Write the equation for a parabola with the vertex at (-1, 3) and the equation of the directrix y = 1.
(x - 1)2 = (y + 3)
(x + 1)2 = 8(y - 3)
(x - 1)2 = 8(y + 3)
(y - 3)2 = 2(x + 1)

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
