To get the answer we can use proportion. We know that 4$ its 100% and 4.32 its 100% + taxes.
4$ ---------- 100%
4.32 -------- x
crossmultiply now
4x=4.32*100%
4x=432% /:4
x=108%
We know that 4.32 its 100% + taxes=108% so to get taxes we have to subtract 108-100.
108%-100%=8% - its the answer.

What are the roots of the equation 9x^2 + 54x +82 = 0 in simplest a + bi form?

s344n2d4d5 [400]

Answer:

The roots are

<h3> $x = - 3 + \frac{1}{3} i \: \: \: or \: \: \: x = - 3 - \frac{1}{3} i \\$ </h3>

Step-by-step explanation:

9x² + 54x + 82 = 0

Using the quadratic formula

That's

<h3> $x = \frac{ - b\pm \sqrt{ {b}^{2} - 4ac} }{2a}$ </h3>

From the question

a = 9 , b = 54 , c = 82

Substitute the values into the above formula and solve

That's

<h3> $x = \frac{ - 54\pm \sqrt{ {54}^{2} - 4(9)(82)} }{2(9)} \\ x = \frac{ - 54\pm \sqrt{2916 - 2952} }{18} \\ x = \frac{ - 54\pm \sqrt{ - 36} }{18} \\ x = \frac{ - 54\pm 6i}{18}$ </h3>

Separate the real and imaginary parts

That's

<h3> $x = - \frac{54}{18} \pm \frac{6}{18} \: i \\ x = - 3\pm \frac{1}{3} i$ </h3>

We have the final answer as

<h3> $x = - 3 + \frac{1}{3} i \: \: \: or \: \: \: x = - 3 - \frac{1}{3} i \\$ </h3>

Hope this helps you

One clock of any type costs $3.20. a clocks cost 3.2a. w clocks cost 3.2w.

Add 3.2a to 3.2w to find the total cost.

T = 3.2a + 3.2w

T = 3.2(a + w)

Both expressions above are correct answers.
