What is the distance from center formula?
From the centre formula the distance is between two points in a plane.
A mathematical calculation known as the distance formula is used to calculate the separation between two points on a plane. The Pythagorean theorem, which asserts that the square of the length of the hypotenuse in a right triangle equals the sum of the squares of the lengths of the legs, is the source of the distance formula which is the side opposite the right angle.
The distance formula is frequently shown as: d = √((x2 - x1)² + (y2 - y1)²). The first point's coordinates are x1 and y1, the second point's coordinates are x2 and y2, and d is the distance between the two points. It's crucial to keep in mind that this method only works when the two points are in a 2D plane.

Elliot added the two equations and the result was 2x = 38. Solve the equation. How many of each type of book does elliot have? fiction books nonfiction books.
For each type of book, Elliott has 19 fiction books and 7 nonfiction books.
To solve for the number of fiction books (x), we can use the first equation of the system: x + y = 26. We know that the number of nonfiction books (y) can be represented by x - 12 (from the second equation of the system: x - y = 12).
So we can substitute x - 12 for y in the first equation:
x + (x - 12) = 26Combining like terms:
2x - 12 = 26Adding 12 to both sides:
2x = 38Dividing both sides by 2:
x = 19Therefore, Elliot has 19 fiction books.
To solve for the number of nonfiction books (y), we can use the first equation of the system: x + y = 26 and input the value of x:
x + y = 26y = 26 - xy = 26 -19y = 7Therefore, Elliot has 7 nonfiction books.

Jump To The Flag
Bob is trying to reach a flag that's some height above the ground. In his attempt to reach the flag, Bob can make any number of jumps up the rock wall where it's mounted. He can only move up the wall though, and he must end at exactly the height of the flag. There are 2 types of jumps:
1. A jump of height 1.
2. A jump of height j ;
Determine the minimum number of jumps it will take Bob to reach the flag's height exactly
The minimum number of jumps required to reach the flag's height is 3.
Let n be the height of the flag. We can use a recursive approach to determine the minimum number of jumps it takes to reach the flag's height.
For n = 0, it takes 0 jumps to reach the flag's height.
For n = 1, it takes 1 jump to reach the flag's height.
For n > 1, we can calculate the minimum number of jumps using the following equation:
minJumps(n) = 1 + min(minJumps(n-1), minJumps(n-j))
Where minJumps(x) is the minimum number of jumps required to reach the flag's height from ground level x.
For example, if the flag's height is 5 and Bob can jump a height of 2, the minimum number of jumps required to reach the flag's height is 3.
minJumps(5) = 1 + min(minJumps(4), minJumps(3))
= 1 + min(1 + min(minJumps(3), minJumps(2)), 1 + minJumps(2))
= 1 + min(1 + 1, 1 + 1)
= 3
Therefore, the minimum number of jumps required to reach the flag's height is 3.

The price of a TV is 540 omr
In a sale it is reduced by 35%
Work out the sale price.
If you get stuck, consider drawing a diagram.
You may want to use a calculator to work out 35% of
540 first...
To calculate the sale price, we need to find out how much the TV is discounted by, which we can do by multiplying the original price by the percentage discount (expressed as a decimal).
35% of the original price can be expressed as 0.35.
so,
Discount = 540 omr * 0.35 = 189 omr
To find the sale price, we can subtract the discount from the original price:
Sale price = Original price - Discount
Sale price = 540 omr - 189 omr
So the sale price is 351 omr.

f(x) = ax^2 + bx + c,
where
a, b, and c are constants and x is the variable.
The graph of a quadratic function is a parabola that opens either upward or downward, depending on the value of a. The vertex of the parabola is the point (h, k), where h = -b/2a and k = f(h). The roots of the quadratic function, or the x-coordinates of the points where the parabola crosses the x-axis, can be found using the quadratic formula: x = (-b ± √(b^2 - 4ac)) / 2a.
The range of a quadratic function in the form of y = ax^(2) + bx + c is all real numbers for a ≠ 0, and for a = 0,

A rectangular solid (with a square base) has a surface area of 181. 5 square centimeters. Find the dimensions that will result in a solid with maximum volume.
The maximum volume is 63.75 cubic cm. The rectangular is kind of shape that has lenght and width.
To find the dimensions of the rectangular solid that will result in a maximum volume, we can use the formula for the surface area of a rectangular solid, which is:
Surface Area = 2lw + 2lh + 2wh
where l is the length, w is the width (which is the same as the base of the square), and h is the height.
We can set up an equation using this formula, with the given surface area:
181.5 = 2lw + 2lh + 2wh
To find the maximum volume, we can take the derivative of the volume equation and set it equal to 0, then solve for the value of the variable.
The volume of the rectangular solid is V = lwh
The derivative of V with respect to l is : dV/dl = wh
The derivative of V with respect to w is : dV/dw = lh
The derivative of V with respect to h is : dV/dh = lw
Therefore, the maximum volume occurs when dV/dl = 0, dV/dw = 0 and dV/dh = 0
Since the base of the rectangular solid is a square, we know that l = w
If we substitute this value into the equation for the surface area, we get:
181.5 = 2l^2 + 2lh
Solving for h in terms of l, we get:
h = (181.5 - 2l^2) / (2l)
We can now differentiate this equation with respect to l, and set it equal to 0, then solve for l:
[tex]\frac{dV}{dl} = (2lh + l^2h - 2l^3) / l = 0\\2l(181.5 - 2l^2) + l^3 = 0\\2l(181.5 - 2l^2) = -l^3\\2(181.5 - 2l^2) = -l^2\\363 - 4l^2 = -l^2\\l^2 = 181.5 / 2\\l = \sqrt{\frac{181.5}{2} } \\I = \sqrt{90.75} \\I = 3.5[/tex]
So the dimensions that will result in a maximum volume are:
length (l) = 3.5 cm
width (w) = 3.5 cm
height (h) = (181.5 - 23.53.5) / (2*3.5) = 5 cm
The maximum volume is V = lwh = 3.53.55 = 63.75 cubic cm
