Answer:
Find the distance between (-1, 1) and (3, 4).
This problem is solved simply by plugging our x- and y-values into the distance formula:
D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−−√=
=16+9−−−−−√=25−−√=5
Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.
If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:
(x1+x22,y1+y22)
I think it would be 77p... It might not be but i think it is
<span>0.9% glucose solution means there are 0.9 g of glucose per 100 mL water.
</span><span> The concentration is required per litre for molar concentration:
0.9% glucose solution contains 9 g of glucose per 1000 mL or 1 L of water.
Molar mass of glucose is 180.16 g mol^-1 so 9 g = 9g/180.16 g mol^-1 = 0.05 moles
</span><span> 1 L of water contains 0.05 moles of glucose so molar concentration is 0.05 M or 0.05 mol/L </span>
