The path of a swooping bird is modeled by the hyperbola 4y^2− 1,225x^2 = 4,900, where x is the horizontal distance measured from the point where the bird is closest to the ground and y represents the height of the bird from the ground. Hint: Assume that the origin lies at ground level. The bird is closest to the ground when its height is meters from the ground.

step-by-step explanation:

times by times

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

$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

is there a question here?
