find the circle and radius of the circle x2 + y2 +12x +6y +20=0
To find the circle and radius of equation x2 + y2 +12x +6y +20=0, we need to complete the square for both x and y terms.
First, we can simplify the equation by rearranging the constant term to the right-hand side:
x^2 + y^2 + 12x + 6y = -20
Next, we can complete the square for the x-terms by adding (12/2)^2 = 36 to both sides of the equation:
x^2 + 12x + 36 + y^2 + 6y = -20 + 36
Simplifying further:
(x + 6)^2 + (y + 3)^2 = 13
This is now in the standard form of a circle: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius.
So the center of the circle is (-6, -3) and the radius is the square root of 13. Therefore, the equation x^2 + y^2 + 12x + 6y + 20 = 0 represents a circle with center (-6, -3) and radius sqrt(13).
what verbal (written) scale from inches to feet would represent a map whose representative fraction (rf) scale is 1:48,000? (1 foot
If the representative fraction scale is 1:48000, then the verbal scale from inches to feet is 1 inch represents 0.00025 feet.
We have to find the verbal (written) scale from inches to feet that represents a map with a representative-fraction (RF) scale of 1:48,000,
We use the formula:
⇒ Verbal scale = RF × Inches per foot,
We know that the RF scale is 1:48,000, which means that one unit on the map represents 48,000 units in the real world.
There are 12 inches in a foot,
So, we can convert the verbal scale to inches-per-foot by dividing by 12:
⇒ Inches per foot = (Verbal scale)/(12),
⇒ Inches per foot = (1/48000) × (12/1) = 0.00025
Therefore, the verbal scale from inches to feet is : 1 inch represents 0.00025 feet.

The length of arc TU is approximately 0.3935 cm.
Calculation of circle ?
To find the length of arc TU, we first need to determine the measure of angle TAU. Since TV is a diameter, we know that angle TSV is a right angle (90 degrees). Since S is the midpoint of TV, angle TSU is half of angle TSV, which means angle TSU is 45 degrees (90/2 = 45). Therefore, angle TAU is the complement of angle TSU, which is 90 - 45 = 45 degrees.
Next, we need to use the formula for the length of an arc of a circle, which is L = rθ, where L is the length of the arc, r is the radius of the circle, and θ is the measure of the central angle of the arc in radians. Since we have the measure of the central angle in degrees, we need to convert it to radians by multiplying by π/180.
The radius of the circle is half the diameter, which is 0.5 cm. Therefore, we have:
L = rθ
L = 0.5 × (45 × π/180)
L = 0.5 × (0.25π)
L = 0.125π
To get a numerical value, we can use an approximation of π, such as 3.14. Therefore, the length of arc TU is approximately:
L ≈ 0.125π ≈ 0.125 × 3.14 ≈ 0.3935 cm
So the length of arc TU is approximately 0.3935 cm.
The formula of a circle relates its radius, diameter, and circumference.
The diameter of a circle is the distance across the circle passing through its center, and is given by:
D = 2r
where r is the radius of the circle.
The circumference of a circle is the distance around its outer edge, and is given by:
C = 2πr
where r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14159.
The area of a circle is the region enclosed by the circle, and is given by:
A = πr²
where r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14159.
These formulas can be used to solve various problems related to circles, such as finding the area, circumference, radius, or diameter of a circle, given one or more of these values.

What is a piecewise function?A piecewise function comprises of two or more functions that set the definition or rule of the function based on the specified interval.
10. The piecewise function indicates;
p(x) = -3·x + 7 if x ≤ 3
When x = 3, p(x) = -3 × 3 + 7 = -2
When x approaches -∞, p(x) → ∞
The domain and range in the interval x ≤ 3 are;
Domain = (-∞, 3]
Range = [-2, ∞)
P(x) = x if 3 < x < 5
The domain and range in the interval 3 < x < 5 are;
Domain; (3, 5)
Range; (3, 5)
P(x) = -1 if x ≥ 5
The domain and range in the interval x ≥ 5 are;
Domain; [5, ∞)
Range; -1
Therefore;
D = (-∞, ∞)
R = [-2, ∞)
11. k(x) = x + 4 if x < -1
k(x) = 5 if -1 < x < 2
k(x) = -(1/2)·x + 1 if x ≥ 2
The domain and range in the interval x < -1 are;
Domain; (-∞, -1)
Range; (-∞, 3)
The domain and range in the interval -1 < x < 2 are;
Domain; (-1, 2)
Range; 5
The domain and range in the interval x ≥ 2 are;
Domain; [2, ∞)
Range; (-∞, 0]
The function is undefined for x = -1
The domain and range of the piecewise function is therefore;
D; (-∞, -1) ∪ (-1, ∞)
R; (-∞, 3) ∪ [5, 5]
12. The points on the graph where x ≤ 0 are; (0, 2), and (-5, 0)

Therefore; f(x) = (2/5)·x + 4 if x ≤ 0
The points on the graph when x > 0 are; (0, -5), and (5, 0)
The slope is; 5/5 = 1, the y-intercept is; (0, -5)
The equation is therefore; y = x - 5
Therefore; f(x) = x - 5 if x > 0
The piecewise function is therefore;
[tex]f(x) =\begin{cases} \frac{2}{5}\cdot x +4 & \text{ if } x\leq 0 \\x -5 & \text{ if } x > 0 \end{cases}[/tex]
13. The points on the graph when x < -1 are; (-1, -1), and (-2, 0)
The slope is; 1/-1 = -1
The equation is; y - 0 = -1×(x - (-2)) = -x - 2
y = -x - 2
Therefore, f(x) = -x - 2 if x < -1
The points on the graph when -1 < x < 3 are; (-1, 5), and (3, 5)
The slope is; 0, the equation is; y = 5
Therefore; f(x) = 5 if -1 < x < 3
The points on the graph when 3 ≤ x < ∞ are; (3, -1), and (5, -5)
The slope is; -4/2 = -2
The equation is; y - (-1) = -2×(x - 3) = -2·x + 6
y = -2·x + 6 - 1 = -2·x + 5
y = -2·x + 5
Therefore; f(x) = -2·x + 5 if 3 ≤ x < ∞
The piecewise function is therefore;
[tex]f(x) =\begin{cases} -x -2 & \text{ if } x < -1 \\5 & \text{ if } -1 < x < 3\\-2\cdot x + 5 & \text{ if } 3 \leq x < \infty \end{cases}[/tex]
14. The functions in the piecewise function graph are;
f(x) = -2 if x < -4
The points in the interval -4 < x ≤ 2 are; (-4, 2), (0, 4)and (2, 5)
The slope is; 3/6 = 1/2
The y-intercept is; (0, 4)
The function is therefore; f(x) = (1/2)·x + 4
The points in the interval 2 < x < ∞ are; (2, -2), and (4, -5)
The slope is; -3/2 = -1.5
The equation is; y - (-2) = (-3/2) × (x - 2) = -x + 2
y = -x + 2 - 2 = -x

The equation of line L1 is y=2x+1 The equation of Line L2 is 4y-8x+1=0
show these are parallel
To check if Line L1 and Line L2 are parallel, we need to check if their slopes are equal.
Given L1 is y=2x+1
The slope of L1 is the coefficient of x, which is 2.
since L1 is in the form of y=mx+c where m is the slope
Given L2 is 4y-8x+1=0
To find the slope of L2, we need to rearrange it to slope-intercept form
y = mx + b, where m is the slope and b is the y-intercept.
4y - 8x + 1 = 0
4y = 8x - 1
y = 2x - 1/4
Now the above equation is in the form of y=mx+c
The slope of L2 is also 2.
Since both lines have the same slope, we can conclude that they are parallel. Therefore, we can say that Line L1 and Line L2 are parallel.

do you remember how to find a discontinuity of a rational function? how is it different from an asymptote
the discontinuities of a rational function involves finding the values of x that make the denominator equal to zero, while finding the asymptotes of a rational function involves examining the behavior of the function as x approaches certain values.
Describe the function.
There will be questions on every subject, including created and real places as well as algebraic variable design, on the midterm test. a schematic illustrating the connections between various components that work together to produce the same outcome. A service is made up of many unique parts that work together to produce unique outcomes for each input.
To find the discontinuities of a rational function, we need to determine where the function is undefined. In general, a rational function is a function of the form:
f(x) = p(x) / q(x)
where p(x) and q(x) are polynomials in x, and q(x) is not the zero polynomial. The rational function f(x) is undefined at any value of x that makes the denominator q(x) equal to zero, since division by zero is undefined.
Therefore, to find the discontinuities of a rational function, we need to solve the equation q(x) = 0. The values of x that make q(x) equal to zero are called the "zeros" or "roots" of the denominator q(x). These values of x are the discontinuity points of the function, since the function is undefined at those points.
On the other hand, to find the asymptotes of a rational function, we need to examine the behavior of the function as x approaches certain values. In general, a rational function may have three types of asymptotes: horizontal, vertical, and oblique (also called slant).
Vertical asymptotes occur when the function approaches positive or negative infinity as x approaches a certain value, typically where the denominator q(x) equals zero.
Horizontal asymptotes occur when the function approaches a constant value as x approaches positive or negative infinity.
Oblique asymptotes occur when the degree of the numerator is exactly one greater than the degree of the denominator. In this case, the function approaches a straight line (i.e., a slant asymptote) as x approaches positive or negative infinity.
To summarize, finding the discontinuities of a rational function involves finding the values of x that make the denominator equal to zero, while finding the asymptotes of a rational function involves examining the behavior of the function as x approaches certain values.

7. Writing Write a paragraph proof showing that if
5(2x-3)= 25, then x = 4.
Answer:
We know that when 5(2x-3) = 25 x = 4 because when you plug 4 back into the equation you get 25=25. To solve this equation first you will distribute 5 into 2x -3 you will then get 10x-15 = 25. Then you will add 15 to both sides and get 10x = 40, next divide 10 from both sides and you will get x=4. To check this you can plug 4 back into the equation so it will look like this. 5(2(4)-3) = 25, first you will solve what is in the parenthesis, you will set 5(5)=25. Then multiply 5 by 5 and you will get 25=25. This proves that when 5(2x-3) = 25 x = 4

Where T is the time it takes for both persons working together to complete the job, t1 is the time it takes for the first person to complete the job alone, and t2 is the time it takes for the second person to complete the job alone.
Plugging in the given values, we get:
1 / T = 1 / 5 + 1 / 10
Simplifying the right side, we get:
1 / T = 3 / 10
Multiplying both sides by 10T, we get:
10 = 3T
Dividing both sides by 3, we get:
T = 10 / 3 = 3.33 hours
Therefore, it will take approximately 3.33 hours for both persons working together to complete the job.

Describe the transformation of g(c)=3(2)^x as it relates to the parent function f(x)=2^x
That g(x) is a vertical stretch of f(x) by a factor of 3, followed by a vertical shift of 3 units upward.
The function g(x) = 3[tex]2^{x}[/tex] is a transformation of the parent function f(x) = [tex]2^{x}[/tex]. Specifically, g(x) is obtained by first stretching f(x) vertically by a factor of 3, and then shifting it upward by some amount.
To understand this transformation more clearly, consider the effect of changing the value of x on both functions. For the parent function f(x) = [tex]2^{x}[/tex], increasing x by 1 corresponds to multiplying the output (y-value) by 2. For example, if we evaluate f(x) at x=0, we get f(0) = [tex]2^{0}[/tex] = 1, and if we evaluate it at x=1, we get f(1) =[tex]2^{1}[/tex] = 2, which is double the value of f(0).
Now, let's consider the function g(x) =3[tex]2^{x}[/tex] . When we evaluate g(x) at x=0, we get g(0) = 3[tex](2)^{0}[/tex] = 3, which is triple the value of f(0). Similarly, when we evaluate g(x) at x=1, we get g(1) = 3[tex](2)^{1}[/tex] = 6, which is triple the value of f(1). This shows that g(x) is a vertical stretch of f(x) by a factor of 3.
Finally, notice that the function g(x) has the same shape as f(x), but is shifted upward by an amount of 3 units. We can see this by comparing the graphs of the two functions. The graph of f(x) starts at the point (0,1) and increases rapidly as x gets larger. The graph of g(x) starts at the point (0,3) and increases at the same rate as f(x). This shows that g(x) is a vertical stretch of f(x) by a factor of 3, followed by a vertical shift of 3 units upward.

An outline of a city map is shown. The population of the city is 23,023 people. What is the population density of the city?
The proportion of individuals to land area is known as the population density. The Population Density is 148.38 people/m².
What is Population Density?The proportion of individuals to land area is known as the population density. People per square kilometre is the metric. The term "population density" refers to the number of people in a given area, typically expressed as "per square kilometre" or "per square mile," and may include or exclude features like glaciers or bodies of water.
The number of members of a species in a given geographic area is known as population density. Demographic data can be measured and examined in relation to infrastructure, environments, and human health using population density data.
Population Density = the nation's population ÷ Area of country
Population of country = 23,023
Area of country = (18*8)+(4*5)
= 164 m²
Population Density= 23023÷164
= 148.38 people/m²
