Alexi’s restaurant bill is $58, and he wants to leave a 20 percent tip. which expression represents the total amount that alexi needs to pay?

Acircle has a radius of 5/6 units and is centered at (3.6, 7.8) write the equation of this circle

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright

Can someone me with these two circle theorem questions asap?
