If you follow is rule : P(x,y)>180° rotation>P'(-x,-y). the negative signs doesn't mean to make it negative but to change it to the opposite sign. If it's positive it goes to negative. And if it's negative is goes to positive. The rotated image would have the points: (1,2) (4,4) (3,7)
Answer:
Step-by-step explanation:
Forma ordinaria
La ecuación de la parabola de manera ordinaria está dada por:
(1)
Donde:
- (h,k) es la coordenda del vértice, en nuestro caso (0,0) ya que está en el origen.
- (h,k+p) es la coordenda del foco, en nuestro caso (0,1).
Por lo tanto h = 0, k = 0 y p = 1.
Remplazando estos valores en la ecuación de la parábola, tenemos:
(2)
Forma general
La forma general de una parábola esta dada por la siquiente ecuación
Reordenando la ecuación (2) tenemos:

Answer: PQ = 18
Step-by-step explanation:
You would divide 21/14 to see what the size difference in the triangles is to get 1.5. 1.5x12=18
The first blank on the left side should be 0 I think
Answer:
M is not parellel to N because they do not create supplementary angles with the lines that it passes through.
J and K are parallel to each other because they create supplementary angles with line m
supplementary angles add up to 180 and if parallel lines create supplementary angles with the line they cross then they are parallel to each other if that makes sense
105+75=180
