Ans: D
differentiate sinx=cosx and differentiate x=1
:)
1: multiple both sides by 2
Ex:-7n+10=-32
2: subtract 10 from both sides
Ex: -7n=-42
3:divide both sides by -7 to get n alone
Ex: n=6
Answer is 6 and the process is elimination!
3x-12 = 12x
-12 = 9x
-12/9 = x
x= -4/3
Answer:
c
they will both have to intersect since you have a negative and positive number. Hope it helps.

Step-by-step explanation:
12P3 = 12! / (12-3)!
= 12*11*10
= 1320.
