Suppose a robot is trying to get out of a maze. At the start of the maze, there are 2 choices of where to go. Along one path, the robot will take 1-6 minutes (uniform, like a fair die roll) and then return to the start. Along the other path, the robot will take 3 minutes and escape the maze. Every time the robot returns to the start, the robot chooses which path to take at random without remembering what happened before. Find the expected time until the robot escapes.

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

the answer is c hope it

step-by-step explanation:

is this part of a question or something

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
