Solution,
The equation of tangent to a circle with radius 'r' is given by:
x • x1 + y• y1= r^2
where (X1,y1) are point of intersection.
Therefore, the equation becomes:
8x+15y= (17)^2
8x+15y= 289
15y = -8x+289
y= -8/15 x +289/15
Hope this helps..

Answer:
the probability is 0.28
Step-by-step explanation:
using Bayes's theorem
P(A|B)=P(A∩B)/P(B)
where
P(A∩B) = probability that events A and B happen
P(A|B) = probability that event A happen if B already happened
P(B)= probability of event B
therefore
P(A∩B)=P(A|B)*P(B)
if event A= selection of a student that lives in a dormitory and event B = selection of a freshmen student
P(A|B) = 0.8 (live in a dormitory knowing that is a freshmen student )
P(B) = 0.35 (freshmen student)
P(A∩B)=P(A|B)*P(B) = 0.8* 0.35 =0.28
