Answer:
(2, -3)
Step-by-step explanation:
Compare the given (x-2)2+(y+3)2=9 to the standard equation
(x - h)^2 + (y - k)^2 = r^2.
It becomes obvious that h = 2, k = -3 and r = 3.
The center of this circle is (h, k): (2, -3).
Answer:
Surface area of prism is 48km^2
Amplitude : 2/3
Period : 3pi/2
The probability that a randomly selected cable repair visit will take at least 43 minutes will be 88%.
Given: The times required for a cable company to fix cable problems in its customers' homes are uniformly distributed between 40 minutes and 65 minutes.
It can be deduced that the probability that a randomly selected cable repair visit will take at least 43 minutes will be calculated thus:
= 1 - [(43 - 40)/(65 - 40)
= 1 - 0.12
= 0.88
Hence, The probability that a randomly selected cable repair visit will take at least 43 minutes will be 88%.
