Suppose water is leaking from a cubical tank through a circular hole
of area Ah at its bottom. When water leaks through a hole,
friction and contraction of the stream near the hole reduce the
volume of the water leaving the tank per second to cAh2gh−−−√,
where c(0 differential equation for the height h of water at time t. The radius of the hole is 2 in and
g = 32 ft/s2.

i dont know

step-by-step explanation:

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−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
