One endpoint of a line segment has coordinates represented by (x+6, 1/3y). The midpoint of the line segment is (2,−5). How are the coordinates of the other endpoint expressed in terms of x and y?
Answer:
The coordinates of the other endpoint are [tex]B(x,y) = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex].
Step-by-step explanation:
Let [tex]AB[/tex] a line segment in which [tex]M[/tex] is the midpoint. If both [tex]A[/tex] and [tex]M[/tex] are given, then we determine the location of [tex]B[/tex] from definition of midpoint. That is:
[tex]\frac{1}{2}\cdot \vec A + \frac{1}{2}\cdot \vec B = \vec M[/tex] (Eq. 1)
Where:
[tex]\vec A[/tex], [tex]\vec B[/tex] - Endpoints with respect to origin, dimensionless.
[tex]\vec M[/tex] - Midpoint with respect to origin, dimensionless.
[tex]\vec A + \vec B = 2\cdot \vec M[/tex]
[tex]\vec B = 2\cdot \vec M - \vec A[/tex]
If we know that [tex]A(x, y) = \left(x+6,\frac{1}{3}\cdot y \right)[/tex] and [tex]M(x, y) = (2,-5)[/tex], then the coordinates of [tex]\vec B[/tex] are:
[tex]\vec B = 2\cdot (2,-5)-\left(x+6,\frac{1}{3}\cdot y \right)[/tex]
[tex]\vec B = (4,-10)-\left(x+6,\frac{1}{3}\cdot y \right)[/tex]
[tex]\vec B = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex]
The coordinates of the other endpoint are [tex]B(x,y) = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex].

900 people attended a football game. If 25% of the people who attended were teenagers, how many teenagers attended the game?
The football game was attended by 225 teenagers out of 900 people who attended the game.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
The number of teenagers who attended the game can be calculated by finding the percentage of people who were teenagers. The word formula for the calculation as;
Number of teenagers in the game = 900 × 25%
Writing the percentage as fraction;
Number of teenagers in the game = 900 × 25/100
Cancelling zero as common in numerator and denominator
Number of teenagers in the game = 9 × 25
Performing multiplication on Right Hand Side of the equation
Number of teenagers in the game = 225
Hence, there are 225 teenagers.

Lindy is going to New England to visit her brother for spring break and wants to know what the weather will be like. Her brother is a chemist, so naturally he tells her it is expected to be 272 Kelvin while she is in town. Can you help her find the temperature in °F so she can know if she should pack a jacket or not?
Answer:
29.93° F
____________________
The value of the temperature of 272 Kelvin in Fahrenheit is 29.93° F.
How to Convert Kelvin to Fahrenheit?To convert Kelvin to Fahrenheit, enter the supplied value into the below k to f formula. The following are the procedures for converting k to f (Kelvin to Fahrenheit): °F = (K − 273.15) × 1.8 + 32.
Substitute the given value (in K) in the formula:
Then simplify the expression and find the solution.
Then write the final answer in °F.
To determine the temperature in °F when it is in 272° Kelvin
We need to substitute the value of K as 272 in the K to F formula given above.
⇒ °F = (272 − 273.15) × 1.8 + 32
⇒ °F = -1.15 × 1.8 + 32
⇒ °F = -2.07+ 32
⇒ °F = 29.93°
Therefore, the value of 272 K in Fahrenheit is 29.93° F.

Human skin has a thickness of about 5 * 10-3 meter. A
grain of sand has a thickness of about 1* 10-3 meter.
About how many grains of sand would it take to match the thickness
of human skin?
Grains of Sand
Human Skin
(1 x 10)
(5 x 10-)
Answer:
human skin is thicker than sand , hope this helps
It will take 5 grains of sand to match the thickness of a human's skin.
What is comparison?Comparing numbers in maths defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.
Given that, Human skin has a thickness of about 5×10⁻³ meter. A grain of sand has a thickness of about 1×10⁻³ meter.
As we can see the that the measurement of sand grain is greater than that of human skin's measurement, the skin is about 5×10⁻³ meter and sand grain is about 1×10⁻³ meter.
We can say,
5×10⁻³ > 1×10⁻³
The human skin's thickness is 5 times greater than the thickness of a sand grain.
Hence, we have to multiply by 5 to measure of the thickness of a sand grain to make it equal to human skin's measurement,
Hence, It will take 5 grains of sand to match the thickness of a human's skin.

How to solve x^4 -10x^2 +9
Answer:
(x² - 9)(x² - 1)
Step-by-step explanation:
Using Quadratic trinomials
Factor x⁴ - 10x² + 9
Step 1: Find the two integers whose product of 9 and whose sum of -10
Product
-9 × -1 = 9
Sum
-9 + -1 = -10
Step 2: Use -1 and -9 to complete the factors
x⁴ - 10x² + 9 = (x² - 9)(x² - 1)
Step 3: Use the foil method to check the factors
(x² - 9)(x² - 1) = x⁴ - 1x² - 9x² + 9 = x⁴ - 10x² + 9
