Answer:
A
Step-by-step explanation:
Sin(x) is odd while cos(x) is even (because f(x)=f(-x)
Answer:
18
Step-by-step explanation:
Total Surface Area of the Metal Sheet =
Given a cylinder with diameter 3 Inch and height 
To determine how many whole cans can be made, the first step is to find the total surface area of each of the cylindrical can.
Total Surface Area of a cylinder =
- Height of the can =

<u>Total Surface Area of each can </u>

<u>Number of Cans that can be Made </u>
To determine this, we divide the total surface area of the metal sheet by the total surface area of each can.
Number of Cans=Total surface area of the metal sheet÷Total surface area of each can.

Therefore, the company can make 18 whole cans from each sheet of metal.
Answer:
32760 ways
Step-by-step explanation:
Given
Number of Candidates = 15
Job Positions = 4
Required:
Number of outcomes
This question represent selection; i.e. selecting candidates for job positions;
This question can be solved in any of the following two ways
Method 1.
The first candidate can be chosen from any of the 15 candidates
The second candidate can be chosen from any of the remaining 14 candidates
The third candidate can be chosen from any of the remaining 13 candidates
The fourth candidate can be chosen from any of the remaining 12 candidates
Total Possible Selection = 15 * 14 * 13 * 12
<em>Total Possible Selection = 32760 ways</em>
<em></em>
Method 2:
This can be solved using permutation method which goes thus;

Where n = 15 and r = 4
So;
becomes





<em>Hence, there are 32760 ways</em>
