Answer:

q=1

Step-by-step explanation:

(I will use the cross multiplication method)

Step 1: multiply 20 x 4 (80)

Step 2: divide 80 by 40 (2)

Step 3: subtract 1 from the 2

4/1 = 40/20

If you want to check multiply 40 x 2 and 20 x 4

if they have the same answer then your answer is right.

40 x 2= 80

20 x 4=80

80=80

Answer:

q=1

Step-by-step explanation:

\frac{4}{q+1} =\frac{40}{20} \\\\\frac{4}{q+1} =\frac{4}{2} \\\\\frac{4}{q+1} =\frac{4}{2} \\\\\frac{4}{q+1} =\frac{2}{1} \\\\\frac{2}{q+1} =\frac{1}{1} \\\\q+1=2\\q=1

Encuentra la ecuacion de la parabola con vertice en el origen y foco en las cordenadas 0,1en su forma ordinaria y general
marusya05 [52]

Answer:

x^{2}=4y

y=\frac{1}{4}x^{2}

Step-by-step explanation:

Forma ordinaria

La ecuación de la parabola de manera ordinaria está dada por:

(x-h)^{2}=4p(y-k) (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:

(x-0)^{2}=4*1(y-0)

x^{2}=4y (2)

 

Forma general  

La forma general de una parábola esta dada por la siquiente ecuación

y=ax^{2}+bx+c

Reordenando la ecuación (2) tenemos:

y=\frac{1}{4}x^{2}

Espero esto te haya ayudado!
