Answer:
i think its personally B
Step-by-step explanation:
Hello,
When you compose 2 reciprocals functions, you will find 1.
ex f(x)=√x and g(x)=x² , x>=0
so that g(f(x))=(√x)²=x
sin(cos(0))=sin(1)=0,84147... rad and not 1.
Reciprocal function of sin (x) is arcsin(x).
Reciprocal function of cos (x) is arccos(x).
Angle C is 40degree
Then Angle B is supposed to be 180-90-40 which will be 50 degree
Question 9 is A, and question 10 is 10^5.
1 pound is 16 ounces so multiply by .30 to get 4.80 times 2 bc theres 2 pounds which will be $9.60
