Answer:
(x - 8)² + (y + 9)² = 49
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
here (h, k ) = (8, - 9 ) and r = 7 , then
(x - 8)² + (y - (- 9) )² = 7² , that is
(x - 8)² + (y + 9)² = 49

ANSWER:
We know that,
Speed = Distance/Time
So, Time taken = 20kmh-¹/160km
Answer:
b=23
Step-by-step explanation:
(b+43)+(3b+45)=180
2 adjacent angles will always equal 180
Then just simplify
