Answer:
y=4.5x
Step-by-step explanation:
It's right on Khan Academy:)
This means area of the park is in between the two numbers so we can write:
2.4 + 2.5 /2
= 2.45
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}
