You must consider the three couples of points, before and after the dilation.
The bottom-left point was (3,3) and it becomes (4,5). The line connecting these two points is y = 2 x - 3
The bottom-right point was (6,3) and it becomes (10,5). The line connecting these two points is y = x/2
The top point points was (5,4) and it becomes (8,7). The line connecting these two points is y = x-1.
Those three lines meet at (2,1), and thus this is the center of dilation.
The square root of 1007
written as,
√1007=
=31.733
or
31.7 rounded.
X equals 4 and the x axis
10 time as much of something is basically just multiplication, so all you have do is multiply 60x10 which equals 600 :)
Answer:
Internal validity
Step-by-step explanation:
Internal validity is a scientific study that emphasize on the fact that there is a proof to validate a specific study. Let's say i'm a forensics scientist for example; and there was a recent crime scene in some nearby sub-urban area which demands our call, when present at the scene, The main task there is to gather information as much as we can which is required to be investigate in the laboratory for further analysis.The process of information gathering is our independent variables which varies with different causes of the crime, the laboratory analysis that make deductions (which is cause by some manipulation) of the information gathered is our dependent variables.
Therefore, we can conclude that Internal validity refers to the degree to which changes in the dependent variable are due to the manipulation of the independent variable.
