QUESTION 1-  

QUESTION 2-  

QUESTION3-

Step-by-step explanation:

For Question 1

From the given point(-3,4), we can deduce the following.

The point is in the 2nd quadrant.

The right-angled triangle which is formed has a hypotenuse of length 5 by Pythagoras theorem whrere B=3 and P=4.

The third quadrant are from 90° to 180° in which the angle lie.

so  

For Question 2

From the given point(-4,-5), we can deduce the following.

The point is in the 3rd quadrant.

The right-angled triangle which is formed has a hypotenuse of length   by Pythagoras theorem whrere B=-4 and P=-5.

The third quadrant are from 180° to 270° in which the angle lie.

so  

For Question 3

The line with equation 4b + a = 0 , we can deduce that the value of

slope of line  

Hypotenuse of length by Pythagoras theorem whrere B=4and P=1.

so  .

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

la fórmula de la directriz

es x + p = 0

resolviendo:

y^2-9x = 0

y^2 = 9x

4p = 9, entonces p = 9/4

entonces el foco tendrá la

coordenada f(9/4,0)

la directriz vendrá

expresada por

x + p = 0

x = -p

x = -9/4

el problema indica que la

ordenada es igual a 6, entonces

(6)^2=9x

x = 36/9

x = 4

entonces el punto al cual

hay que obtener la distancia será p(4,6)

calculando se tendrá: pf = 

pf = 6,25 u
