Answer:
The cost of the mug is of $6.50.
Step-by-step explanation:
The cost of the mug and r refills is given by the following equation:
Cost of the mug:
The cost of the mug is found when no refills are bought, that is, C when , which is
The cost of the mug is of $6.50.
One person throws away 4.5 x 10² g/day.
In 2013, there were 3.2 x 10⁶ people, so they threw away
(4.5 x 10² g/day)*(3.2 x 10⁶) = 1.44 x 10⁹ g/day.
Assume that there were 365 days in 2013.
The total trash thrown away was
(1.44 x 10⁹ g/day)*(365 days) = 5.26 x 10¹¹ g
Answer: 5.3 x 10¹¹ g
Given
on the interval 0 ≤ x ≤ 7, for maximum value, f'(x) = 0.
Answer:
Given sides 12, 16 and 20 can be the sides of right triangle.
Step-by-step explanation:
Sides of right triangle always follow the Pythagoras theorem.
i.e
For the given Lengths 7, 40 and 41
We need to check if
That means,
hence 7,40 and 41 can not be the sides of right triangle.
Next,
Given sides 12,16 and 20.
Again follow the similar process used in the above problem.
Therefore given sides 12,16 and 20 can be the sides of right triangle.
