Answer:

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

Part A: the composite shape is composed of a cone and a half sphere

Part B: The volume of the cone is 1186.92 And the volume of the half sphere is 1526.04

Part C: The volume of the composite shape is the solution of 1186.92+1526.04 = 2712.96

The radius of both the cone and the half sphere is 9 inches and the hight of the cone is 14 inches, using the formula (volume = (1/3) · π · r2 · h) Putting the radius in the r spot and squareing it which is equal to 9x9=82 and putting the hight in the h and turning the pi symbol into 3.14 we get

Volume = (1/3) · 3.14 · 82 · 14

We get the volume of the cone which is 1186.92

Then we use the formula (volume = (4/3) · π · r3) putting the radius in where the r is which is equal to 9x9x9 And changing the pi symbol for 3.14 we get

volume = (4/3) · 3.14 · 729 ÷ 2) = 1526.04

We get the volume of the half sphere which is 1526.04

We then add all of it up to get 1186.92 + 1526.04 = 2712.96

I halved it because it's a half sphere

Find the equation of the line passing through the points (3,-2) and (3, 4).The answer is x = 3. I'm just wondering how my textbo

Leviafan [203]

Given two points. we can find the equation of a line passing through the points

The formula to be used is:

$\frac{y_2-y_1}{x_2-x_!}=\frac{y-y_1}{x-x_!}$

where

$x_1=3,y_!=-2,x_2=3,y_2=4$ $\frac{4-(-2)}{3-3}=\frac{y-(-2)}{x-3}$

$\frac{6}{0}=\frac{y+2}{x-3}$

The next step is to cross multiply

$6(x-3)=0(y+2)$

$6(x-3)=0$

Divide both sides by 6 and make x the subject

x=3

Evaluate the line integral for x^2yds where c is the top hal fo the circle x62 _y^2 = 9

natulia [17]

Parameterize $C$ by

$\mathbf r(t)=\langle x(t),y(t)\rangle=\langle3\cos t,3\sin t\rangle$

where $0\le t\le\pi$ . Then the line integral is

$\displaystyle\int_Cx^2y\,\mathrm dS=\int_{t=0}^{t=\pi}x(t)^2y(t)\left\|\frac{\mathrm d\mathbf r(t)}{\mathrm dt}\right\|\,\mathrm dt$
$=\displaystyle\int_{t=0}^{t=\pi}(3\cos t)^2(3\sin t)\sqrt{(-3\sin t)^2+(3\cos t)^2}\,\mathrm dt$
$=\displaystyle3^4\int_{t=0}^{t=\pi}\cos^2t\sin t\,\mathrm dt$

Take $u=\cos t$ , then

$=\displaystyle-3^4\int_{u=1}^{u=-1}u^2\,\mathrm du$
$=\displaystyle3^4\int_{u=-1}^{u=1}u^2\,\mathrm du$
$=\displaystyle2\times3^4\int_{u=0}^{u=1}u^2\,\mathrm du$
$=54$

Two angles are ____ when they have a common vertex and a common side and don’t overlap.

NISA [10]

Adjacent Angles are two angles that share a common vertex, a common side, and no common interior points. (They share a vertex and side, but do not overlap.) A Linear Pair is two adjacent angles whose non-common sides form opposite rays
