Answer:
a. 114 minutes
b. 48 minutes 
Step-by-step explanation:
Given that 
Time spent over the piano is 75 minutes
a. if Priya practice violin for 152% as Han Practiced for piano
So the minutes she practice in Violin is 
= 75 minutes × 152%
= 114 minutes
Likewise
b. If Tyler practiced for clarinet for 64% as Han Practiced for piano
So the minutes he practice in Clarinet is 
= 75 minutes × 64%
= 48 minutes
The same is to be considered

❖ The length of the field is 91 m.
Divide to find the missing length:
 4641 ÷ 51 = 91

T+11 because total would mean add them
        
                    
             
        
        
        
Making the value of 'a' smaller, but still positive, will make the graph be compressed vertically. 
Let's say a = 1 is the initial value. If we update it to a = 0.5, then the graph will be half as tall as it used to be, so it's compressed by a factor of 1/0.5 = 2.
The value of b determines the period of the sinusoidal function.
