[tex]y=\pm\sqrt{3t-t^2}[/tex]

Step-by-step explanation:

The given polar equation is;

[tex]r=3\sin \theta[/tex]

We multiply  both sides by r

[tex]r^2=3r\sin \theta[/tex]

The corresponding rectangular equation is

[tex]y^2+x^2=3x[/tex]

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

[tex]y=\sqrt{3x-x^2}[/tex]

Let x=t,

Answer:

63.36 years

Step-by-step explanation:

This is a compound interest problem and the following information has been provided;

Principal, P = 1200

Interest rate, r = 4%

Accumulated amount, A = 14400

We are required to determine the number of years for the principal to accumulate to the given amount. We use the compound interest formula;

[tex]A=P(1+r)^{n}[/tex]

We substitute the given values into the formula and solve for n;

[tex]14400=1200(1+\frac{4}{100})^{n}\\12=(1.04)^{n}\\[/tex]

The next step is to introduce natural logarithms;

[tex]ln12=nln(1.04)\\n=\frac{ln12}{ln1.04}\\n=63.36[/tex]

Thomas has invested $1,200 at a 4% interest rate. Using the formula for compound interest and solving for time, it will take approximately 29.1 years for his account balance to reach $14,400.

Thomas has invested an amount of $1,200 into an account with a 4% interest rate. This type of problem involves the use of the formula for compound interest. The general formula for compound interest is: A = P(1 + r/n)^(nt), where:

In this case, we assume the interest is compounded annually, so n = 1. We rearrange the formula to solve for t, giving us the formula t = log(A/P) / log(1 + r).

Substituting the given values into the formula, we get t = log(14400/1200) / log(1 + 0.04), which gives a result of approximately 29.1 years. So, it will take around 29.1 years for the account balance to reach $14,400.

again the another form of circle is,

now equating the values of f in both equations,

-k=-3

i.e. k=3

therefore k=3

[tex]P(x)[/tex] has degree 3, so it takes the general form

[tex]P(x)=ax^3+bx^2+cx+d[/tex]

It has a root [tex]x=1[/tex] of multiplicity 2, which means [tex](x-1)^2[/tex] divides [tex]P(x)[/tex] exactly, and it has a root of [tex]x=-3[/tex] of multiplicity 1 so that [tex]x+3[/tex] also is a factor. So

[tex]P(x)=a(x-1)^2(x+3)[/tex]

Expanding this gives

[tex]P(x)=a(x^3+x^2-5x+3)=ax^3+ax^2-5ax+3a[/tex]

[tex]\implies\begin{cases}a=b\\-5a=c\\3a=d\end{cases}[/tex]

The [tex]y[/tex]-intercept occurs for [tex]x=0[/tex], for which we have

Then

[tex]3a=d\implies a=0.7[/tex]

D. Inscribed angle

An inscribed angle has a vertex on the circumference. For any arc, every inscribed angle is exactly half of the central angle. In other words, if the central angle is [tex]x^{\circ}[/tex] and the inscribed angles is [tex]y^{\circ}[/tex], then it is true that:

The answer is:

It will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.

From the statement, we know that on Monday, bricklayers took 3 hours to lay a total of 4200 bricks.

So, we have that the rate of the four bricklayers is given by the following equation:

[tex]Production=Rate*Time\\\\Rate=\frac{Production}{time}[/tex]

[tex]Rate=\frac{4200bricks}{3hours}=\frac{1400bricks}{hour}[/tex]

Therefore, we have that the rate of the four bricklayers is 1400 bricks per hour, meaning that each bricklayer can lay 350 bricks per hour.

Now, to calculate how many hours it will take to the 2 bricklayers to lay a total of 3150, we need to divide the calculated rate (for bricklayers) by two, since there are only 2 bricklayers working on Tuesday.

So, calculating the time, we have:

[tex]Production=\frac{Rate}{2}*Time[/tex]

[tex]3150bricks=\frac{\frac{1400bricks}{hour}}{2}*Time[/tex]

[tex]3150bricks*2*\frac{1hour}{1400bricks}=Time[/tex]

[tex]6300bricks*\frac{1hour}{1400bricks}=Time[/tex]

[tex]Time=4.5hours[/tex]

Hence, we have that it will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.

Have a nice day!

Given the rate of work from Monday, each bricklayer can lay 350 bricks an hour. Therefore, 2 bricklayers can lay 700 bricks an hour. It will take them approximately 4.5 hours to lay 3150 bricks.

First, we need to find out the rate of work done by each bricklayer. On Monday, 4 bricklayers took 3 hours to lay a total of 4200 bricks. Therefore, each bricklayer can lay 4200 bricks divided by 4 bricklayers divided by 3 hours, which equals 350 bricks per hour. So, one bricklayer can lay 350 bricks an hour.

On Tuesday, there are only 2 bricklayers, and they need to lay a total of 3150 bricks. Since each bricklayer can lay 350 bricks an hour, two bricklayers can lay 700 bricks an hour. To find out the time it will take to lay 3150 bricks, we divide 3150 bricks by the 700 bricks that two bricklayers can lay in an hour. This equals to approximately 4.5 hours.

The required value of the wall after the window is made is 32 cubic feet.

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,
The total number of cubic feet in the wall before the window is made is,

6 feet (height) × 6 feet (width) = 36 cubic feet.

The window is 2 feet high and 2 feet wide, so its area is:

2 feet (height) × 2 feet (width) = 4 square feet.

To find the number of cubic feet removed to make the window, we simply multiply the area of the window by the depth of the wall, which is 1 foot:

4 square feet × 1 foot = 4 cubic feet.

Therefore, the total number of cubic feet in the wall after the window is made is,

36 cubic feet - 4 cubic feet = 32 cubic feet.

So the value of the wall after the window is made is 32 cubic feet.

10.00 was the markup

Ellen's markup on the rose bushes is calculated by subtracting the wholesale price from the retail price, resulting in a markup of $10.00.

The question asks to calculate the markup of rose bushes that were bought at a wholesale price and then sold at a retail price.

To find the markup, we subtract the wholesale price from the retail price: Retail Price - Wholesale Price = Markup.

In this case, Ellen bought the rose bushes at a wholesale price of $24 and the retail price was $34.

So, the markup calculation would be:

= $34 - $24 = $10.

Therefore, the markup on the rose bushes is $10.00.

Answer:

197,500

Step-by-step explanation:

Allison owes approximately $1,380.50 in prorated taxes and interest for the property she's closing on September 17.

To calculate the prorated taxes and interest that Allison owes, we need to break down the calculation into two parts: prorated property taxes and prorated interest.

1. **Prorated Property Taxes:**

  - Allison is closing on September 17, which means she will own the property for 106 days of the year (September 17 to December 31).

  - The seller has already paid $2,560.43 in property taxes for the entire year.

  - To calculate Allison's portion of the property taxes, we need to divide the seller's payment by the number of days in the year and then multiply by the number of days Allison will own the property.

Prorated Property Taxes = Seller's Property Tax Payment/

Days in Year × Days Allison Owns the Property

 [tex]\[ \text{Prorated Property Taxes} = \frac{2,560.43}{365} \times 106 \][/tex]

 [tex]\[ \text{Prorated Property Taxes} = \frac{2,560.43}{365} \times 106 = 741.12 \][/tex]

2. **Prorated Interest:**

  - Allison is taking out a 25-year fixed-rate mortgage for $185,000 at 6.25% interest.

  - To calculate the prorated interest, we need to find out how much interest Allison will owe for the remaining days of September.

 Daily Interest Rate [tex]$=\frac{\text { Annual Interest Rate }}{\text { Days in Year }}=\frac{6.25 \%}{365}$[/tex]

  Prorated Interest for September = [tex]Loan Amount $\times$ Daily Interest Rate $\times$ Number of Days in September[/tex]

  [tex]\[ \text{Prorated Interest for September} = 185,000 \times \frac{6.25\%}{365} \times 14 \][/tex]

 [tex]\[ \text{Prorated Interest for September} \approx 639.38 \][/tex]

Now, let's add up the prorated property taxes and prorated interest:

[tex]\[\text{Total Prorated Taxes and Interest} = \text{Prorated Property Taxes} + \text{Prorated Interest for September}\][/tex]

[tex]\[\text{Total Prorated Taxes and Interest} = 741.12 + 639.38\][/tex]

[tex]\[\text{Total Prorated Taxes and Interest} = 1380.50\][/tex]

So, Allison will owe approximately $1,380.50 in prorated taxes and interest.
