Answer:
C) y=13+15x
Step-by-step explanation:
y=13+15x
Answer:
There are 33 students
Step-by-step explanation:
Because 7:4 should be in multiple of 11
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
