, so no horizontal asymptotes exist.

As a result, in the given range, the formulae for the vertical asymptotes of the function g(x) = 3tan(2x) are:

Answer: Exponential & $11,709.83

Step-by-step explanation:

The growth of the investment can be represented by an exponential function because the interest is being compounded quarterly, which means that the interest is being added to the account balance and the account balance is growing exponentially over time.

The formula for the future value of an investment with continuous compounding is:

A = P e^(rt)

Where A is the future value, P is the principal investment, e is the mathematical constant approximately equal to 2.71828, r is the annual interest rate expressed as a decimal, and t is the time in years.

In this case, the principal investment is $10,000, the annual interest rate is 3.2%, and the interest is compounded quarterly, so the quarterly interest rate is 3.2%/4 = 0.8%. The time period is 5 years, so t = 5.

The formula for the future value of an investment with quarterly compounding is: A = P (1 + r/n)^(nt)

Where n is the number of compounding periods per year, which is 4 in this case.

Substituting the values, we get:A = $10,000 (1 + 0.032/4)^(4*5) = $11,709.83

Therefore, the value of the account after 5 years is $11,709.83 rounded to the nearest cent.

Answer:

Assuming that the expression is asking for the tangent of 1 radian, we can use the tangent half-angle formula to find an exact value:

tan(1) = 2tan(1/2) / (1 - tan^2(1/2))

To find tan(1/2), we can use the half-angle formula for tangent:

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

We cannot simplify this expression any further without a calculator. Therefore, the exact value of tan(1) is:

tan(1) = 2sin(1) / (cos(1) - cos^2(1) + 1)

Again, we cannot simplify this expression any further without a calculator.

For the second expression, we are asked to find the value of:

tan(arctan(6/4))

By definition, tan(arctan(x)) = x for all x, so we have:

tan(arctan(6/4)) = 6/4 = 3/2

Therefore, the exact value of the expression tan(6/4) is 3/2.

the correct option for this question is  (a) e < 53.

Why it is?

The inequality that represents Natasha's earnings, e, from any of the companies she interviewed with is:

e < 53.5

This is because her projected earnings per hour range from $25.13 to $53.5, and the maximum value is $53.5. So, her earnings from any of the companies cannot be greater than $53.5 per hour. Therefore, the correct answer is option (a) e < 53.

Earnings are the amount of money that a person earns from their work, business, investments, or other sources of income. This can include salaries, wages, commissions, bonuses, and profits, among others.

Earnings are typically reported as gross income, which is the total amount earned before taxes and other deductions are taken out. It is an important measure of a person's financial well-being and is often used to determine eligibility for credit or loans. Earnings can vary widely depending on a person's job, level of experience, education, and industry, among other factors.
