Answer: the sets that cannot represent the three sides of a triangle are: [15,27,44]
Step-by-step explanation: because you add the 2 smallest numbers so in this you would add 15 + 27 and it equals 32. so therefore the number that you get from adding 5 and 27 or any small number would have to be bigger then the third number.
Answer:
Seven out of ten
Step-by-step explanation:
C) 2/9 , because dividing both 8 and 36 by 4 will leave the numerator as 2 (8/4=2) and the denominator as 9 (36/4=9).
So, f[x] = 1/4x^2 - 1/2Ln(x)
<span>thus f'[x] = 1/4*2x - 1/2*(1/x) = x/2 - 1/2x </span>
<span>thus f'[x]^2 = (x^2)/4 - 2*(x/2)*(1/2x) + 1/(4x^2) = (x^2)/4 - 1/2 + 1/(4x^2) </span>
<span>thus f'[x]^2 + 1 = (x^2)/4 + 1/2 + 1/(4x^2) = (x/2 + 1/2x)^2 </span>
<span>thus Sqrt[...] = (x/2 + 1/2x) </span>
