Simplify the expression where possible. (t 9) -8
makvit [3.9K]

Answer:

\frac{1}{t^{72}}.

Step-by-step explanation:

To solve this problem, we need to simplify the expression (t^{9})^{-8}.

We know that (x^{a})^{b} = x^{ab}

Therefore:

(t^{9})^{-8} =t^{-72} =\frac{1}{t^{72}}.

If a city that currently has a population of 1000 triples in size every 8 years, what will the population be in 24 years? Is the
Brilliant_brown [7]
For this case we have a function of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: growth rate
 t: time
 Substituting values we have:
 y = 1000 * (3) ^ ((1/8) * t)
 For 24 years we have:
 y = 1000 * (3) ^ ((1/8) * 24)
 y = 27000
 Answer:
 
D) 27,000; exponential

Given a term in the geometric sequence and the common ratio find the first five terms the explicit form and the recursive formul
Pani-rosa [81]
A1 = 4
a2 = 5a1 = 5 x 4 = 20
a3 = 5a2 = 5 x 20 = 100
a4 = 5a3 = 5 x 100 = 500
a5 = 5a4 = 5 x 500 = 2,500

Tn = ar^(n-1); where a = 4, r = 5
Tn = 4(5)^(n-1) = 4/5 (5)^n
Explicit formular is Tn = 4/5 (5)^n

Recursive formular is a_{n+1} = 5a_{n-1}
