Put the other line in point slope form...(solve for y :D )
3y=15x+9
y=5x+3, so this line has a slope of 5
For a line to be perpendicular to another the slopes have to be negative reciprocals of each other...mathematically...
s1*s2=-1
So for the other line to be perpendicular to the first:
5m=-1, m=-1/5, thus our other line (so far) is:
y=b-x/5, now we can use the point (-8,-1) to solve for the y-intercept, "b":
-1=b-(-8)/5
-1=b+8/5
-1=b+1.6
b=-2.6
So the perpendicular line that contains the point (-8,-1) is:
y=-0.2x-2.6
Answer:
The answer s below
Step-by-step explanation:
a) The element is going to stay as a liquid if its temperature (t) is within the range: melting point ≤ t < boiling point.
Therefore the inequality for each element is given as:
For Gold:
1064 ≤ t < 2856
For Copper:
1085 ≤ t < 2562
For Iron:
1538 ≤ t < 2861
For lead:
327 ≤ t < 1749
and for Aluminium:
660 ≤ t < 2519
b) To get the element that would be liquid for the longest time, we need to calculate the difference between the melting and boiling points (i.e boiling point - melting point).
For Gold:
Difference = 2856 - 1064 = 1792°
For Copper:
Difference = 2562 - 1064 = 1498°
For Iron:
Difference = 2861 - 1538 = 1323°
For lead:
Difference = 1749 - 327 = 1422°
and for Aluminium:
Difference = 2519 - 660 = 1859°
Since Aluminium has the largest difference between the melting and boiling points, hence it will remain liquid for the longest amount of time.
c) The element with the smallest difference between the melting and boiling points would reach the boiling point first. Therefore iron with a difference of 1323° would reach its boiling point first.
