Answer:
0.19g/mL
Step-by-step explanation:
The concentration of a solution is how much of a substance in in another substance, usually the amount of solute in a solvent.
The solute is the active ingredient powder. The solvent is the NS solution.
Divide the solute by the solvent.
75g ÷ 400mL
= 75g/400mL Simplify for solute per one unit, 1 mL. Divide top by bottom.
= 0.1875g/mL Round to the nearest hundredth, second decimal place.
≈ 0.19g/mL
Therefore the final concentration is 0.19g/mL.
Statement A: The line is on a different plane from the points.
Answer:
To find the length you divide the area by the width
Step-by-step explanation:
4 1/2 divided by 2 1/2 = 9/2 divided by 5/2 (i converted them to improper fractions) 9/2 divided by 5/2 equals 9/2 x 2/5 (because you have to use the reciprocal) 9/2 x 2/5 = 18/10 which equals 1 8/10 which equals 1 4/5 (i simplified)
So you answer is 1 4/5 which is the length (Please mark brainliest)
Denote the circle of radius by . is simple and closed, so by Green's theorem the line integral reduces to a double integral over the interior of (call it ):
is a circle of radius , so we can write the double integral in polar coordinates as
a. For , we have
b. Let denote the integral with unknown parameter ,
By the fundamental theorem of calculus,
has critical points when
If , then line integral is 0, so we ignore that critical point. For the other two, we would find .
