The sales tax rate is 5%.

Step-by-step explanation:

Given,

Amount of sales tax = $49

Price of dining room set = $980

Sales tax rate = $\frac{Amount\ of\ sales\ tax}{Price\ of\ dining\ room\ set}*100$

Sales taxa rate = $\frac{49}{980}*100$

$Sales\ tax\ rate=\frac{4900}{980}\\Sales\ tax\ rate=5\%$

The sales tax rate is 5%.

Can a regular polygon have an interior angles of 169?

baherus [9]

Answer:

No.

Step-by-step explanation:

If it is a regular polygon then the sum of its exterior angles add up to 360 degrees. The number of sides in such a polygon = 360 / exterior angle.

Here each exterior angle = 180-169 = 11 degrees,

Now 11 is not a factor of 360 and if we try to find the number of sides we don't get a whole number, so the answer is NO.

The solution to $\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)} = 1 + x^2$ is x = 1

<h3>How to solve the equation?</h3>

The equation is given as:

$\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)} = 1 + x^2$

Split the equation as follows:

$y\ =\ \left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}$

$y = 1 + x^2$

Next, we plot the graph of both equations (see attachment)

From the attached graph, the intersection point is (1, 2)

Remove the y value

x = 1

Hence, the solution to $\left(2+\sqrt{2}\right)^{\log_2\left(x\right)}+x\left(2+\sqrt{2}\right)^{\log_2\left(x\right)} = 1 + x^2$ is x = 1
