Answer:

-1/2

Step-by-step explanation:

I''m guessing the first coordinate is supposed to be (-9,-5) instead of -(9,-5).

Slope is calculated by \frac{y2-y1}{x2-x1}

I'll use (-9,-5) as the first coordinate and (-1,-9) as the second.

Fill in the numbers and you get: \frac{(-9) - (-5)}{(-1)-(-9)}

Simplify the double negatives: \frac{-9+5}{-1+9}

Simplify again:\frac{-4}{8}

Simplify one last time (divide both sides by 4): \frac{-1}{2} (aka -\frac{1}{2})

In right triangle ABC,
Nata [24]

Answer:

A=45°

Step-by-step explanation:

soln:

given,

ABC is a right angled triangle where C is right angle

i.e. C=90°

sin A= sin B=x(let)

A=?

we know,

A+B+C=180°[°•°sum of angles of a triangle]

or, x+x+90°=180°

or,2x=90°

•°•x=45°

hence,A=45°

Lugar geométrico infinito formado por un conjunto de puntos que conservan la misma dirección
lapo4ka [179]

Answer:

l lugar geométrico de los puntos que equidistan a otros dos puntos fijos {\displaystyle A}A y {\displaystyle B}B es una recta o eje de simetría de dichos dos puntos. Si los dos puntos son los dos extremos de un segmento {\displaystyle {\overline {AB}}}\overline {AB}, dicha recta, o lugar geométrico, es llamada mediatriz y es la recta que interseca perpendicularmente a {\displaystyle {\overline {AB}}}\overline {AB} en su punto medio.

La bisectriz cumple la propiedad de que todos sus puntos equidistan a los lados de dicho ángulo, convirtiéndose la bisectriz en un caso particular del lugar geométrico que sigue a continuación.

El caso de equidistancia a dos rectas paralelas, obtenemos que la paralela media es el lugar geométrico de los puntos que las equidistan. Se observa que, bajo el punto de vista de que las rectas paralelas se cortan en el infinito -se elimina, pues, la noción de paralelismo-, pasa a ser un sinónimo de la bisectriz, donde el ángulo ha tomado valor nulo.

Secciones cónicas

Las secciones cónicas pueden ser descritas mediante sus lugares de geométria:

La circunferencia es el lugar geométrico de los puntos cuya distancia a un punto determinado, el centro, es un valor dado (el radio).

La elipse es el lugar geométrico de los puntos tales que la suma de su distancia a dos puntos fijos, los focos, es una constante equivalente a la longitud del eje mayor de la elipse.

La parábola es el lugar geométrico de los puntos cuya distancia a un foco equivale a su distancia a una recta llamada directriz.

La hipérbola es el lugar geométrico de los puntos tales que el valor absoluto de la diferencia entre sus distancias a dos puntos fijos, los focos, es igual a una constante (positiva), que equivale a la distancia entre los vértices.

Find the factorization of 180
zheka24 [161]

Answer:

180=2^2×3^2×5

Step-by-step explanation:

We have to obtain the factors of 180 which are prime numbers

A prime number being a number with only 2 factors.That is 1 and the number itself.

For example 5 only has 2 factors 1 and 5⇒5=1×5

Here are the first few prime numbers

2,3,5,7,11,13,.....

A number which is not prime is a composite number. Composite numbers have more than 2 factors. All composite numbers can be expressed as a product of prime factors.

Solve the equation below. SHOW UR WORK<br><br> 10x − 6 = 24
Lina20 [59]

Answer:

3

Step-by-step explanation:

10x-6=24

10x = 24+6 (You switch sides because you can add 24 and 6. You cannot add 10x to 24 or 6)

10x= 30

x= 30/10

x= 3

The answer is 3.
