Answer:
One fourth (1/4) of anything is 25%.
100% is a whole (the committe). Divide the whole (100%) by 4 to get 25%. 1/4
So the equation to find the discriminant is 
, with a = x^2 coefficient, b = x coefficient, and c = constant. Using that formula, our equation is 
- Firstly, solve the exponent and multiplications:
- Next, do the subtraction, and your discriminant is -23.
Now because the discriminant is <u>less than zero</u>, there are <u>no real solutions.</u>
N would be the variable that we are solving for.
Lets solve:-
n * 3.25 = 325
3.25/3.25 = 325/3.25
n = 100
Answer: n = 100
Answer:
There will be 22.5 grams left after 32 hours.
Step-by-step explanation:
A half-life is how long it takes for half of the amount to go away. In this case, we see that we have two half-life periods worth, which you can determine by dividing the total time by the half-life time.
32hrs/8hrs = 4 half lives.
Now we can raise 1/2 to the power of how many half lives we have (2). Then we multiply that by the amount in the sample.
(1/2)^4 * 360
1/16 * 360
22.5 grams
And this is an exponential function.
24 times, with the exponent of 4
Hope I helped YOU! :) ;)☆
