Answer:

3/7r + 5/8s = 11

Step-by-step explanation:

r = 14

s = 8

3/7r + 5/8s = ?

3/7 (14) + 5/8 (8) = ?

3 x 2 + 5 = ?

6 + 5 = 11

Let log P/N=5 and log M/N=9<br> what is the relationship between P and M?

vova2212 [387]

we know that

log (P/N) = log P - log N
so
log P - log N = 5----------------> equation 1

log (M/N) = log M - log N
so
log M - log N = 9 ------------------> equation 2

If you subtract equation 2 from equation 1,
you have
log M - log P = 4
That means that log (M/P) = 4 ----> 10^4 = M/P ---> M = 10000P

the answer is
the relationship between P and M is
M = 10000P

Soon after taking an aspirin, a patient has absorbed 320 mg of the drug. after 3 hours, only 40 mg remain. find an exponential m

Anastaziya [24]

The equation will be of the form:
$A(t)= A_{0} e^{rt}$
where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:
$40=320e^{3r}$
Rearranging and taking natural logs of both sides, we get:
$ln\ 0.125=3r$
$r=\frac{ln\ 0.125}{3}=-0.693$
The required model is:
$A=A _{0} e^{-0.693t}$
