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.
The Black Sea and Aegean Sea (Hopefully this is correct!)
The correct answer is D) They cultivated the “three sisters” crops of corn, beans, and squash.
The two agricultural contributions that are common to both Northeast Woodland Indians and Southeast Indians are the following: they cultivated the “three sisters” crops of corn, beans, and squash.
The term "three sisters" in agriculture refers to the most important crops in the agriculture fields of some Native American tribes such as the Northeast Woodland Indians and Southeast Indians. The crops were corn, beans, and squash. The Native American Indians used a special agriculture technique called companion planting, that was the planting of different crops close to each other. So squash, corn, and beans were planted in proximity to each other.
In the late 1800s, most Americans accepted laissez faire economics in theory. In practice, however, many supported government involvement when it benefited them.
