Answer:
A
Step-by-step explanation:
Since F(x) is opening downwards the x component must be multiplied by a - number. The number in the parentheses represents horizontal movement, but it must be remember that if negative it moves right and if positive it moves left. The number outside the parentheses represents represents vertical movement and is more intuitive, where positive is up and negative is down. Keeping this in mind it should be A
We can use the distance formula to find the distance between these points.
Distance formula: 
√(-5 - 6)² + (-3 - (-3))²
√121 = 11
The difference between the points is 11.

Answer:
Controlled Experiment
Step-by-step explanation:
The controlled experiment involves the experiment in which all factors are considered as constants whereas one factor is not fixed and that one is independent variable whose effect is to be tested. In short, in controlled experiment one group of data contains control group and one or more other groups are examined by considering all other factors constant except for one factor. The control group is the group that doesn't receive any treatment whereas treatment is applied to experimental group and then effect of treatment is measured through comparing both groups.
Here group of boys is divided in to two groups
The group watched violent cartoon= Experimental group
The group watched cartoons without violence= Control group
The researchers want to know whether the violent actions of boys are linked to violent cartoon and for this purpose these boys are divided into experimental group and control group and after 1 hour of cartoons watching the researcher will observed boys for next two hours.
Hence the study is Controlled experiment.
