Anybody know the answer???

kap26 [50]

The three angles are 45, 75, and 60. The sides across from these angles correspond to the length of the sides. Since 45 < 60 < 75, MN < ON < MO. The answer is therefore C. MN, ON, MO.

Hope this helps!

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:
$A=A _{0} e^{-0.693t}$
