Answer:

x=2,y=2

Step-by-step explanation:

3y-1 = 5

or, 3y = 5+1

or, y = 6/3

y = 2

2x+1 = 3y-1

or, 2x = 3×2-1-1

or, 2x = 4

or, x = 2

\\ \sf\longmapsto \left[{2x+1\atop 2x+x}\:\:\:{3y-1\atop 3}\right]=\left[{3y-1\atop 4}\:\:\;{5\atop 3}\right]

\\ \sf\longmapsto 3y-1=5

\\ \sf\longmapsto 3y=5+1

\\ \sf\longmapsto 3y=6

\\ \sf\longmapsto y=2

Put the value in 1st one

\\ \sf\longmapsto 2x+1=3y-1

\\ \sf\longmapsto 2x+1=3(2)-1

\\ \sf\longmapsto 2x+1=6-1

\\ \sf\longmapsto 2x+1=5

\\ \sf\longmapsto 2x=5-1

\\ \sf\longmapsto 2x=4

\\ \sf\longmapsto x=\dfrac{4}{2}

\\ \sf\longmapsto x=2

Use the method of cylindrical shells to find the volume generated by rotating the region bounded by the given curves about the s
Furkat [3]

Answer:

\frac{16\pi}{3}.

Step-by-step explanation:

I graphed the region in the image below. The blue line is y=3, the purple line is x=1 and the green curve is y = 4x-x^{2}. The shaded region in blue is the region we are going to rotate.

Now, to find the volume  v= 2\pi \int\limits^a_b {p(x)h(x)} \, dx where a=1, b=3 (left and right points of the region), p(x) is the distance from the rotation axis to the diferential Δx, we say p(x)=x and h(x) is the height of the region, in this case is h(x)= 4x-x^{2}-3. Then,

v =  2\pi \int\limits^1_3 {x(4x-x^{2}-3)} \, dx

=  2\pi \int\limits^1_3 {4x^{2}-x^{3}-3x} \, dx

= 2\pi (\frac{4x^{3}}{3}-\frac{x^{4}}{4}-\frac{3x^{2}}{2})^{3}_1

= 2\pi (36-\frac{81}{4}-\frac{27}{2}-\frac{4}{3}+\frac{1}{4}+\frac{3}{2})

= 2\pi*\frac{8}{3}

=  \frac{16\pi}{3}.

Which of the following statements about the image below is true?
kodGreya [7K]

Answer:

The measure of SWX is 108.

Step-by-step explanation:

TX and QS are not perpendicular.

QRT and TRU are complementary (add to 90) not supplementary (add to 180)

The measure of SWX is 108 because angles on a line add to 180, and RWS is 72. 180 - 72 = 108
