Arrange the equations in the correct sequence to rewrite the formula for displacement, d = vt—1/2at^2 to find a. In the formula,

Murljashka [212]

Answer:

$a = \frac{2(vt-d)}{t^{2} }$

Step-by-step explanation:

Given the formula for calculating the displacement of a body as shown below;

$d = vt - \frac{1}{2} at^{2}$

d = displacement

v = final velocity

a = acceleration

t = time

To make the acceleration a the subject of the formula, the followin steps must be taken;

Step 1: Subtract vt from both sides of the equation

$d-vt = vt-vt-\frac{1}{2}at^{2} \\ d-vt = -\frac{1}{2}at^{2}\\2(d-vt) = -at^{2}$

Step 2: Divide both sides by t²

$\frac{2(d-vt)}{t^{2} } = \frac{-at^{2} }{t^{2} } \\a = \frac{-2(d-vt)}{t^{2} }$

$a = \frac{2(vt-d)}{t^{2} }$

The Nelsons own a home whose market value is $132,000. Their municipality taxes at 70% and the rate is 80 mills or $80 per thous

MrRa [10]

To answer this question you will need to calculate what 70% of the value of the house is because this is what the tax is based on.

0.7 x $132000 = $92400 tax basis

They pay $80 per $1000 in tax basis, so $92400 would be 92.4 groups of $1000.

$80 x 92.4 = $7424 in taxes based on an 80 mills tax rate.
