Answer:
S(-3, -1)
P(4, 0)
a = (Py - Sy) / (Px - Sx)^2
a = (0 - (-1)) / (4 - (-3))^2
a = 1 / 7^2
<u>a = 1 / 49</u>
Answer:
44.7 mg
Step-by-step explanation:
The equation for exponential decay can be written in the form ...
y = a·b^(t/p)
where 'a' is the initial value, 'b' is the decay factor, 'p' is the period over which the decay factor is applicable, and t is time in the same units as p.
<h3>Setup</h3>
Using the above equation, we have ...
a = initial value = 110 mg
b = decay factor = 55/110 = 1/2 over time period p=20 hours
Then the equation is ...
y = 110·(1/2)^(t/20) . . . . amount remaining after t hours
<h3>Solution</h3>
We want the amount remaining after 26 hours. That will be ...
y = 110·(1/2)^(26/20) ≈ 44.67
About 44.7 milligrams will remain after 26 hours.

I hope this helps, good luck! :)</span>
K, remember
(ab)/(cd)=(a/c)(b/d) or whatever
also
and
and
![x^ \frac{m}{n}= \sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7Bm%7D%7Bn%7D%3D%20%5Csqrt%5Bn%5D%7Bx%5Em%7D%20%20)

and
(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)
