REY [17]

Answer:

Yes, k = 1/3 and y = 1/3x

Step-by-step explanation:

\text{The given line passes through the origin, hence it has equation of the form:}\\y=kx

\text{Therefore y varies directly as x.}The line passes through the point (3,1)}

\text{This implies that,}

1=k(3)\\k=\frac{1}{3}\text{Hence the constant of variation is} ⇒ \frac{1}{3}

The equation would be ⇒ y=\frac{1}{3} x

Find the value of arccos0
gayaneshka [121]

Answer:

Step-by-step explanation:

arccos(0) = 90 degrees

Cos is 0 when ever sin(x) =-1 this occurs at 270 degrees and when sin(x) = 1 at 90 degrees. However, the domain of arccos(x) is restricted from 0 to pi. So the value of arccos(0) is pi/2 or 90 degrees.
