A circle is the set of all points that are the same distance from one given point. Find an example that contradicts this definition. How would you change the definition to make it more accurate?
An example that contradicts this definition would be an ellipse that set all points such that the sum of the distances between the point and two other fixed points (called foci) is constant.
What is the equation of a circle?The equation of a circle with center (h,k) and radius r is :
r² = (x−h)² + (y−k)²
A circle is defined as the set of all points that are the same distance from one given point, called the center of the circle. An example that contradicts this definition would be an ellipse, which is defined as the set of all points such that the sum of the distances between the point and two other fixed points (called foci) is constant.
An ellipse is not a circle since all points of an ellipse are not equidistant to the center point
To make the definition more accurate, it could be modified to say "A circle is defined as the set of all points that are a fixed distance from one given point, called the center of the circle." or "A circle is defined as the set of all points such that the distance between the point and the center is constant"

What are the potential solutions of In(x^2-25)=0?
Answer:
[tex] x =\pm \sqrt{26}[/tex]
Step-by-step explanation:
Given :-
ln ( x² - 25 ) = 0And we need to find the potential solutions of it. The given equation is the logarithm of x² - 25 to the base e . e is Euler's Number here. So it can be written as ,
Equation :-
[tex]\implies log_e {(x^2-25)}= 0 [/tex]
In general :-
If we have a logarithmic equation as ,[tex]\implies log_a b = c [/tex]
Then this can be written as ,
[tex]\implies a^c = b [/tex]
In a similar way we can write the given equation as ,
[tex]\implies e^0 = x^2 - 25 [/tex]
Now also we know that [tex]a^0 = 1[/tex] Therefore , the equation becomes ,[tex]\implies 1 = x^2 - 25 \\\\\implies x^2 = 25 + 1 \\\\\implies x^2 = 26 \\\\\implies x =\sqrt{26} \\\\\implies x = \pm \sqrt{ 26}[/tex]
Hence the Solution of the given equation is ±√26.

g(x)=\sqrt{x} -5
what is the range and domain
Answer:
Function Domain and Range
g(x)=\sqrt{x} -5
what is the range and domain
To find the range of g(x), we can substitute a few values of x into the expression for g(x) to see what the output is. For example, when x = 0, g(x) = sqrt(0) - 5 = 0 - 5 = -5. When x = 1, g(x) = sqrt(1) - 5 = 1 - 5 = -4. When x = 2, g(x) = sqrt(2) - 5 = 1.4142 - 5 = -3.5858.
As we can see, the output of g(x) is always a negative number for any value of x in the domain. Therefore, the range of g(x) is the set of all negative real numbers, or (-infinity, 0).
So, the domain of g(x) is all real numbers x such that x >= 0, and the range of g(x) is all negative real numbers (-infinity, 0).

What is volume?Volume is a degree of occupied three-dimensional area. its miles are regularly quantified numerically with the use of SI-derived devices or with the aid of various imperial devices. The definition of the period is interrelated with the extent.
here, we have,
Density is the substance's mass according to a unit of volume. The image most customarily used for density is ρ, even though the Latin letter D also can be used. Mathematically, density is described as mass divided with the aid of the extent
Mass of aluminum boat = 16.5 gram
Volume = 425 cm³
Density = mass/ volume
= 16.5/425
= 0.039 gcm⁻³
The density of water and boat must be equal or more in order of sinks.
The density of water = 1 gcm⁻³
1 gcm⁻³ = mass × 0.039
mass = 1/ 0.039
mass = 25.64 g
A total of 25.64 grams of mass can be added.
mass of each penny = 2.5 g
Therefore the total number of pennies that can be added is = 25.64 /2.5
= 10.256
Taking the whole number = 10 pennies can be added o the boat before it sinks

Which of the following are the factors of the equation x 2 3x − 4 0?
(A) (x+4)(x-1)=0 is the proper factors form of the given equation x²+3x-4=0.
What are the factors?A factor is a number that completely divides another number.
To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.
So, we have the equation:
x²+ 3x - 4 = 0
By dividing the center term, this quadratic equation can be reduced to its simplest form.
The result of dividing the middle word is:
x² + 4x - x - 4 = 0
One way to spell it is as:
x (x + 4) - 1 (x + 4) = 0
Now, we obtain:
(x + 4) (x - 1) = 0
Therefore, (A) (x+4)(x-1)=0 is the proper factors form of the given equation x²+3x-4=0.

A 6. 0 kg bowling ball traveling at 2 m/s strikes a 1. 5 kg bowling pin. Describe and compare the forces that act on the bowling ball and the bowling pin
during the collision.
By using formula and solving, Force of impact (pin) = Change in momentum (pin) / Time of collision = 12 kg*m/s / t
What is collision?A collision is an event in which two or more objects come into contact with each other. In physics, a collision is defined as a rapid and forceful interaction between two or more objects that causes a transfer of energy. Collisions can be elastic or inelastic, depending on whether or not the total kinetic energy of the objects is conserved.
What is force?Force is a physical quantity that describes the interaction between two or more objects. It is a vector quantity, meaning it has both magnitude and direction. Forces can cause an object to accelerate, change its shape, or change its direction of motion. Forces can be categorized into different types, such as contact forces, which act when two objects are in contact, and non-contact forces, which act at a distance. Some examples of non-contact forces are gravitational force, electric force, and magnetic force.
To calculate the force of impact on the bowling ball and bowling pin during the collision, you can use the formula:
Force of Impact = Change in momentum / Time of collision
The change in momentum is given by the formula:
Change in momentum = Final momentum - Initial momentum
The initial momentum of the 6 kg bowling ball traveling at 2 m/s is:
Initial momentum (ball) = 6 kg * 2 m/s = 12 kg*m/s
The final momentum of the bowling ball can be calculated using the conservation of momentum principle, which states that the total momentum of the system remains constant before and after the collision. In this case, since the bowling pin is moving after the collision and the bowling ball is not, the final momentum of the bowling ball is zero.
Final momentum (ball) = 0
Change in momentum (ball) = Final momentum (ball) - Initial momentum (ball) = 0 - 12 kgm/s = -12 kgm/s
The force of impact on the bowling ball is:Force of impact (ball) = Change in momentum (ball) / Time of collision = -12 kg*m/s / t (t is the time of collision, assuming it's a short time)
Similarly, the initial momentum of the 1.5 kg bowling pin at rest is:
Initial momentum (pin) = 1.5 kg * 0 m/s = 0 kg*m/s
The final momentum of the bowling pin can be calculated using the conservation of momentum principle, which states that the total momentum of the system remains constant before and after the collision.
Final momentum (pin) = Initial momentum (ball) = 12 kg*m/s
Change in momentum (pin) = Final momentum (pin) - Initial momentum (pin) = 12 kgm/s - 0 kgm/s = 12 kg*m/s
The force of impact on the bowling pin is:
Force of impact (pin) = Change in momentum (pin) / Time of collision = 12 kg*m/s / t

A right cylinder has a radius of 12 units and a height of 15 units. What is the total surface area, in units squared?
Answer:
2034.72 units²
Step-by-step explanation:
Formula for surface area of a cylinder is:
2πrh + 2πr²
The radius is 12 and the height is 15, so we plug it in:
2π(12·15) + 2π(12)²
2π(12·15) + 2π(12)²=2034.72.
Determine and state an equation of the line perpendicular to the line 5x-4y=10 and passing through the point (5,12)
The equation of the line perpendicular to the line 5x-4y=10 and passing through the point (5,12) is y = 4x/5 + 8.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
Given:
The line 5x-4y=10.
Simplifying,
y = (-5/4)x + 5/2
Comparing with the slope-intercept form,
y = mx + b,
where m is the slope and b is y-intercept.
The slope is = -5/4
The slope of the perpendicular line,
= negative reciprocal of the slope of the line where the line is perpendicular.
= 4/5
So, the line:
If a line passes through one point (x₁ ,y₁) and have slope m,
then the equation of line is
y - y₁ = m (x - x₁)
y - 12 = (4/5)(x-5)
y = 4x/5 + 8
Therefore, the equation of the line is y = 4x/5 + 8

Is 12 16 20 a right triangle?
No, 12 16 20 is not a right triangle. In order to be a right triangle, one side must be the same as the square root of the sum of the squares of the other two sides. In this case, the hypotenuse (side 20) is not equal to the square root of 12^2 + 16^2 which is 20.
No, 12 16 20 is not a right triangle. To determine whether or not something is a right triangle, we need to use the Pythagorean Theorem. This theorem states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the hypotenuse is side 20, and the other two sides are 12 and 16. When we calculate the square root of 12^2 + 16^2, we get 20, which does not match the length of the hypotenuse. Therefore, 12 16 20 is not a right triangle.
