Write y=2x^2-12x+16 in vertex form

leva [86]

Answer:

y = 2 $(x - 3)^{2}$ - 1

Step-by-step explanation:

y = 2 $x^{2}$ - 12x + 16

y = 2( $x^{2}$ - 6x + 8) ( Factor out 2 )

y + 9= 2( $x^{2}$ - 6x + 9) + 8 ( Complete the square $(\frac{-b}{2} )^{2}$ ) Add 9 both sides

y + 9 = 2 $(x - 3)^{2}$ + 8 (Subtract 9 each side)

y = 2 $(x - 3) ^{2}$ - 1 ( simplify )

What area of the grass is being watered by this sprinkler

Novay_Z [31]

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Use this formula:

Area of circle = $\pi r^{2}$

However, as we are using 3.14 for 'pi', we can write it like this:

Area = $(3.14)r^{2}$

'r' is the radius which is 12ft

Substitute this value into the equation:

Area = $(3.14)12^{2}$

Solve:

Area = 452.16

Multiply this value by 0.75 to get the answer:

452.16 x 0.75 = 339.12

339.12 square feet is being watered
