Answer:
Photograph: bird's eye view of a site; interview: personal analysis and biased; tax records: limited accessibility; biography: unreliability of human memory.
Explanation:
There are generally always some drawbacks when considering different sources of historical information and a good researcher has to take these factors into account. Photographs are limited because they give you very little context. Interviews can be limiting because you get a personal view from just one individual. Tax records are likely protected due to privacy concerns and statutes. Biography can have drawbacks as well because the person may embellish past events or overemphasize the significance or attribute meaning in ways that are not entirely truthful or objective.
Answer:
B. The Earth is tilted relative to the ecliptic
Explanation:
- Its due to the earth has an axial tilt of 23.5 degrees which is an inclined motion, relative to the orbital plane of rotation. This is the angle of obliquity of the earth from its center.
- For this reason, the earth has solstice in summer, winter, vernal and equinoxes and owning to the fact that the continents in the north have winter in the Northern hemisphere and continents in the south have summer.
- Without this tilt, the earth would have climatic extremes. Day and night time of the earth are also influenced by the same rotational motion.
I believe that the perpendicular equation would be the opposite sign and the reciprocal of the original slope. Then you just plug in the x and y coordinate to y=mx+b and solve for b.
y=4x+b
3=4(-4)+b
3=-16+b
b=19
y=4x+19
