Volume=530.14 , rounded to the nearest whole number would just be 530 ft.
A9th = -1* 5^(n-1)
a9th = -1*5^(9-1)
a9th = -1*5^(8)
a9th = -390625
Hope this helps!
The answer would be 170,000 how you do it is you find wether or not you are above the number 5 if you are you go up to the nearest number. if you are below five you round down to the nearest number. (example: 5.8 you would round to 6)
The correct solution is shown in the graph (D)
Given that the budget is $24 and the minimum is 7 tubs, the fourth graph shows the area in which both constraints are satisfied: triangular area between the points
7 small tubs
8 small tubs
3 large and 4 small tubs
32 is my expression i think thats the correct answer
