Answer:
x^2 + y^2 - 8x + 18y + 48 = 0
Step-by-step explanation:
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the centre of circle and r is the radius of circle. hence the standard form of equation can be obtained by expanding
(x-4)^2 + {y-(-9)}^2 = 7^2
Answer:
see explanation
Step-by-step explanation:
Given that S varies inversely as G then the equation relating them is
S =
← k is the constant of variation
To find k use the condition S = 7 when G = 1.8, then
k = SG = 7 × 1.8 = 12.6
S =
← equation of variation
When G = 3, then
S =
= 4.2
The answer is 78.5 you can get this by multiplying pi by the radius which is 5 then square it and you get 78.5
Answer: 60 degrees / 360 = 1/6
the arc is (1/6)(2pi)radians
