Step-by-step explanation:

y= -200 - 72

y= -272

because -a - b = -x

this is a formula

To solve the quadratic equations you provided, we can use various methods depending on the equation's form and complexity.

Here's the best method for each equation:

1. x^2 - 3x = 10:

We can rearrange the equation and set it equal to zero:

x^2 - 3x - 10 = 0

This equation can be factored as:

(x - 5)(x + 2) = 0

Therefore, the solutions are x = 5 and x = -2.

2. 4x^2 + 29x - 60 = 0:

This equation doesn't factor easily, so we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

For this equation, a = 4, b = 29, and c = -60.

Plugging these values into the formula, we get:

x = (-29 ± √(29^2 - 4 * 4 * -60)) / (2 * 4)

Simplifying further, we find:

x = (-29 ± √(841 + 960)) / 8

x = (-29 ± √1801) / 8

These are the two solutions to the equation.

3. x^2 - 6x = 0:

Here, we can factor out the common term x:

x(x - 6) = 0

This equation will be true if either x = 0 or x - 6 = 0.

Therefore, the solutions are x = 0 and x = 6.

4. 5x^2 + 5 = 9x:

Rearranging the equation, we get:

5x^2 - 9x + 5 = 0

This equation doesn't factor easily, so we can again use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

Here, a = 5, b = -9, and c = 5.

Plugging these values into the formula, we have:

x = (-(-9) ± √((-9)^2 - 4 * 5 * 5)) / (2 * 5)

Simplifying further, we get:

x = (9 ± √(81 - 100)) / 10

x = (9 ± √(-19)) / 10

Since the discriminant is negative, the solutions to this equation are complex numbers.

Answer:

208

Step-by-step explanation:

There are 5 weekdays in a week and 2 weekend days. Since there are 4 weeks, multiply 5 times 4 to get 20 weekdays/month, and 2 times 4 to get 8 weekend days/month. 20 times 8 (the hours she sleeps) is 160 hours, and 8 times 6 is 48 hours. Put together, you get 208 total hours.

Part 1: Kate should buy 100 coats to maximize profits.Part 2: The probability that the coats sell out is 0.25 (25%), and the probability that they do not sell out is 0.75 (75%).

To maximize profits, Kate should consider the scenario where she sells all the coats without any left over at the end of the season.

Since the sales are uniformly distributed between 100 and 400, buying 100 coats ensures that she meets the minimum expected sales of 100. Purchasing more than 100 coats would increase costs without a guarantee of higher sales, potentially leading to excess inventory and lower profits.

Given that the sales are uniformly distributed between 100 and 400 coats, Kate's purchase of 100 coats covers the minimum expected sales.

The probability of selling out can be calculated by finding the proportion of the range covered by the desired sales (100 out of 300). Therefore, the probability of selling out is 100/300 = 0.25 or 25%. The probability of not selling out is the complement, which is 1 - 0.25 = 0.75 or 75%.

Step-by-step explanation:

The cone has a radius of 4 feet and a height of 6 feet when its volume is 32. A volume expression is used to describe an object's capacity.

Space is occupied in some way by every three-dimensional object. This region's size is measured in terms of volume. An object's volume is the area that it takes up inside of its three-dimensional boundaries. It might also be called the object's capacity. Volume serves as a unit of measurement for an object's capacity. For example, if a cup can carry 100 ml of water in its brim, it is said to have a 100 ml capacity. Volume is another name for how much room a three-dimensional object occupies.

given

A weight of 712.04 grams is provided.

Where B is the area of the base and h is the cone's height, we can calculate the volume of the cone as V = 1/3 B * h.

32 π = 1/3 B x 6 ft.

96 π = B x 6 ft.

16 π = B

Its radius is,

B =   π r², where r is the cone's radius, is the area formula for a circle.

16 π = π r²

16 = r²

r = 4 ft

The total monetary amount of song downloads is $1080190

The percentage of amount paid for  video online sales = 15%

Number of times the songs downloaded in last year = 991000 times

Number of times the video downloaded in last year = 550000 times

The cost for each download of song = $1.09

The cost for each download of video = $9

The total monetary amount of song downloads = Number of times the songs downloaded in last year × The cost for each download of song

Substitute the values in the equation

P(A and B) = P(A) × P(B) is the formula used to assess if two events are independent (B).

P(A) is the chance that event A will occur.

The chance that event B will occur is marked as P(B).

If the chance of both occurrences happening at the same time, P (A and B), equals the product of the individual probabilities of each event, P(A) x P(B), the events are called independent.

If, on the other hand, the chance of both occurrences occurring simultaneously is less than the product of the individual probabilities of each event, the events are deemed dependent.

Answer:

Step-by-step explanation:

The transitive property of equality says--in very informal terms--if thing 1 = thing 2 and thing 2 = thing 3, then thing 1 = thing 3.  See how thing 2 appears twice?  That's a "spoiler alert" for this question.

So, what are thing 1, thing 2, and thing 3?

Take a look at how the answer space begins:  9y.  That must be thing 1 because the conclusion of the transitive property is thing 1 = ...

Now, what is mentioned twice?  2x.  That must be thing 2.

The remaining expression is thing 3: 10x - 8y + 3.

So it goes like this:

9y = 2x

2x = 10x - 8y + 3

Therefore, 9y = 10x - 8y + 3

The average rate of return for a project that is estimated to yield a total income of $382,000 over four years, cost $695,000, and has a $69,000 residual value is 4.5% .

Here's how to solve for the average rate of return:

Total income = $382,000

Residual value = $69,000

Total cost = $695,000

Total profit = Total income + Residual value - Total cost

Total profit = $382,000 + $69,000 - $695,000

Total profit = -$244,000

The total profit is negative, meaning the project is not generating a profit. We will use the negative number to find the average rate of return.

Average rate of return = Total profit / Total investment x 100

Average rate of return = -$244,000 / $695,000 x 100

Average rate of return = -0.3518 x 100

Average rate of return = -35.18%

Rounded to one decimal place, the average rate of return is 35.2%. However, since the average rate of return is negative, it does not make sense in this context. So, we will use the absolute value of the rate of return to make it positive.

Average rate of return = Absolute value of (-35.18%)

Polly’s Pasta and Pizza Supply sells wholesale goods to local restaurants. They keep track of revenue earned from selling kitchen supplies and food products. The function K models revenue from kitchen supplies and the function F models revenue from food product sales for one year in dollars, where t represents the number of the month (1 – 12) on the last day of the month.

K(t)=15t^3–312t^2+1600t+1100

F(t)=36t3–720t2+3800t–1600

In which month was her revenue from food products the greatest? The least?

Answer:

greatest revenue = 4384

Leat revenue = 400 ; October

Step-by-step explanation:

Using the model :

Claculating the revenue from. Food sales from January through December :

F(t)=36t^3–720t^2+3800t–1600

Put t = 1, 2, 3,.. 12 for January through December

t = 1

F(1)=36(1^3) - 720(1^2) + 3800(1) - 1600 = 1516

t = 2

F(2) = 36(2^3) - 720(2^2) + 3800(2) - 1600 = 3408

Inputting the t values up to 12 to cover for January thkorugh December :

We have the data:

t1 = 1516

t2 = 3408

t3 = 4292

t4 = 4384

t5 = 3900

t6 = 3056

t7 = 2068

t8 = 1152

t9 = 514

t10 = 400

t11 = 996

t12 = 2528

Hence, greatest revenue = 4384 (month of April)

Least revenue is at t10(October) ; Lowest revenue is at t 10 = 400

The minimum distance the annihilation event could have occurred from the center of the machine is approximately 98.94 nanometers.

To determine the minimum distance the annihilation event could have occurred from the center of the machine, we can use the speed of light as a constant and the time difference between the collisions of the gamma rays.

The speed of light in a vacuum is approximately 299,792,458 meters per second (m/s).

Since the time difference between the collisions of the gamma rays is given as 0.33 nanoseconds, we need to convert this time to seconds. One nanosecond is equal to 1 × 10⁻⁹seconds.

0.33 nanoseconds is equal to 0.33 × 10⁻⁹ seconds.

Now, we can calculate the minimum distance using the equation:

Distance = Speed of light × Time

Distance = 299,792,458 m/s × 0.33 × 10⁻⁹ seconds

Distance ≈ 98.94 nanometers
