Answer:

Bar and lexical.

Explanation:

Bar and lexical are the name of two different types of scales that are found on maps. Bar scales are used more frequently in the maps because they represent or show the distance ratio visually instead of in words, while on the other hand, lexical scales may be expressed in words, as a ratio, or as a fraction. Examples are 1:10,000 or 1/10,000. Using map scales is very important in the real world if you want to find out the distance you are traveling.

g If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time

Elenna [48]

Answer:

a. 8.1 milligrams

b. 40.07 hours

c. 8.859 milligrams

Explanation:

If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time can be modeled by

$A_{t}=10e^{-0.0173t}$

Where A(t) = amount of Valium remaining in the blood after t hours

t = time or duration after the drug is taken

a. we have to calculate the amount of drug remaining in the bloodstream after 12 hours

$A_{12}=10e^{-0.0173\times12}$

$A_{12}=10e^{-0.2076}$

= 10×0.81253

= 8.1 milligrams

b. In this part we have to calculate the time when A(t) = 5 milligrams

$5=10e^{-0.0173\timest}$

$\frac{5}{10}=e^{-0.0173t}$

0.5 = $e^{-0.0173t}$

Now we take natural log on both the sides of the equation.

ln(0.5) = ln( $e^{-0.0173t})$

-0.69314 = -0.0173t

t = $\frac{0.69314}{0.0173}$

t = 40.0658

≈ 40.07 hours

c. In this part we have to calculate the rate, by which amount of drug will decay in the bloodstream after 7 hours.

$A_{7}=10e^{-0.0173\times7}$

$A_{7}=10e^{-0.1211}$

= 10×0.8859

= 8.859 milligrams

Len [333]

Answer:

Cellular respiration

Explanation:

The point of cellular respiration is to get energy for the cell. ATP is the "energy currency" of the cell that enables it to function at normal levels. In cellular respiration, a process called <u>glycolysis</u> breaks down glucose to obtain large amounts of ATP.
