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.

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.

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.

The door needs to be approximately 21.3 feet tall for the glass to pass through.

To determine the height of the door, we need to consider that the glass is 8 feet wide. Since the door is only 3 feet wide, the glass needs to fit through a smaller opening. We can use similar triangles to find the height of the door. Let's set up a proportion:

8 / 3 = H / 8

Cross-multiplying, we get:

3H = 64

H = 64/3

Therefore, the door needs to be approximately 21.3 feet tall for the glass to pass through.

Answer:

f(x) = (x + 4)² - 3

Step-by-step explanation:

The equation of a quadratic function in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = x² + 8x + 13

To obtain f(x) in vertex form use the method of completing the square

add/ subtract (half the coefficient of the x- term)² to x² + 8x

f(x) = x² + 2(4)x + 16 - 16 + 13

f(x) = (x + 4)² - 3 ← in vertex form

To find the roots of the quadratic equation -10x^2 + 12x - 9 = 0, we can use the quadratic formula:
x = \frac{-b ± \sqrt{b^2 - 4ac}}{2a}
where
a is the coefficient of x^2, which is -10,
b is the coefficient of x, which is 12,
c is the constant term, which is -9.
First, let's identify the coefficients in our equation:
a = -10
b = 12
c = -9
Next, we will calculate the discriminant (Δ) using the formula:
Δ = b^2 - 4ac
Plug in the values of a, b, and c:
Δ = (12)^2 - 4*(-10)*(-9)
Δ = 144 - 4 * 10 * 9
Δ = 144 - 360
Δ = -216
Since the discriminant is negative, the quadratic equation has two complex roots. We will still use the quadratic formula to find them:
x = \frac{-b ± \sqrt{Δ}}{2a}
Substitute b, Δ, and a into the formula:
x = \frac{-12 ± \sqrt{-216}}{2 * (-10)}
Now, let's split the square root of the negative discriminant into real and imaginary parts:
√(-216) = √(216) * √(-1) = 14.697 * i
where i is the imaginary unit such that i^2 = -1. Substituting this into our quadratic formula gives:
x = \frac{-12 ± 14.697i}{-20}
Now, divide both the real and imaginary parts by -20:
x₁ = \frac{-12}{-20} + \frac{14.697i}{-20}
x₂ = \frac{-12}{-20} - \frac{14.697i}{-20}
Simplify those equations:
x₁ = \frac{12}{20} - \frac{14.697i}{20}
x₂ = \frac{12}{20} + \frac{14.697i}{20}
Further simplify by reducing the fractions:
x₁ = 0.6 - 0.73485i
x₂ = 0.6 + 0.73485i
Therefore, the roots of the quadratic equation -10x^2 + 12x - 9 = 0 are approximately x₁ = 0.6 - 0.73485i and x₂ = 0.6 + 0.73485i.

Answer:

The solution is (3,13) and (-1,-3). So none of the mentioned options is correct.

Step-by-step explanation:

Given that

[tex]y = 4x + 1  (i)[/tex]

[tex]y = x^2 + 2x -2 (ii)[/tex]

Now, by susbstituting the value of 'y' from equation i to equation ii, we get

[tex]4x+1=x^2 + 2x -2[/tex]

[tex]0=x^2 + 2x -2-4x-1[/tex]

[tex]0=x^2 + (2x -4x) +(-2-1)[/tex]

[tex]0=x^2 + (-2x) +(-3)[/tex]

[tex]0=x^2 -2x -3[/tex]

[tex]x^2 -2x -3 = 0 (iii)[/tex]

Now by factorization, equation iii can be written as

[tex]x^2 -3x +x -3 = 0[/tex]

[tex]x(x -3) + 1(x -3) = 0[/tex]

[tex](x -3)(x +1) = 0[/tex]

x = 3 and x = -1

By putting the values of x in equation i, we get

y = 4(3) + 1

y = 12 +1

y = 13

and

y = 4(-1) + 1

y = -4 +1

y = -3

Therefore, the solution is (3,13) and (-1,-3). So none of the mentioned options is correct.

Final answer:

The car's average speed over the course of 5 days for a distance of 2359 miles was approximately 19.66 mph, which rounds to 20 mph.

Explanation:

To calculate the car's average speed in miles per hour, you divide the total distance traveled by the total time taken. In this case, the car traveled 2359 miles over the course of 5 days. Since there are 24 hours in a day, the total time in hours is 5 days multiplied by 24 hours per day.

Total time in hours = 5 days × 24 hours/day = 120 hours

Now we calculate the average speed using the formula:

Average speed = Total distance / Total time

Average speed = 2359 miles / 120 hours

When calculated, the average speed is approximately 19.66 miles per hour. Rounding to the nearest mile per hour gives us an average speed of 20 mph.

Answer:

a = 1, b = 7

Step-by-step explanation:

Given the 2 equations

3a + 6b = 45 → (1)

2a - 2b = - 12 → (2)

Multiply (2) by 3 and add to (1) to eliminate the term in b

6a - 6b = - 36 → (3)

Add (1) and (3) term by term

(3a + 6a) + (6b - 6b) = (45 - 36)

9a = 9 ( divide both sides by 9 )

a = 1

Substitute a = 1 in either (1) or (2) and solve for b

(1) → 3 + 6b = 45 ( subtract 3 from both sides )

6b = 42 ( divide both sides by 6 )

b = 7

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.

Step-by-step explanation:

Catherine only has $54, so she cannot spend more than that.

The canvas will cost at least $20, but we don't know how much exactly.

The tubes cost $8.50 each.

So, she starts with a total budget of $54, out of which she will buy paints (8.5x) and she wants to have at least $20 left for canvas.

So, we transpose those facts into the inequity:

54 - 8.5x > 20

Answer:

[tex]54- 8.5x>20[/tex]

Step-by-step explanation:

We must identify the quantities.

Painting canvas

Paint tubes (x):

$ 8.50 per tube = 8.50x

Available money:

$ 54

Then the expenses must not exceed $ 54, and the budget for the painting canvas must be greater than $ 20

The money after buying the paint tubes is:

[tex]54-8.50x[/tex]

We know that this amount must be greater than $ 20 because you need to buy the painting canvas. So  the inequality is:
