A.) P(t) = P0exp(kt)
P(20/60) = 40 exp(20k/60)
80 = 40 exp(k/3)
exp(k/3) = 80/40 = 2
k/3 = ln(2)
k = 3ln(2)

b.) P(8) = 40(2)^24 = 40(16777216) = 671088640 cells

d.) Rate of change = exp(8k) = exp(8(3ln(2)) = exp(24ln(2)) = exp(16.6355) = 16777216 cells / hour

e.) P(t) = 40(2)^3t; t in hours
1,000,000 = 40(8)^t
25,000 = 8^t
ln(25,000) = t ln(8)
t = ln(25,000)/ln(8) = 4.87 hours

How do you solve -5m+9n= 15, for m

Fed [463]

Answer:

m= 9/5 n - 3

Step-by-step explanation:

Let's solve for m.

−5m+9n=15

Step 1: Add -9n to both sides.

−5m+9n+−9n=15+−9n

−5m=−9n+15

Step 2: Divide both sides by -5.

-5m/-5 = -9n+15/-5

m= 9/5 n - 3

5. Given that 2x+329, the range of values of x is<br>(1 Point)

asambeis [7]

Answer:

The range of 2x+329:

$\mathrm{Range\:of\:}2x+329:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

Step-by-step explanation:

Given the expression

$2x+329$

We know that range is termed as the set of values of the dependent variable for which a function is defined.

We also know that the range of polynomials with odd degree is all the real numbers.

i.e. $-\infty \:$

The given expression is a polynomial with an odd degree. Hence, the range of this expression will be all the real numbers.

Thus, the range of 2x+329:

$\mathrm{Range\:of\:}2x+329:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$
