Answer:
B 160,000 sq ft
Step-by-step explanation:
2018 is 13 years after 2005.
Put x=13 in the equation and evaluate:
... y = 0.538·13 +9.02 = 6.994 +9.02 = 16.014
This is the number of 10,000 sq ft, so the required area is ...
... 16 times 10,000 sq ft = 160,000 sq ft.

Answer:
Compare x^2 +y^2-8x-6y=75 with the general circle equation x^2+y^2 -2ax-2by+c=0
-2a =-8 And -2b=-6
a=4 b=3
c=-75
To find the radius use the equation
r^2=a^2+b^2-c
r^2=4^2+ 3^2-(-75)
r^2=25+75=100
r=10(radius is always positive)
Hence the center is (4,3) and radius 10
