Step-by-step explanation:

Statement Reasons

1). Line PQ is an angle bisector of ∠MPN D). Given

2). ∠MPQ ≅ ∠NPQ A). Definition of angle bisector

3). m∠MPQ = m∠NPQ F). Definition of congruent

angles.

4). m∠MPQ + m∠NPQ = m∠MPN C). Angle addition postulate

5). m∠MPQ + m∠MPQ = m∠MPN G). Substitution property of

equality

6). 2(m∠MPQ) = m∠MPN B). Distributive property

7). m∠MPQ = $\frac{1}{2}(m\angle MPN)$ E). Division property of equality

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

Max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
