Answer:
(x+9)^2 + ( y-2) ^2 = 25
Step-by-step explanation:
The equation of a circle can be written as
(x-h)^2 + ( y-k) ^2 = r^2 where ( h,k) is the center and r is the radius
(x--9)^2 + ( y-2) ^2 = 5^2
(x+9)^2 + ( y-2) ^2 = 25
Answer:
25+4+120(2min) = 149
25/149 = 0.16778523489932885906040268456376
= (rounded) 0.17
Answer: 90km/hour
Step-by-step explanation:
The formula for speed is given as:
= Distance / Time
where,
Distance = 120km
Time = 80 minutes = 80/60 = 1 1/3 hours
Speed = Distance / Time
= 120 / 1 1/3
= 120 / 4/3
= 120 × 3/4
= 90km/hour
The speed is 90km/hour.
Answer:
m = -6
Step-by-step explanation:
-8m + 4 = 52
-8m = 48
-8m/-8 = 48/-8
m = -6
