Leah took her friends for a ride in her hot air balloon. The function f models the height of the hot air balloon about the ground ( in meters) as a function of time (in minutes) after takeoff.

1. are the triangles similar and if so why? what is the value of x? show your work.

Which of the following pairs of functions are inverses of each other? o a. f(x)=x72+8 and 96-9 = 7/x+2) =8 o b. f(x)= 6(x - 2)+3 and g(x) - *#2-3 o c. $4) = 5(2)-3 and 90- 4*: 73 o d. f(x) = 6)-12 and 910 – +12

The circle below is centered at the point (3, 1) and has a radius of length 2. what is the equation?
