17.76(5) = 88.15 + 27.52 = 115.67
Answer is A
Disjoint events are those which do not have any outcome in common. From the given options only option D represents such an event.
Spinning a number less than 4 will result in 1,2 or 3 as outcome. Second event is getting a 6. So these two events do not have anything in common.
Thus, the answer is option D

Answer:
f^-1(x) is a function
Step-by-step explanation:
To get the inverse you replace f(x) with y, so you get y=3x^2+2. Then you switch your x and y to get x=3y^2+2. Now you want to solve for y, so you subtract two to get x-2=3y^2. You then divide both sides by 3 to get (x-2)/3=y^2. Finally you square root both sides to get y=√((x-2)/3). Now you get that f^-1(x)=√((x-2)/3). When you graph it you can see that the graph passes the vertical line test, so f^-1(x) is a function.
