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].

The football game was attended by 225 teenagers out of 900 people who attended the game.

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.

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

Answer:

29.93° F

____________________

The value of the temperature of 272 Kelvin in Fahrenheit is 29.93° F.

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.

Answer:

Step-by-step explanation:

(2x - 6) + 4(x - 3)         use the distributive property a(b + c) = ab + ac

= 2x - 6 + (4)(x) + (4)(-3)

= 2x - 6 + 4x - 12        combine like terms

= (2x + 4x) + (-6 - 12)

= 6x - 18

m<A=76

m<BCD=105

Step-by-step explanation:

in a triangle, all of the angles add up to 180. so m<a=76 degrees

BCA and BCD are supplementary angles which means they add up to 180, so m<BCD=105 degrees

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.

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.

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite the 90° angle.

The trigonometric reciprocal of sine, cosine, and tangent are cosecant, secant, and cotangent, respectively. Therefore, the option that is not an example of trigonometric reciprocals of sine, cosine, and tangent is theorem.
