Answer:
(x + 7)^2 + (y + 3)^2 = 4
Step-by-step explanation:
The standard equation of a circle is:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius. We can substitute the information given to obtain:
(x + 7)^2 + (y + 3)^2 = 4
Answer:
A. 400*45.2=400*45+400*0.2=18000+80=18080
B. 14.9*100=15*100-0.1*100=1500-1=1490
C. 76.2*200=76*200+0.2*200=15200+4=15204

Answer:
C
Step-by-step explanation:
Since there are two arcs and they both make up a circle, and a circle has 360 degrees.
NPL+NL=360
The measure of NPL is twice the measure of NL so
it now
2NL=NPL
Substitute that in the equation
2NL+NL=360
3NL=360
NL=120
Since NL subtends NML they are equal so NML=120
