Eli had $10, but he lost some of it. His mom doubled the money he had left. Eli wrote the expression 2(10 – k) to show how much

Juli2301 [7.4K]

Answer:

Equation 1

In the story it said Eli's mom doubled the money he left, that is what the two represents. 10 is the original amount he had. -k is the money he lost.

Equation 2

20 is the the result of the original 10 being multiplied. -2k, now the 2 is still the amount that the mom doubled his amount by, and the k is how much money Eli lost.

Hope this helps!!

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!

The square of a number x is 92. The number x is between what two consecutive whole numbers?

natta225 [31]

The number X is placed somewhere between 9 and 10. That's because 9 squared is 81 and 10 squared is 100.

A) There are 100 students who play at least one of volleyball, soccer and hockey, of these 50 play au three games, 84 play socce

Scilla [17]

Answer:

<h2>i) 3</h2><h2>ii) 5</h2>

Step-by-step explanation:

Let H be the set of students who play Hokey

V be the set of students who play Volleyball

S be the set of students who play Soccer

======================================

card(volleyball only) = card(V) - [card(V∩H∩S) + card(V∩H only) + card(V∩S only)]

= 73 - [50 + (58-50) + (62-50)]

= 73 - [50 + 8 + 12]

= 73 - 70

= 3

………………………………………………

Card(Hokey only) = 100 - [3 + 8 + 50 + 10 + 12 + 12]

= 100 - 95

= 5

…………………

<u><em>Note</em></u> :

A Venn diagram might be helpful in such case.
