Answer:

Tax Amount: $6.40

Tax rate: 4.32%

Step-by-step explanation:

1. To get the tax amount, subtract the cost of the product from the selling price.

$154.40-$148.00 = $6.40

2. Divide the tax amount by the cost of the item.

6.40 ÷ 148=0.0432

3. Multiply by 100

0.0432 × 100 = 4.32%

An equation of an ellipse is given. y2 = 1 − 3x2 (a) Find the vertices, foci, and eccentricity of the ellipse. vertex (x, y) = (

oksian1 [2.3K]

Answer:

Step-by-step explanation:

Given

$y^2=1-3x^2$

$3x^2+y^2=1$

$\frac{x^2}{(\frac{1}{\sqrt{3}})^2}+\frac{y^2}{1}=1$

therefore it is a vertical ellipse

thus a=1

$b=\frac{1}{\sqrt{3}}$

eccentricity of Ellipse

$e^2=1-\frac{b^2}{a^2}$

$e^2=1-\frac{1}{(\sqrt{3})^2}$

$e^2=1-\frac{1}{3}$

$e^2=\frac{2}{3}$

$e=\sqrt{\frac{2}{3}}$

Focii are $(0,ae)$ and $(0,-ae)$

$ae=1\times \sqrt{\frac{2}{3}}$

thus focii are $(0,\sqrt{\frac{2}{3}})$ & $(0,-\sqrt{\frac{2}{3}})$

(b) Length of major axis $=2a=2\times 1$

length of minor axis $=2b=2\times \sqrt{\frac{2}{3}}=2\cdot \sqrt{\frac{2}{3}}$

What are the factors of 2x^2+3x-54? Check all that apply.

Igoryamba

Hello from MrBillDoesMath!

Answer:

(x + 6) (2 x - 9)

Discussion:

6 and -9 are the factors of the constant term as 6 * (-9) = -54

The x term is given by -9x + 12x = 3x (multiply the factorization out)

Answer:

-1/2

Step-by-step explanation:

The line in slope-intercept form,

y = mx + b

has slope m.

In this case, m = -1/2

Slope = -1/2
