Use dot product
a=(x1,y1) and b=(x2,y2)
a.b=/a/*/b/ cos x
a.b mean dot product of two vectors
a.b is equals x1*y1+x2*y2
Answer:
yay
Step-by-step explanation:
If cente ris (h,k) and radius is r then
equatn is (x-h)^2+(y-k)^2=r^2
so
center (5,4)
r=2
h=5
k=4
(x-5)^2+(y-4)^2=2^2
(x-5)^2+(y-4)^2=4
first option
