Answer:
2,575 grams of blood plasma are in the typical adult human body
Step-by-step explanation:
Density is the property that matter, whether solid, liquid or gas, has to compress into a given space, so it relates the amount of mass per unit volume. So the density of a substance is the quotient between mass and volume:

In this case, you know:
- density=1.03

- mass= ?
- volume= 2.5 L= 2,500 mL (being 1 L= 1,000 mL)
Replacing:

and solving, you get:
mass= 1.03
*2,500 mL
mass= 2,575 g
<u><em>2,575 grams of blood plasma are in the typical adult human body</em></u>
Step-by-step explanation:
y = (cos x)^(sin x)
Take log both sides.
ln y = ln ((cos x)^(sin x))
ln y = (sin x) ln (cos x)
Take derivative.
1/y dy/dx = (sin x) (1/cos x) (-sin x) + (cos x) ln (cos x)
dy/dx = y [ (cos x) ln (cos x) − sin x tan x ]
dy/dx = (cos x)^(sin x) [ (cos x) ln (cos x) − sin x tan x ]
Your answer is correct.
