In conditional statements, "If p then q" is denoted symbolically by "p q"; p is called the hypothesis and q is called the conclusion. For instance, consider the two following statements: If Sally passes the exam, then she will get the job. If 144 is divisible by 12, 144 is divisible by 3.

Answer:
The answer to your question is $1.29
Step-by-step explanation:
Data
Total amount of cupcakes = 50
Total amount of sugar = 3 1/2 cups = 3.5 cups
Cost of 5-pound bag = $3.69
2 cups = 1 pound
Total cost = ?
Process
1.- Calculate the amount of pounds needed
                   2 cups ------------------ 1 pound
                   3.5 cups ---------------  x
                   x = (3.5 x 1) / 2
                   x = 3.5 / 2
                   x = 1.75 pounds
2.- Calculate the price of 1.75 pounds
                   5 pounds -------------- $3.69
                   1.75 pounds ----------    x 
                   x = (1.75 x 3.69)/5
                   x = 6.46/5
                  x = $1.29
3.- Conclusion
The cost of sugar to prepare 50 cupcakes is $1.29
 
        
             
        
        
        
15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2
