Answer:
0.15
Step-by-step explanation:
20-5=15. So move the decimal!
Answer:
B) Sin^-1(-1) = 3pi/2 or 270°
D) Sin^-1(-1) = -pi/2 or -90°
Step-by-step explanation:
Sine function:
The sine function is -1 at 270º(-90º), which is 3pi/2 = -pi/2.
Inverse sine:
The input of the inverse sine function is a value, and the output are the angles which have the sine equal to the input.
Sin^-1(-1)
Angles for which the sine are -1, that is 3pi/2 or 270° and -pi/2 or -90°. Thus, options B and D are correct.
The answer is 20, since it’s heads and tails you have a half and half chance, therefore you divide 40 in half and get 20
I think its -.338 if I understand the question right
