How do I simplify this problem?

Which line has an undefined slope and goes through (5,-8)? A. Y=5 B. Y=-8 C. X=5 D. X=-8

Aleks [24]

Learn this...it helps
HOY = horizontal line, 0 slope, represented by x = a number
VUX = vertical line, undefined slope, represented by x = a number

undefined slope -- so its a vertical line
(5,-8)...remember, vertical lines are represented by x = a number....so we can say x = (now, what is the number for x in ur set of points ? it is 5...so ur equation is x = 5. it does not matter what value y is, x is ALWAYS gonna be 5

Find the taxable income of a married couple with two children, who have a combined income of $75,000.

Dima020 [189]

Answer:

$47,200

Step-by-step explanation:

Given :

The total income of a married couple = $75,000.

Number of children = 2

Therefore to find the taxable income of a U.S. family is given by the following formula ---

taxable income = total income- exemption deduction - standard deduction

We know that exemption deduction for a U.S couple as fixed by the government is $15,600.

And the standard deduction for a U.S couple as fixed by the government is $12,200.

Thus in order to find the taxable income of the couple, use the formula

taxable income = total income- exemption deduction - standard deduction

= $75,000 - $15,600 - $12,200

= $47,200.

Thus the taxable income is $47,200.

Use the shell method. Each shell has a height of 3 - 3/4 y ², radius y, and thickness ∆y, thus contributing an area of 2π y (3 - 3/4 y ²). The total volume of the solid is going to be the sum of infinitely many such shells with 0 ≤ y ≤ 2, thus given by the integral

$\displaystyle 2\pi \int_0^2 y \left(3-\frac34 y^2\right) \,\mathrm dy = 2\pi \left(\frac32 y^2 - \frac3{16} y^4\right)\bigg|_0^2 = 6\pi$

Or use the disk method. (In the attachment, assume the height is very small.) Each disk has a radius of √(4/3 x), thus contributing an area of π (√(4/3 x))² = 4π/3 x. The total volume of the solid is the sum of infinitely many such disks with 0 ≤ x ≤ 3, or by the integral

$\displaystyle \pi \int_0^3 \left(\sqrt{\frac43x}\right)^2 \,\mathrm dx = \frac{2\pi}3 x^2\bigg|_0^3 = 6\pi$

Using either method, the volume is 6π ≈ 18,85. I do not know why your textbook gives a solution of 90,43. Perhaps I've misunderstood what it is you're supposed to calculate? On the other hand, textbooks are known to have typographical errors from time to time...
