Answer:

20 pints per hour

Step-by-step explanation:

60/6 = 10

10 x 4 = 40

40 pints/hour in the morning

60/3 = 20

20 x 1 =20

20 pints/hour in the afternoon

40 - 20 = 20

20 pint/hour difference

Sea un cuadrado de 2 pulgadas de lado uniendo los puntos medios se obtiene otro cuadrado inscrito en el anterior si repetimos es
Ne4ueva [31]

Answer:

1) La serie geométrica formada es

4, 2, 1,..., ∞

2) La suma al infinito de las áreas de los cuadrados es 8 in.²

Step-by-step explanation:

1) El área del primer cuadrado, a₁ = 2² = 4 pulgadas²

El área del siguiente cuadrado, a₂ = (√ (1² + 1²)) ² = (√2) ² = 2 pulg²

El área del siguiente cuadrado, a₃ = ((√ (2) / 2) ² + (√ (2) / 2) ²) = 1 pulg²

Por lo tanto, la razón común, r = a₂ / a₁ = 2/4 = a₃ / a₂ = 1/2

Las áreas de los cuadrados progresivos forman una progresión geométrica como sigue;

4, 4×(1/2), 4 ×(1/2)²,...,4×(1/2)^{\infty}

De donde obtenemos la serie geométrica formada de la siguiente manera;

4, 2, 1,..., ∞

2) La suma de 'n' términos de una progresión geométrica hasta el infinito para -1 <r <1 se da como sigue;

S_{\infty} = \dfrac{a}{1 - r}

Por lo tanto, la suma de las áreas de los cuadrados hasta el infinito se obtiene sustituyendo los valores de 'a' y 'r' en la ecuación anterior de la siguiente manera;

La \ suma \ al \ infinito \ del \ cuadrado \ S_{\infty}  = \dfrac{4 \ in.^2}{1 - \dfrac{1}{2} } = \dfrac{4 \ in.^2}{\left(\dfrac{1}{2} \right)} = 2 \times 4 \ in.^2= 8 \ in.^2

La suma al infinito de las áreas de los cuadrados, S_{\infty} = 8 in.²

PLEASE HURRY WILL GIVE BRAINLIEST <br> What is the solution of
ANTONII [103]

Answer:

  • Option A

Step-by-step explanation:

<u>Find zeros first:</u>

  • x² + x - 6 = x² + 3x - 2x - 6 = x(x + 3) - 2(x + 3) = (x - 2)(x + 3)
  • x = 2, x = -3, x = 7 (but x ≠ 7 as no division by zero)

<u>We have 4 intervals:</u>

  • x ≤ - 3, three negatives, the result is negative or zero
  • -3 ≤ x ≤ 2, two negatives and one positive, the result is positive or zero
  • 2 ≤ x < 7, two positives and one negative, the result is negative or zero
  • x > 7, three positives, the result is positive or zero

<u>The solution is:</u>

  • x ≤ - 3 or 2 ≤ x < 7

Correct choice is A
