The evaluation using the equation of circle for the practice question is (x - 4)² + (y + 11)² = 256
What is the equation of the Circle Distance Formula?With respect to the distance formula, a point location in space (x,y) at a distance (r) from the origin is valid if [tex]\mathbf{\sqrt{x^2 + y^2} = r}[/tex]. Hence this refers to the equation of the circle centered at the origin.
For Conic Sections:
[tex]\mathbf{(x-h)^2 (y-k)^2 = r }[/tex]where;
center = (h,k)radius = rLet's assume we have a circle with C(4,-11) and radius r = 16;
Then, we have:
(x-h)² +(y -k)² = r²
(x-4)² + (y - (-11))² = 16²
(x - 4)² + (y + 11)² = 256

How can 100. ml of sodium hydroxide solution with a ph of 13.00 be converted to a sodium hydroxide solution with a ph of 12.00 ?
The solution can be evaporated such that only 10mL of the solution remains in that way, we can have a solution of pH 12.00.
What is pH?The pH refers to the degree of acidity or alkalinity of solution. We can obtain the concentration of each solution from the pH as follows;
At pH = 13;
[OH^-] = Antilog (-13) = 1 * 10^-13 M
At pH 12
[OH^-] = Antilog (-12) = 1 * 10^-12 M
Using the formula;
C1V1 =C2V2
1 * 10^-13 M * 100 mL = 1 * 10^-12 M * VmL
VmL = 1 * 10^-13 M * 100 mL/1 * 10^-12 M
VmL = 10mL

Determine the empirical formula of a compound containing 47. 37 grams of carbon, 10. 59 grams of hydrogen, and 42. 04 grams of oxygen. In an experiment, the molar mass of the compound was determined to be 228. 276 g/mol. What is the molecular formula of the compound? for both questions, show your work or explain how you determined the formulas by giving specific values used in calculations
Considering the definition of empirical formula, the empirical formula is C₃H₈O₂ and the molecular formula is C₉H₂₄O₆.
Definition of empirical formulaThe empirical formula is the simplest expression to represent a chemical compound, which indicates the elements that are present and the minimum proportion in whole numbers that exist between its atoms, that is, the subscripts of chemical formulas are reduced to the most integers. small as possible.
Empirical formula in this caseIn this case, you have:
Carbon (C): 47.37 gramsHydrogen (H): 10.59 gramsOxygen (O): 42.04 gramsThen it is possible to calculate the number of moles of each atom in the molecule, taking into account the corresponding molar mass:
Carbon (C): [tex]\frac{47.37 grams}{12 \frac{g}{mole} }[/tex]= 3.95 molesHydrogen (H): [tex]\frac{10.59 grams}{1 \frac{g}{mole} }[/tex]= 10.59 molesOxygen (O): [tex]\frac{42.04 grams}{16 \frac{g}{mole} }[/tex]= 2.63 molesThe empirical formula must be expressed using whole number relationships, for this the numbers of moles are divided by the smallest result of those obtained. In this case:
Carbon (C): [tex]\frac{3.95 moles}{2.63 moles }[/tex]= 1.5Hydrogen (H): [tex]\frac{10.59 moles}{2.63 moles }[/tex]= 4Oxygen (O): [tex]\frac{2.63 moles}{2.63 moles }[/tex]= 1Finally, since in the empirical formula the numbers of moles must be expressed in whole numbers, the ratio of atoms is multiplied by some number with which everything is obtained in simple whole numbers (in this case by 2):
Carbon (C): 1.5× 2= 3Hydrogen (H): 4× 2= 8Oxygen (O): 1× 2= 2Therefore the C: H: O mole ratio is 3: 8: 2
Finally, the empirical formula is C₃H₈O₂.
Molecular formulaTo obtain the molecular formula you must relate its molecular weight (PMc) with the molecular weight of the empirical formula (PMfe).
PMfe= PM (C₃H₈O₂)= 76 g/mole
The molar mass of the compound (PMc) was determined to be 228.276 g/mol. Dividing this mass PMc by the molar mass of the empirical formula PMfe gives:
228.276 g/mol ÷ 76 g/mole= 3
This means that in the molecular formula there are 3 unit formulas (empirical formulas), so it is necessary to multiply the number of all atoms by 3.
Then, the molecular formula is C₉H₂₄O₆.

Assuming it sells for $55.00 per share. Its effective annual (not nominal) rate of return is 7.47%.
Effective annual rate of returnUsing this formula
Effective annual rate of return=[1+(Preferred quarterly dividend+Preferred stock price]^Periods per year-1
Where:
Periods per year =4
Preferred quarterly dividend=$1.00
Preferred stock price=$55.00
Let plug in the formula
Effective annual rate of return = [1+ ($1.00/$55.00)]^4 - 1
Effective annual rate of return=(1+0.018181818)^4-1
Effective annual rate of return=(1.018181818)^4-1
Effective annual rate of return =1.0747-1

What are special cases envision algebra 1?
Envision Algebra 1 is one type of course that needs a good background on Pre-algebra functions. It is a type of algebra that starts from Linear Equations up to polynomials and factoring.
To solve for the above question, one has to separate the fraction on one side of the equation. This can be done by subtracting 4 from the two sides of the equation.
So, 3x-1/2 = 9 - 4
3x-1/2 = 5
The you have to multiply the 2 sides by using the denomiator 2 and so it will be:
3x-1 = 5 * 2
3x - 1 - 5 * 2
3x - 1 - 10

The amount applied to the principal for the third month of a 4-year loan of $50,000 at an interest rate of 10% per year with monthly payments is $865.71.
What is the amount of payment applied to the principal?The amount of the payment applied to the principal in any payment period is the total payment less the interest amount for the payment period.
For example, in this case, the periodic payment is $1,268.13. However, the interest amount for the month is $402.42 ($48,289.98 x 10% x 1/12).
The amount of the payment applied to the principal is $865.71 ($1,268.13 - $402.42).
This can be computed using an online finance calculator that calculates the periodic payment and prepares a monthly payment schedule as below.
Data and Calculations:N (# of periods) = 48 (4 x 12)
I/Y (Interest per year) = 10%
PV (Present Value) = $50,000
FV (Future Value) = $0
