C = 2 * 3.14 * 4 = 25.1 to nearest tenth ( 1 decimal place)
Answer:
(x + 1)² + (y - 1)² = 1.5625
Step-by-step explanation:
From the picture we see:
The radius is 5 units. Each unit is .25 so the radius is 1.25.
The centre or middle M= ( -1, 1 )
Circle with centre M and radius r :
(x - xM)² + (y - yM)² = r²
xM = -1
yM = 1
r = 1.25
(x - (-1))² + (y - 1)² = (1.25)²
(x + 1)² + (y - 1)² = 1.5625
Answer:
26km
Step-by-step explanation:
d=speed × time
d=60×2.33
d= 140km
Answer:
d≈3.5
Step-by-step explanation:
