Answer:
The function is A = 10√r
Step-by-step explanation:
* Lets explain the meaning of direct variation
- The direct variation is a mathematical relationship between two
variables that can be expressed by an equation in which one
variable is equal to a constant times the other
- If Y is in direct variation with x (y ∝ x), then y = kx, where k is the
constant of variation
* Now lets solve the problem
# A is varies directly with the square root of r
- Change the statement above to a mathematical relation
∴ A ∝ √r
- Chang the relation to a function by using a constant k
∴ A = k√r
- To find the value of the constant of variation k substitute A and r
by the given values
∵ r = 16 when A = 40
∵ A = k√r
∴ 40 = k√16 ⇒ simplify the square root
∴ 40 = 4k ⇒ divide both sides by 4 to find the value of k
∴ 10 = k
- The value of the constant of variation is 10
∴ The function describing the relationship of A and r is A = 10√r
Answer:
361/1000
Step-by-step explanation:
this should be the answer
4600
Because the zeros aren’t significant unless they’re after a decimal point, but other numbers are significant.
It is clearly mentioned in the question that each bottle of ibuprofen has 1000 pills.
Now, 1/4 bottle of ibuprofen is used to make the prescription.
So, if one bottle of ibuprofen has 1000 pills and 1/4 1/4 bottle of ibuprofen is used to make the prescription, then Jerome obviously used 
pills of ibuprofen to make the prescription.
This can be further explained as follows:
1 bottle=1000 pills
bottle=
=250 pills.
