neonofarm [45]2 years ago

Step-by-step explanation:

I'm going to assume you meant to write \sqrt{r+1} in the equation as +1 - 1 wouldn't make much sense since they would just cancel out.

a. f(-1) = \sqrt{-1 + 1} - 1\\ f(-1) = \sqrt{0}  - 1\\f(-1) = 0-1\\f(-1) = -1

b. f(24) = \sqrt{24 + 1} - 1\\ f(24) = \sqrt{25} - 1\\f(24) = 5 - 1\\f(24) = 4

c. f(x-1) = \sqrt{(x-1)+1} -1\\f(x-1) = \sqrt{x} - 1

Answer:

6. Miles  {}     cientos       decenas      unidades

  4   {}              9                5               6

7. Catalina podrá hacer un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹

Step-by-step explanation:

6. Los valores posicionales de dígitos son;

Miles  {}     cientos       decenas      unidades

4   {}              9                5                   6

 

7. El número de cuadrados que tiene Fernando = 12

El número de cuadrados que tiene Catalina = 16

El largo y el ancho de un cuadrado son iguales, por lo tanto tenemos;

largo × ancho = Área del cuadrado

largo = ancho = lado del cuadrado

Lado del cuadrado × Lado del cuadrado = Área del cuadrado

(Lado del cuadrado) ² = Área del cuadrado

Lado del cuadrado = √ (Área del cuadrado)

Para Fernando, Área del cuadrado = 12

Lado del cuadrado para Fernando = √12 = 2 · √3 cartones

Para Catalina, Área del cuadrado = 16

Lado del cuadrado para Catalina = √16 = 4 cartones

Por tanto, Catalina podrá realizar un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹

shusha [124]

To find the midpoint, Add the two X coordinates together then divde by two and then to the same with the Y coordinates:


X = -4 + 2 = -2 / 2 = -1


Y = 6+7 = 13/2


Midpoint = (-1,13/2)
