If the negative square root is found to be one of your solutions, then that is indicative of a pair of imaginary roots (the imaginary i). According to the conjugate rule, if you have one solution that is imaginary, you will have another but with the opposite sign. For example, if a solution to a quadratic is found to be 2 - i, then its conjugate, 2 + i is also a solution. They will ALWAYS go in pairs. Same thing with radical solutions. If one solution is found to be 
then 
will also be a solution.
Answer:
810 mL of hardener
Step-by-step explanation:
You need 45 mL of hardener for each container and you have 18 containers so:
45 x 18 = 810 mL
From stock A
The price increases as time passes till they both became constant eventually the price decreases as time passes
From stock B
The price is low in the beginning however as time passes it increases till it became constant
The answer is 1:2. all you have to do is add the dots for example 4/5 would be 4:5
For this case we have the following equation:
s = 300 / d
Where,
s: the speed of the current in a certain whirlpool
d: the distance from the center of the whirlpool
We have then that:
If the distance from the center of the whirpool is large, the speed is small.
If the distance from the center of the whirlpool is very small, the speed tends to infinity
Answer:
Large distance, small speed.
Short distance, speed tends to infinity.
