Step-by-step explanation:
¿Entre que números naturales consecutivos se encuentra cada raíz?
Bueno en este caso debes empezar por el 1 en adelante, pero solo sucede en números impares consecutivos. Solamente debes sumar 1,3,5,7,9,11,13,15,17,19 ..... en adelante, y en cada suma de cada sucesión encontraras un cuadrado. Ojo solo sumando en orden, tampoco sumarás 3+9, ya que te dará 12 y 12 No tiene raíz.
1+3=4,√4=2
4+5=9, √9=3
9+7=16, √16=4
16+9=25, √25=5
25+11=36, √36=6
36+13=49, √49=7
49+15=64, √64=8
64+17=81, √81=9
81+19=100, √100=10

A SI CONSECUTIVAMENTE SIEMPRE OBTENDRÁS CADA RAÍZ
¿Entre que números naturales consecutivos se encuentra cada raíz?
R= En los número impares consecutivos, comenzando por el 1 en adelante.
Answer:
54.16%
Step-by-step explanation:
The percentage of books that are some is 54.16 %
In order to find that answer you would have to calculate the total number of small books (26) over the total number of all of the books (48).
The equation would be 26/48=0.5416 however Multiply that answer by 100 and you would get 54.16% and if you want to round to the nearest whole number it would just be 54%
Answer:
9,942 bacteria were there at 10 hours.
Step-by-step explanation:
Equation for population decay:
The equation for population decay, after t hours, is given by:
In which P(0) is the initial population and r is the decay rate, as a decimal.
Researchers recorded that a certain bacteria population declined from 200,000 to 900 in 18 hours.
This means that 
and that when 
. So we use this to find r.
![\sqrt[18]{(1-r)^{18}} = \sqrt[18]{\frac{900}{200000}}](https://tex.z-dn.net/?f=%5Csqrt%5B18%5D%7B%281-r%29%5E%7B18%7D%7D%20%3D%20%5Csqrt%5B18%5D%7B%5Cfrac%7B900%7D%7B200000%7D%7D)
So
At this rate of decay, how many bacteria was there at 10 hours?
This is P(10). So
Rounding to the nearest whole number:
9,942 bacteria were there at 10 hours.
