Answer:  y = -(x + 2)²

<u>Step-by-step explanation:</u>

The vertex form of a quadratic equation is: y = a(bx - h)² + k    where

  • a: vertical stretch (if negative it is a reflection across x-axis)
  • b: horizontal stretch (if negative it is a reflection across y-axis)
  • h: horizontal shift (negative is left and positive is right)
  • k: vertical shift (negative is down and positive is up)
  • (h, k): vertex of the function

Given: reflection over x-axis → a = -1,   two units left → c = -2

Input those values into the equation:  y = -(x - (-2))²

                                              simplify:   y = -(x + 2)²

estaba previsto destinar 3/14 de partes de una finca a plazas de aparcamiento pero finalmente han destinado 3/4 de lo previsto a
JulsSmile [24]

Queremos ver que fracción de la finca se ha destinado a plazas de aparcamiento.

La solución es:

La fracción de la finca que se destina a plaas de aparcamiento es 3/56

Sabemos que originalmente se iba a destinar 3/14 del total de la finca a plazas de aparcamiento, pero finalmente se destino 3/4 de lo previsto a zonas ajardinadas.

Es decir, <u>se destino 3/4 de los 3/14 del total de la finca</u> a zonas ajardinadas, entonces <u>el 1/4 restante se dedico a plazas de aparcamiento</u>, esto da:

(1/4)*3/14  = 3/56

La fracción de la finca que se destina a plaas de aparcamiento es 3/56

Which recursive formula can be used to generate the sequence shown, where f(1) = 5 and n &gt; 1?
Degger [83]

The recursive formula a_n = a_{n-1}-6 can be used to generate the shown sequence

Step-by-step explanation:

Recursive formula is the formula that is used to generate the next term of a sequence using previous term.

The general form of arithmetic sequence's recursive formula is:

a_n = a_{n-1}+d

Given

5,-1,-7,-13,-19

Here

a_1 = 5\\a_2 = -1\\a_3 = -7

First of all we have to find the common difference of the sequence.

So,

d = a_2 -a_1 = -1-5 = -6\\d = a_3-a_2 = -7+1 = -6

Putting the value of d in the general recursive formula

a_n = a_{n-1}-6

Hence,

The recursive formula a_n = a_{n-1}-6 can be used to generate the shown sequence
