Going off of 11% vs 1/10 Blanca received the greater percentage because 1/10 as a percent is 10%. Hope this helps.

Marizza181 [45]

Given:

$\text{ Dimension = 3}\times5$

Sol:

Area of picture is:

$\begin{gathered} =\text{ length}\times\text{ Width} \\ \\ =15 \end{gathered}$

If the cost $10 per square inch then price of 15 square inch is:

$\begin{gathered} =15\times10 \\ \\ =150 \end{gathered}$

If the quadruple of dimension that mean:

$\begin{gathered} \text{ l ength = 4 length} \\ \\ Width\text{ = 4 width} \end{gathered}$

So area is:

$\begin{gathered} A=4\text{ length}\times4\text{ Width} \\ \\ A=4(15) \\ \\ A=60 \end{gathered}$

So price is:

$\begin{gathered} =60\times10 \\ \\ =600 \end{gathered}$

What is the value of Cos n 2π=???

faust18 [17]

If n is an integer, then cos(n(2π))=1.

Take n=0, cos(2π)=cos(0)=1, n=1, cos(2π)=1, n=2, cos(2(2π))=cos(4π)=cos(0)=1...

If n is not an integer, well, ..... we don't know the value, which depends on the value of n.
