Answer:
$72.5
Step-by-step explanation:
- Initial value = $200
- Depreciated value after 4 years = $115
<u>Since depreciation rate is linear, then:</u>
- 200 - 4x = 115
- 4x = 200 - 115
- 4x = 85
- x = 85/4
- x = 21.25
<u>Value after 6 years:</u>
- 200 - 6*21.25 = 200 - 127.5 = $72.5
Answer:
5) 3x - 10 = x + 4
answer: 7
6) 6x + 4 = x - 11
answer: -3
Step-by-step explanation:
3x - 10 = x + 4
x = 7
6x + 4 = x - 11
x = -3
Answer:
<h2>C(V(r)) = 3.2πr3</h2>
Step-by-step explanation:
This problem is a composition of function defined by C(V(r)), now we have the functions 
and 
, where the first depends on the radius, and the second dependes on the volume, that means, to find the number of ounce of coffe, we need to determine the volume of the cylinder, that's why we have to replace the volume function inside the ounces function,
Therefore, the right answer is the last choice.
