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.

During the golden age of the Islamic empire, many advancements were made in lots of different areas. New forms of art were created, and new ways of thinking, including the beginnings of the mathematic system of algebra, emerged as well.
The scientific method <em>revolutionized the study of human society</em> during the Gilded Age and onward; sparking curiosity within the members of society, and encouraged people to <em>gain knowledge</em>, discover and investigate; causing them to question old credence, and starting to prove them wrong, thus <em>leading to technological advances</em>, and large scale production methods, the inception of intellectual movements and favored <em>drastic reforms in education</em>, thus bringing opportunities to other scope of the population, because racial, ethnic, religious, gender and socioeconomic inequalities still abounded, so it also inspired some reformers to address those inequities in some form.
Answer:
Most enslaved people lived on plantations, forced labor camps dedicated to the large-scale production of cash crops. By 1850, more than half of enslaved people in the United States grew cotton for export to northern and British textile mills.
