The Work required to pump water out of the spout  would be equal to 464,062.5 π

<h3>How can we calculate the work done?</h3>

Given data :

3 ft, 4 ft, 5 ft A right triangular prism tank with a spout is given.

weight of water = 62.5 Ib/ft³

inner radius ( r ) = 3 x 2 =6 ft

Outer radius ( R ) = 3 x 4 = 12 ft

Height ( h ) = 3 x 5 = 15 ft

To determine the work required to pump water out of the spout

y = Vertical distance

dv = cross-section volume

dw = weight

The radius of the tank

Radius = ( r - R ) y/h + R

Radius = ( 6 - 12 ) y/15 + 12

So, Radius = 12 - 0.4y

dv ( cross section volume )

\pi r^2\\\\\pi (12 - 0.4y)^2dy\\

Weight of cross-section ( dw ) = 62.5 ( 12.5 - 0.4y )² π dy

The work done to pump water out of the spout will be

Work done =  ∫¹⁵₀ 62.5 ( 12.5 - 0.4y )² π dy

∴ Work done ( W ) = 464,062.5

Hence we can conclude that the Work required to pump water out of the spout  would be 464,062.5 π

Point S is on line segment RT given ST=3x-8, RT = 4x, and RS = 4x - 7, determine the numerical length of RT
seraphim [82]

Answer:

20

Step-by-step explanation:

Segment ST is half and RS is the other half. RT is the whole line so adding ST and RS will get you RT. 4x-7+3x-8=4x. solve for x which will get you 5. Replace the x with 5 in 4x (for segment RT) will get you an answer of 20 for the whole line.
