Actually Welcome to the Concept of the Inverse Trigonometry Function.
So here, we get as
SinX = 1/2
X = Sin^-1(1/2)
X= 30°
Answer:
1.5000000000000000000
Step-by-step explanation:
The mean will be calculates as follows; from the formula of z-score we shall have:
z=(x-μ)/σ
the z-score associated with 0.5% is 0
thus
0=
(8-μ)/0.4=0
solving for x we get:
μ=9
Answer: μ=9
Answer:
Wait I just realized, none of them are cubic? for a polynomial to be cubic it needs to be 
The slope is 1 because it is parallel and y=x+b, so, 2=-3+b and b=5
y=x+5
