Length of circular track is:
L = 2*r*pi
He run 3/4 of it so length is:
L' = 3*2/4*r*pi = 3/2*r*pi
To calculate speed of his movement we use formula:
v = s/t where s = L' and t = 1 minute 45 seconds = 105 seconds
v = L'/t =

v = r* pi/70
If we take that r = 1 answer is
Answer:
-3 and 2
Step-by-step explanation:
put : x = - 3 in this equation : x - 6 = -x².
- 3 - 6 = - (- 3)²
-9 = -9 .....true
now put x = 2
2 - 6 = - (2)²
- 4 = - 4......true
(4 x 100) + (1 x 10) + (2 x 1) + (6 x 0.1) + (3 x 0.01) + (8 x 0.001)
<h2>-0.71 is it i think so i dk </h2>
