To determine the scale factor that should be used in order to correct the size of the post card, we simply have to divide the original length of the picture which is 4.5 inches by the space available, 1.8 inches. This gives an answer of,
                           scale factor = 4.5 inches / 1.8 inches = 2.5

Answer:

0.4

Step-by-step explanation:

The scale factor is the ratio of the lenght of a figure compared to the lenght of another figure and it can be used to enlarge or reduce a shape. In this case, as the customer wants to reduce the picture, to calculate the scale factor you have to divide the small length by the big length.

Scale Factor Reduction= Small length /Big length= 1.8/4.5= 0.4

The scale factor is 0.4.

Hello,

Reminders:
$\sum_{i=1}^{n} i= \dfrac{n(n+1)}{2}$



$ \sum_{i=1}^{n} i^2= \dfrac{n(n+1)}{2}$


$ \sum_{i=1}^{n} i^3= \dfrac{n^2(n+1)^2}{4} $


n=6\\
x_{0}=0\\
x_{n}=3\\
\Delta= \dfrac{x_n-x_0}{n}=0.5\\


x_{i} =0+\Delta*i= \frac{i}{2}

$ \sum_{i=1}^{n}\ \Delta*f(x_{i})=\sum_{i=1}^{6}\  \dfrac{i^3/8-6i}{2} $
$= \dfrac{1}{2}\sum_{i=1}^{6}  (\frac{i^3}{8} -6i)=\dfrac{1}{16}*\frac{(6*7)^2}{4}- \frac{9*7}{2}= -3.9575
