Answer:

2^5

Step-by-step explanation:

Properties of exponents:

Quotient of power ( when the bases are different and the exponents are the same : \frac{a^m}{b^m} =(\frac{a}{b} )^2 )

Explanation of property. When exponents are being divided, if the exponents are the same but the bases are different then divide the bases and keep the exponents the same

We want to find \frac{10^5}{5^5}

Because they have the same exponent but different bases we can use the property stated earlier where you divide the bases and keep the exponent the same.

The bases are 10 and 5. 10 is being divided by 5 so we do 10/5 which equals 2. The property says to keep the exponent the same so the answer is 2^5

Steps in multiplying fractions. Remember: finding common denominator is not necessary in multiplying fractions. 
Common denominators are only needed in adding and subtracting fractions.

14/15 * 5/2 

Step 1. Multiply the numerators.
14 * 5 = 70
Step 2. Multiply the denominators
15 * 2 = 30
Step 3. Simplify the fraction.
70/30 = 2 10/30 = 2 1/3      

*the fraction 10/30 can still be simplified by dividing both numbers by 10. Hence, 1/3.

Steps in Dividing fractions.

24/60 ÷ 8/15

Step 1. Get the reciprocal of the 2nd fraction. Reciprocal means the reverse of the fraction. Simply swap the places of the numbers.

Reciprocal of 8/15 is 15/8.

Step 2. Multiply the 1st fraction to the reciprocal of the 2nd fraction. Follow steps in multiplying fractions.

24/60 * 15/8 = (24*15) / (60*8) = 360/480

Step 3. Simplify the fraction.
360/480 = 9 / 12 = 3/4

360 ÷ 40 =   9 ;   9 ÷ 3 = 3
480 ÷ 40 = 12 ; 12 ÷ 3 = 4

qaws [65]

Answer: D) f(n)=8(1.5)^{n-1}


Step-by-step explanation:

From the given table we can see that this is not representing a linear function as the rate of change is not constant.

So it can be exponential growth function A(b)^{n-1},  where A is the initial amount , b is the multiplicative rate of growth and n is the time period in weeks.

Now here at n=1 , f(n)=8

Therefore, A=8

Now, for n=2

f(2)=8(b)^{2-1}\\\Rightarrow12=8b\\\Rightarrow\ b=\frac{12}{8}\\\Rightarrow\ b=1.5

By substitute the values of A and b in the above equation, we get the equation f(n)=8(1.5)^{n-1}

Therefore, the function best shows the relationship between n and f(n) is

f(n)=8(1.5)^{n-1}, where n is the number of weeks.
