Your goal is to get an equation with just the variable r on one side. The first variable you
should move is t. Subtract it from both sides:Next, get rid of the radical sign on the left side by squaring both sides:You can get rid of the denominator on the right side of the equation by multiplying both
sides by q:Finally, to get r alone on the right side, take the cube root of each side:20 . B
The hyperbola is centered at the point (h,k).So h = −2 and k = 3; the hyperbola is centered at (−2,3).21 . B
To find the value of n^18 , determine what operation was performed on n^6 . Then see whether
performing the same operation on 3n gives you one of the results found in the answer
