a) * Ta có: \(7\left(x-2\right)^2\ge0\)
\(\Rightarrow7\left(x-2\right)^2+2013\ge2013\)
Dấu "=" xảy ra khi \(x-2=0\Rightarrow x=2\)
Vậy Amin=2013 khi x = 2
* Ta có: \(5x^2\ge0\Rightarrow5x^2-9\ge-9\)
Tương tự
b) Ta có: \(3.\left(3-5x\right)^2\ge0\Rightarrow2015-2\left(3-5x\right)\le2015\)
Dấu "=" xảy ra khi \(3-5x=0\Rightarrow x=\frac{3}{5}\)
Vậy Cmax=2015 khi x = 3/5
1,25 + 2,75 + 4,25 + 5,75 + 7,25 + 8,75 + 10,25 + 11,75 + 13,25 + 14,75 + 16,25
= ( 1,25 + 14,75 ) + ( 2,75 + 13,25 ) + ( 4,25 + 11,75 ) + ( 5,75 + 10,25 ) + ( 7,25 + 8,75 ) + 16,25
= 16 + 16 + 16 + 16 + 16 + 16,25
= 16 x 5 + 16,25
= 80 + 16,25
= 96,25
Ta có:1,25+2,75+4,25+.............+14,75+16,25
=1,25 + (2,75+16,25) + (4,25+14,75) + (6,75+12,25) + (8,25+10,75)
=1,25 + 19 + 19 + 19 + 19
=1,25 + 19 x 4
=1,25 + 76
=77,25
