Find the length of CD

D

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = C(3, - 2) and (x₂, y₂ ) = D(7, - 8)

CD =

      =

      =

       = ≈ 7.2 → D

Length of CD is 7.2 unit approx Option D.

Step-by-step explanation:

Given,

The two points are C(3,-2) and D(7,-8).

To find the length of CD.

Formula

The distance of two points () and () is

Now,

Putting,

we get,

CD =

= = 7.2 (approx)

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =

$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
