Answer:
0
Step-by-step explanation:
(sin(2n) − 1) / (sin n − cos n)
-(1 − sin(2n)) / (sin n − cos n)
-(1 − 2 sin n cos n) / (sin n − cos n)
-(sin² n − 2 sin n cos n + cos² n) / (sin n − cos n)
-(sin n − cos n)² / (sin n − cos n)
-(sin n − cos n)
cos n − sin n
Limit as n approaches π/4 is 0.
So 5/8 of $24
5/8 * 24
15
Joshua spent $15.
Hope this helps :)
Answer:
No
Step-by-step explanation:
(x,y)=(4,-1)
73x+5y=7
73*4+5*(-1)=287
____________________________
175x−3y=17
175*4-3*(-1)=703
Answer: It is exactly 85.7142857143
But if you would like it rounded: 85.7
I would go with the second answer.
