Answer:

a) $15287.71

b) $15017.64

c) $16,368 − <em>r</em>%

Step-by-step explanation:

<u>Mary's car price (including tax): $16,368</u>

[<em>possible tax rates and listing prices</em>]

   <u>a) 6.6%</u>

       ➠ $15287.71

   <u>b) 8.25%</u>

       ➠ $15017.64

   <u>c) </u><u><em>r</em></u><u> (any rate)</u>

       ➠ $16,368 − <em>r</em>%

<u>How did I find my answers?</u>

I had to <em>find the sales tax</em>, and<em> subtract it from the overall cost</em> of the item.

  • To find the sales tax, all I had to do was multiply the sales tax percentage by the price of the item
  • Next, all I had to do was subtract the sales tax from the item's cost

What is the rate of change for a linear function that passes through the points (8, -10) and (-6, 14)
Anna71 [15]

Answer: m=-1.714

Step-by-step explanation:

By definition, the slope of the line is described as "Rate of change".

You need to use the following formula to calcualte the slope of the line;

m=\frac{y_2-y_1}{x_2-x_1}

In this case you know that the line passes through these two points: (8, -10) and (-6, 14).

Then, you can say that:

y_2=-10\\y_1=14\\\\x_2=8\\x_1=-6

Knowing these values, you can substitute them into the formula for calculate the slope of a line:

 m=\frac{-10-14}{8-(-6)}

Finally, you must evaluate in order to find the slope of this line. You get that this is:

m=\frac{-24}{8+6}\\\\m=\frac{-24}{14}\\\\m=-\frac{12}{7}\\\\m=-1.714

Answer the following questions CORRECTLY I will know if this is wrong. I WILL REPORT ANY INCORRECT ANSWERS!
valkas [14]

Answer by JKismyhusbandbae: expression 2 and expression 1

Look at the four expressions. Simplify any expressions that can be simplified to see which two are equivalent.

8v × 30v = ( 8 × 30) × ( v × v) = 240v^2

Since expression 2 can be simplified to expression 1, they are equivalent.

Convert Зcis 180° to rectangular form.<br> А. -3<br> в. -3i<br> с. з<br> D. Зі.
Sunny_sXe [5.5K]

Answer:

-3

Step-by-step explanation:

3 cis(180^\circ) means 3(\cos(180^\circ)+i \sin(180^\circ))

What is the x-coordinate value that corresponds to \theta=180^\circ. That value is -1.

What is the y-coordinate value that corresponds to \theta=180^\circ. That value is 0.

So this implies \cos(180^\circ)=-1 \text{ and } \sin(180^\circ)=0.

3 cis(180^\circ)  

3(\cos(180^\circ)+i \sin(180^\circ))

3(-1+i (0))

3(-1+0)

3(-1)

-3
