Answer:
{r|r>0}
Step-by-step explanation:
Pressure is the amount of force exerted on a surface per unit area, P=F/A.
The pressure, in atmospheres (atms), of a liquid on the circular base of a bucket is represented by the composite function PoA(r), where P(A) = 375 / A and A (r) = pi r²
We know that the domain is the set of input values.
Pressure,
At r = 0, it becomes not defined.
It means that r can be any value that is greater than 0. Hence, the correct option is (c). i.e. {r|r>0}
Answer:
x = 120
Step-by-step explanation:
First you want to get the equation into the form cosx = a
2 cos=1
Divide both sides by two to get it into the form.
cos=
Now, on your calculator, use the inverse of cos, to solve for .
=
(
)
= 60
Now you want to find x, so multiply both sides by 2.
x = 60 * 2 = 120
x can have many solutions; however, I have only given you one.
