The answers to both questions are as:

(a) the value of the investment after 5 years is $14,917.95, after 10 years is $23,673.58, and after 15 years is $37,337.35,

b) the amount of the final payment is $688.32.

What is compound interest?

Compound interest is when you earn interest on both the money you've saved and the interest you earn.

We can use the formula for compound interest to solve this problem:

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

where A is the final amount, P is the principal (initial investment), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time (in years).

(a) For 5 years with semiannual compounding:

n = 2 (compounded semiannually)

r = 0.08 (8% annual rate)

t = 5

[tex]A = 9900(1 + 0.08/2)^{(2*5)}[/tex]

A = $14,917.95

(b) For 10 years with semiannual compounding:

n = 2 (compounded semiannually)

r = 0.08 (8% annual rate)

t = 10

[tex]A = 9900(1 + 0.08/2)^{(2*10)}[/tex]

A = $23,673.58

(c) For 15 years with semiannual compounding:

n = 2 (compounded semiannually)

r = 0.08 (8% annual rate)

t = 15

[tex]A = 9900(1 + 0.08/2)^{(2*15)}[/tex]

A = $37,337.35

Therefore, the value of the investment after 5 years is $14,917.95, after 10 years is $23,673.58, and after 15 years is $37,337.35, assuming the interest is compounded semiannually.

To calculate the final payment, we can first find the balance of the loan at the end of the fifth year, and then use this as the principal to calculate the balance at the end of the tenth year.

The interest rate is 5% per year, compounded quarterly. This means that the quarterly interest rate is:

r = 5% / 4 = 0.0125

Let B be the balance of the loan after 5 years. Then we have:

B = 1000*(1 + r)²⁰- 200*(1 + r)⁴

where the first term is the future value of the initial loan after 5 years, and the second term is the present value of the first payment of $200.

Plugging in the values, we get:

B = 1000*(1 + 0.0125)²⁰ - 200*(1 + 0.0125)⁴

B = 1000*(1.0125)²⁰ - 200*(1.0125)⁴

B = 1346.49

So the balance of the loan after 5 years is $1346.49. We can use this as the principal to calculate the balance at the end of the tenth year, which is the final payment we are looking for.

Let P be the final payment. Then we have:

P = 1346.49*(1 + r)⁴⁰ - 800*(1 + r)²⁰

where the first term is the future value of the balance after 10 years, and the second term is the present value of the second payment of $800.

Plugging in the values, we get:

P = 1346.49*(1 + 0.0125)⁴⁰ - 800*(1 + 0.0125)²⁰

P = 1346.49*(1.0125)⁴⁰ - 800*(1.0125)²⁰

P = 688.32

So the amount of the final payment is $688.32.

hence, the answers to both questions are as:

(a) the value of the investment after 5 years is $14,917.95, after 10 years is $23,673.58, and after 15 years is $37,337.35,

b) the amount of the final payment is $688.32.

The following sets of numbers could represent the three sides of a

triangle is {7, 15, 20}.

How to determine the set that represent the three sides of a triangle

The set of numbers {7, 15, 20} could represent the three sides of a triangle, but the other sets of numbers do not satisfy the triangle inequality theorem, which states that the sum of any two sides of a triangle must be greater than the third side. Checking the sets of numbers:

For {7, 15, 20}, 7 + 15 > 20, 7 + 20 > 15, and 15 + 20 > 7, so they satisfy the triangle inequality theorem and could represent the sides of a triangle.

For {7, 16, 23}, 7 + 16 < 23, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.

For {11, 22, 35}, 11 + 22 < 35, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.

For {5, 17, 22}, 5 + 17 < 22, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.

Therefore, the answer is {7, 15, 20}.

part e Theresa’s computer at home has 1 terabyte of storage. How many more bits of storage does her computer have than the combined bits available on her family’s phones, tablets, and cloud storage? Type your answer in scientific notation.

Answers

Answer:

Step-by-step explanation:

We need to convert the 1 terabyte into bits, which is:

1 terabyte = 1,000 gigabytes (GB) x 1,000 megabytes (MB) x 1,000 kilobytes (KB) x 1,000 bytes (B) x 8 bits (b)

1 terabyte = 1,000,000,000,000 bytes x 8 bits

1 terabyte = 8,000,000,000,000 bits

Let's assume the total storage of all the family's phones, tablets, and cloud storage is x bits. Then, the number of more bits of storage Theresa's computer has is:

8,000,000,000,000 bits - x bits

We are not given the value of x, so we cannot calculate the exact difference.

However, we can still express the answer in scientific notation by noting that:

8,000,000,000,000 = 8 x 10^12

So, the difference in bits of storage can be written as:

(8 x 10^12) - x bits

The Yellowstone National Park sits at an elevation of 8,000 to 11,000 feet above sea level. During the month of June, the temperature at 8,000 feet above sea level was recorded as 650 Fahrenheit, and, at a distance of 10,500 feet feet above sea level, the temperature was recorded as 15⁰ Fahrenheit. For every additional 100 feet above sea level, the temperature decreases by tº Fahrenheit, where t is a constant. What is the value of t?​

Answers

Answer:

Step-by-step explanation:

To find the value of t, we can use the information given about the temperature at two different elevations and use the formula for a linear equation.

Let's assume that the temperature decreases by tº Fahrenheit for every additional 100 feet above sea level, where t is the constant we want to find.

Then, using the two points given:

- (8000, 65) where 65 is the temperature in Fahrenheit at 8000 feet above sea level

- (10,500, 15) where 15 is the temperature in Fahrenheit at 10,500 feet above sea level.

We can calculate the slope of the line connecting these two points:

slope = (15 - 65) / (10,500 - 8,000) = -25

The slope of the line represents the amount that the temperature decreases per unit increase in elevation. In this case, we've found that the temperature decreases by 25 Fahrenheit for each increase in elevation of 1000 feet.

To find the value of t, we need to express the slope in terms of the decrease in temperature per 100 feet of elevation. We can do this by dividing the slope by 10:

t = slope / 10 = -2.5

Therefore, the value of t is -2.5.

Step-by-step explanation:

When we combine like terms, we get:

7x² +9x² - 6x² = (7+9-6)x² = 10x²

So the polynomial in standard form is 10x².

The degree of the polynomial is 2 (since the highest power of the variable x is 2) and the number of terms is 1 (since there is only one term). Therefore, we classify this polynomial as a quadratic monomial.

The polynomial in standard form is 7x² + 9x² - 6x². Combining like terms, we get 10x². This is a polynomial of degree 2 (since the highest exponent of the variable x is 2) and has only one term. So it’s a monomial.

Measure of the arc or angle indicated is 150.9 degrees.

Describe Arc?

In geometry, an arc is a portion of the circumference of a circle or any other curved shape. It is defined by two endpoints and all the points on the curve that lie between them. An arc is usually named by its two endpoints, with a small arc symbol above them to indicate that it is an arc.

The length of an arc can be calculated using the formula:

Arc length = (central angle/360) x 2πr

where r is the radius of the circle, and the central angle is the angle subtended by the arc at the center of the circle, measured in degrees.

The measure of an arc is the degree measure of the central angle subtended by the arc. A semicircle is an arc that subtends a central angle of 180 degrees, and a full circle is an arc that subtends a central angle of 360 degrees.

Since DE and PE are chords of the circle, and they intersect at point P, we can use the intersecting chords theorem to find the length of DP. Let x be the length of DP. Then:

DP * PE = DE * PC

x * (x + PE) = ([tex]\frac{CE}{2}[/tex]) * ([tex]\frac{CE}{2}[/tex])

x² + x(PE) - [tex]\frac{CE}{2}^{\frac{2}{4} }[/tex] = 0

Since angle DPE is 60 degrees, we can use the law of cosines to find PE. Let y be the length of PE. Then:

y² = DE² + DP² - 2 * DE * DP * cos(60)

y² = ([tex]\frac{CE}{2}[/tex])² + x^2 - ([tex]\frac{CE}{2}[/tex]) * x

Substitute this expression for y^2 into the equation for x and simplify:

[tex]x^{2} +x((\frac{CE}{2})^{2} + x^{2} -\frac{CE}{2} *x)^{0.5} -(\frac{CE}{2} ^{\frac{2}{4} } )=0[/tex]

Solve for x:

x = [tex]\frac{CE^{2} -4*(CE^{2} -3*\frac{CE}{2} ^{2} )^{0.5} }{4}[/tex]

x = [tex]\frac{3}{4} *\frac{CE^{2} }{CE^{2} -12}[/tex]

Now we can find the measure of the CD arc by using the formula for the central angle:

CD arc = [tex]2*arctan(\frac{DP}{CE})[/tex]

CD arc = [tex]2*arctan(\frac{x}{\frac{CE}{2} } )[/tex]

CD arc = [tex]2* arctan(CE^{2} -4*(CE^{2} -3*\frac{(\frac{CE}{2} ^{2})^{0.5}}{CE^{2}-12 } ))[/tex]

Simplifying this expression, we get:

[tex]CD arc=2*arctan(2*3^{\frac{1}{2} } -1)[/tex]

CD arc ≈ 150.9 degrees.

Measure of the arc or angle indicated in the given figure is 150.9 degrees.

Describe Arc?

In geometry, an arc is a portion of the circumference of a circle or other curved shape. It is defined by his two endpoints and all midpoints of the curve. Arcs are usually named after their two endpoints, with a small arc symbol above them to indicate that they are arcs.

Arc Length = (Center Angle/360) x 2πr

where r is the radius of the circle and the central angle is the angle the arc makes at the center of the circle, measured in degrees.

The arc measurement is the angle of the central angle defined by the arc. A half circle is an arc that spans a central angle of 180 degrees, and a full circle is an arc that spans a central angle of 360 degrees.

Since DE and PE are chords of the circle and intersect at P, we can use the chord rule to find the length of DP. Let x be the length of DP.  Then:

DP × PE = DE × PC

x × (x + PE) = (CE/2) × (CE/2)

x² + x(PE) - [tex]\frac{CE}{2} ^{\frac{2}{4} }[/tex] = 0

Since angle DPE is 60 degrees, we can use the law of cosines to find PE. Let y be the length of PE. Then:

y² = DE² + DP² - 2 × DE × DP × cos(60)

y² = ([tex]\frac{CE}{2}[/tex])² + x² -  ([tex]\frac{CE}{2}[/tex]) × x

Substitute this expression for y² into the equation for x and simplify:

[tex]x^{2} +x((\frac{CE}{2} ^{2}) + x^{2} - \frac{CE}{2}*x)^{0.5} -[/tex] [tex]\frac{CE}{2} ^{\frac{2}{4} }[/tex] = 0

Solve for x:

x = [tex]\frac{CE^{2} - 4*(CE^{2}-3*\frac{CE}{2} ^{2})^{0.5} }{4}[/tex]

x = (3/4) × (CE²/CE²-12)

Now we can find the measure of the CD arc by using the formula for the central angle:

CD arc = 2arc tan(DP/CE)

CD arc = 2arc tan [x/(CE/2)]

CD arc = 2arc tan (CE² - 4 × (CE² - 3 × [tex]\frac{(\frac{CE}{2} ^{2}) ^{0.5} }{CE^{2}-12 }[/tex] )

A,B and B,C form a right angle at point B. If A = (-3,-1) and B = (4,4), what is the equation of B,C?

Answers

Answer:

the equation of line BC is y = (-7/5)x + (48/5).

Step-by-step explanation:

To find the equation of the line that passes through points B and C, we first need to determine the coordinates of point C. Since the angle at B is a right angle, we can use the slope of line AB to find the slope of line BC.

The slope of line AB is:

mAB = (yB - yA) / (xB - xA)

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

= 5/7

Since lines AB and BC are perpendicular, the slope of line BC is the negative reciprocal of the slope of line AB:

mBC = -1 / mAB

= -7/5

Now we can use the point-slope form of the equation of a line to find the equation of line BC. We can use point B as the known point, since we already know its coordinates:

y - yB = mBC(x - xB)

Substituting the values we have:

y - 4 = (-7/5)(x - 4)

Expanding and simplifying:

y - 4 = (-7/5)x + (28/5)

y = (-7/5)x + (48/5)

Tο determine the value οf a variable representing an unknοwn quantity, equatiοns can be sοlved. A statement is nοt an equatiοn if there is nο "equal tο" symbοl in it. It will be regarded as an expressiοn.

Starting with the x terms:

[tex]x^2 - 10x[/tex]

Tο cοmplete the square, we need tο add and subtract [tex](10/2)^2 = 25:x^2 - 10x + 25 - 25[/tex]

Again, we need tο add and subtract [tex](18/2)^2 = 81:[/tex]

[tex]y^2 - 18y + 81 - 81[/tex]

This is nοw a perfect square:

[tex](y - 9)^2 - 81[/tex]

Therefοre, the expressiοn in standard fοrm is: [tex](x - 5)^2 + (y - 9)^2 = 101[/tex]

Glados has a savings account with $700 in it that earns 7.9% simple interest per year. How much money, to the nearest penny, will Glados have in 5 years?​

Answers

Answer:

To calculate the amount of money Glados will have in 5 years with simple interest, we can use the formula:

A = P(1 + rt)

where A is the final amount, P is the principal (initial amount), r is the annual interest rate as a decimal, and t is the time in years.

In this case, P = $700, r = 0.079 (since 7.9% is 0.079 as a decimal), and t = 5 years. Substituting these values into the formula, we get:

A = 700(1 + 0.079 x 5)

A = 700(1 + 0.395)

A = 700(1.395)

A = $976.50

Therefore, Glados will have $976.50 in 5 years, to the nearest penny.

Therefore, the probability that at least one of the next six births is a girl is 1 - 0.033 = 0.967 (rounded to three decimal places).

What is Probability?

Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain.

To calculate the probability of an event, you divide the number of ways that event can occur by the total number of possible outcomes. For example, if you flip a fair coin, there are two possible outcomes - heads or tails - and each has an equal probability of 0.5 (or 50%) of occurring.

Given by the question.

To find the probability that at least one of the next six births is a girl, we can find the probability that all six of them are boys and subtract it from 1.

The probability that one birth is a girl is 1 - 0.513 = 0.487.

The probability that all six births are boys is. [tex]0.513^{6}[/tex] = 0.033.

Geneva wants to save $12,000 to buy a new car. She just received an $8,000 bonus and plans to invest it in an account earning 7% Annual simple interest. How long will she need to leave her money in the account to accumulate the $12,000 she needs?

Answers

Answer:

7.14 years

Step-by-step explanation:

We can use the formula for simple interest to solve this problem:

Simple Interest = Principal x Rate x Time

where the principal is the initial investment, the rate is the annual interest rate, and the time is the number of years.

We know that Geneva wants to save $12,000, and she already has $8,000 from her bonus, so she needs to earn an additional $4,000 in interest. We can use this amount as the principal in the formula.

Simple Interest = $4,000

Principal = $8,000

Rate = 0.07 (7% expressed as a decimal)

Plugging in the values, we get:

$4,000 = $8,000 x 0.07 x Time

Simplifying, we get:

Time = $4,000 / ($8,000 x 0.07)

Time = 7.14 years (rounded to the nearest hundredth)

Therefore, Geneva will need to leave her money in the account for approximately 7.14 years to accumulate the $12,000 she needs

There is not enough evidence to support the analyst's claim that the stocks lost value from one hour to the next on that business day.

How to explain the hypothesis

The null hypothesis is that there is no significant difference between the two sets of prices, while the alternative hypothesis is that there is a significant difference.

Using a t-test calculator, we can find the t-value and p-value:

t-value = -0.322

p-value = 0.757

At a significance level of 0.01, the critical t-value with 6 degrees of freedom is ±3.707. Since the calculated t-value of -0.322 is within this range, we fail to reject the null hypothesis.

Therefore, there is not enough evidence to support the analyst's claim that the stocks lost value from one hour to the next on that business day.
