Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options. The radius of the circle is 3 units. The center of the circle lies on the x-axis. The center of the circle lies on the y-axis. The standard form of the equation is (x – 1)² + y² = 3. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
The true statements are:
The radius of the circle is 3 units.The standard form of the equation is (x – 1)² + y² = 3.The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.What is circle?A circle is a closed, two-dimensional shape where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the middle.
To identify the true statements, we can first rewrite the given equation of the circle in standard form:
x² - 2x + y² = 8
Completing the square, we get:
(x - 1)² + y² = 9
Now we can identify the true statements:
The radius of the circle is 3 units. (True, the equation is in standard form (x-1)² + y² = 3²)The center of the circle lies on the x-axis. (False, the center is (1,0))The center of the circle lies on the y-axis. (False, the center is not on the y-axis)The standard form of the equation is (x – 1)² + y² = 3. (True, as shown above)The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9. (True, both circles have a radius of 3)Therefore, the true statements are:
The radius of the circle is 3 units.The standard form of the equation is (x – 1)² + y² = 3.The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.Learn more about circle on:

The numeric values for this problem are given as follows:
g(-1) = -2.g(2) = 0.g(3) = 0.5.How to obtain the numeric values of the function?The function in this problem is a piecewise function, meaning that it has different definitions based on the input x of the function.
For x between -2 and 2, the function is defined as follows:
g(x) = -(x - 1)² + 2.
Hence the numeric value at x = -1 is given as follows:
g(-1) = -(-1 - 1)² + 2 = -4 + 2 = -2.
For x at x = 2 and greater, the function is given as follows:
g(x) = 0.5x - 1.
Hence the numeric values at x = 2 and x = 3 are given as follows:
g(2) = 0.5(2) - 1 = 0.g(3) = 0.5(3) - 1 = 0.5.A similar problem, also featuring numeric values of a function, is given at brainly.com/question/28367050

Step-by-step explanation:
You want to identify the polynomial that has terms written in descending order of their degree.
DegreeThe degree of a term is the exponent of x in that term. In the given polynomial, the term degrees are 3, 1, 7, 0, 11.
When these are put into descending order, that order is ...
11, 7, 3, 1, 0

A boat’s velocity, measured in meters per second, is described by vector b⇀=⟨3,4⟩. In two or more complete sentences explain how to find the speed of the boat and the direction it is traveling in standard position. In your final answer, include all of your calculations.
for this i got 5 m/s and 413 but i need to know more about it. i have to factor in WHERE the vector is before calculating the direction- and i dont quite understand how to do that so help would be MUCH appreciated <3
Answer: Velocity is a vector, so it has a magnitude and direction.
Speed is its magnitude, which is obtained from
|〈-3, 4〉 m/s| = √((-3 m/s)² + (4 m/s)²) = √(25 m²/s²) = 5 m/s
Its direction is an angle θ made with the positive horizontal axis, satisfying
tan(θ) = (4 m/s) / (-3 m/s) = -4/3 → θ = arctan(-4/3) + 180°n
where n is any integer. Now you have to consider that the x coordinate is negative and the y coordinate is positive, so 〈-3, 4〉 points into the second quadrant, and we get an angle there for n = 1 of about
θ ≈ 126.87°
Alternatively, you can use the vector 〈1, 0〉 in place of the axis, then compute the angle by relating it to the dot product, so θ is such that
〈-3, 4〉 • 〈1, 0〉 = |〈-3, 4〉| |〈1, 0〉| cos(θ)
(-3)•1 + 4•0 = √((-3)² + 4²) • √(1² + 0²) cos(θ)
-3/5 = cos(θ) → θ = arccos(-3/5) + 360°n
where again, n is any integer, and we get the same solution θ ≈ 126.87° in the second quadrant when n = 0.

Answer:
option 1 is the answer
Step-by-step explanation:
IN A CIRCLE , THE TANGENT IS THE PERPENDICULAR TO THE RADIUS DRAWN TO THE POINT OF CONTACT
SO AC ⊥ BC
ie angle ACB= 90 degree
therefore in triangle ABC , ACB = 90 DEGREE
By applying pythagorus theorem ,
AB^2 = AC^2 + BC^2
5^2 = r^2 + 3^2
25 -9 = r^2
16 = r^2
r = square root o f 16

Domain: (-∞, -2) ∪ (-2, ∞) ∪ (1, ∞)
Holes: (1, -2/3).
Vertical asymptote: x = -2.
Horizontal asymptote: y = 2.
What is a rational expression?In Mathematics, a rational expression simply refers to a type of expression which is expressed as a fraction. In this exercise, we would factorize the numerator and denominator for this rational expression as follows;
Numerator = 2x² - 6x + 4
Numerator = 2(x² - 3x + 2)
By using the sum-product pattern, we have the following:
Numerator = 2(x² - x - 2x + 2)
Numerator = 2(x - 2)(x - 1)
Denominator = x² + x - 2 = (x - 1)(x + 2).
f(x) = (2x² - 6x + 4)/(x² + x - 2) = [2(x - 2)(x - 1)]/[(x - 1)(x + 2)]
f(x) = 2(x - 2)/(x + 2)

The total amount of sugar that was consumed by Kylie in the past nine (9) days is equal to 3 units of sugar.
What is a line plot?In Mathematics and Statistics, a line plot refers a type of graph that is used to graphically represent a data set above a number line, while using crosses, dots, or any other mathematical symbol.
Based on the data and information provided in the line plot shown in the image attached above, we can calculate the total amount of sugar that was consumed by Kylie in the past nine (9) days as follows:
Total sugar consumed = (1/8 + 1/8 + 1/8) + 1/4 + (3/8 + 3/8 + 3/8) + (5/8 + 5/8)
Total sugar consumed = 3(1/8) + 1/4 + 3(3/8) + 2(5/8)
Total sugar consumed = 3/8 + 1/4 + 9/8 + 10/8
Total sugar consumed = 22/8 + 1/4
Total sugar consumed = (22 + 2)/8
Total sugar consumed = 24/8
Total sugar consumed = 3 units of sugar.

What would the height need to be for this curve to be a density curve?
1/5

For a curve to be a density curve, it must meet certain conditions such as it should be non-negative, and the area under the curve should equal 1. Furthermore, the curve should be continuous and smooth, and there should be no values outside the range of the data.
Let's see how the height would need to be for this curve to be a density curve.A density curve is a statistical representation of the distribution of a dataset or population. Density curves are used to describe the distribution of continuous data and provide a visual representation of the likelihood of an event occurring within a specific range of values. It helps to determine the proportion of data that falls within a given range of values. A density curve is used to provide a graphical representation of data without showing the individual data points.To be a density curve, a curve must have the following properties:The curve should be non-negative.The area under the curve should be equal to 1.The curve should be smooth and continuous.There should be no values outside the range of the data.From the above properties, we can conclude that the height required for a curve to be a density curve depends on the data that the curve represents. As long as the curve meets the above conditions, it can be considered a density curve. So, there is no specific height required for a curve to be a density curve. The height of the curve can vary depending on the range of the data and the distribution of the data.For such more question on properties

How do I find x & z? I know y is 43?
The values of x and z both are given by 137.
We know that the sum of linear pair of angles is 180.
Here x and 43 are the linear pair of angles. So,
x + 43 = 180
x = 180 - 43
x = 137
Now x and z are vertically opposite angles, so they are equal.
So, z = x = 137
Hence the values of x and z both are 137.
