Find the angle in degrees of the hands of a clock at 4:00.
$75^\circ$
$90^\circ$
$180^\circ$
$120^\circ$
What is the equation of a circle that has its center at $(5, \frac{1}{4})$ and a radius length of $\frac{1}{5}$?
$(x-5)^2-(y+\frac{1}{4})^2=\frac{1}{5}$
$(x-\frac{1}{4})^2+(y+5)^2=\frac{1}{25}$
$(x-5)^2+(y-\frac{1}{4})^2=\frac{1}{25}$
$(x-5)^2+(y-\frac{1}{4})^2=\frac{1}{10}$
