An online store advertises 40% off all items and free shipping. Gretta orders a pair of shoes originally priced at $65 and pays
kkurt [141]

Answer:

$42.12

Step-by-step explanation:

Calculation for How much will Gretta pay in total for this transaction

First step is to calculate the new price

New price=$65- ($65*40%)

New price=$65-26

New price=$39

Second step is to calculate the sales tax amount

Sales tax=8%*39

Sales tax=$3.12

Last step is to calculate How much will Gretta pay in total for this transaction using this formula

Total Amount to be paid=New price+Sales tax

Let plug in the formula

Total Amount to be paid=$39+$3.12

Total Amount to be paid=$42.12

Therefore the amount that Gretta will pay in total for this transaction will be $42.12

The second part of the problem is where i need help. The answers i have there have been given by other tutors

SOLUTION

From the given value

Since

\sin u=\frac{7}{25}

Then using trigonometrical ratios it follows

\cos u=\frac{24}{25}

Using hal -ngle it folows

\begin{gathered} sin(\frac{u}{2})=\sqrt{\frac{1-\frac{24}{25}}{2}} \\ s\imaginaryI n(\frac{u}{2})=\sqrt{\frac{1}{50}} \end{gathered}

Also

\begin{gathered} cos(\frac{u}{2})=\pm\sqrt{\frac{1+\frac{24}{25}}{2}} \\ cos(\frac{u}{2})=\sqrt{\frac{49}{50}} \\ cos(\frac{u}{2})=7\sqrt{\frac{1}{50}} \end{gathered}

Finally?

\begin{gathered} \tan(\frac{u}{2})=\pm\sqrt{\frac{1-\frac{24}{25}}{1+\frac{24}{25}}} \\ \tan(\frac{u}{2})=\sqrt{\frac{1}{49}} \\ \tan(\frac{u}{2})=\frac{1}{7} \end{gathered}
