Answer:

Ver explicacion

Step-by-step explanation:

La frecuencia de una onda se define como el número de ciclos completos que realiza una partícula en un segundo.

f = n / t = 15 ciclos / 3 segundos = 5 ciclos por segundo o Hertz

El período de una onda es el tiempo que tarda la onda en realizar una oscilación o ciclo completo.

T = t / n = 3/15 = 0,2 segundos

julia-pushkina [17]

Answer:

a. Geometric

b. 20, 10 and 5

c. Tn = 20(0.5)^n-1

d. 0.00004 ft

Step-by-step explanation:

a. The sequence is geometric

The reason for this is that we will be multiplying each term by a particular value

If it was arithmetic, we would have been adding instead. But since it is geometric, we shall multiply terms by a particular number

b. 1st term is

20

second term

1/2 * 20 = 10

Third term

1/2 * 10 = 5

c. Explicit formula

Mathematically, that will be;

Tn = ar^n-1

Where r is 1/2 or 0.5

Tn = a(0.5)^n-1

where Tn is the present term and n is the present number of the term

d. 20th term

T20 = 20 * 0.5^19

T20 = 0.00004 ft

Answer:

$1806.06 million

Step-by-step explanation:

-This is a question of proportionality.

We are given that 13.2% is equivalent to $238.4 million in chocolate expenses

-To find the total value of chocolate expenditurerealized, we divide $238.4 million by 13.2%:

Total\  sales=\frac{238.4}{0.132}\\\\=\$1806.06\ million

Hence, the total amount spent on chocolate is $1806.06 million

Mrs. Galicia is creating a bunny farm. The farm starts with 820 bunnies and is growing at a rate of 20.75% per month. How many m
drek231 [11]

The number of months it would take the bunny farm to triple in size is 5.3 months.

<h3>When would the bunny farm be triple its size?</h3>

The formula that can be used to determine the number of months it would take Mrs. Galicia's bunnies to triple in size is:

Number of years =  (In FV / PV) / r

  • FV = future population of the bunnies
  • PV = present population of the bunnies
  • r = rate of growth
  • FV / PV = 3

IN(3) / 0.2075 = 5.3 months
