• ### Is the point (−1,−2,2) visible from the point (6,7,0) if there is an opaque ball of radius 1 centered at the origin?

Is the point (−1,−2,2) visible from the point (6,7,0) if there is an opaque ball of radius 1 centered at the origin? I think it is yes because I got the t is bigger than 1. But I have trouble on the problem 2. ------------------------------------------------------------------------------- Suppose that you stand at the point (6,7,0) and look in the... show more
Is the point (−1,−2,2) visible from the point (6,7,0) if there is an opaque ball of radius 1 centered at the origin? I think it is yes because I got the t is bigger than 1. But I have trouble on the problem 2. ----------------------------------------... Suppose that you stand at the point (6,7,0) and look in the direction of a point that is not visible because it is behind the ball. You will then be looking at a point on the sphere. If (−1,−2,2) is not visible from (6,7,0), find the point on the sphere at which you are looking if you look in the direction of (−1,−2,2). Otherwise, find the point on the sphere at which you look if you are looking in the direction of (−1,−2,1). Point (x,y,z)= ___ I got: (7t+6)^2+(9t+7)^2+(2t)^2=1 but t is -1/134 (-105-sqrt(231)) or 1/134 (-105-i sqrt(231)). When i plug it in the line equation, I got something really weird and the answer was marked as wrong.... Please help!!! Any clue will be great help!
