Step-by-step explanation:
<u>Dilations</u>
Given a point A(x,y) and a scale factor k the dilated image of A, called A' is calculated as A'=(kx,ky), assuming the same scale factor is applied in both axes.
The pentagon ABCDE was dilated to create pentagon A'B'C'D'E'. To find the dilaton rule used, we must find two clear points where the coordinates of both axes can be easily read from the graph.
Point C(-2,0) maps to C'(-5,0). This gives us the scale factor for the x-axis of -5/(-2)= 5/2.
The y-coordinate of E is 2 and the y-coordinate of E' is 5. This gives us the same scale factor for the y-axis of 5/2.
Thus, the rule to dilate the pentagon is:
B
Step-by-step explanation:
The problem bothers on fractions, here we are being presented with mixed fractions.
what we are going to do bascially is to subtract the sum of all the uloaded
peat moss in sites 1 and 2 to get from the peat moss to get the remaining for the third site
therefore
we then have to convert the mixed fraction to further simplify the problem we have
we then solve the fraction to the right of the negative symbol first
We can now convert to mixed fraction
For the third site the remainder is 5 12/25
