Answer:
Download Photo math for help, it works really well and it shows the work.
<span>Completando cuadrados seria x ^ 2 + 10x + 25 + y ^ 2-4y = 20 + 25 + 4
<span>factorizamos (x + 5) ^ 2 + (y-2) ^ 2 = 49
pero como 49 es (7) ^ 2 lo Escribimos de la siguiente manera
(x + 5) ^ 2 + (y-2) ^ 2 =</span></span> (7) ^ 2
Donde diametro es 2R=D, aplicamos la formula anteriior; 2(7)=D
D=14
.066
1 Centimeter = 0.03280839895 Feet
You would take delta y over delta x
(8-4)/(8-4) and it would be 1.
the slope is 1
1/10 which is 10%
Hope this helps
Have a great day/night
