Answer:

p = - 8

Step-by-step explanation:

we have to subtract by the number 18p from each of your sides

Like: 10p + 5 - 18p

= 18p -3 -180

This gives us: -8p + 5 = -3

Nextly, we have to subtract by 5 on each of your sides

Like: -8p + 5 - 5

= -3 - 5

This gives us: -8p = -8

Now we have divide by the -8 on each of your sides:

Like: -8p ÷ -8

= -8 ÷ -8

Answer: p = 1

Step-by-step explanation:

10p + 5 = 18p -  \frac{6}{2} \\ collecting \: like \: terms \:  \\ 10p - 18p =  -  \frac{6}{2}  - 5 \\ 8p =  -  \frac{11}{2}  \\ 8p =  - 5.5 \\ p =   -  \frac{5.5}{8}  \\ p = 0.68

Which expression is equivalent to (4−3)−6?
arsen [322]

Answer:

The given expression is equal to -5

Step-by-step explanation:

Given that:

= (4−3)−6

solving bracket first as 4 -3 equals 1

= 1-6

Subtracting greater term from smaller gives the negative value

= -5

So the given expression will be equal to -5

i hope it will help you!

A) Use the method of cylindrical shells to find the volume of the solid obtained by rotating the region bounded by the given cur
Leno4ka [110]

(a) See the attached sketch. Each shell will have a radius <em>y</em> chosen from the interval [2, 4], a height of <em>x</em> = 2/<em>y</em>, and thickness ∆<em>y</em>. For infinitely many shells, we have ∆<em>y</em> converging to 0, and each super-thin shell contributes an infinitesimal volume of

2<em>π</em> (radius)² (height) = 4<em>πy</em>

Then the volume of the solid is obtained by integrating over [2, 4]:

\displaystyle 4\pi \int_2^4 y\,\mathrm dy = 2\pi y^2\bigg|_{y=2}^{y=4} = 2\pi (4^2-2^2) = \boxed{24\pi}

(b) See the other attached sketch. (The text is a bit cluttered, but hopefully you'll understand what is drawn.) Each shell has a radius 9 - <em>x</em> (this is the distance between a given <em>x</em> value in the orange shaded region to the axis of revolution) and a height of 8 - <em>x</em> ³ (and this is the distance between the line <em>y</em> = 8 and the curve <em>y</em> = <em>x</em> ³). Then each shell has a volume of

2<em>π</em> (9 - <em>x</em>)² (8 - <em>x</em> ³) = 2<em>π</em> (648 - 144<em>x</em> + 8<em>x</em> ² - 81<em>x</em> ³ + 18<em>x</em> ⁴ - <em>x</em> ⁵)

so that the overall volume of the solid would be

\displaystyle 2\pi \int_0^2 (648-144x+8x^2-81x^3+18x^4-x^5)\,\mathrm dx = \boxed{\frac{24296\pi}{15}}

I leave the details of integrating to you.
