Answer:
My Take on this
The height of the wall can be related with the Horizontal distance traveled by the equation of the trajectory
y=xtan∆ - gx²(1+tan²∆)/(2u²)
The wall is at distance x1
So thats the horizontal distance we'll use... We need to find its corresponding vertical distance "y"
So
Applying the formula
∆=45°
x=x1
g=9.8ms-²
u=velocity of projection
Substituting
y= x1tan45 - 9.8x1²[1+(tan²45)]/2u²
tan45°=1
y= x1 -4.9x²(1 +1)/u
y= x1 - 4.9x²•2/u²
y= x1 - 9.8x²/u².

Andrew Carnegie: Steel Magnate
Over the next few decades, he created a steel empire, maximizing profits and minimizing inefficiencies through ownership of factories, raw materials and transportation infrastructure involved in steel making. In 1892, his primary holdings were consolidated to form Carnegie Steel Company.
Explanation:
Interest groups are the group of people who attempt to influence public policy, it is also known as a pressure group, special interests groups, and lobbyests.
The purpose of interest groups is to shape public policy, bring awareness, represents shared attitudes instead of geography and provide information of the government. In the Mid 1800's interest group describe as anti-slavery, fraternals, and religions, in the late 1800s it describes business associations
