Answer:

AY = 10 cm.

Step-by-step explanation:

Given that, ΔABC is similar to ΔAXY

and [tex]\frac{AB}{AX }  = \frac{5}{3}[/tex]

⇒  [tex]\frac{AC}{AY }  =  [tex]\frac{BC}{XY } = \frac{5}{3}[/tex]

⇒ BC = XY× \frac{5}{3}[/tex] =  \frac{20}{3}[/tex] (as XY = 4 cm given)

Now, check the attached figure,

given, BY bisects ∠XYC

let ∠XYB = ∠BYC = x

⇒ ∠AYX = 180-2x (angle on a straight line)

and also ∠AYX = ACB (similar triangle properties)

⇒ ∠ACB = 180-2x

Now, sum of angles in ΔBYC = 180°

⇒ ∠YBC = x

⇒ BC = YC (as two sides of equal angles are equal in a triangle)

⇒ YC =  \frac{20}{3}[/tex]

And also [tex]\frac{AC}{AY }  = \frac{5}{3}[/tex]

AC = AY + YC

⇒ [tex]\frac{AY+YC}{AY }  = \frac{5}{3}[/tex]

⇒ [tex]\frac{AY+\frac{20}{3}[/tex]}{AY }  = \frac{5}{3}[/tex]

⇒ 5AY = 3AY + 20

⇒ AY = 10 cm

The equilibrium price 'p' is found when setting the supply and demand equations equal to each other and solving for p. Doing so gives us p = 29, which is not available among the provided options, suggesting an error in the question or answer options.

In the given situation, the point of equilibrium occurs when the quantity demanded (D) is equal to the quantity supplied (S). Therefore, we can set the demand equation equal to the supply equation and solve for p.

The equations at the moment are: D = p + 22 and S = 3p - 36.

Setting them equal to each other means setting D and S to the same value, resulting in: p + 22 = 3p – 36.

To solve for p, you first combine like terms, which will give you: 22 + 36 = 3p - p, simplifying that leads to: 58 = 2p.

Finally, to isolate p, divide both sides of the equation by 2: p = 58 / 2 = 29.

However, none of the options includes p = 29, which suggests there might be a typo or error in the provided choices or the equations.

Answer:

B. 28 degrees

Step-by-step explanation:

ok so,

the starting temperature is 35 degrees then the temperature dropped 4 degrees. making the temp 31 degrees. next the temperature rose 2 degrees, making it 33 degrees. lastly, the temperature dropped another 5 degrees making it 28 degrees out on wednesday.  

so the number line showing this would be B.

Final answer:

After a cold front caused the temperature to drop by 40 degrees from the initial 35 degrees Fahrenheit, the resulting temperature would be -5 degrees Fahrenheit on the number line for Wednesday morning at 8:00am.

Explanation:

The student originally observed a temperature of 35 degrees Fahrenheit on Sunday morning. If we suppose a cold front blows in and drops the temperature by 40.0 Fahrenheit degrees, the temperature change can be calculated by subtracting 40 from the initial temperature:

35 °F - 40 °F = -5 °F

Therefore, the number line that shows the temperature on Wednesday morning at 8:00am should have a point at -5 degrees Fahrenheit, representing the new temperature after the cold front.

The final concentration of salicylic acid in the ointment is approximately 8.70%.

To calculate the final concentration of salicylic acid in the ointment base, we need to know the total mass of the product after mixing. The final concentration of salicylic acid is expressed as a percentage, which is the mass of salicylic acid divided by the total mass of the product, multiplied by 100.

Let's assume that when you add 8 g of salicylic acid to 84 g of the ointment base, there is no change in the total volume, and the two substances mix completely.

Total mass of the product = Mass of salicylic acid + Mass of ointment base

Total mass = 8 g + 84 g = 92 g

Now, we can calculate the final concentration of salicylic acid:

Final Concentration (%) = (Mass of salicylic acid / Total mass) * 100

Final Concentration (%) = (8 g / 92 g) * 100 ≈ 8.70%

So, the final concentration of salicylic acid in the ointment is approximately 8.70%.

Final answer:

The equation that represents Giovanna's current situation is Current Salary = $42,840.

Explanation:

The equation that represents Giovanna's current situation can be determined by using the formula for calculating annual salary with a percentage increase.

The formula is:
Current Salary = Initial Salary + (Percentage Increase * Initial Salary)

Using this formula, we can substitute the given values:
Initial Salary = $42,000
Percentage Increase = 2% (or 0.02)

Substituting these values into the formula:

Current Salary = $42,000 + (0.02 * $42,000)

Simplifying the equation:

Current Salary = $42,000 + $840

Current Salary = $42,840

Therefore, the equation that represents Giovanna's current situation is:
Current Salary = $42,840

Final answer:

The Peace of Augsburg allowed rulers to establish either Lutheranism or Roman Catholicism as the official religion in their lands, giving birth to the principle 'whose realm, their religion' but excluded other religious groups such as Calvinists and Anabaptists.

Explanation:

The religious settlement reached with the Peace of Augsburg in 1555 allowed rulers within the Holy Roman Empire to choose either Lutheranism or Roman Catholicism as the official religion of their territories. This principle, known as cuius regio, eius religio ('whose realm, their religion'), meant that a ruler's subjects were obliged to follow the same religion.

The Peace of Augsburg formally recognized the division between Catholics and Protestants, mainly Lutherans, and ended the religious conflict within the empire at that time. However, other religious groups, such as Calvinists and Anabaptists, were not accommodated, and the agreement failed to resolve underlying tensions leading to future wars, including the devastating Thirty Years' War.

Step-by-step explanation:

Given: [tex]$ \frac{- 12x^4}{x^4 + 8x^5} $[/tex]

Taking [tex]$ x^4 $[/tex] common outside in the denominator, we get:

[tex]$ = \frac{-12x^4}{(x^4)(1 + 8x)} $[/tex]

[tex]$ x^4 $[/tex] will get cancelled on the numerator and denominator, we get:

[tex]$ = \frac{-12}{1 + 8x} $[/tex]

we know that the denominator can not be zero.

That means, 1 + 8x [tex]$ \ne $[/tex] 0.

[tex]$ \implies 8x \ne -1 $[/tex]

[tex]$ \implies x \ne \frac{-1}{8} $[/tex]

So, the answer is: [tex]$ \frac{-12}{1 + 8x} $[/tex], where [tex]$ x \ne \frac{-1}{8} $[/tex].

Answer:

par value of the TIPS is $1034.05

Step-by-step explanation:

Given:

-  original reference CPI = 182.1

- current CPI = 188.3

Assume face value of tips = $1000

par value of the TIPS = [tex]face\ value\ of\ tips\times \frac{current\ CPI}{original\ reference\ CPI}[/tex]

par value of the TIPS = [tex]1000\times \frac{188.3}{182.1}\approx $1034.05[/tex]

Final answer:

The par value of a TIPS adjusts with the CPI's inflation rate. To find the adjusted par value of a 4.15% TIPS, multiply the original par value by 1 plus the inflation rate, which is determined by the percentage increase from the original to the current CPI.

Explanation:

A student asked about the par value of a Treasury Inflation-Protected Security (TIPS) given an original reference Consumer Price Index (CPI) of 182.1 and a current CPI of 188.3. The par value of TIPS adjusts with inflation to protect investors, with the adjustment based on the change in the CPI.

First, we need to calculate the percentage increase in the CPI by using the formula:

(Current CPI - Original CPI) ÷ Original CPI x 100%.

Plugging in the given CPI values:

(188.3 - 182.1) ÷ 182.1 = 0.0340 or 3.40%

This percentage tells us how much the CPI has increased since the TIPS was issued. To find the adjusted par value, you would multiply the original par value of the TIPS (which is typically $1,000) by 1 plus the inflation rate. Since we do not have the original par value, we can only provide the formula for its calculation.

The adjusted par value would be:

Original Par Value x (1 + Inflation Rate).
