whats the slope for (-3, -4) and (-2, -10)

True.

If adding two positive integers results in a negative number, it means that an overflow has occurred. The overflow flag is set when the result of an operation is too large to be represented with the given number of bits.
If bx and dx both contain positive integers and adding them produces a negative result, the overflow flag will be set. This is because when two positive integers are added, the result should also be a positive integer. If the result is negative, it means there was an overflow during the addition process, and the overflow flag will be set to indicate this issue.

Without knowing the total cost of the wallpaper or the dimensions of the rectangular prism, it is not possible to determine the cost of the wallpaper per square foot.

To calculate the cost per square foot, we would need to know the total cost of the wallpaper and the total area covered by the wallpaper. Since we do not have this information, we cannot determine the cost per square foot.

In summary, the cost of the wallpaper per square foot cannot be determined without knowing the total cost of the wallpaper and the dimensions of the rectangular prism that Lamar built.

Answer:

53 caramelos

Step-by-step explanation:

El número total de caramelos en el frasco = 180 caramelos

Para Laura

Laura se ha comido la décima parte de un frasco

1/10 × 180 caramelos = 18 caramelos

Por Marta

Marta una novena

1/9 × 180 = 20 caramelos

Por Cristina

Cristina una quinta.

1/5 × 180 = 36 caramelos.

De lo que queda, Juan se ha comido la mitad.

La cantidad de caramelos que quedan se calcula como:

180 - (18 + 20 + 36)

= 180 - 74

La cantidad de caramelos que quedan = 106 caramelos

Para juan

De lo que queda, Juan se ha comido la mitad.

= 1/2 × 106

= 53 caramelos

¿Cuántos dulces quedan?

= 106 caramelos - 53 caramelos

= 53 caramelos

Por tanto, quedan 53 caramelos.

the value of |x-2| lies between 0 and 1 then λ also lies between 0 and 1. Then λ belongs to (0,1).

In the given question, if λ∈R and the domain of f(x) = \(\sqrt{\frac{log_{\lambda}|x-2|}{|x|}}\) is [1,2)∪(2,3], then λ belong to

The given function is

f(x) = \(\sqrt{\frac{log_{\lambda}|x-2|}{|x|}}\)

The function is belong in between [1,2)∪(2,3]. So

|x-2| ≠ 0  and  |x| > 0

x ≠ 2       and  x > 0

Since the value of x can not be equal to 2 and x value is always greater than 0. So

\(log_{\lambda}|x-2|\geqslant 0\)

The value of |x-2| should be lies between 0 and 1 because x cannot be equal to 2 and greater than 1.

So 0< |x-2| < 1

If the value of |x-2| lies between 0 and 1 then λ also lies between 0 and 1.

Hence, 0 < λ < 1.

a. There is a negative externality present in the description and cost function.

b. Firm 1 produces 10 units of output (x), while Firm 2 produces 70 units of output (y). The profit for Firm 1 is $190, and the profit for Firm 2 is $1,800.

c. If both firms are merged, the joint output is 80 units (x + y), and the joint profit is $1,990.

d. Yes, the government can apply a tax/subsidy to improve efficiency.

a. The negative externality arises from the cost function of Firm 2, which includes a term (-10x) dependent on Firm 1's output. This indicates a cost imposed on Firm 2 due to Firm 1's production level.

b. To maximize their profits independently, Firm 1 sets its output level (x) where marginal cost equals the competitive price, resulting in x = 10. Firm 2 sets its output level (y) where marginal cost equals the competitive price, considering Firm 1's output level, leading to y = 70. The profit for each firm is calculated using the given cost functions and competitive prices.

c. When the firms are merged into one business, their individual outputs (x and y) are combined, resulting in a joint output of 80 units. The joint profit is the sum of the individual profits obtained by calculating the revenue and costs for the merged business. In this case, the joint profit is $1,990, which is higher than the combined profit of the individual firms.

d. To address the negative externality, the government can impose a per-unit tax on Firm 1's output equal to the external cost imposed on Firm 2. The tax revenue can then be used to subsidize Firm 2's production. This mechanism helps internalize the externality and improve efficiency by aligning private costs with social costs.

Answer:

y = - 4x + 13

Step-by-step explanation:

In order to do this problem you would need a whole new equation, but you will use what is given to you:

instead of going with:

x - 4y = 20

Turn it into y = mx + b form, also known as slope-intercept form:

x - 4y = 20

-x       = -x

_________

- 4y = 20 - x

Then divide both sides by - 4:

\(\frac{-4y}{-4} = \frac{-x + 20}{-4}\)

You will then get:

y = \(\frac{1}{4}x - 5\)

From this equation we will only need the slope!

m || = \(\frac{1}{4}\)

(This slope is for parallel)

but if you want perpendicular to the slope, then we need the negative reciprocal!

Negative reciprocal is a flipped version of the value that is negative, for example:

2 = \(-\frac{1}{2}\)

Because \(\frac{2}{1}\) = 2

Now we will find the perpendicular slope which is:

m ⊥ = - 4

Now substitute this slope into slope intercept form:

y = mx + b

(-3) = -4(4) + b

(Take away parentheses)

-3 = -16 + b

(Move - 3 to the other side, by making it positive, but what you do to one side, you do to the other)

= -13 + 6

(Move - 13 to the other side, by make - 13 into +13)

+13 = +13

________

13 = b

(This is you b, also known as you intercept)

Your answer is:

y = -4x + 13

The word problem's solution states that 86 adult tickets were sold on that particular day.

A mathematical statement that demonstrates the equality of two expressions is called an equation. The two expressions are separated by the equal character "=". Variables, constants, and mathematical operations like multiplication, division, addition, subtraction, exponents, etc. may be used in the equations on either side of the equal sign.

Assume that "c" represents the number of child tickets sold and "a" represents the number of adult tickets sold.

From the information provided, we understand that:

A young person's ticket costs $6.10

A ticket for an adult costs $9.40.

There have been 136 tickets sold in total.

$1027.60 has been earned in total from the selling of tickets.

To express the provided information, we can put up two equations:

c + a = 136 (Equation 1: amount of tickets sold overall)

6.10c + 9.40a = 1027.60 (Equation 2: the total amount made from ticket sales)

Equation 1 can be used to express "c" in terms of "a" in order to solve for "a":

c = 136 - a

By entering this expression in place of "c" in Equation 2, we obtain:

6.10(136 - a) + 9.40a = 1027.60

By enlarging and streamlining this equation, we arrive at:

830.96 - 2.3a = 1027.60

830.96 from both sides is subtracted to arrive at:

-2.3a = 196.64

By multiplying both sides by -2.3, we obtain:

a ≈ 85.5

We can round this up to 86 as "a" denotes the quantity of adult tickets that were sold. As a result, 86 adult tickets were sold on that particular day.

The cosine function to model the height of a water particle above and below the mean water line is h = 2·cos((π/30)·t)

Step-by-step explanation:

The cosine function equation is given as follows h = d + a·cos(b(x - c))

Where:

\(\left | a \right |\) = Amplitude

2·π/b = The period

c = The phase shift

d = The vertical shift

h = Height of the function

x = The time duration of motion of the wave, t

The given data are;

The amplitude \(\left | a \right |\) = 2 feet

Time for the wave to pass the dock

The number of times the wave passes a point in each cycle = 2 times

Therefore;

The time for each complete cycle = 2 × 30 seconds  = 60 seconds

The time for each complete cycle = Period = 2·π/b = 60

b = π/30 =

Taking the phase shift as zero, (moving wave) and the vertical shift as zero (movement about the mean water line), we have

h = 0 + 2·cos(π/30(t - 0)) = 2·cos((π/30)·t)

The cosine function is h = 2·cos((π/30)·t).

The expression to model the amount of the file downloaded is:

D = (t(t + 1))/2 - 1

Here, we have,

To model the amount of the file downloaded over time, we can observe that the pattern of the downloaded kilobytes follows a specific pattern. Notice that the amount of the file downloaded is increasing by 1 kilobyte every minute, and the starting point is at 0 kilobytes.

Based on this pattern, we can represent the amount of the file downloaded as a quadratic function of time (minutes).

Let's denote the amount of the file downloaded as D and the time in minutes as t.

Since the amount of the file downloaded is increasing by 1 kilobyte every minute, we can express it as the sum of the consecutive positive integers.

The sum of the first n positive integers can be given by the formula (n(n + 1))/2.

In this case, we want to find an expression that represents the sum of the first n positive integers, where n represents the time in minutes. However, since the starting point is 0 kilobytes downloaded, we need to subtract 1 from the sum to account for this.

Therefore, the expression to model the amount of the file downloaded is:

D = (t(t + 1))/2 - 1

This expression represents the sum of the first t positive integers, subtracting 1 to account for the starting point at 0 kilobytes downloaded. It will give us the amount of the file downloaded at any given time t in minutes.

An exponential decay function is a mathematical function that describes the decrease in value of a quantity over time or through a series of events. It is often used to model natural phenomena such as radioactive decay or the spread of diseases.

In an exponential decay function, the value of the quantity decreases exponentially over time. This means that the rate of decrease is proportional to the value of the quantity at any given time.

The exponential decay function is characterized by a decreasing graph that approaches zero but never touches the x-axis. The rate of decay slows down over time, but the quantity never completely disappears. The function is used in various fields such as physics, chemistry, biology, finance, and economics, to name a few.

1. This situation represents exponential decay because the value of the computer decreases by 16.5% each year.

2. Josh's function represents the situation correctly because it involves the decay factor (0.835) which is less than 1, reflecting the decrease in value each year. Eve's function represents exponential growth which is not consistent with the situation where the value of the computer decreases each year.

3. V(x) = 1275(0.835)ˣ represents the function using the form V(x) = a(b)ˣ where a = 1275 and b = 0.835.

Alternatively, V(x) = 1275(1-0.165)ˣ represents the function using the form V(x) = a(1-r)ˣ where a = 1275 and r = 0.165.
