The answer should be either 2.5 x 10^4 or 2.1 x 10^4.
But I feel 2.5 x 10^4 is a better estimate.
Hope it helped :))
Answer: x= 58/63 or x= -40/63
Step-by-step explanation: thats your answer.
The answer to your question would be 'A'
Answer:
y² - (K- 2)y + 2k +1 = 0
equal roots means D=0
D= b^2 - 4ac
a=1, b= (k-2), c= 2k+1
so,
(k-2)^2 - 4(1)(2k+1) = 0
=> k^2 +4 - 8k -4 = 0
=> k^2 -8k = 0
=> k^2 = 8k
=> k= 8k/k
=> k = 8
Therefore the answer is k= 8

In my opinion, the correct answer among the choices listed above is option B. A sphere made up of many circular cross sections. When you cut through a plane at any angle or side, you will see that the plane made will always be a circle.
