Please help with this question

3.75% per year and 7.5% per two years

Step-by-step explanation:

The work is shown below:

1600-100=1500

1500/2=750

100+750=850

1600-750=850

750=7.5%

7.5/2=3.75 per year

Hence, the percentage increase or decrease is 3.75%.

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
