Look, Dav...
This is a simple ex of Pyth. Theorem
26^2=24^2 + (DB)^2
then: DB = 10
Answer:
b = 8/3 or b = -9/5
Step-by-step explanation:
Solve for b over the real numbers:
(5 b + 9) (8 - 3 b) = 0
Split into two equations:
8 - 3 b = 0 or 5 b + 9 = 0
Multiply both sides by -1:
3 b - 8 = 0 or 5 b + 9 = 0
Add 8 to both sides:
3 b = 8 or 5 b + 9 = 0
Divide both sides by 3:
b = 8/3 or 5 b + 9 = 0
Subtract 9 from both sides:
b = 8/3 or 5 b = -9
Divide both sides by 5:
Answer: b = 8/3 or b = -9/5
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.
