En cierto cultivo, inicialmente había 1000 amebas que se reproducen por biparticion cada día ¿Cuántas amebas habrá al cabo de 30 días después que se inició el cultivo ?
Answers
Answer: 1,073,741,824,000 amebas
Step-by-step explanation:
Bipartición significa que la población de amebas se duplica cada día.
Entonces si inicialmente hay 1000, después de un día van a haber:
2*1000.
Después del segundo día se vuelven a duplicar, entonces van a haber:
2*(2*1000) = (2^2)*1000
Después del tercer día, lo mismo:
2*(2^2)*1000 = (2^3)*1000.
A esta altura ya se puede ver el patrón, podemos concluir que después de N días, la población de amebas va a ser:
P(N) = (2^N)*1000.
Entonces respondiendo a la pregunta:
¿Cuántas amebas habrá al cabo de 30 días después que se inició el cultivo?
Tenemos que tomar N = 30
P(30) = (2^30)*1000 = 1,073,741,824,000 amebas

Find an expression for the nth term (tn) in each of the following sequence:
2, 6, 10, 14, 18…
Answers
Answer:
The answer is 34
Step-by-step explanation: I just have a big brain
Answer: [tex]t_n = 4n - 2[/tex]
===========================================
Work Shown:
The first term is a = 2 and the common difference is d = 4, since we're adding 4 to each term to get the next term.
[tex]t_n = \text{nth term of arithmetic sequence}\\\\t_n = a+d(n-1)\\\\t_n = 2 + 4(n-1)\\\\t_n = 2 + 4n - 4\\\\t_n = 4n - 2[/tex]
Which is the answer.
--------------------------------
If you were to plug in say n = 3, then we get
[tex]t_n = 4n - 2\\\\t_3 = 4(3) - 2\\\\t_3 = 12 - 2\\\\t_3 = 10[/tex]
showing that 10 is the third term, which matches with what the original sequence shows. I'll let you check the other values of n to fully confirm the answer.

PLEASE HELP 4. The Buff City Soaps in Arlington is counting how many soaps and bath bombs they sell in a given day. In total, they sold 33 bath products. The number of soaps they sold was one more than three times the number of bath bombs. WRITE THE SYSTEM OF EQUATIONS.

33 = x + (3x + 1)
x = bath bombs
So 3x is three times as many bath bombs, then the plus one makes it so that the soaps sold is more than three times the amount of bath bombs sold

A function f is called decreasing on an interval if f (a) > f (b) whenever a < b and a, b are in the interval.
Step-by-step explanation:
The domain of the function shown here is the interval [1, 6].On the interval [1, 3], the graph of this function gets higher from left to right; thus we say that this function is increasing on the interval [1, 3].
On the interval [3, 6], the graph of this function gets lower from left to right; thus we say that this function is decreasing on the interval [3, 6].

you can either use the graph or algebra to find the slope.
to use the graph, simply count how many spaces up/down and to the left/right that you go.
to use algebra, take the coordinates of your two points and do (y2-y1)/(x2-x1).
