The general equation for the circle that would pass through the given points would be x^2 + y^2 + x + (7/12)y - 315/576 = 0.

To find the general equation of the circle that passes through the points (-5, 0), (0, 4), and (2, 4), we can use the following equation for a circle:

(x - h)^2 + (y - k)^2 = r^2

Express the equation in terms of x, y, h, k, and r:

(x^2 - 2hx + h^2) + (y^2 - 2ky + k^2) = r^2

x^2 + y^2 - 2hx - 2ky + (h^2 + k^2 - r^2) = 0

Plug in the coordinates of the three points:

(-5)^2 + 0^2 - 2h(-5) - 2k(0) + (h^2 + k^2 - r^2) = 0

0^2 + 4^2 - 2h(0) - 2k(4) + (h^2 + k^2 - r^2) = 0

2^2 + 4^2 - 2h(2) - 2k(4) + (h^2 + k^2 - r^2) = 0

Substitute the values of h, k, and r^2:

(x - (-1/2))^2 + (y - (-7/24))^2 = 585/64

(x + 1/2)^2 + (y + 7/24)^2 = 585/64

(x^2 + x + 1/4) + (y^2 + (7/12)y + 49/576) = 585/64

x^2 + y^2 + x + (7/12)y + (1/4 + 49/576 - 585/64) = 0

x^2 + y^2 + x + (7/12)y - 315/576 = 0

The general equation for the circle that passes through the points (-5, 0), (0, 4), and (2, 4) is:

x^2 + y^2 + x + (7/12)y - 315/576 = 0

What is Graph ?

In mathematics, a graph is a visual representation of a set of objects, such as numbers or data points, and the relationships between them. Graphs can be used to represent a variety of mathematical concepts, including functions, sets of data, and geometric shapes.

The function f(x) = -|x| - 12 is a piecewise function. When x is greater than or equal to zero, the function simplifies to f(x) = -x - 12, and when x is less than zero, it simplifies to f(x) = x - 12.

If we graph both of these pieces separately, we get two straight lines that intersect at the point (0, -12), where the absolute value of x changes sign. The slope of both lines is -1, which means they are both downward sloping with a negative slope.

When we graph this function in the standard viewing window of -10 to 10, we can see the part of the graph where x is greater than or equal to zero, which is the left side of the graph, but the part where x is less than zero, which is the right side of the graph, is outside the viewing window.

The area of the rectangle is:

length x width

We need to first convert the length and width to the same units. We can convert them to twelfths of a meter, since both 6 and 4 are factors of 12.

Length = 3 and 2/6 meters = 3 x 12/6 + 2/6 = 18/6 + 2/6 = 20/6 = 10/3 twelfths of a meter

Width = 2 and 3/4 meters = 2 x 12/4 + 3/4 = 24/4 + 3/4 = 27/4 twelfths of a meter

Now we can find the area:

Area = length x width = (10/3) x (27/4) = 90/12 = 15/2 = 7.5 square meters

Therefore, the answer is option C) six and five-tenths m² (rounded to one decimal place).

Sascha receives 3.65% more percentage yield from the corporate bond than from dividends.

What is percentage yield?

To find out how much more percentage yield Sascha receives from the corporate bond than from dividends, we need to calculate the yield for each investment and compare them.

For the corporate bond:

Annual interest = 8.07% of $8,706 = $703.24

Yield = Annual interest / Bond value = $703.24 / $8,706 = 0.0809 or 8.09%

For the stock:

Dividend yield = Annual dividend / Stock value = $2 / $45 = 0.0444 or 4.44%

To find out the difference in percentage yield, we subtract the dividend yield from the bond yield:

8.09% - 4.44% = 3.65%

Therefore, Sascha receives 3.65% more percentage yield from the corporate bond than from dividends.

Answer: Let's first determine the number of hours SCVCS will be renting the Koger Center from 10:00 am to 3:00 pm. There are 5 hours between 10:00 am and 3:00 pm, so the rental time is:

Rental time = 5 hours

Using this information, we can write an equation to model the total cost of renting the Koger Center, y, as a function of the rental time, x, in hours:

y = 425x + 500

Here, the slope of the line represents the rental cost per hour, and the y-intercept represents the setup/cleanup fee.

Substituting x = 5 into the equation, we get:

y = 425(5) + 500

y = 2125 + 500

y = $2,625

Therefore, it will cost $2,625 to rent the Koger Center from 10:00 am to 3:00 pm.

So, the completed expression is:

y = 425x + 500

Substitute x = 5 into the equation.

It will cost $2625 to rent the Koger Center.

To find the total surface area of the box, we need to find the areas of all six faces and then add them up. Let's call the length, width, and height of the rectangular prism l, w, and h, respectively. Then the surface areas of the six faces are:

Top and bottom faces: 2lw (there are two identical faces)

Front and back faces: 2lh (again, two identical faces)

Left and right faces: 2wh (and two identical faces here as well)

So the total surface area is:

2lw + 2lh + 2wh

Substituting the given dimensions of the Freebie Cereal box, we have:

2(10)(8) + 2(10)(12) + 2(8)(12)

= 160 + 240 + 192

= 592

Therefore, the total surface area of the Freebie Cereal box is 592 square inches.

2.question

The lateral surface area of a rectangular prism is the sum of the areas of all its faces except for the top and bottom faces. In this case, the sandbox has dimensions of 4.5 feet by 5.4 feet by 2 feet.

The area of the front and back faces is 2 x 2 x 5.4 = 21.6 square feet.

The area of the left and right faces is 2 x 2 x 4.5 = 18 square feet.

So the total lateral surface area is 21.6 + 18 = 39.6 square feet.

Therefore, the closest answer to the lateral surface area of the sandbox is 39.6.

The maximum volume of the silo is V = SA/8(4-π), where SA is the surface area of the cylinder formed by the 2000 square feet of material.

We are given that 2000 square feet of material will be used to form a cylinder-shaped silo. We need to find the maximum volume of the silo.

Let's use the formula for the cylindrical surface area:

SA = πr^2 + 2πrh

We can solve for h in terms of r as follows:

SA = πr^2 + 2πrh

2πrh = SA - πr^2

h = (SA - πr^2) / (2πr)

Now, let's substitute this expression for h into the formula for the volume of a cylinder:

V = πr^2h

V = πr^2[(SA - πr^2) / (2πr)]

V = (SA - πr^2) / 2

We want to find the maximum volume, so we need to find the value of r that maximizes V. To do this, we can take the derivative of V with respect to r and set it equal to zero:

dV/dr = -πr/2 + SA/4π = 0

Solving for r, we get:

r = √(SA/(2π))

Substituting this value of r back into the expression for V, we get:

V = (SA - π(SA/(2π))^2) / 2

V = (SA - SA^2/(4π)) / 2

V = SA/8(4-π)

Therefore, the maximum volume of the silo is V = SA/8(4-π), where SA is the surface area of the cylinder formed by the 2000 square feet of material.

Answer: To solve the equation Three-fifths (30 x - 15) = 72, we can start by simplifying the left side of the equation by distributing the coefficient 3/5 to the terms inside the parenthesis:

Three-fifths (30 x - 15) = 72

18x - 9 = 72 (dividing both sides by 3/5)

Multiplying both sides of the equation by 5/3, we get:

10x - 5 = 24

10x = 29

x = 2.9

So the value of x for the original equation is x = 2.9.

Now we can test each option to see which equations have the same value of x:

18x - 15 = 72

18(2.9) - 15 = 40.2

This equation does not have the same value of x as the original equation.

50x - 25 = 72

50(2.9) - 25 = 125

This equation does not have the same value of x as the original equation.

18x - 9 = 72

18(2.9) - 9 = 40.2

This equation does not have the same value of x as the original equation.

3(6x - 3) = 72

3(6(2.9) - 3) = 72

This equation has the same value of x as the original equation.

x = 4.5

This equation does not have the same value of x as the original equation.

Therefore, the equations that have the same value of x as the original equation are:
