For this we will use kinematic equations.
We need the time of flight to compute the range.
With the given information, the most useful formula is:
Δy=v0yt−g2t2
Because our equation is taking only vertical motion into account,
v0y=30sin(45)
Because we are looking for the range of the object,
Δy=0
This leaves us with only one unknown: t
0=30sin(45)t−g2t2
g2t2=30sin(45)t
g2t=30sin(45)
t=60gsin(45)
For horizontal distance, the formula we need is:
Δx=v0xt
Because we are taking into account the horizontal range,
v0x=30cos(45)
In substituting our derived values into the equation we can see that:
Δx=30cos(45)∗60gsin(45)
Range=30cos(45)∗60gsin(45)
Given that the manager wants to know the type of vegetarian dishes that the people prefer, the sample that is going to provide him with the most accurate data is:
- a random group of 40 people on the street
The reason for this is because this sample has the most number and the people that are used for the sampling were chosen randomly.
A random sampling is very good because it provides an opportunity for every member of a population to be selected.

By applying the containment strategy, the United States' objective was to prevent the expansion of the Soviet Union's influence in the world.
<h3 /><h3>What is the containment strategy?</h3>
It can be understood as a foreign policy strategy to prevent the spread of the communist system, being the policy that guided the Cold war, which took place between the USA and the USSR after the end of the second world war.
Therefore, the containment strategy is a foreign policy that aimed to influence the allies to prevent the strengthening of communism.
