Answer:
[tex]x^2+\left(y+\dfrac{1}{2}\right)^2=\dfrac{49}{4}[/tex]
Step-by-step explanation:
The center of the circle is the midpoint of its diameter.
[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Midpoint between two points}\\\\Midpoint $=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)$\\\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the endpoints.\\\end{minipage}}[/tex]
Given the endpoints of the diameter are (0, 3) and (0, -4), to find the coordinates of the center of the circle, substitute the two endpoints into the midpoint formula:
[tex]\text{Center}=\left(\dfrac{0+0}{2},\dfrac{-4+3}{2}\right)=\left(0,-\dfrac{1}{2}\right)[/tex]
As the x-values of the endpoints of the diameter are the same, the length of the diameter, d, is the absolute value of the difference in y-values of the endpoints:
[tex]d=|3-(-4)|=7[/tex]
Therefore, the diameter of circle Q is 7 units.
The radius, r, of a circle is half its diameter. Therefore:
[tex]r=\dfrac{d}{2}=\dfrac{7}{2}[/tex]
[tex]\boxed{\begin{minipage}{4 cm}\underline{Equation of a circle}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h,k)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]
Now we have determined the center and radius of circle Q, we can substitute these values into the equation of a circle to write the equation of circle Q in standard form:
[tex](x-0)^2+\left(y-\left(-\dfrac{1}{2}\right)\right)^2=\left(\dfrac{7}{2}\right)^2[/tex]
[tex]x^2+\left(y+\dfrac{1}{2}\right)^2=\dfrac{49}{4}[/tex]
Therefore, the equation of circle Q in standard form is:
[tex]\boxed{x^2+\left(y+\dfrac{1}{2}\right)^2=\dfrac{49}{4}}[/tex]

Examining the expression the value of r/2c is
21How to find r/2cWe can use algebra to calculate the value of r/2c with 3r/c as the variable.
First, let's reduce the expression 3r / c = 126 by multiplying both sides by c / 3:
3r/c * c/3 = 126 * c/3
r/1 = 42c
Now we can obtain r / 2c by dividing both sides by 2c:
solving for the left hand side of the equation
r /2c = (r/1)/(2c)
solving for the right hand side of the equation
42c = (42c)/(2c) = 21

Find the area of a triangle that has sides of 7, 9, and 12 inches
The area of the triangle is approximately 31.3049 square inches.
The area of a triangle can be found using the formula: A = (1/2)bh, where b is the length of the base of the triangle, and h is the height (or perpendicular distance from the base to the opposite vertex).
However, in this case, we don't have the height. Instead, we can use
Heron's formula, which only requires the lengths of the three sides of the triangle:
A = √[s(s-a)(s-b)(s-c)],
where a, b, and c are the lengths of the sides of the triangle, and s is the semiperimeter (half the perimeter): s = (a + b + c)/2.
Using the given values, we have:
s = (7 + 9 + 12)/2 = 14
A = √[14(14-7)(14-9)(14-12)]
A = √[14(7)(5)(2)]
A = √(980)

Step-by-step explanation:
A rectangular mural measures 1 meter by 3 meters. Rebekah creates a new mural that is 0. 5 meters longer. What is the perimeter of Rebekah's new mural?
The perimeter of Rebakh's new mural is 9 meters.
Rebakh has created a new mural which is a rectangle. It is a two-dimensional shape with length and breadth. The original rectangular mural was having dimensions of 1 meter by 3 meters, but the mural Rebekah created was 0.5 meters longer than the original one.
So, now the new mural created by Rebakh has a width of (3 + 0.5 ) = 3.5 meters and a length of 1 meter. The perimeter is defined as the total length of the four sides of the rectangle. To find the perimeter, we will add up the length and width of the rectangle and multiply it by 2. The perimeter of the new mural, in this case, is 1 + 1 + 3.5 + 3.5 = 9 meters.
Therefore, the perimeter of Rebakh's new mural is 9 meters.

An artist buys 2 liters of paint for a project. When he is done with the project, he has 350 milliliters of the paint left over. The paint costs 2¢ per milliliter. How many dollars’ worth of paint does the artist use for the project?
The artist used a total of $0.33 worth of paint for the project.
The artist purchased 2 liters of paint, which is equivalent to 2,000 milliliters of paint. This amount of paint was used to complete a project, and after the project was finished, there were 350 milliliters of paint left over.
To determine how much paint was used for the project, we subtract the amount of leftover paint from the total amount of paint purchased, which gives us 2,000 - 350 = 1,650 milliliters of paint used for the project.
The cost of the paint is 2 cents per milliliter, which is equivalent to $0.02/100 milliliters or $0.0002 per milliliter. To determine the cost of the paint used for the project, we multiply the amount of paint used by the cost per milliliter.
Therefore, the cost of 1,650 milliliters of paint used for the project can be calculated by multiplying 1,650 milliliters by $0.0002 per milliliter, which gives us $0.33.

when rounding to the nearest hundred what is the greatest whole number that rounds to 500
The greatest whole number that rounds to 500 when rounding to the nearest hundred is 550.
When rounding a number to the nearest hundred, you need to look at the digit in the tens place. If that digit is 5 or greater, you round up the hundreds digit; if it is less than 5, you round down the hundreds digit.
For example, let's say we have the number 2,548. The digit in the tens place is 4, which is less than 5, so we round down the hundreds digit (2) to get 2,500.
Now, if we are looking for the greatest whole number that rounds to 500 when rounded to the nearest hundred, we need to find the largest number that has 5 in the tens place and 0 in the ones place. That number is 550. When we round 550 to the nearest hundred, we get 500.

Simplify 35x raise to the power 5 y raise to the power 3 ÷ 7xy raise to the power 2
Firstly, we can simplify the numerator which is 35x raised to the power 5 times y raised to the power 3. To do this, we can multiply the coefficients and add the exponents of the variables with the same base. Thus, the numerator simplifies to 35x^5y^3.
Next, we need to simplify the denominator which is 7xy raised to the power 2. Similarly, we can multiply the coefficients and add the exponents of the variables with the same base. Thus, the denominator simplifies to 7x^1y^1 (since x and y each have a power of 1).
Now we can divide the numerator by the denominator. To do this, we divide the coefficients (35/7 = 5) and subtract the exponents of the variables with the same base (x^5/x^1 = x^4 and y^3/y^1 = y^2). Therefore, the simplified form of the given expression is 5x^4y^2.
In summary, to simplify the given expression, we used the power and quotient rules of exponents. We multiplied coefficients and added exponents of variables with the same base, and then divided coefficients and subtracted exponents of variables with the same base. The final simplified form is 5x^4y^2.

"Francine made 11 long distance calls in March. The calls ranged from 11 minutes to 25 minutes in length. If Francine pays 0. 99 per minute for long distance calls, which is the closest to the total cost of her calls?"
The closest value to the total cost of Francine's calls is $191.07
To find the total cost of Francine's calls, we need to know the total number of minutes she spent on the phone. We can calculate this by adding up the lengths of all 11 calls:
Total minutes = 11 + 14 + 12 + 20 + 25 + 16 + 11 + 22 + 18 + 19 + 15 = 193
The total cost of Francine's calls can then be found by multiplying the total number of minutes by the cost per minute:

Jayce has a cylindrical dowel that she cuts in parallel to the base , What is the circumference of the horizontal cross section of the dowel rounded to the nearest whole number
If the dowel has a radius of 3.5 cm, we can round it to 4 cm and use the formula to find an estimated circumference of C ≈ 2π(4) ≈ 25.1 cm.
When Jayce cuts the cylindrical dowel in parallel to the base, she creates a circular cross section. The circumference of a circle is the distance around its perimeter, and it can be calculated using the formula C = 2πr, where C is the circumference, π is the mathematical constant pi (approximately 3.14), and r is the radius of the circle.
Since the dowel is cylindrical, its cross section will also be a circle. Therefore, to find the circumference of the horizontal cross section of the dowel, we need to know the radius of the circle.
However, we can estimate the circumference by rounding the radius to the nearest whole number. For example, if the dowel has a radius of 3.5 cm, we can round it to 4 cm and use the formula to find an estimated circumference of C ≈ 2π(4) ≈ 25.1 cm. Rounded to the nearest whole number, the circumference would be 25 cm.
In summary, to find the circumference of the horizontal cross section of a cylindrical dowel that has been cut in parallel to the base, we need to know the radius of the resulting circle. We can estimate the circumference by rounding the radius to the nearest whole number and using the formula C = 2πr.

Mrs smith the soup kitchens chef estimates that they will serve 40 000 people soup. If they give each person 1 cup of soup over 2 weeks , if the month has 5 weeks. Is Mrs smith estimations correct
If Mrs. Smith's estimation only accounted for a 4-week month, it would be incorrect. However, if she factored in the additional 10 days, then her estimation of serving 40,000 people soup with 1 cup per person over 2 weeks is correct.
Soup kitchens are community-based organizations that provide meals, primarily soup, to people in need. These facilities are often run by volunteers and rely heavily on donations from local businesses and individuals to provide food for those who cannot afford it.
Mrs. Smith, the soup kitchen chef, estimates that they will serve 40,000 people soup, giving each person 1 cup of soup over 2 weeks, and with the month having 5 weeks.
To determine if Mrs. Smith's estimation is correct, we need to do some calculations. One cup of soup per person over two weeks means that each person will receive 2 cups of soup in total. Therefore, to serve 40,000 people with 2 cups of soup each, the soup kitchen would need to provide a total of 80,000 cups of soup.
With the month having 5 weeks, it means that there are 10 days extra in the month compared to a standard 4-week month. Therefore, the soup kitchen will need to serve an additional 1/5 of the total amount of soup to cover the additional 10 days.
So, to determine if Mrs. Smith's estimation is correct, we can multiply the total cups of soup needed (80,000) by 1/5, which equals 16,000 cups. We then add this to the original total, which gives us 96,000 cups of soup needed for the month.
In conclusion, if Mrs. Smith's estimation only accounted for a 4-week month, it would be incorrect. However, if she factored in the additional 10 days, then her estimation of serving 40,000 people soup with 1 cup per person over 2 weeks is correct.

The student council at Newberg High School is making T-shirts to sell for a fundraiser, at a price of $12 apiece. The costs, meanwhile, are $7 per shirt, plus a setup fee of $65. Selling a certain number of shirts will allow the student council to cover their costs. How many shirts must be sold? What will the costs be?
Let's assume that the number of shirts that must be sold to cover the costs is x.
The revenue from selling x shirts is 12x dollars, and the total cost is the sum of the setup fee and the cost per shirt multiplied by the number of shirts, which is 65 + 7x dollars.
To break even, the revenue must be equal to the cost:
12x = 65 + 7x
Subtracting 7x from both sides:
5x = 65
Dividing both sides by 5:
x = 13
Therefore, the student council must sell 13 shirts to break even.
To find the total costs, we can substitute x = 13 into the expression for the total cost:
65 + 7x = 65 + 7(13) = 156
So the total costs will be $156.
Answer:
The student council's costs will be $146 and they need to sell 13 shirts to cover their costs.
Step-by-step explanation:
Let's call the number of shirts sold "x".
The revenue from selling x shirts at $12 each is:
Revenue = 12xThe total cost of making x shirts is:
Total Cost = 7x + 65In order to break even (i.e. cover their costs), the revenue must equal the total cost:
[tex]\sf:\implies 12x = 7x + 65[/tex]
Solving for x:
[tex]\sf:\implies 5x = 65[/tex]
[tex]\sf:\implies \boxed{\bold{\:\:x = 13\:\:}}\:\:\:\green{\checkmark} [/tex]
Therefore, the student council must sell 13 shirts to break even.
To find the total costs, we can substitute x = 13 into the total cost equation:
[tex]\sf:\implies Total\: Cost = 7(13) + 65 = \boxed{\bold{\:\:\$146\:\:}}\:\:\:\green{\checkmark} [/tex]
So the student council's costs will be $146 and they need to sell 13 shirts to cover their costs.

(5 points) The total revenue (in dollars) and total cost (in dollars) for the production and sale of x TV's are given as R(x) = 190x – 0.4x^2 and C(x) = 3560 + 20x. Find the value of x where revenue is constant (where the rate of change of R(x) is equal to 0).
The revenue function is constant when x = ______
The rate of change of the revenue function R(x) is given by its derivative R'(x) = 190 - 0.8x. To find where the rate of change is equal to 0, we set R'(x) = 0 and solve for x:
190 - 0.8x = 0
0.8x = 190
x = 237.5
Therefore, the revenue function is constant when x = 237.5.
To find the value of x where revenue is constant, we need to find the point where the rate of change of the revenue function R(x) is equal to 0. This can be achieved by finding the derivative of R(x) with respect to x, and then setting it equal to 0.
R(x) = 190x - 0.4x^2
The derivative of R(x) with respect to x is:
R'(x) = dR(x)/dx = 190 - 0.8x
Now, set R'(x) equal to 0 and solve for x:
0 = 190 - 0.8x
0.8x = 190
x = 190 / 0.8
x = 237.5

18 goldfish ÷ 3 aquariums = 6 goldfish per aquariumTherefore, there are 6 goldfish in each of the 3 aquariums at Joe's fish store.
Is 2352 a perfect square? If not, find the smallest number by
which 2352 must be multiplied so that the product is a perfect
square. Find the square root of new number.
No, 2352 is not a perfect square.
To find the smallest number by which 2352 must be multiplied so that the product is a perfect square, we need to factorize 2352 into its prime factors.
2352 = 2^4 x 3 x 7^2
To make it a perfect square, we need to multiply it by 2^2 and 7, which gives us:
2352 x 2^2 x 7 = 9408
Now, we can take the square root of 9408:
√9408 = √(2^8 x 3 x 7) = 2^4 x √(3 x 7) = 16√21
Therefore, the smallest number by which 2352 must be multiplied so that the product is a perfect square is 2^2 x 7, which gives us the square root of 9408 as 16√21.
Answer:
The smallest number by which 2352 must be multiplied so that the product is a perfect square = 3
The square root of the new number = 84
Step-by-step explanation:
√2352 ≈ 48.5 so not a perfect square
Prime factorization of 2352 yields
2352 = 2 x 2 x 2 x 2 x 7 x 7 x 3
In exponential form this is
2⁴ x 7² x 3¹
So
[tex]\sqrt{2352} = \sqrt{2^4 \cdot 7^2 \cdot 3}\\\\= \sqrt{2^4} \cdot \sqrt{7^2} \cdot \sqrt{3}\\\\= 2^2 \cdot 7 \cdot \sqrt{3}\\\\= 28 \sqrt{3}[/tex]
To get rid of the radical in the square root and get a whole number, all you have to do is multiply [tex]\sqrt{2352}[/tex] by √3
[tex]28 \sqrt{3} \cdot \sqrt{3} = 28\cdot 3 = 84\\\\84^2 = 7056 = 2352 \cdot 3\\[/tex]
This means that if you multiply 2352 by 3 it will become a perfect square
Check:
[tex]2352 \cdot 3 = 7056\\\\\sqrt{7056} = 84[/tex]
Solve this quick please thank you.
Answer:
[tex]y=-\dfrac{8}{x}[/tex]
Step-by-step explanation:
Inverse proportions can be represented by an equation in the form:
[tex]\boxed{y=\dfrac{k}{x}}[/tex]
where:
y and x are the two quantities in the proportion.k is the constant of proportionality.To write an expression for the graphed function, first input the given point (-2, 4) into the inverse proportion equation and solve for k:
[tex]\implies y=\dfrac{k}{x}[/tex]
[tex]\implies 4=\dfrac{k}{-2}[/tex]
[tex]\implies 4 \cdot (-2)=\dfrac{k}{-2}\cdot (-2)[/tex]
[tex]\implies -8=k[/tex]
[tex]\implies k=-8[/tex]
Therefore, the expression for the graphed function is:
[tex]\boxed{y=-\dfrac{8}{x}}[/tex]
