Answer:
Circumference ≈ 82.9
Step-by-step explanation:
The formula for calculating the circumference of a circle is:
C = 2πr
Where 3.14 is pi (as stated on your screen)
And r is the radius.
Knowing this substitute those values
C = 2(3.14)(13.2)
Multiply 2 and 3.14.
C = (6.28)(13.2)
Multiply 6.28 and 13.2.
C = 82.9 when rounded.

Suppose we choose a path along the

-axis, so that

:

On the other hand, let's consider an arbitrary line through the origin,

:

The value of the limit then depends on

, which means the limit is not the same across all possible paths toward the origin, and so the limit does not exist.
Answer: 5/3(a)^6
Step-by-step explanation:
Answer: 0.42 mg
Step-by-step explanation:
Given : A 3mL unit dose of levalbuterol HCl contains 0.63mg of active ingredient.
Then , the amount of active ingredient in 1 ml dose of levalbuterol HCl = 

Hence, the amount of active ingredient in 2 ml dose of levalbuterol HCl will be :-

Hence, the amount of active ingredient in 2 ml dose of levalbuterol HCl =0.42 mg
Answer: 42
Step-by-step explanation:
if the bookstore has 64 copies,
yesterday it was sold 1/4 , so it was sold 64/4=16
today it was sold 1/8 from what remained, which is 6(see below)
64-16=48
48/8=6
the store has left 48-6=42
