Scenario The Height, In Feet, Of An Object Shot Upwards Into The Air With An Initial Velocity, In Feet

Answers

Answer 1

1. An equation for the height of the rocket after t seconds is h(t) = -16t² + 320t.

2. The time it takes for the rocket to reach a height of 0 is 20 seconds.

The time it takes to reach the top of its trajectory is 10 seconds.

The maximum height is 1,600 feet.

The time it takes to reach a height of 800 feet is 2.9 or 17.1 seconds.

How to determine the time when the rocket would hit the ground?

Based on the information provided, we can logically deduce that the height (h) in feet, of this rocket above the​ ground is related to time by the following quadratic function:

h(t) = -16t² + Vit

Part 1.

When the initial velocity is 320 feet per seconds, the height function becomes;

h(t) = -16t² + 320t

Part 2.

Generally speaking, the height of this rocket would be equal to zero (0) when it hits the ground. Therefore, we would equate the height function to zero (0) as follows:

0 = -16t² + 320t

320t = 16t²

Time, t = 320/16

Time, t = 20 seconds.

Part 3.

Next, we would determine the maximum height of this rocket by taking the first derivate in order to determine the time (t) it takes;

h(t) = -16t² + 320t

h'(t) = -32t + 320

320 = 32t

t = 320/32 = 10 seconds.

Part 4.

The maximum height of this rocket is given by;

h(10) = -16(10)² + 320(10)

h(10) = 1,600 feet.

Part 5.

At a height of 800 feet, the time is given by;

800 = -16t² + 320t

16t² - 320t + 800 = 0

t² - 20t + 50 = 0

Time, t = 2.9 or 17.1 seconds.

Alice and Bob each have a certain amount of money. If Alice receives n dollars from Bob, then she will have 7 times as much money as Bob. If, on the other hand, she gives n dollars to Bob, then she will have 2 times as much money as Bob. If neither gives the other any money, what is the ratio of the amount of money Alice has to the amount Bob has?

Answers

The ratio of the amount of money Alice has to the amount Bob has is approximately 3.36 : 1.

How to find the ratio of money ?

According to the problem, two equations can be set up:

If Alice receives n dollars from Bob, then she will have 7 times as much money as Bob. This gives us the equation:

A + n = 7(B - n)

If Alice gives n dollars to Bob, then she will have 2 times as much money as Bob. This gives us the second equation:

A - n = 2(B + n)

We can rearrange these equations to make them easier to solve:

8n = 7B - A

3n = A - 2B

Setting these equal to each other, since they are both equal to 24n, gives:

21B - 3A = 8A - 16B

37B = 11A

A / B = 37 / 11

= 3. 36

what is between fractions 6/6 and 6/7

Answers

The fraction 13/7 lies between the fractions 6/6 and 6/7.

We have,

Between the fractions 6/6 and 6/7, there are infinitely many fractions.

To find a fraction that lies between these two fractions, we can take their average.

The fraction 6/6 simplifies to 1, and the fraction 6/7 cannot be simplified further.

To find the average, we add the two fractions and divide the sum by 2:

(6/6 + 6/7) / 2

To add the fractions, we need a common denominator, which is the least common multiple (LCM) of 6 and 7, which is 42.

Converting the fractions to have a common denominator:

(6/6) x (7/7) + (6/7) x (6/6) / 2

Simplifying the expression:

(42/42 + 36/42) / 2

Combining the numerators:

(78/42) / 2

Dividing:

78/42 = 13/7

Thus,

The fraction 13/7 lies between the fractions 6/6 and 6/7.

Answers

Answer:

[tex]\cos G=\dfrac{2}{3}[/tex]

[tex]\csc E=\dfrac{3}{2}[/tex]

[tex]\cot G=\dfrac{2}{\sqrt{5}}[/tex]

Step-by-step explanation:

If the right angle of right triangle EFG is ∠F, then EG is the hypotenuse, and EF and FG are the legs of the triangle. (Refer to attached diagram).

Given ΔEFG is a right triangle, and EG = 6 and FG = 4, we can use Pythagoras Theorem to calculate the length of EF.

[tex]\begin{aligned}EF^2+FG^2&=EG^2\\EF^2+4^2&=6^2\\EF^2+16&=36\\EF^2&=20\\\sqrt{EF^2}&=\sqrt{20}\\EF&=2\sqrt{5}\end{aligned}[/tex]

Therefore:

EF = 2√5FG = 4EG = 6

[tex]\hrulefill[/tex]

To find cos G, use the cosine trigonometric ratio:

[tex]\boxed{\begin{minipage}{9 cm}\underline{Cosine trigonometric ratio} \\\\$\sf \cos(\theta)=\dfrac{A}{H}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

For angle G, the adjacent side is FG and the hypotenuse is EG.

Therefore:

[tex]\cos G=\dfrac{FG}{EG}=\dfrac{4}{6}=\dfrac{2}{3}[/tex]

[tex]\hrulefill[/tex]

To find csc E, use the cosecant trigonometric ratio:

[tex]\boxed{\begin{minipage}{9 cm}\underline{Cosecant trigonometric ratio} \\\\$\sf \csc(\theta)=\dfrac{H}{O}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

For angle E, the hypotenuse is EG and the opposite side is FG.

Therefore:

[tex]\csc E=\dfrac{EG}{FG}=\dfrac{6}{4}=\dfrac{3}{2}[/tex]

[tex]\hrulefill[/tex]

To find cot G, use the cotangent trigonometric ratio:

[tex]\boxed{\begin{minipage}{9 cm}\underline{Cotangent trigonometric ratio} \\\\$\sf \cot(\theta)=\dfrac{A}{O}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

For angle G, the adjacent side is FG and the opposite side is EF.

Therefore:

[tex]\cot G=\dfrac{FG}{EF}=\dfrac{4}{2\sqrt{5}}=\dfrac{2}{\sqrt{5}}[/tex]

How to use Pascal’s triangle to find x^2 using the difference quotient formula

Answers

Using Pascal's triangle and the difference quotient formula, we expand (x + h)^2 and simplify the expression to (2hx + h^2) / h. As h approaches 0, the term h becomes negligible, and we are left with 2x, which represents the derivative of x^2.

To use Pascal's triangle to find x^2 using the difference quotient formula, we can follow these steps:

1. Write the second row of Pascal's triangle: 1, 1.

2. Use the coefficients in the row as the binomial coefficients for (x + h)^2. In this case, we have (1x + 1h)^2.

3. Expand (x + h)^2 using the binomial theorem: x^2 + 2hx + h^2.

4. Apply the difference quotient formula: f(x + h) - f(x) / h.

5. Substitute the expanded expression into the formula: [(x + h)^2 - x^2] / h.

6. Simplify the numerator: (x^2 + 2hx + h^2 - x^2) / h.

7. Cancel out the x^2 terms in the numerator: (2hx + h^2) / h.

8. Divide both terms in the numerator by h: 2x + h.

9. As h approaches 0, the term h becomes negligible, and we are left with the derivative of x^2, which is 2x.

N=15, p=.45, q=.55 find the probability of fewer than 3

Answers

Answer:

The binomial distribution formula is given by:

P(X = k) = (nCk) * p^k * q^(n-k)

where:

P(X = k) is the probability of getting exactly k successes

n is the number of trials

k is the number of successes

p is the probability of success in a single trial

q is the probability of failure in a single trial (1 - p)

(nCk) is the binomial coefficient, calculated as n! / (k!(n-k)!)

In this case, we have n = 15, p = 0.45, and q = 0.55.

Now, let's calculate the probability of getting fewer than 3 successes (0, 1, or 2).

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

P(X = 0) = (15C0) * (0.45^0) * (0.55^15)

P(X = 1) = (15C1) * (0.45^1) * (0.55^14)

P(X = 2) = (15C2) * (0.45^2) * (0.55^13)

Using the binomial coefficient formula (nCk) = n! / (k!(n-k)!), we can calculate:

P(X = 0) = (1) * (1) * (0.55^15)

P(X = 1) = (15) * (0.45) * (0.55^14)

P(X = 2) = (15C2) * (0.45^2) * (0.55^13)

By substituting the given values and evaluating these equations, we can find the probability of fewer than 3 successes.

Any imaginary number can be written as a real number

If you take any real number and
multiply it by i-squared it will stay a real number

If you take any number and multiply it by i-squared nothing will change

Any real number can be written as an imaginary number

Answers

Statements 1, 3, and 4 are true, while statements 2 and 5 are false.

Among the given statements, the following are true:

1. If you take any number and multiply it by i-squared, the sign(s) will change.

This statement is true. The complex number i is defined as the square root of -1. When we multiply any real or complex number by i-squared, it is equivalent to multiplying it by -1. Multiplying by -1 changes the sign of the number.

3. If you take any real number and multiply it by i-squared, it will stay a real number.

This statement is also true. Multiplying any real number by i-squared is equivalent to multiplying it by -1. Since -1 is a real number, the result will also be a real number.

4. If you take any number and multiply it by i-squared, nothing will change.

This statement is false. Multiplying any number by i-squared results in a change because i-squared is equal to -1. The multiplication by -1 changes the sign of the number.

As for the remaining statements:

2. Any imaginary number can be written as a real number.

This statement is false. Imaginary numbers, which involve the imaginary unit i, cannot be written as real numbers because they do not have a real component. They can only be expressed in the form of a real number multiplied by i.

5. Any real number can be written as an imaginary number.

This statement is false. Real numbers do not have an imaginary component, so they cannot be written as imaginary numbers. Imaginary numbers have a unique form with the imaginary unit i in the expression.

To summarize, statements 1, 3, and 4 are true, while statements 2 and 5 are false.

Kevin and David can paint a house in 6 days and 9 days respectively. They work together for 3 days
and then David quits the job. If Kevin completes the remaining work alone, what is the total
number of days taken to paint the house?

Answers

Kevin takes to complete the remaining work alone:

3 + 1 = 4 days in total.

Let's calculate the rates at which Kevin and David can paint the house individually.

Kevin's rate of work is 1/6 of the house per day (since he can complete the house in 6 days), and David's rate is 1/9 of the house per day (since he can complete the house in 9 days).

When they work together for 3 days, their combined rate is:

(1/6 + 1/9) of the house per day = 5/18 of the house per day.

In 3 days, they complete:

3 * (5/18) = 5/6 of the house.

The remaining work is 1 - (5/6) = 1/6 of the house.

Now, since Kevin is completing the remaining work alone, his rate is 1/6 of the house per day.

To determine how many days it takes for Kevin to complete the remaining work, we divide the remaining work (1/6) by Kevin's rate (1/6):

(1/6) / (1/6) = 1 day.

Therefore, it will take Kevin 1 additional day to complete the remaining work alone.

The total number of days taken to paint the house is the initial 3 days they worked together plus the additional day Kevin takes to complete the remaining work alone:

3 + 1 = 4 days in total.

Find the value of x in the parallelogram

Answers

The value of x in the parallelogram is 112°.

In a parallelogram, adjacent angles are always supplementary. This means that the sum of two adjacent angles in a parallelogram is always 180 degrees.

To understand this concept, let's consider a parallelogram ABCD. The opposite sides of a parallelogram are parallel and equal in length, and the opposite angles are congruent. Adjacent angles are those that share a side. Let's say angle A and angle B are adjacent angles in the parallelogram.

Since opposite angles of a parallelogram are congruent, we have angle A is congruent to angle C, and angle B is congruent to angle D.

Now, let's consider angle A and angle B. The sum of angle A and angle B is equal to the sum of angle C and angle D because opposite angles are congruent.

Therefore, we can conclude that angle A + angle B = angle C + angle D = 180 degrees.

This property holds true for all parallelograms. So, in any parallelogram, the adjacent angles are always supplementary, meaning their sum is 180 degrees.

For the given question, we know x° + 68° = 180°.

Then x° = 180° - 68°

x° = 112°

The following are six measures of solvency or profitability that can be determined from the given data of Gates Inc.:Debt ratio: The debt ratio measures the proportion of total assets that are financed by the creditors. It is calculated as: Debt ratio = Total liabilities / Total assets= 3,000,000 / 7,000,000= 0.43 or 43%

Debt-to-equity ratio: The debt-to-equity ratio measures the amount of debt financing in relation to the amount of equity financing. It is calculated as: Debt-to-equity ratio = Total liabilities / Total stockholders' equity= 3,000,000 / 5,000,000= 0.6 or 60%Interest coverage ratio:

The interest coverage ratio measures the number of times the company can cover its interest expenses with its earnings before interest and taxes (EBIT). It is calculated as:Interest coverage ratio = EBIT / Interest expense= (18,900,000 - 120,000 - (1,570,000 + 930,000 - 100,000 - 400,000)) / 120,000= 174,760 / 120,000= 1.5 or 1.5 timesCash coverage ratio:

The cash coverage ratio measures the number of times the company can cover its interest expenses with its cash flow from operations. It is calculated as:Cash coverage ratio = (EBIT + Depreciation) / Interest expense= (18,900,000 - 120,000 - (1,570,000 + 930,000 - 100,000 - 400,000) + 3,200,000 / 10) / 120,000= 764,760 / 120,000= 6.4 or 6.4 times Return on assets (ROA):

The return on assets ratio measures the company's ability to generate earnings from its assets. It is calculated as:ROA = Net income / Total assets= 930,000 / [(7,000,000 + 3,000,000) / 2]= 930,000 / 5,000,000= 0.186 or 18.6%Return on equity (ROE): The return on equity ratio measures the company's ability to generate earnings from its equity financing. It is calculated as: ROE = Net income / Total stockholders' equity= 930,000 / 5,000,000= 0.186 or 18.6%

Identify the correct mean, median, and mode for the given data.
{2, 12, 8, 15, 8, 7, 3, 9}

Answers

Answer: all are 8

Mean:8
Median:8

Mode: 8

Step-by-step explanation:

Mean is the average: add all them up and divide by how many numbers there are

Median: is basically the middle number: put the line in number order and find the number in the middle

Mode: most frequent number

Answer:

Mean = 8

Median = 8

Mode = 8

Step-by-step explanation:

Finding the mean:

The mean is the sum of all the data points divided by the total number of data points.  Since there are 8 data points in total, we can find the sum and divide it by 8 to find the mean:

Mean = (2 + 12 + 8 + 15 + 8 + 7 + 3 + 9) / 8

Mean = (64) / 8

Mean = 8

Thus, the mean of the given data is 8.

Finding the median:  

The median is the value that lies in the middle of the data.  First, we must arrange the data in ascending numerical order:

2, 3, 7, 8, 8, 9, 12, 15.

Because there are 8 data points, we have two numbers in the middle, namely 8 and 8.  In order to find the mean, we find the average of these two numbers:

Median = (8 + 8) / 2

Median = 16 / 2

Median = 8

Thus, the median of the given data is 8.

Finding the mode:

The mode is the most frequently occurring value in a data set.  8 occurs most frequently so the mode of the given data is 8.
