Answer:
Step-by-step explanation:
x²+y²-2x-10y+1=0
compare with x²+y²+2gx+2fy+c=0
center is (-g,-f)
radius=√(g²+f²-c)
2g=-2
g=-1
2f=-10
f=-5
radius=(1,5)
c=1
let eq. of circle be x²+y²-2x-10y+c=0
∵ it passes through (2,-3)
2²+(-3)²-2(2)-10(-3)+c=0
4+9-4+30+c=0
c=-39
eq. of circle is is x²+y²-2x-10y-39=0
Answer: The answer is the last one. Hope this helps!
Answer:
m=5
Step-by-step explanation:
first you would add 10m to both sides giving you -15+4m=5, then you add 15 to both sides giving you 4m=20 then you divide by 4 on both sides giving you m=5
-5 + x/22 = -1
+ 5 for both side
x
--- = 4
22
multiply by 4
x = 22(4)
x = 88
Answer: The required probability is 0.82.
Step-by-step explanation:
Since we have given that
Number of projects = 3
So, probability of getting each project = 
Probability of first path being completed in 43 days = 0.7
Probability of second path being completed in 43 days = 0.85
Probability of third path being completed in 43 days = 0.90
So, Probability that the project will be completed on time would be

Hence, the required probability is 0.82.
