Given that the function

models the concentration of a medication in the bloodstream (as a percent), hours (h) after its injection into muscle tissue.
The number of hours it will take for the concentration of the injection to be less than 0.5% is given by:

Given that the first injection was given at 8:00 am, the time the next injection should be given is 2 pm.
Answer:
1.6 feet
Step-by-step explanation:
The radius is 1/2 of the diameter.
0.8 * 2 = 1.6
Net?
I think we're being asked for the area of the shape.
2 4x4 squares and four 6x4 rectangles
2(4)(4) + 4(6)(4) = 32 + 96 = 128 square feet (that a lot of cardboard)
Answer:
they are congruent
Step-by-step explanation:
they have the same points
Answer:
Area: 28.26ft², Circumference: 18.84ft
Step-by-step explanation:
Area of a circle: πr²
Circumference of a circle: πd (or 2πr)
Since the diameter is 6ft, then the radius is half of that, which is 3ft. This means that our area is:
πr²
π(3)²
π(9)
9π
9(3.14)
28.26ft²
Our circumference is:
πd
π(6)
6π
6(3.14)
18.84 ft
