Answer:
2x+3(10+x)
Step-by-step explanation:
I'm not sure but I think this might be the answer
I think its 1.012(500 - 100) = 400* 1.012 = 404.80 dollars
Answer:
A (no because the graph is not a straight line)
Step-by-step explanation:
The rate of change is not consistent, and therefor is not proportional.
Answer: 11.76%
Step-by-step explanation:
- 10:85*100=
- (10*100):85=
- 1000:85=11.76%
So, 11.76% is the answer.
*Hope this helps!! Mark me brainliest :)
Let x be the height of the box and y be the length of one side of the base then:-
V = xy^2 = 108
x = 108/y^2
Surface area = y^2 + 4xy
S = y^2 + 4y* 108/y^2
S = y^2 + 432/y
Finding the derivative:-
dS/dy = 2y - 432/y^2 = 0
2y^3 = 432
y^3 = 216
y = 6
Check if this gives a minimum value:-
second derivative = 2 + 864/y^3 which is positive so minimum.
V = xy^2 = 108
36y = 108
y = 3
Answer :- dimensions of the box is 3*6*6 metres
