5 0

Answer:

Z = 8.8 Y = - 42

Step-by-step explanation:

Y = 2 - 5Z

Y = 5 - 47

2 - 5Z = 5 - 47

- 5Z = - 44

5Z = 44

Z = 8.8

Y = 2 - 5 (8.8)

Y = 2 - 44

Y = - 41

Y = 5 - 47

Y = - 42

In the xy-plane, the line determined by the points (2,k) and (k, 32) passes through the origin. Which of the following could be
alexgriva [62]

1) Considering that those points (2,k) and (k,32) determines one same line, within the plane. Therefore we can say that

2) Considering that since they pass through the origin then their x -coordinate is equal to zero, and their y coordinate as well so

3) We can state that as a matter of fact (2, k) and (K, 32) can be rewritten as (2,0) and (0,32)

k=0

Find the work done in emptying a cylindrical tank filled with water. The water is being pumped out from the 6 top. The tank has
lutik1710 [3]

Answer:

<em>908360.67 lb-ft</em>

<em></em>

Step-by-step explanation:

height of tank= 6 ft

diameter of the tank = 4 ft

density of water p = 62.4 lbs/ft

A is the cross sectional area of the tank

A = \pi r^{2}

where r = diameter/2 =  4/2 = 2 ft

A = 3.142 x 2^{2} = 12.568 ft^2

work done = force x distance through which force is moved

work = F x d

Force  due to the water = pgAh

where g = acceleration due to gravity = 32.174 ft/s^2

Force  = 62.4 x 32.174 x 12.568 x 6 =  151393.44 lb

work done = force x distance moved

work = 151393.44 x 6 = <em>908360.67 lb-ft</em>
