Answer:
Center: (9, 4)
Radius: 20
Explanation:
(x - 9)² + (y - 4)² = 400
The Circle Formula:
(x - h)² + (y - k)² = r²
where (h, k) is center points, r is radius
Rewrite the equation:
(x - 9)² + (y - 4)² = 20²
Identify following:
h = 9, k = 4, radius = 20
Answer:
Repeaters.
Step-by-step explanation:
This is essential to effective communication because your EMS system must use Repeaters.
These are machines used to carry signals across a great distance. We may be in ambulances or put around an EMS network in different areas. The repeater receives and re transmits signals from lower power systems, such as mobile and handheld phones, to a higher power.
1.true
2.true
3.because it supposed to be 4 sides like a rhombus
I’m not sure if they are right
I believe x is 30 degrees.
The equilateral triangle has each angle equal to 60 degrees. So the small arc near x is also 60. The angle x is half the arc so would be 30.
This also makes sense because the triangle it forms with angle x and the center has center angle of 60 and angle formed by tangent and radius of 90. So it is a 30-60-90 triangle, making angle x 30.
Area of square=side^2
area=112
112=side^2
sqrt both sides
√112=side
4√7=side
4√7 ft is each side
