Answer:
(x + 4)² + (y - 9)² = 25
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) = (- 4, 9) and r = 10 ÷ 2 = 5, thus
(x - (- 4))² + (y - 9)² = 5², that is
(x + 4)² + (y - 9)² = 25
Answer:
The equations describing the area which each tower covers are given as
Tower A :
Tower B :
Tower C :
Step-by-step solution:
Cell phone radio towers broadcast a cell phone signal in circular pattern
Tower A at Adele Acres have position co-ordinates as (0,0) and a coverage radius of 4 ml. So, the area which it covers is given by the equation,
-------------------------------(1)
Tower B at Brown Lake have position co-ordinates as (5,4) and a coverage radius of 3 ml. So, the area which it covers is given by the equation,
-------------------------------(2)
Tower C at Cady City have position co-ordinates as (4,-4) and a coverage radius of 5 ml. So, the area which it covers is given by the equation,
-------------------------------(2)
Answer:
<OMP = 76 degrees
Step-by-step explanation:
since LMN is a straight angle, the angles must all add up to 180 degrees.
so 37 + 67 = 104
180 - 104=76 degrees
