Answer:

Step-by-step explanation:

In order to find x we use the cosine rule, since we have all two sides and an angle

So we have

x² = ZX ² + XY² - 2(ZX)(XY) cos X

From the question

ZX = 13

XY = 8

X = 93°

Substituting the values into the expression we have

x² = 13² + 8² - 2(13)(8)cos 93

x² = 169 + 64 - 208 cos 93

x² = 233 - 208 cos 93

x² = 243.885

Find square root of both sides

x = 15.616817

We have the final answer as

<h3>x = 15.6 to the nearest tenth</h3>

Hope this helps you

What are the two point plz help me

evablogger [386]

Your first point should always be shown in the y-intercept following the standard form for slope-intercept form

Y = mx + b

b = y - intercept

In this case your first point would be (0,1)

You next point would be following the slope which is -2x. When you graph a equation always know that it is rise over run. For this line, it would be going from left to right since it is a negative line.

Your second point would go down 2 points from your starting point (0,1) and run 1 to the right in the x-axis, which is also called, (1,-3)

Joanna buys a table and 2 chairs. She receives a 25% discount for being a preferred customer and then pays 6% sales tax on the d

Scrat [10]

The total purchase price is $ 357.75

<em><u>Solution:</u></em>

Joanna buys a table and 2 chairs

Cost of table = $ 250

Cost of 1 chair = $ 100

Therefore, cost of a table and 2 chairs = 250 + 2(100) = 450

Thus, cost price = $ 450

<em><u>She receives a 25% discount for being a preferred customer</u></em>

Therefore, discount = 25 % of cost price

$discount = 25 \% \times 450\\\\discount = \frac{25}{100} \times 450\\\\discount = 0.25 \times 450 = 112.5$

Thus, amount after discount = cost price - discount

amount after discount = 450 - 112.5 = 337.5

Thus, amount after discount is $ 337.5

<em><u>Then pays 6% sales tax on the discounted purchase price</u></em>

Sales tax = 6 % of 337.5

$sales\ tax = 6 \% \times 337.5\\\\sales\ tax = \frac{6}{100} \times 337.5\\\\sales\ tax = 20.25$

<em><u>Thus, total purchase price is given as:</u></em>

total purchase price = Amount after discount + sales tax

total purchase price = 337.5 + 20.25 = 357.75

Thus total purchase price is $ 357.75
