Answer:

To convert the weight of the pitaya seed from ounces to standard form, we need to express it in scientific notation.

Given: Weight of the pitaya seed = 1x10^(-3) ounces

In standard form, the weight can be written as a decimal number between 1 and 10 multiplied by a power of 10.

1x10^(-3) in standard form is 0.001.

Therefore, the weight of the pitaya seed in standard form is 0.001.

The weight of a pitaya, or dragon fruit, is given as 1x10^3 ounces in scientific notation, which converts to 1000 ounces in standard form.

Scientific notation is a concise way to express very large or small numbers, using powers of 10. In this case, the weight of a pitaya, represented as 1x10^3 ounces in scientific notation, can be easily converted into standard form. The exponent, 3 in this instance, indicates the number of places the decimal point should be moved. Therefore, an exponent of 3 means shifting the decimal point three places to the right. Consequently, the weight of the pitaya in standard form is 1000 ounces. This method provides a clear and efficient way to handle large numbers, making complex calculations and comparisons more manageable.

The expression of the total cost can be divided in 2 parts, the one that represents the amount she has to pay per hour of reparation and the one that represents the taxes she has to pay over that amount.

The first part is 70h, and it represents the amount she pays when it takes h hours to repair her computer.

The second part is 0.08(70h) that represents the taxes, that are 8% of the cost of reparation. It means that the answer is 0.08(70h).

As the law of supply and demand states, there is an effect on the price of a product depending on its availability.

If there is a low supply and a high demand, there is an increase in price and vice versa.

Last 2012, there was a virus which infected millions of chicken. It was known as Avian influenza or bird flu. It resulted to scarcity of eggs.

As the law of supply and demand states, there is an effect on the price of a product depending on its availability.

For example we can use water. If a product becomes scarce its price would increase due to supply in demand.

If drinkable water became scarce its price would be greatly increased to its need and being in extreme demand.

In short,  if there is a low supply and a high demand, there is an increase in price and vice versa.

x and x⁴-16x²+56 are the resulting composite functions respectively.

Given the following functions below

f(x) = 7/x

g(x) = x² - 8

We need to determine the composite functions (fof)(x) and (gog)(x)

(fof)(x) = f(f(x))

f(f(x)) = f(7/x)

Replace x with 7/x

f(7/x) = 7/(7/x)

f(7/x) = 7 * x/7

f(7/x) = x

Similarly:

(gog)(x) = g(g(x))

g(g(x)) = (x² - 8)² - 8

g(g(x)) = x⁴-16x²+64 - 8

g(g(x)) = = x⁴-16x²+56

watercolour and each animal's response to the water as well as their total responses.

Explanation

When the water was blue, the total water consumed by both animals came to 1410 ml. The dog consumed more water than the cat. The dog drank 1200 ml while the cat drank just 410 ml.

When the color of the water was changed to green, the animals drank a total of 1300 ml. The cat drank 200 ml while the dog drank 1100 ml.

We can thus,  establish that there is an association between the color of the water and the volume of water taken by each animal because on the whole, both animals seem to prefer blue water. They drank more water when its color was blue and less when it was red.

I have chosen option (2) to discuss the downsides of trade under realistic conditions and its implications in the real world.

Original Post:

Trade is often hailed as a catalyst for economic growth and higher living standards, and for good reason. However, while trade undoubtedly brings numerous benefits, it is important to acknowledge that there can be downsides to this condition as well.

This can exacerbate existing inequalities and lead to social and economic disparities within nations.

Another challenge posed by trade is the vulnerability of domestic industries to international competition. When countries open their markets to global trade, domestic industries that are less competitive may face significant challenges. The adjustment process for workers and industries can be disruptive and requires effective policies to ensure a smooth transition and mitigate adverse effects.

Moreover, trade can have environmental consequences. increased production and transportation will lead to increased carbon emissions. The pursuit of economic growth through trade must be accompanied by sustainability measures and efforts to minimize the negative environmental impacts.

In the real world, we observe instances where the benefits of trade are not evenly distributed, and certain industries and regions may suffer from the consequences of global competition. Policymakers must address these downsides and implement measures to mitigate their impact. Unequal distribution of benefits, vulnerability of domestic industries, and environmental concerns are among the challenges that need to be carefully managed. By implementing appropriate policies and measures, countries can harness the potential of trade while mitigating its negative impacts, creating a more inclusive and sustainable global economy.

Response Post 1:

Peer: I completely agree with your post.  One aspect that concerns me is the impact of trade on cultural diversity. With globalization and increased trade, there is a risk of homogenization, where local traditions, languages, and cultural practices can be threatened. Countries need to strike a balance between benefiting from trade and preserving their unique cultural identities.

explain your thoughts in detail.

Response Post 2:

Peer: Your post raises valid points about the downsides of trade. One aspect that I find concerning is the reliance on foreign markets for essential goods. While trade allows countries to access a wide range of products and services, it also creates dependencies. In situations such as trade disputes, geopolitical tensions, or disruptions in global supply chains, countries can face challenges in meeting their domestic needs. Developing a diversified and resilient domestic economy becomes crucial to mitigate these risks.

The percent change from 1994 to 1995 can be computed by which of the following methods.

The percent change from 1994 to 1995 would be computed by the following

Formula: Percent Change = ((New Value - Old Value) / Old Value) x 100Where,

Old Value = Annual caseloads in 1994 = 750

New Value = Annual caseloads in 1995 = 820

Let's put these values into the formula and calculate the percent change.

Percent Change = ((820 - 750) / 750) x 100

Percent Change = (70 / 750) x 100

Percent Change = 0.093 x 100

Percent Change = 9.3%

Therefore, the percent change from 1994 to 1995 would be 9.3%.

Answer:

Discriminant is -20 (D<0, no real roots)

Step-by-step explanation:

The Discriminant Formula:

\( \displaystyle \large{ D = {b}^{2} - 4ac}\)

First, arrange expression in the standard form or ax^2+bx+c = 0.

\( \displaystyle \large{ {x}^{2} - 4x = 9} \\ \displaystyle \large{ {x}^{2} - 4x - 9 = 0}\)

From above, we subtract both sides by 9.

Compare the coefficients:

\( \displaystyle \large{a {x}^{2} + bx + c = {x}^{2} - 4x - 9}\)

Substitute a = 1, b = -4 and c = -9 in the formula.

\( \displaystyle \large{ D = {( - 4)}^{2} - 4(1)( - 9)} \\ \displaystyle \large{ D = 16 - 4( - 9)} \\ \displaystyle \large{ D = 16 - 36} \\ \displaystyle \large{ D = - 20}\)

Therefore the discriminant of equation is -20 which is less than 0.

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x) , that is

f(3) = 3 - 5 = - 2

Answer:

If \(f(x)=x-5\), f(3) = -2

Step-by-step explanation:

We are given \(f(x)=x-5\) and we need to find f(3)

For finding f(3), we put x= 3 in the given function.

\(f(x)=x-5\)

Putting x=3

\(f(3)=3-5\\f(3)=-2\)

The percentage strength of neomycin in the final compounded product is approximately 2.5%.

To determine the percentage strength of neomycin in the final compounded product, we need to calculate the weight of neomycin in the cream and divide it by the total weight of the cream.

Neomycin (5%) cream: 30g

The neomycin content is 5% of the total cream weight. To find the weight of neomycin in the cream, we multiply the cream weight by the neomycin percentage:

Weight of neomycin = 30g × 0.05 = 1.5g

Now, to calculate the percentage strength of neomycin in the final compounded product, we divide the weight of neomycin by the total weight of the cream and multiply by 100:

Percentage strength of neomycin = (Weight of neomycin / Total weight of cream) × 100

Percentage strength of neomycin = (1.5g / 60g) × 100 ≈ 2.5

Therefore, the percentage strength of neomycin in the final compounded product is approximately 2.5%.

Step-by-step explanation:

y<-2x+6

y≤x+2

I graphed it.

Answer:

Given function:

f(t) = (-16t - 2)(t - 1)

The zeros of the function are the values of t when f(t) = 0

⇒ f(t) = 0

⇒ (-16t - 2)(t - 1) = 0

⇒ (t - 1) = 0  ⇒  t = 1

⇒ (-16t - 2) = 0  ⇒ t = -2/16 = -1/8

The zeroes tell us the time (in seconds) when the ball is at ground level (when its height is zero).

Since time is not negative, only one zero is meaningful:  t = 1

Therefore, the total journey of the ball, from throwing it to it hitting the ground, is 1 second.

The height the ball is thrown can be determined by inputting t = 0 into the function:

⇒ f(0) = (-16(0) - 2)(0 - 1)

⇒ f(0) = (0 - 2)(0 - 1)

⇒ f(0) = (-2)(-1)

⇒ f(0) = 2

Therefore, the height from which the beach ball is thrown is 2 ft.

Equation: y = (-16t-2)(t -1)

1) Finding zeros of the function?

To find zero's of the function y = 0

(-16t-2)(t -1) = 0

-16t - 2 = 0, t - 1 = 0

t = 2/-16, t = 1

t = -0.125, 1

2) What do the zero's tell us? Are they meaningful?

Answer: It tells us that the time is 1 seconds when the height of the ball is 0 or at rest.

3) From what height is the ball thrown?

Insert t = 0

y = (-16(0)-2)((0) -1)

y = 2
