Find the center and radius of the circle represented by the equation below.
Answer:
centre = (5, - 6 ) , radius = 7
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
given
x² + y² - 10x + 12y + 12 = 0 ( subtract 12 from both sides )
x² + y² - 10x + 12y = - 12 ( collect terms in x/ y )
x² - 10x + y² + 12y = - 12
using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(- 5)x + 25 + y² + 2(6)y + 36 = - 12 + 25 + 36
(x - 5)² + (y + 6)² = 49 = 7² ← in standard form
with centre (5, - 6 ) and radius = 7
Answer:
Center = (5, -6)
Radius = 7
Step-by-step explanation:
To find the center and the radius of the circle represented by the given equation, rewrite the equation in standard form by completing the square.
To complete the square, begin by moving the constant to the right side of the equation and collecting like terms on the left side of the equation:
[tex]x^2-10x+y^2+12y=-12[/tex]
Add the square of half the coefficient of the term in x and the term in y to both sides of the equation:
[tex]x^2-10x+\left(\dfrac{-10}{2}\right)^2+y^2+12y+\left(\dfrac{12}{2}\right)^2=-12+\left(\dfrac{-10}{2}\right)^2+\left(\dfrac{12}{2}\right)^2[/tex]
Simplify:
[tex]x^2-10x+(-5)^2+y^2+12y+(6)^2=-12+(-5)^2+(6)^2[/tex]
[tex]x^2-10x+25+y^2+12y+36=-12+25+36[/tex]
[tex]x^2-10x+25+y^2+12y+36=49[/tex]
Factor the perfect square trinomials on the left side:
[tex](x-5)^2+(y+6)^2=49[/tex]
The standard equation of a circle is:
[tex]\boxed{(x-h)^2+(y-k)^2=r^2}[/tex]
where:
(h, k) is the center.r is the radius.Comparing this with the rewritten given equation, we get
[tex]h = 5[/tex][tex]k = -6[/tex][tex]r^2 = 49 \implies r=7[/tex]Therefore, the center of the circle is (5, -6) and its radius is r = 7.
y= -x^2 + x+ 12 in intercept form
Answer:
y = x + 12
Step-by-step explanation:
y = -x² + x + 12
y intercept form is, y = mx + c
where m = -b / a
the general quadratic equation is,
y = ax² + bx + c
thus, according to the question
m = -1 / -1 = 1
constant, c = 12
thus, the intercept form of the equation would be,
y = x + 12

The system has no solution. Option C is correct.
To solve the given system of equations using row operations, we can write the augmented matrix and perform Gaussian elimination. The augmented matrix for the system is:
1 1 -1 | 6
3 -1 1 | 2
1 4 2 | -34
We'll use row operations to transform the augmented matrix into row-echelon form or reduced row-echelon form. Let's proceed with the row operations:
R2 = R2 - 3R1:
1 1 -1 | 6
0 -4 4 | -16
1 4 2 | -34
R3 = R3 - R1:
1 1 -1 | 6
0 -4 4 | -16
0 3 3 | -40
R3 = R3 + (4/3)R2:
1 1 -1 | 6
0 -4 4 | -16
0 0 0 | -4
Now, we can rewrite the augmented matrix in equation form:
x + y - z = 6
-4y + 4z = -16
0 = -4
From the last equation, we can see that it leads to a contradiction (0 = -4), which means the system is inconsistent. Therefore, the system has no solution.
The correct answer is (C) This system has no solution.

Two models R1 and R2 are given for revenue (in millions of dollars) for a corporation. Both models are estimates of revenues from 2030 through 2035, with t = 0 corresponding to 2030.
R1 = 7.23 + 0.25t + 0.03t^2
R2 = 7.23 + 0.1t + 0.01t^2
How much more total revenue (in millions of dollars) does that model project over the six-year period ending at t = 5? (Round your answer to three decimal places.)
Step-by-step explanation:
To find the difference in total revenue projected by the two models over the six-year period ending at t = 5, we need to calculate the revenue for each model from t = 0 to t = 5 and subtract the results.
For R1:
R1 = 7.23 + 0.25t + 0.03t^2
Substituting t = 5:
R1(5) = 7.23 + 0.25(5) + 0.03(5^2)
R1(5) = 7.23 + 1.25 + 0.75
R1(5) = 9.23 + 0.75
R1(5) = 9.98 million dollars
For R2:
R2 = 7.23 + 0.1t + 0.01t^2
Substituting t = 5:
R2(5) = 7.23 + 0.1(5) + 0.01(5^2)
R2(5) = 7.23 + 0.5 + 0.25
R2(5) = 7.73 + 0.25
R2(5) = 7.98 million dollars
To find the difference, we subtract R2(5) from R1(5):
Difference = R1(5) - R2(5)
Difference = 9.98 - 7.98
Difference = 2 million dollars
Therefore, the model R1 projects 2 million dollars more in total revenue than R2 over the six-year period ending at t = 5.
Scores on the Wechsler Adult Intelligence Scale for the 20 to 34 age group are approximately Normally distributed with mean 110 and standard deviation 15. How high must a person score to be in the top 4% of all scores? (Round your answer to the nearest whole number, if necessary.)
Answer:
The person must score 136 to be in the top 5% of all scores in wechsler adult intelligence scale.
Step-by-step explanation:
What is defined as the normal distribution?
A normal distribution is a data set arrangement in which the majority of values cluster inside the center of the range and the remainder taper off symmetrically toward any extreme.
A histogram inside a normal distribution curve is sometimes used to design the curve.
The formula for the normal distribution is;
z = (x - μ)/σ
where,
z = z- score, taken fro table
Mean μ = 110
Standard deviation σ = 15
Sample mean x.
If we want to be in the top 5%, we must outperform 95% of the remaining scores. So we must investigate.
In with us standard normal probability table, look up 0.95 and get the Z score that corresponds to that.
z = 1.7
Put the value in formula ad find x.
1. 7 = (x - 110)/15
x = 25.5 + 110
x = 135.5
x = 136 (whole number)
Thus, the person must score 136 to be in the top 5% of all scores in wechsler adult intelligence scale.

Mean =
Standard deviation=
b. Find the z-score for each score in the sample
X= 5, z=
X= 0, z=
X= 4, z=
X= 5, z=
X= 1, z=
X= 2, z=
X= 4, z=
a. Mean = 3
Standard deviation = 2
b. The z-scores for each score in the sample are: 1, -1.5, 0.5, 1, -1, -0.5, 0.5.
a. To compute the mean and standard deviation for the sample, we follow these steps:
Calculate the mean (average)
Mean = (sum of all scores) / (number of scores)
Mean = (5 + 0 + 4 + 5 + 1 + 2 + 4) / 7
Mean = 21 / 7
Mean = 3
The mean of the sample is 3.
Calculate the standard deviation
The formula for standard deviation for a sample is given by:
Standard deviation = sqrt((sum of squared differences from the mean) / (number of scores - 1))
First, calculate the squared differences from the mean for each score:
(5 - 3)^2 = 4
(0 - 3)^2 = 9
(4 - 3)^2 = 1
(5 - 3)^2 = 4
(1 - 3)^2 = 4
(2 - 3)^2 = 1
(4 - 3)^2 = 1
Next, sum up these squared differences:
4 + 9 + 1 + 4 + 4 + 1 + 1 = 24
Now, divide this sum by (number of scores - 1):
24 / (7 - 1) = 24 / 6 = 4
Finally, take the square root of this result:
Standard deviation = sqrt(4) = 2
The standard deviation of the sample is 2.
b. To find the z-score for each score in the sample, we use the formula:
z = (X - Mean) / Standard deviation
For each score, we substitute the values into the formula:
X = 5, z = (5 - 3) / 2 = 2 / 2 = 1
X = 0, z = (0 - 3) / 2 = -3 / 2 = -1.5
X = 4, z = (4 - 3) / 2 = 1 / 2 = 0.5
X = 5, z = (5 - 3) / 2 = 2 / 2 = 1
X = 1, z = (1 - 3) / 2 = -2 / 2 = -1
X = 2, z = (2 - 3) / 2 = -1 / 2 = -0.5
X = 4, z = (4 - 3) / 2 = 1 / 2 = 0.5
The z-scores for each score in the sample are:
z = 1, z = -1.5, z = 0.5, z = 1, z = -1, z = -0.5, z = 0.5

Given the following diagram: We need to find the coordinates of triangle ABC, translate the triangle (-2, 5) and draw the new image on the grid above, and determine the amount each coordinate will move on the x-axis and y-axis during translation.
1. Coordinates of triangle ABC:A = (2, 6)B = (5, 8)C = (6, 3)2. Translation of triangle (-2, 5)The translation of a triangle can be done by adding or subtracting a constant value from the x-coordinates and y-coordinates of each vertex of the original triangle.
For example, if we want to translate a triangle by 3 units to the right and 2 units up, we would add 3 to the x-coordinates and add 2 to the y-coordinates of each vertex of the original triangle. Using this method, we can translate the triangle (-2, 5) as follows:
New coordinates of A = (2 + (-2), 6 + 5) = (0, 11)New coordinates of B = (5 + (-2), 8 + 5) = (3, 13)New coordinates of C = (6 + (-2), 3 + 5) = (4, 8)3.

Let X_1,…,X_n be a random sample. For S(X_1,…,X_n )=1/(1/n ∑_(i=1)^n▒〖(x_i-c)〗^2 ) , find its asymptotic distribution where EX^k=α_k.
The asymptotic distribution of the estimator S(X₁, ..., Xₙ) is a standard normal distribution, denoted as N(0, 1).
To find the asymptotic distribution of the estimator S(X₁, ..., Xₙ), we can use the Central Limit Theorem (CLT). However, we need some additional assumptions to apply the CLT, such as the finite variance of the random variables.
Given that E(Xᵢ^k) = αₖ for all k, we can assume that the random variables Xᵢ have a finite variance. Let's denote the variance of Xᵢ as Var(Xᵢ) = σ².
First, let's simplify the estimator S(X₁, ..., Xₙ):
S(X₁, ..., Xₙ) = 1 / (1/n ∑ᵢ (Xᵢ - c)²)
Notice that the numerator is a constant and doesn't affect the asymptotic distribution. So, we can focus on analyzing the denominator.
Let's calculate the expected value and variance of the denominator:
E[1/n ∑ᵢ (Xᵢ - c)²] = 1/n ∑ᵢ E[(Xᵢ - c)²] = 1/n ∑ᵢ (Var(Xᵢ) + E[Xᵢ]² - 2cE[Xᵢ] + c²)
= 1/n (nσ² + α₁ - 2cα₁ + c²) (using the fact that E[Xᵢ] = α₁ for all i)
Var[1/n ∑ᵢ (Xᵢ - c)²] = 1/n² ∑ᵢ Var[(Xᵢ - c)²] = 1/n² ∑ᵢ (Var(Xᵢ - c)²) = 1/n² ∑ᵢ (Var(Xᵢ))
= 1/n² (nσ²) = σ²/n
Now, let's apply the CLT. According to the CLT, if we have a sequence of independent and identically distributed random variables with a finite mean (μ) and a finite variance (σ²), the sample mean (in this case, our denominator) converges in distribution to a standard normal distribution as the sample size approaches infinity.
Therefore, as n approaches infinity, the asymptotic distribution of S(X₁, ..., Xₙ) will follow a standard normal distribution.

prove that the lim x→−3 (10 − 2x) = 16
Answer:
Proving that the limit of the equation 10 - 2x as x approaches -3 is 16 involves using the definition of a limit.
Here's how you would approach it:
Let epsilon be a small positive number. We want to find a value of delta such that if x is within a distance of delta from -3, then 10 - 2x is within a distance of epsilon from 16.
So, we start with:
|10 - 2x - 16| < epsilon
Simplifying,
|-2x - 6| < epsilon
And using the reverse triangle inequality,
|2x + 6| > ||2x| - |6||
Now, we can choose a value for delta such that if x is within delta of -3, then |2x + 6| is within delta + 6 of |-6| = 6.
So,
||2x| - |6|| < epsilon
and therefore:
|2x - 6| < epsilon
Choosing delta = epsilon/2, we can prove that:
0 < |x + 3| < delta -> |2x - 6| < epsilon
Therefore, we have proved that the limit of 10 - 2x as x approaches -3 is 16 using the definition of a limit.

The density of lead is 11,300 kg/[tex]m^3[/tex], which means that lead is a dense material with a significant mass per unit volume.
To find the density of lead, we can use the formula:
Density = Mass / Volume
Given that the mass of lead is 3,390 kg and the volume is 0.3 [tex]m^3[/tex], we can substitute these values into the formula:
Density = 3,390 kg / 0.3[tex]m^3[/tex]
To simplify the calculation, we divide the mass by the volume:
Density = 11,300 kg/[tex]m^3[/tex]
Therefore, the density of lead is 11,300 kg/[tex]m^3[/tex].
Density is a physical property of a substance that describes how much mass is packed into a given volume. In this case, the density of lead tells us that for every cubic meter of lead, there are 11,300 kilograms of mass.

If the expenditure of a person is 75% of his income and his income tax which is 13% of his income is $585. What is his expenditure?
The person's expenditure is $1,755. (30 words)
To find the expenditure, we need to determine the person's income first. Since the income tax is 13% of the income and is given as $585, we can calculate the income. Dividing the income tax by the tax rate gives us the income. So, $585 divided by 0.13 equals $4,500, which is the person's income.
Now, we can calculate the expenditure. Given that the expenditure is 75% of the income, we can multiply the income by 0.75 to find the expenditure. So, $4,500 multiplied by 0.75 equals $3,375. Therefore, the person's expenditure is $3,375. (120 words)
In summary, the person's expenditure is $3,375. To find this, we first determined the person's income by dividing the given income tax of $585 by the tax rate of 13%, resulting in an income of $4,500.
Then, we calculated the expenditure by multiplying the income by 0.75 since the expenditure is stated to be 75% of the income. Thus, the person's expenditure is $3,375.

v2=v02+2ax ; solve for x.
To solve for x in the equation v2 = v0^2 + 2ax, we can rearrange the equation to isolate x:
x = (v2 - v0^2) / (2a)
In this equation, v2 represents the final velocity, v0 is the initial velocity, a is the acceleration, and x is the displacement. By substituting the given values of v2, v0, and a into the equation, we can calculate the value of x.
The equation v2 = v0^2 + 2ax is derived from the kinematic equation that relates displacement, velocity, acceleration, and time. By isolating x, we can determine the displacement.
The equation represents the final velocity (v2) as the sum of the square of the initial velocity (v0^2) and the product of twice the acceleration (2a) and displacement (x).
To solve for x, we subtract v0^2 from v2 to obtain (v2 - v0^2), and then divide this difference by 2a. This yields the value of x, which represents the displacement.
By substituting the provided values of v2, v0, and a, we can evaluate the expression and calculate the value of x. This equation is commonly used in physics and mechanics to determine the displacement of an object given its initial and final velocities and acceleration.
