The correct question is:
A circle has a radius of 45 units and is centered at (-2.4, -4.8).
What is the equation of this circle?
Answer:
Equation of the circle is;
(x + 2.4)² + (y + 4.8)² = 2304
Step-by-step explanation:
The standard equation of a circle is;
(x - a)² + (y - b)² = r²
where;
(a,b) is the center of the circle and r is the radius of the circle
Now, from the question, the circle is centered at (-2.4, -4.8) and the radius is 45
Thus, plugging those values into the standard form of equation of a circle, we have;
(x - (-2.4))² + (y - (-4.8))² = 48²
This gives;
(x + 2.4)² + (y + 4.8)² = 2304
Answer:
531441/4
Step-by-step explanation:
Answer:
4 mins 31 seconds
Step-by-step explanation:
Maximum speed is 203 mph equivalent to
Time taken to attain maximum speed, 
where v is velocity and a is acceleration hence
The distance traveled when at top speed
Total distance is provided as 12.42 miles converted to ft is 12.42*5280=65577.6 ft
Total distance-distance moved to attain maximum speed will be
65577.6 ft-15127.2 ft=50450.44 ft
Time taken during maximum speed
Total time=101.6155 s+169.45 s=271.06 s
271.06/60=4 mins 31 seconds
