Answer:
The area of the room and its uncertainty in square meters is:
15.642±0.040 
Step-by-step explanation:
We know the area of a rectangular room is the multiplication of the length and width:

Now we need to know the uncertainty, the uncertainty of a multiplication is:
(1)
: Area uncertainty
: Length uncertainty
: Width uncertainty
A: Area of the room
L: Length
W: Width
Clearing the uncertainty of the area:
(2)


The area of the room and its uncertainty in square meters is:
15.642±0.040 
Answer:
Step-by-step explanation:
Answer:
= 100
Step-by-step explanation:
The number of visitors is modeled by the expression 
Where m is the number of months after the number of visitors was measured.
We need to evaluate the above expression for m = -2.
So,

At m = -2, the value of the above expression is equal to 100.
Given that the first time a census was taken in Esinville, the population was 12,621, then the <span>coordinates of the point that contains the y-intercept is (0, 12,621)
