Vertex for y=2(x-3)^2 +1

Answer:

2400 N (Newtons)

Step-by-step explanation:

The weight of an object can be calculated using the equation:

Weight = mass * gravitational acceleration

Given:

Mass of the bed (m) = 120 kg

Gravitational acceleration (g) = 20 m/s²

Using the weight equation:

Weight = mass * gravitational acceleration

Weight = 120 kg * 20 m/s²

Weight = 2400 kg·m/s²

The unit of the weight is kilogram-meter per second squared (kg·m/s²), which is equivalent to the unit of force called Newton (N).

Therefore, the weight of the bed is 2400 Newtons (N).

Traveling the world is a popular dream for many people, including students. While there is no way to know for sure what the probability is that a sophomore student will travel the world, there are some factors that may influence their likelihood of doing so.

For example, students who have access to financial resources and support from their families may be more likely to travel than those who don't. Additionally, students who are studying subjects that are related to travel, such as international relations, may be more interested in exploring the world.

There are also other factors that can influence a student's travel plans, such as personal preferences, cultural background, and availability of opportunities. Ultimately, the decision to travel the world is a personal one that depends on a wide range of factors.

In summary, there is no definitive answer to the question of what the probability is that a sophomore student will travel the world. However, there are many factors that can influence their likelihood of doing so.

Answer:

A. 144

D. √9 * √16.  

Step-by-step explanation:

The product property of square roots states that for any two numbers (a and b), where both are greater than or equal to 0, the square root of a product is equal to the product of the square root:

[tex]\sqrt{ab}=\sqrt{a} *\sqrt{b}[/tex]

Thus, √(9 * 16) is equivalent to √9 * √16.  

We can see this mathematically if we evaluate the expressions:

[tex]\sqrt{(9*16)}=\sqrt{9}*\sqrt{16}\\ \sqrt{144}=3*4\\ 12=12[/tex]

Thus, the answers are A and D.

If you can only choose one answer, choose D because the question didn't explicitly ask us to evaluate √(9 * 16).

If you can choose multiple answers, choose A and D.

Incorrect,  the correct exponential growth equation as it accurately represents a starting value of 300 and a growth rate of 2%. Scott's equation

Neither Pierre nor Scott has the correct exponential growth equation.

The exponential growth equation represents a relationship where a quantity increases or grows exponentially over time. It is typically represented as y = a(1 + r)^x, where "a" represents the initial or starting value, "r" represents the growth rate (expressed as a decimal), "x" represents the time or number of periods, and "y" represents the resulting value after the growth.

In this case, Pierre's equation is y =[tex]300(1.02)^x.[/tex]This equation suggests a growth rate of 2% (0.02 as a decimal), which means that the quantity would increase by 2% with each period. This aligns with the given growth rate of 2%. Thus, Pierre's equation is correct.

On the other hand, Scott's equation is y = [tex]300(1.2)^x[/tex]. This equation suggests a growth rate of 20% (0.2 as a decimal), which means that the quantity would increase by 20% with each period. However, the given growth rate is 2%, not 20%. Therefore, Scott's equation is incorrect.

To summarize, Pierre's equation, y = 300(1.02)^x, is the correct exponential growth equation as it accurately represents a starting value of 300 and a growth rate of 2%. Scott's equation, y = 300(1.2)^x, does not match the given growth rate and is therefore incorrect.

The probability that the student chooses the correct order is 1/120 or approximately 0.0083, which is equivalent to 0.83%.

If the student randomly orders the events, there is only one correct order out of all possible permutations.

Hence, the likelihood of selecting the accurate sequence is equal to 1 over the total count of potential arrangements.

As there are 5 occurrences, the overall count of conceivable sequences is equivalent to 5 factorial (5!), amounting to 120.

Therefore, the probability that the student chooses the correct order is 1/120 or approximately 0.0083, which is equivalent to 0.83%.

Answer:

$3827.00

Step-by-step explanation:

To calculate the total compound amount at the end of six years with an interest rate of 1.5% compounded annually, we can use the formula for compound interest:

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

Where:

A = Total compound amount

P = Principal amount (initial investment)

r = Annual interest rate (as a decimal)

n = Number of times interest is compounded per year

t = Number of years

In this case:

P = $3500

r = 1.5% = 0.015 (as a decimal)

n = 1 (compounded annually)

t = 6 years

Substituting these values into the formula, we have:

A = 3500 * (1 + 0.015/1)^(1*6)

Calculating this expression, we get:

A ≈ 3500 * (1.015)^6 ≈ 3500 * 1.093717 ≈ 3827.00

Rounding the total compound amount to 2 decimal places, the final value is approximately $3827.00

c. The image is attached below.

d. No, it is not possible for a satellite to see 50% of the Earth's equator.

Satellite B will see more of the Earth's equator than Satellite A. This is because the viewing angle of Satellite B is larger than the viewing angle of Satellite A. The viewing angle of Satellite B is 60 degrees, while the viewing angle of Satellite A is 45 degrees.

The length of the equator in view of Satellite B is 24,000 miles. This can be calculated using the following formula:

length of the equator = 2 * [tex]\Pi[/tex] * radius * sin(m/2)

Use a third color to draw the viewing angle from Satellite C. Label the points of tangency J and K. If m/C=45", find the mJK and mJZK

Step 1: ?

Step 2: -9 + 2 + 3

Step 3: -7 + 3

To find the missing expression in Step 1, we need to work backwards from Step 3 to Step 1.

In Step 3, the expression "-7 + 3" gives us a result of -4.

In Step 2, the expression "-9 + 2 + 3" gives us a result of -4.

So, the missing expression in Step 1 should also evaluate to -4 when performed correctly.

Let's check the available options:

[-10 + -1 + 2] + (2 + 3) = -11 + 2 + 5 = -4

[-8 - 1] + (2 + 3) = -9 + 5 = -4

Step-by-step explanation:

The coefficients 9 & 6, divided by 3, equal 3 & 2.

For the exponents, if you divide the entire equation by xy, you need to subtract the corresponding exponents of x and y. Subtract the denominator's exponent from the numerator's exponent.

So, for the first part x^8/x^1=x^7

y^2/y^1=y

For the second part: x^3/x=x^2

y^4/y=y^3

The mean weekly expense, after correcting the incorrectly recorded week, is $81.25.

Given that Taylor recorded the past 16 weeks' expenses, excluding the incorrect recording of $90 as $38, we have 15 correct expense values.

Sum of correct expenses = $83.20 * 15 = $1248

Now we need to include the corrected expense of $90 instead of $38.

New sum of expenses = $1248 - $38 (incorrectly recorded) + $90 (corrected) = $1300

Finally, we calculate the mean by dividing the new sum by the total number of weeks, which is 16.

The given sequence is: (2x-7), (x-1), 3x, x, (x+2), 30, 10.

In an arithmetic progression, the common difference (d) between consecutive terms remains constant.

The common difference between the terms = (x - 1) - (2x - 7) = x - 1 - 2x + 7 = 6 - x

6 - x = 3x - (x - 1)

Let's denote the total number of books on the shelf as 'total_books', and the number of new books as 'new_books'.

The number of used books can be calculated as the difference between the total number of books and the number of new books:

used_books = total_books - new_books

To find the ratio of used books to all books on the shelf, we divide the number of used books by the total number of books:

Ratio of used books to all books = used_books / total_books

Substituting the expression for used_books, we have:

Ratio of used books to all books = (total_books - new_books) / total_books

Simplifying further:

Ratio of used books to all books = 1 - (new_books / total_books)

Therefore, the ratio of used books to all books on the shelf is equal to 1 minus the ratio of new books to total books.
