Step-by-step explanation:
Given

Required
Determine the domain and the range
Solving for domain:
From the question, we understand that t represent years.
Because years can't be negative;
Then, we can conclude that the domain, t is:

Solving for Range:
We solved domain to be 
This implies that the minimum value of t is
and the maximum is infinity
Substitute 0 for t in 



Hence;
The range is

Answer:
184 in²
Step-by-step explanation:
Given :
Width, w = 6 inches
Length, l = 10 inches
Height, h = 2 inches
To obtain how much wrapping paper is needed ; we take the surface area of the box
Surface area = 2(lw + lh + wh)
Surface area = 2((6*10) + (6*2) + (10*2))
Surface area = 2(60 + 12 + 20)
Surface area = 2(92)
Surface area = 184 in²
The amount of wrapping paper needed = 184 in²
Step-by-step explanation:
the volume is 4/3 × pi × r^3
4/3 × 3 × 4^3
the volume is 256 cm cubed.
the radius is 4 cm.
