Final answer:

The conference rooms can accommodate approximately 34 attendees each, and the ballrooms can accommodate approximately 31 attendees each.

Explanation:

To find out how many attendees each room can accommodate, we need to divide the total number of attendees by the total number of rooms.

For the quarterly meeting, there are 2 conference rooms and 5 ballrooms, which can seat a total of 238 attendees. To find out how many attendees each room can accommodate, we divide 238 by 7 (2 + 5), which gives us approximately 34 attendees per room.

For the safety training event, there are 4 conference rooms and 5 ballrooms, which can seat a total of 286 attendees. Dividing 286 by 9 (4 + 5) gives us approximately 31 attendees per room.

x = - 3 with multiplicity 2

Step-by-step explanation:

f(x) = (x - 3)(x + 3)(x + 3) = (x - 3)(x + 3)²

Equating each factor to zero and solving for x

x - 3 = 0 ⇒ x = 3 with multiplicity 1

x + 3 = 0 ⇒ x = - 3

x + 3 = 0 ⇒ x = -3

Thus x = - 3 has multiplicity of 2

The fact that the factor is squared gives the multiplicity

Step-by-step explanation:

Quadratic model is shaped like a "U", or a parabola

Quartic model is shaped like a "W", highest degree is 4 (x^4).

Linear model is a line.

Cubic model is x^3, shaped like a curvy snake.

Looking at the graph, it clearly shows a line. So, linear model is the answer.

C is the correct answer.

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3y + 2x = 1 into this form

Subtract 2x from both sides

3y = - 2x + 1 ( divide all terms by 3 )

y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{1}{3}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{2}{3}[/tex] → A

By rearranging the equation 3y + 2x = 1 into slope-intercept form, y = mx + b, we find that the slope of the line is -2/3. The correct answer is A.) -2/3.

The slope of the line whose equation is 3y + 2x = 1 is found by solving for y to get the line into slope-intercept form, which is y = mx + b, where m represents the slope.

Now that the equation is in slope-intercept form, we can see that the slope m is -2/3. Therefore, the correct answer is A.) -2/3.

12%*14000*3

Which is 5040

Therefore, it will have to pay back $4050

J.T. will pay back a total of $18,480 altogether.

To calculate the total amount J.T. will pay back, we can use the formula for simple interest:

[tex]\[I = P \times r \times t\][/tex]

Where:

- (I) = Interest

- (P\) = Principal amount (the initial loan amount)

- (r) = Annual interest rate (in decimal form)

- (t) = Time (in years)

Given that J.T. borrows $14,000 at an annual interest rate of 12% for 3 years, we can plug these values into the formula:

[tex][I = 14000 \times 0.12 \times 3\][/tex]

[I = 5040]

So, the total interest J.T. will pay is $5,040.

To find the total amount J.T. will pay back, we add the interest to the principal:

[Total amount = Principal + Interest]

[Total amount = 14000 + 5040]

[Total amount = 18440]

Therefore, J.T. will pay back a total of $18,480 altogether.

In summary, by using the formula for simple interest, we determined the interest amount J.T. will pay over the 3-year period, and then added it to the principal amount to find the total repayment amount.

Answer:

Step-by-step explanation:

In a normal equation, y=mx+b, the constant of variation is the thing that "constantly" "varies" and in other words changes the same. This is the slope. In the equation, the slope is m.

-4y=8x

y=-2x

The constant of variation, aka slope, is -2

Answer:

Step-by-step explanation: first, find y by itself by adding 2x to the other side then diving by the 5y to get y=2/5x +2! Rise 2, run 5 from your start at positive 2 on the graph and you should get line a!!!

The graph of the equation -2x + 5y = 10 has a positive slope of 2/5 and a y-intercept of 2. None of the provided options accurately describe the graph of the equation, as they indicate incorrect y-intercept values and describe the slope incorrectly.

To find which line is a graph of the equation -2x + 5y = 10, we need to identify the slope and the y-intercept of the line. To do this, we should rearrange the equation into slope-intercept form, which is y = mx + b where m is the slope and b is the y-intercept.

Rearranging the equation, we get:

5y = 2x + 10

y = (2/5)x + 2

The slope is the coefficient of x, which is 2/5, and the y-intercept is the constant term, which is 2. The line has a positive slope, and based on the slope-intercept form, it rises on the graph as the x-value increases. Therefore, option d with a positive slope and a y-intercept of 50 must have a typo since our y-intercept is 2. The correct interpretation would be that the line gradually moves upward on the graph as the x-value increases, thanks to its positive slope.

Hence, none of the provided options describe the graph of the equation -2x + 5y = 10 accurately because the y-intercept should be 2, not 50, and the slope is positive. Keep in mind that a positive slope results in an upward, not a downward, trend as x increases.

Answer: [tex]x=2[/tex]

Step-by-step explanation:

The equation for inverse variation is:

[tex]x=\frac{k}{y}[/tex]

Where "k" is the constant of variation.

If you solve for for the constant "k", you get the form:

[tex]k=xy[/tex]

So, if [tex]xy=2[/tex] then [tex]k=2[/tex]

Knowing the value of "k", you can find the value of "x" when [tex]y=1[/tex], by substituting these values into the equation [tex]x=\frac{k}{y}[/tex].

Therefore, you get that the value of "x" when [tex]y=1[/tex] is:

Answer:

t = 0.722 seconds

Step-by-step explanation:

Given in the question that an equation

h = -16t² + 6t + 4

here h is the height

        t is the time

To solve this question we need to substitute height with zero because at ground level height is zero

0 = -16t² + 6t + 4

a = -16

b = 6

c = 4

Formula to use

t = -b±√(b²-4ac) / 2a

Plug values in the formula

t = -6 ± √36-4(-16)(4) / 2(-16)

t =  6±2√73 / 32

t =  6+2√73 / 32 or t =  6-2√73 / 32

t = 0.722 or t = -0.347

since time can't be in negative so we reject  t = -0.347

Answer: Then you should pay her 4$ one hour

Step-by-step explanation:

Employees who earn increased commissions as their sales increase are paid a progressive commission. This method incentivizes employees to work harder to sell more, as their commission rate increases with sales volume.

Employees whose rate of commission increases as their sales increase are paid a progressive commission. With this method of remuneration, the more sales an employee makes, the higher their rate of commission becomes. This strategy is popular with both economists and the general public because it effectively incentivizes employees to work harder and achieve higher sales, leading to an increase in the overall performance of the business.

For example, a salesperson may earn a 10% commission on sales up to $10,000. However, any sales beyond that might attract a 15% commission rate, encouraging the employee to sell more. Such progressive commission schemes are common in sales-driven industries like real estate and retail.

Final answer:

Miryam Williams' total pay is $3,237.50.

Explanation:

To calculate Miryam Williams' total pay, we first need to calculate her commission.

Her commission is 3.5% of her total sales, which is $92,500.

Commission = 3.5% × $92,500 = $3,237.50.

Next, we need to determine if Miryam's commission exceeds $5,000.

Since her commission is $3,237.50, it does not exceed $5,000. Therefore, she does not receive the $500 bonus.

Finally, to calculate her total pay, we sum her commission and the bonus (which is $0 in this case).

Total Pay = Commission + Bonus = $3,237.50 + $0 = $3,237.50.

Using Pythagorean theorem, for the 8-feet wide picture window to pass through the 3-feet wide door, the door must be at least approximately 7.4 feet tall.

The picture window here is a rectangular sheet of glass. The longer side (8 feet) must fit through the door. The door is only 3 feet wide, which means that the 8-foot side of the window must be angled to pass through the door in vertical orientation.

To calculate the height of the door needed, consider the Pythagorean theorem which states that in a right triangle, the square of the hypotenuse (longest side) equals the sum of the squares of two sides (a2 + b2 = c2). Here 'a' is the width of the door (3 feet) and 'c' is the diagonal length of the window (8 feet). Solving for 'b' which represents the door's required height, we get:

b2 = c2 - a2

b2 = 82 - 32

b = sqrt(64 - 9) = sqrt(55)

Therefore, b is approximately 7.4 feet.

So the door must be at least 7.4 feet tall to pass the 8-feet picture window through it when angled vertically.
