Step-by-step explanation:
Given that,
Directrix, d= -5, and eccentricity, e = 2.
The polar equation of the conic is given by :
Put all the values,
As e>1, it is a hyperbola. Hence, this is the required solution.
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.
Answer:
2 and a half hours
Step-by-step explanation:
Hello!
To find this we add how far Mary and Ann travel and subtract that from the total distance till we get 0
2.5 + 2 = 4.5
11.25 - 4.5 = 6.75 First hour
6.75 - 4.5 = 2.25 Second hour
2.25 is half of 4.5 and half an hour is 30 minutes
2.25 -2.25 = 0 half hour
It will take them 2 and a half hours
The answer is 2 and a half hours
Hope this helps!
