Sketch the region bounded by the curves, and visually estimate the location of the centroid. y = 2x, y = 0, x = 1 WebAssign Plot
ASHA 777 [7]

Answer:

the graph is in the attachment.

the coordinates of the centroid : (2/3,2/3)

Step-by-step explanation:

  • y=0 represents x-axis ( you can easily mark it on the graph)
  • now draw x=1 line.( It is a line parallel to y axis and passing through the point (1,0) )
  • y=2x is a line which passes through origin and has a slope "2"

by using these sketch the region.

I have uploaded the region bounded in the attachment. You may refer it. The region shaded with grey is the required region.

  • to find centroid:

it can be easily identified that the formed region is a triangle

  • the coordinates of three vertices of the triangle are

(1,2) , (0,0) , (1,0)

( See the graph. the three intersection points of the lines are the three vertices of the triangle)

  • for general FORMULA, let the coordinates of three vertices of a triangle PQR be P(a,b) , Q(c,d) , R(e,f)
  • then the coordinates of the centroid( let say , G) of the triangle is given by

G = (\frac{a+c+e}{3}  , \frac{b+d+f}{3} )

  • therefore , the exact coordinates of the centroid =

(\frac{1+0+1}{3}, \frac{2+0+0}{3}  ) = (\frac{2}{3}, \frac{2}{3} )

this point is marked as G in the graph uploaded.

Pls answer you’ll get 100 points
Dahasolnce [82]

Take 2points

  • (0,0)
  • (3,2)

Equation in two point form

\\ \sf\longmapsto y-y_1=\left(\dfrac{y_2-y_1}{x_2-x_1}\right)x-x_1

\\ \sf\longmapsto y-0=\dfrac{2-0}{3-0}(x-0)

\\ \sf\longmapsto y=\dfrac{2}{3}x

.

Option D is correct

Y = x – 6 x = –4 what is the solution to the system of equations? (–8, –4) (–4, –8) (–4, 4) (4, –4
fredd [130]

Answer:

(- 4, - 10 )

Step-by-step explanation:

Given the 2 equations

y = x - 6 → (1)

x = - 4 → (2)

Substitute x = - 4 into (1) for corresponding value of y

y = - 4 - 6 = - 10

Solution is (- 4, - 10 )
