Analyzing an Equation Given in General Form
Consider a circle whose equation is r y . Ar-by-36=0 which statements are
To begin converting the equation to standard form, subtract 36 from both sides
To complete the square for the terms, add 4 to both sides.
The center of the circle is at -2,3)
The center of the circle is at (4-6).
The radius of the circle is 6 units
The radius of the circle is 49 units

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. these cyclotrons typically accelerate h- (the hydride ion, which has one proton and two electrons) to an energy of 5 mev to 20 mev. this ion has a mass very close to that of a proton because the electron mass is negligible—about 1 2000 of the proton’s mass. a typical magnetic field in such cyclotrons is 1.9 t. (a) what is the speed of a 5.0-mev h-? (b) if the h- has energy 5.0 mev and b = 1.9 t, what is the radius of this ion’s circular orbit?
