The endpoints of a diameter of a circle a(-1,1) and b(3,3). what is the length of the radius
Answers
If we determine the distance from one point to the second point, we get the length of the diameter. This is calculated through the equation,
D= sqrt ((x2 – x1)^2 + (y2 – y1)^2)
Substituting the known values,
D = sqrt ((-1 – 3)^2 + (1 – 3)^2)
D = 4.47
The length of the radius is half that of the diameter. Hence, the radius is,
R = 4.47 /2 = 2.236
Answer: r = 2.24

How do you verify that a hexagon formed by A=(0,0), B=(2,1), C=(3,3), D=(2,5), E=(0,4) and F=(-1,2) is equiangular? (I already know that it is equilateral)
Answers
To verify that the hexagon is equiangular, calculate the slopes and angles of all sides using the coordinates of the vertices.
Explanation:To verify that a hexagon is equiangular, we need to show that all interior angles of the hexagon are congruent. We can calculate the angles using the coordinates of the vertices A, B, C, D, E, and F.
Calculate the slope of each side of the hexagon. For example, for side AB with points A(0,0) and B(2,1), the slope is (1-0)/(2-0) = 1/2.Use the slope to find the angle using the formula arctan(slope). For side AB, the angle is arctan(1/2) = 26.57 degrees.Repeat steps 1 and 2 for all sides of the hexagon.If all six angles are equal, then the hexagon is equiangular.Learn more about Equiangular Hexagon here:https://brainly.com/question/31803879

Given that f(a+b)= f(a) + f(b) and f(x) is always positive, what os the value of f(0)?
Answers
[1] We know that f(a+b) = f(a) + f(b). Therefore, f(0+0) = f(0) + f(0). In other words, f(0) = f(0) + f(0). Subtracting, we see, f(0) - f(0) = f(0) or 0 = f(0).
[2] So, what's the problem? We found the answer, f(0) = 0, right? Maybe, but the second rule says that f(x) is always positive. However, f(0) = 0 is not positive!
Since there is a contradiction, we must either conclude that the single value f(0) does not exist, or that the entire function f(x) does not exist.
To fix this, we could instead say that "f(x) is always nonnegative" and then we would be safe.
Given the following functions f(x) and g(x), describe the changes (horizontal shifts, vertical shifts, etc.) to the graph of g(x) with respect to the graph of f(x).
f ( x ) = | x | g ( x ) = - | x + 3 | -2

Answers
This is a cryptarithm problem where every unique letter represents a unique digit. Given that 'u' equals 5, we would navigate the problem by dividing numbers out front and subtracting the exponents.
Explanation:This question is about a form of a cryptarithm. Cryptarithms are mathematical puzzles where the digits are replaced by letters of the alphabet or other symbols. If the same letter appears more than once, it represents the same digit each time. Your question implies that each letter corresponds to a unique digit and that division is involved. Therefore, we need to figure out which numbers are represented by the remaining letters. You've already been given that 'u' represents 5. Since there isn't a complete problem provided, I can't offer a step by step guide on how to solve it. However, I can suggest to you to start the cryptarithm solution by dividing numbers out front and subtracting the exponents.

round 999.999 to the nearest tenth
Answers
to the left of the point you start with tenths then hundredths and so on
Reasoning:
For the number 999.999, the 0.9 is the tenth's digit.
Since the next number is 5 or greater, we round the 0.9 up. Now 0.9 rounded up is 1, so that takes away the decimals and adds one to the ones place value.
Since we are adding 1 to 9, it becomes 10, meaning the following 9 becomes a ten as well.
All said and done, it becomes 1000 from the rounding.

what transformation has changed the parent function f(x) =log3x to its new appearance shown in the graph below
Answers
log_3(1) asks "3^? = 1," which we know is 0. So, log_3(1) = 0, which means (1,0) is a point on the graph for the parent function.
log_3(3) asks "3^? = 3" which we know is 1. So, log_3(3) = 1, which means (3,1) is a point on the graph for the parent function.
Now, we look at the graph they gave us and we see that our two points have moved upward 2 units. Now, (1,2) and (3,3). The transformation appears to be f(x) + 2, as you have selected.

If the length of the rectangle is twice the width and the perimeter of the rectangle is 30 cm find its area
Answers
Length is twice the width, twice meaning two times and we know that the width is x so length = 2x.
The perimeter is the sum of all the sides or width + width + length + length which is equal to x + x + 2x + 2x by substituting x for width and 2x for length. We know that x is really 1x since 1 times anything is that anything.
So the perimeter can be written as 1x + 1x + 2x + 2x which we are told is equally 42 meters. We reduce the equation by collecting all terms that have the same variables so we get (1 + 1 + 2 + 2 )x = 42. Adding the collected terms together we get 6x = 42. Now we solve for x by dividing both sides of the equation by six. Whatever we do to one side we have to do to the other so the equation remains balanced. So 6x divide by 6 is 1x or we can just say x, and 42 is divided 6 giving us 7. So x = 7. Going back to our original stated facts width = x = 7 and length = twice the width or 2x = 2 (7) =14. So
width = 7 meters
legth = 14 meters
We can double check this since we know the formular for the perimeter = width + width + length + length = 7 + 7 + 14 + 14 = 42.

Let the number of regular containers the plane can transport be x and the number of super-size containers the plane can transport be y, then
Given that one super-size container takes up the space of 3 regular containers, i.e. y = 3x and that the capacity of the plane is 15 regular containers.
When the ship is not carrying any super-sized container, it can carry up to 15 regular containers and when the ship is not carrying any regular containers it can carry up to 5 super-sized containers.
Therefore, the inequality to model the number of regular and super-size containers the plane can transport is given by

What is parabola ?
The graph of a quadratic equation in two variables (y=ax² + bx + c) is called a parabola.
Parabola has the equation ,
y = ax² + bx + c --------- Equation (1)
At point (−1, 1)
x = -1 and y = 1
Substitute the values of x and y in the equation (1).
i.e., y = ax² + bx + c
1 = a × (-1)² + b× (-1) + c
1 = a × (1) - b + c
1 = a - b + c
Thus, in x-y plane at point (1,-1) , equation will be , a - b + c = 1.

Find the average value of f over region
d. f(x, y) = 4x sin(y), d is enclosed by the curves y = 0, y = x2, and x = 7.
Answers
The question involves finding the average value of function f(x, y) = 4x sin(y) over a particular region. This is done using a double integral to integrate the function over the region and divide by the area of that region. The area of the region is determined using the given boundaries.
Explanation:The subject of this question is calculus, specifically dealing with a double integral to find the average value of a function over the specified region. The given function is f(x, y) = 4x sin(y), and the region d is enclosed by the curves y = 0, y = x^2, and x = 7.
To find the average value of function f over the region d, you should use the formula for the average value of a function of two variables. This is given by: Avg = (1/Area(D)) ∫∫_D f(x, y) dA
Before we can use this formula, we need to find the area of region D. This can be obtained as a simple integral from the given boundaries: Area(D) = ∫ from 0 to 7 dx ∫ from 0 to x^2 dy = ∫ from 0 to 7 x^2 dx = [x^3/3]_0^7 = 343/3
We can then proceed with the double integration by applying the appropriate limits. This is a more complex process that requires substitutions and careful calculation. After evaluating the average value, you should get a numerical solution.
