A gear in a machine turns 2 1/2 times every hour.

We can solve this by multiplying those two numbers but we place them in improper fraction.

2 1/2 x 2 1/4
becomes
5/2 x 9/4

for fraction multiplication, just multiply numerator by numerator and denominator by denominator

5/2 x 9/4 = 45/8

we can simplify this into mixed fraction while numbers in whole numbers and remainder in numerator

5 5/8 is the answer

Write each sequence as a function.
Fiesta28 [93]

Answer: f(n)=3^{n-1}

Step-by-step explanation:

Given Recursive formula : a_{n+1} = 3a_n,, a_1=1

Then,  a_2=a_{1+1} = 3a_1=3(1)=3

a_3=a_{2+1} = 3a_2=3(3)=9

a_4=a_{3+1} = 3a_3=3(9)=27

We can write it as : f(n)=3^{n-1}

such that

n      f(n)=3^{n-1}

1       f(1)=3^{1-1}=1

2       f(2)=3^{2-1}=3^1=3

3       f(3)=3^{3-1}=3^2=9

Hence, the required function: f(n)=3^{n-1}

The third one, 2 to the power of 5 over 6

√2  * 3√2

convert from radical form to exponent form to solve for the same root
( x^m/n = n√x^m )

2^(1/2) * 2^(1/3)  
2^{3/6} * 2^{2/6} - find common denominator (6)
6√(2^3) * 6√(2^2)  - convert back to radical form 
6√(2^3 * 2^2)- combine

6<span>√(</span>2^5)
then convert to exponential form again
