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:
The area of the parallelogram is .
Step-by-step explanation:
Let's rewrite these two vectors:
Let's recall that the area of the parallelogram is the magnitude of the cross product between these vectors.
We can use the Determinant method to find it.
Now, the magnitude is the square root of each component squared. It will be:
Therefore the .
