Need Help with finding half life or doubling time

Mathematics
1 answer:
adell [148]3 years ago
8 0

Answer:

12.2 hours

Step-by-step explanation:

You want to find t such that y = 2·y₀. That is, you want to solve

... 2y₀ = y₀·e^(0.0567t)

Dividing by y₀, you have

... 2 = e^(0.0567t)

and taking the natural log gives ..

... ln(2) = 0.0567t

... ln(2)/0.0567 = t ≈ 12.2248 . . . . divide by the coefficient of t

The doubling time is approximately 12.2 hours.

Find the equation of a line that contains the points (−2,2) and (−6,−5). Write the equation in slope-intercept form, using fract
mamaluj [8]

Answer:

y = (4/7)X + 22/7

Step-by-step explanation:

Moving from (-2, 2) to (-6, -5), we see that x (the "run") decreases by 4 and y (the "rise") decreases by 7 (from 2 to -5).  Thus, the slope is m = rise / run =

-4/(- 7) = 4/7.  The slope intercept form y = mx + b takes on the specific values 4/7 for m, 2 for y and -2 for x:

2 = 4/7(-2) + b, or 14 = -8 + 7b.  Thus, 22 = 7b, and b = 22/7.

The desired equation is y = (4/7)X + 22/7.
