Answer:

Distance = 8.6

M = (-13.5,27.5)

Step-by-step explanation:

Distance = \sqrt{(x_{2 }- x_{1 })^2 + (y_{2 }- y_{1 })^2

= \sqrt{(-10_ }- (-17)_{ })^2 + (30_{ }- 25_{ })^2

= \sqrt{(-10_{ }+ 17_{ })^2 + 5^2_

= \sqrt{7^2+5^2}

= \sqrt{49+25}

= \sqrt{74}

= 8.6

Midpoint = (\frac{x_{2}+x_{1}}{2};\frac{y_{2}+y_{1}}{2})

= (-10+(-17)) ÷ 2 ; (30+25) ÷ 2

= -27 ÷2 ; 55 ÷ 2

= -13.5, 27.5

The function f(x) = 3x² + 12x +11 can be written in
Viktor [21]

Answer:

3)  f(x) = 3(x + 2)^2 - 1.

Step-by-step explanation:

f(x) = 3x² + 12x +11

f(x) = 3(x^2 + 4x) + 11        Completing the square:

f(x) =  3[(x + 2)^2 - 4] + 11

f(x) = 3(x + 2)^2 -+3*-4 + 11

f(x) = 3(x + 2)^2  - 12 + 11

f(x) = 3(x + 2)^2 - 1.
