Write and equation in standard form of a circle with a center at -10 -4 and having the (4, -2) on the circle.
Given:
Center of circle, (h, k) = (-10, -4)
Point the circle passes through ==> (4, -2)
Let's write the equation of the circle in standard form.
Apply the standard form of a circle equation:
\((x-h)^2+(y-k)^2=r^2\)Where:
(h, k) is the radius.
r is the radius of the circle.
To find the radius, let's find the distance between the points using the distance between points:
\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1})^2\)Where:
(x1, y1) ==> (-10, -4)
(x2, y2) ==> (4, -2)
Thus, we have:
\(\begin{gathered} d=\sqrt{(4-(-10)^2+(-2-(-4))^2} \\ \\ d=\sqrt{(4+10)^2+(-2+4)^2} \\ \\ d=\sqrt{14^2+2^2} \\ \\ d=\sqrt{196+4} \\ \\ d=\sqrt{200} \\ \\ d=14.14 \end{gathered}\)Hence, we have:
• Center, (h, k) = (-10, -4)
,• Radius of the circle = √200
Therefore, the equation of the circle is:
\(\begin{gathered} (x-(-10))^2+(y-(-4))^2=\sqrt{200^2} \\ \\ (x+10)^2+(y+4)^2=200 \end{gathered}\)ANSWER:
\((x+10)^2+(y+4)^2=200\)Find the value of α, where −90^0≤α≤90^0
sinα=−0.2273
(Round to the nearest tenth as needed.)
The value of α, where −90° ≤ α ≤ 90° and sinα = -0.2273, is approximately -13.1°.
The sine function relates an angle to the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle. To find the value of α, we can use the inverse sine function, also known as arcsine or sin⁻¹.
Using a calculator or a mathematical software, we can calculate the inverse sine of -0.2273, which gives us approximately -13.1°. Since the range of α is specified to be between -90° and 90°, the closest value within this range is -13.1°. Therefore, α ≈ -13.1°.

Three eighths of the 48 roses were red. (a) How many roses were red? (b) How many roses were not red? (c) What fraction of the roses were not red?
Answer:
A. 18 roses were red.
B. 30 roses were not red.
C. 5/8 were not red.
Step-by-step explanation:
In order to do this question, we first need a calculator. Then, we take three eighths and divide them on the calculator to get:
3 divided by 8 = 0.375.
Then, on the calculator again, we take the 48 roses and find the percentage of the roses that were red, by multiplying it by 0.375:
0.375 x 48 = 18.
A. 18 roses were red.
Now, for the next question, how many roses were not red. We take the 48 roses and subtract it from the roses that were red, which were 18 roses:
48 - 18 = 30.
B. 30 roses were not red.
Now, to find the fraction of the roses that weren't red. We take the 30 roses that weren't red and divide it by the total amount of 48 roses:
30 divided by 48 = 0.625.
In order to make 0.625 into a fraction, we take the higher, but lowest 100th place we can make for 0.625:
625/1,000.
Now, we simplify it:
625 divided by 5 = 125
1,000 divided by 5 = 200
Now, we have 125/200.
Simplify more:
125 divided by 5 = 25
200 divided by 5 = 40
Once more:
25 divided by 5 = 5
40 divided by 5 = 8
Our final fraction is 5/8.
C. The fraction of the roses that were not red are 5/8.

explain which properties of equality you used when solving the equation from part a to determine the mystery weight.
To solve the equation in part a and determine the mystery weight, we used the following properties of equality:
Addition property: This property states that if we add the same number to both sides of an equation, the equality is preserved. In this case, we added 23 grams to both sides of the equation to isolate the variable.
Subtraction property: This property states that if we subtract the same number from both sides of an equation, the equality is preserved. In this case, we subtracted 8 grams from both sides of the equation to isolate the variable.
Multiplication property: This property states that if we multiply both sides of an equation by the same number, the equality is preserved. In this case, we multiplied both sides of the equation by 3 to isolate the variable.
Division property: This property states that if we divide both sides of an equation by the same number (excluding 0), the equality is preserved. In this case, we divided both sides of the equation by 2 to isolate the variable.
By using these properties of equality, we were able to manipulate the equation and isolate the variable to determine the mystery weight.

Amani earns 41 dollars per week working part-time at a book store. She makes one dollar more for each book that she sells. The amount, A (in dollars), that
Amani earns in a week if she sells b books is given by the following.
A=41+b
How much does Amani earn in a week if she sells 18 books?
Amani earns 59 dollars in a week if she sells 18 books.
Amani earns a base amount of $41 per week for working part-time at the bookstore. In addition to that, she earns an extra dollar for each book she sells. The equation A = 41 + b represents her total earnings, where A represents the amount she earns and b represents the number of books she sells.
To find out how much Amani earns in a week if she sells 18 books, we substitute the value of b (18) into the equation:
A = 41 + 18
This simplifies to:
A = 59
Therefore, if Amani sells 18 books in a week, she will earn $59.

calculate the ph of a solution prepared by mixing 15.0ml of 0.10m naoh
The pH of the solution prepared by mixing 15.0 mL of 0.10 M NaOH is 13.
What is the pH of a solution obtained by combining 15.0 mL of 0.10 M NaOH?The pH of a solution is a measure of its acidity or alkalinity. It is determined by the concentration of hydrogen ions (H+) in the solution. In this case, we are given 15.0 mL of 0.10 M NaOH, which is a strong base. NaOH dissociates completely in water, producing hydroxide ions (OH-). Since NaOH is a strong base, it readily donates OH- ions to the solution. The concentration of OH- ions can be calculated using the volume and molarity of NaOH given.
To find the pH, we can use the equation: pH = -log[H+]. Since NaOH is a strong base, it consumes H+ ions in the solution, resulting in a low concentration of H+ ions. Thus, the pH is high.
The concentration of OH- ions can be calculated as follows:
0.10 M NaOH × 15.0 mL = 1.5 mmol OH-
To convert this to concentration (M), we need to consider the total volume of the solution. If the final volume is 15.0 mL (assuming no significant change), the concentration of OH- is 1.5 mmol / 15.0 mL = 0.10 M.
The pH is calculated as follows:
pOH = -log[OH-] = -log[0.10] = 1.
Since pH + pOH = 14, the pH of the solution is 14 - 1 = 13.

Answer:
∠B = 82°
Step-by-step explanation:
(see attached for reference)
recall the property that an exterior angle of a triangle is equal to the sum of its two remote interior angles.
in our case, the exterior angle is obtuse ∠A = 143°
the two remote interior angles are ∠C and ∠B
hence according to our definition above:
143° = ∠C + ∠B (we are given that ∠C =61°)
hence
143° = 61° + ∠B
143° - 61° = ∠B
∠B = 82°

maximize 3x + y subject to −x + y + u. = 1. 2x + y+. +v = 4 x, y, u, v ≥ 0.
The maximum value of 3x + y is 5/3, which is achieved when x = 1/3 and y = 4/3.
We can solve this optimization problem using the simplex method. First, we convert the problem to standard form:
Maximize: 3x + y + 0u + 0v + 0s1 + 0s2
Subject to:
-x + y + u + s1 = 1
2x + y + v + s2 = 4
x, y, u, v, s1, s2 ≥ 0
We then construct the initial simplex tableau:
| 1 -1 1 0 1 0 | 1
| 2 1 0 1 0 4 | 4
| 3 1 0 0 0 0 | 0
The pivot element is the entry in the first row and first column, which is 1. We use row operations to make all other entries in the first column zero. We subtract row 1 from row 2, and subtract 3 times row 1 from row 3:
| 1 -1 1 0 1 0 | 1
| 0 3 -1 1 -1 4 | 3
| 0 4 -3 0 -3 0 | -3
The new pivot element is the entry in the second row and second column, which is 3. We use row operations to make all other entries in the second column zero. We divide row 2 by 3, and subtract 4 times row 2 from row 3:
| 1 0 1/3 -1/3 2/3 4/3 | 5/3
| 0 1 -1/3 1/3 -1/3 4/3 | 1
| 0 0 -1/3 -4/3 -5/3 -16/3 | -5
All entries in the objective row are positive or zero, so we have found the optimal solution. The maximum value of 3x + y is 5/3, which is achieved when x = 1/3 and y = 4/3.

A rectangular piece of paper with length 39 cm and width 20 cm has two semicircles cut out of it, as shown below.Find the area of the paper that remains. Use the value 3.14 for π , and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
The area of the piece of paper is 466 cm²
Step-by-step explanation:
First you would want to find the area of the rectangle
39x20=780 cm²
Both semi-circles are the same, so you can just find the area of the whole circle
The diameter is 20 cm so you would use 10 as the radius
A=πr²
A=3.14x10²
A=3.14x100
A=314
Then you have to subtract the area of the circle from the area of the rectangle.
780-314=466
The area of the piece of paper is 466 cm²
