For this case we have the following expression:
We must find the common factor of the coefficients.
We have then:
- <em>Using common factor 3:
</em>
- <em>Using common factor 9:
</em>
Answer:
The two equivalent expressions are given by:
Answer:
a_n = 2^(n - 1) 3^(3 - n)
Step-by-step explanation:
9,6,4,8/3,…
a1 = 3^2
a2 = 3 * 2
a3 = 2^2
As we can see, the 3 ^x is decreasing and the 2^ y is increasing
We need to play with the exponent in terms of n
Lets look at the exponent for the base of 2
a1 = 3^2 2^0
a2 = 3^1 2^1
a3 = 3^ 0 2^2
an = 3^ 2^(n-1)
I picked n-1 because that is where it starts 0
n = 1 (1-1) =0
n=2 (2-1) =1
n=3 (3-1) =2
Now we need to figure out the exponent for the 3 base
I will pick (3-n)
n =1 (3-1) =2
n =2 (3-2) =1
n=3 (3-3) =0
Answer:
245 pounds in 7 days
Step-by-step explanation:
35 pounds= 1 day for one person
35*7=245
-1/3=-3-/9
-4/9-3/9=-7/9
z-7/9=5/9
7/9+5/9=12/9
z=1 1/3
