The average blood alcohol concentration (bac) of eight male subjects was measured after consumption of 15 ml of ethanol (corresp

onding to one alcoholic drink). The resulting data were modeled by the concentration function c(t) = 0.0225te−0.0467t

Answer:

The answer is 0.01365.

Explanation:

C(t) = 0.0225te^?0.0467t

We can derivate,

C'(t) = d/dt ( 0.0225 te^-0.0467t)

after solving,

C'(t) = 0.0225 (e^-0.0467t  - (0.0467e^-0.0467t . t)

Plug in t =5,

Answer is C'(t) = 0.01365.

The amount of radioactive carbon-14 in a sample is measured using a Geiger counter, which records each disintegration of an atom
sergij07 [2.7K]

Answer:

4121 years

Explanation:

From;

0.693/t1/2 = 2.303/t log No/N

t1/2= half life of the carbon-14

No= count rate of the living tissue

N= count rate of the sample

t = age of the sample

0.693/5730 =2.303/t log (13.5/8.2)

1.21 * 10^-4 = 2.303/t * 0.2165

1.21 * 10^-4 = 0.4986/t

t = 0.4986/1.21 * 10^-4

t = 4121 years

How do the differences in the polyatomic ions po3 3- and po4 3- help you determine whether each ends in -ite or -ate?
Tcecarenko [31]

There is a rule in naming polyatomic anions containing oxygen. Those names ending in <em>–ate</em> are given to the most common oxyanion of an element. While those names ending in <em>–ite</em> are for those that contains fewer O atom for the same charge. Since PPO_{3} ^{3-} has fewer O atoms, its name ends in <em>–ite</em>. Thus, PPO_{3} ^{3-}  is phosphite while PPO_{4} ^{3-}  is phosphate.
