Can someone help me with number 15

Mathematics
1 answer:
Shalnov [3]2 years ago
4 0

Answer:

Step-by-step explanation:

We will evaluate that with n values starting at 1 and ending at 5.  To do that, simply replace the exponent n with 1, then 2, then 3, then 4, then 5.

f(1)=(\frac{2}{3})^1  so

f(1)=\frac{2}{3}

Then f(2):

f(2)=(\frac{2}{3})^2 simplifies a bit so maybe it's easier to see how to handle this:

f(2)=(\frac{2^2}{3^2}) so

f(2)=\frac{4}{9}

Then f(3):

f(3)=(\frac{2^3}{3^3})=\frac{8}{27}

And f(4):

f(4)=(\frac{2^4}{3^4})=\frac{16}{81}

And finally, f(5):

f(5)=(\frac{2^5}{3^5})=\frac{32}{243}

Which will equation show correctly we write an expression that represents the cost for a pair of shoes that is marked down 20% o
alukav5142 [94]

Answer:

A

Step-by-step explanation:

You can write an expression to represent the total cost of a pair of shoes. The price of the shoes is the variable r. The shoes are marked down 20% or 0.2r. So the new price of the shoes will be r - 0.2r. You will also have to pay a tax of 5% or 0.05 of the new price. This is written as 1.05(r - 0.2r). You can simplify it by doing whats in the parenthesis.

1.05(r - 0.2r) = 1.05r(0.8r) = 0.84r
