F(x) is a function.

True or false

I believe it is false.

Step-by-step explanation:

Because you can only have one number (like only one line can go across)

Hope my answer has helped you and if not I am sorry.

Its  true

Step-by-step explanation:

F stands for function.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
