For example f(x) is a negative g(x) plus some simple function.
g(x) = 1/ (x-a)
f(x) = (-1)/(x-a) + x
Answer:
Step-by-step explanation: If Professor Lam grades 4 papers per hour, in 11 hours he will graded 44 papers. (11 x 4= 44). He had previously graded 6 papers giving him a total of 50 papers graded. His assistant can grade 5 papers per hour, thus it would take him 10 hours to grade the same amount of papers as Professor Lam. (10 x 5= 50) Thus: 11 hours Professor Lam 50 papers graded; 10 hours his assistant 50 papers graded.
Finding the value of x and y.
x:
sin 30 = 1/x
x = 1/sin 30
x = 2
y:
cos 30 = y/2
2(cos 30) = y
1.73 = y
Now the table:
sin 30 = 1/2
cos 30 = 1.73/2
tan 30 = 1/1.73
sin 60 = 1.73/2
cos 60 = 1/2
tan 60 = 1.73/1
Hope this helps :)
