Answer:
account would be empty in 2 months
Step-by-step explanation:
No. To test whether a graph is a function or not you do the vertical line test where if a vertical line touches more than one point it is not a function
You will have to use trig to solve this:
The side you have is adjacent to the known angle
The side you are looking for is opposite the known angle
^^^This means you need to use tan:
tan(24) = 
.445222 = 
^^^input tan(24) into calculator, then multiply 12 to both sides to isolate and solve for x
5.3 ≈ x
